JHM Supercharger reviews

[AudiYes]

Hi guys - Very interested in this JHM kit but I would love to see some customer reviews. Please post any before and after dynos, before and after time slips and/or any type of videos.

Is the car night and day after you supercharged it? Is it worth doing it again after you've experienced it first hand?

Thanks

[koolade9]

I drove Dan@JHM's car and that thing moves!! There's a really good write-up on the install over on AR from a guy down in south africa. There's quite a few videos on youtube of guys running their blower as well. Where in the country are you?

Out of curiosity, why are you solely interested in the JHM kit?

Is it the cheap price point?

Out of curiosity, why do you care? Are you a paid spokesperson for AMD? Hope you see what i did there.

OP id contact JHM directly for starters and use the forum search from there. Their kit has an aggressive price point and stage 1 kits have been known to trap anywhere from 114-118 iirc. Asking that question here will attract the trolls and wont get you the info youre looking for as most kit owners dont post on the forums.

[OscarMeyer]

^this.

*edit. Also check out AR as koolaid said, there is one active build going on along with a bunch of other documented builds. The one that's happen right now from across the pond, the owner is doing some awesome work on the install!

[Bootleg25Q]

Out of curiosity, why do you care? Are you a paid spokesperson for AMD? Hope you see what i did there.

No, I don't. I asked a question. That is what automotive forums are for.

No, I am not. In fact I have spent over $20,000 as an AMD customer.


Did I say anything negative about JHM? Nope. I asked a simple question, in a respectful manner, like an adult.

[Bootleg25Q]

Hi guys - Very interested in this JHM kit but I would love to see some customer reviews.

The only person I know in the Portland area that has the JHM Supercharger kit is very unhappy. As is the shop that installed the kit. In fact, that shop has cut ties with JHM because they accused the shop of installer error in regards to the slew of issues that the car is having. This is the 3rd reputable shop in the Portland area that has cut ties with JHM for this exact reason. The kit I am referring to was installed several months ago, and the owner has gotten to drive the car less than 750 miles.

As JDMNOMORE and OSCERMEYER have demonstrated, you are not allowed to say anything negative about JHM on these forums. So, I am happy to pass his contact information along via PM if you'd like.

For me, the choice was simple. I am not cutting vital pieces off of my car and I'm not removing a fog light to fit the centrifugal style supercharger. Both APR and AMD provide direct fit, options that do not require any cutting or sacrificing features of the car.

With that said, it is a cheap price point, can't argue that.

[OscarMeyer]

Kevin your hilarious, how about the countless Facebook post where you name call and act like a child.

I was just saying AR had alot of documented builds, we're did I say you can't say anything negative about JHM? Never less a typical S/C in the RS forums.

*edit... I called them out along time ago, for shitty rotors, which ended up being the shit pads I was using, I swapped to hawks and have had no issues. And I've been open with all my issue's. But you have a personal vendetta against them.

Everyone owns the same car here, why is there so much hate, it's honestly ridiculous.

[Bootleg25Q]

Everyone owns the same car here, why is there so much hate, it's honestly ridiculous.

That's why I made an effort to ask an unbiased question which was met with a defensive, sarcastic remark.

[jdmnomore]

Then you follow up with your next post, classic. And your question was loaded with biast and sarcasm which is why i responded the same exact way LOL. Now do you see what I did there?

[Bootleg25Q]

Then you follow up with your next post, classic.

lol

Again,

I made an effort to ask an unbiased question which was met with a defensive, sarcastic remark.

So there you have it, bud.

[OscarMeyer]

I would say it's because you constantly jump down any JHM owners throat on Facebook and the forums.

But why don't we all stop the banter right here and allow this thread to get back on track?

Hopefully Denis will chime in with his stage1+

[Bootleg25Q]

Then you follow up with your next post, classic. And your question was loaded with biast and sarcasm which is why i responded the same exact way LOL. Now do you see what I did there?

Nice ninja edit, bud.

You are fantastic at making assumptions.

My question was not at all sarcastic or loaded. I simply asked if price was his reason for inquiring about the JHM kit.

If he answers no, then it opens his options up to an AMD or APR kit, which yes, in my opinion are much better kits.

I am happy to clarify anything else if you need, let me know.

[Bootleg25Q]

I would say it's because you constantly jump down any JHM owners throat on Facebook and the forums.

False accusation, and you know it.

I regurgitate the same information that I have about JHM be it the forum, or a social media post.

Dig through my Audizine posts if you would like, and if you do, please show me a post where I "jump down" a JHM customers throat. In fact, that's ironic to say because that is more or less what JDMNOMORE just did. I asked a simple unbiased question in a respectful manner, directed at OP, and he replied to me with a defensive, sarcastic remark.

I'm doing nothing wrong here. I have personal experience as a JHM customer and I have discussed JHM products and customer service with many others that share my opinion. Automotive forums are intended to give people an opportunity to voice their personal experiences, and ask legitimate questions (like OP). I voice my experience, just like you do. We don't have to agree on a favorite product or shop.

[jdmnomore]

No clarification needed lol. Thanks for the compliment. So OP dont have your kit installed in Portland and youre golden haha. Glwsearch

[Gansel]

All this talk of supercharges makes me want one.. who's going to take me for a pull?? (or let me drive....please)

[dufferdude]

Well, I saw this thread this am and I thought to myself, oh jesus here we go again.

[Blue AWD]

Out of curiosity, why are you solely interested in the JHM kit?

Is it the cheap price point?

Honesty I have no opinion one or the other but adding the word "cheap" instead of just saying "price point" makes it seem a little negative.

[JimmyBones]

Well, I saw this thread this am and I thought to myself, oh jesus here we go again.

Yep, I already put the popcorn in.

Honesty I have no opinion one or the other but adding the word "cheap" instead of just saying "price point" makes it seem a little negative.

I agree.

[Bootleg25Q]

Didn't mean to hurt anyone's feelings with an adjective.

I highly doubt that Todd and Mr. JDM are that sensitive anyway.

The kit I am referring to was installed several months ago, and the owner has gotten to drive the car less than 750 miles.

Portland might want to stop smoking so much. Anyway, Boot has no first hand experience with the JHM kit it would seem and only knows one person that had the kit for a very short while because the shop that installed was incompetent. I on the other hand, actually have the kit (on an S4) and I have been running it for nearly 5 years and it's fantastic. The shop that installed it nearly 5 years ago had never installed the JHM kit before and they managed to install it just fine. Strange how that works out. Oh wait, no it's not strange, it's just standard competence.

With that said, it is a cheap price point, can't argue that.

Haters like you might call it cheap, others who know better would call it well priced rather than gouging.

Anyway, OP, as you can see, there's a lot of hidden agendas and ulterior motives from all sides. There's money behind all this and bad blood amongst different "clans" so it'll be tough to get a straight story from anyone. Feel free to check my signature. I've reviewed every mod I have and provide a dynojet dyno, one short pull video against a stock RS4 and one 0-100kph launch video.

Good luck with your decision.

No need to get defensive.

Did I claim to have any first hand experience? I think you misread what I wrote. lol

I know the owner personally, and have spoken with him throughout the build and issues. He doesn't use the forums so I thought I'd pass the information along.

That's awesome you and your shop had a great experience with the kit. As a fellow enthusiast that's good to hear.

Perhaps the shop is incompetent as you say, I've never let them work on my cars. I wouldn't know. It just seemed ironic that there are now 5 reputable shops (that I'm aware of) in the Seattle/Portland area who refuse to install JHM parts. It just doesn't really seem fair to say that these high caliber shops who have been around 20, 30, 40 years are incompetent.

Do you have any mustang dyno graphs or 1/4 mile slips? I don't think I've ever talked to you, so I apologize if you've posted them before.

[dufferdude]

Let's talk about which hood is better for a non SC'd RS4?

[NYC_Legacy]

Well, I saw this thread this am and I thought to myself, oh jesus here we go again.

Same...get the popcorn.

I am partial to the TTS set-up solely because I've seen it spit flames in a number of youtube videos.

[Axel-]

No need to get defensive.

Did I claim to have any first hand experience? I think you misread what I wrote. lol

Where did I say you were claiming first hand experience? Jeesh. Who's the one being defensive. I said "Boot doesn't have first hand experience it would seem" in direct response to you stating you don't have first hand experience. Wow.

I know the owner personally, and have spoken with him throughout the build and issues. He doesn't use the forums so I thought I'd pass the information along.

Yet you know full well there are tons of satisfied JHM customers including JHM supercharger owners. You know this full well because they're here on AZ as well as other very well known Audi forums and have expressed this satisfaction many times. You know this, yet, you choose to only mention one friend of yours who had a bad experience for an unknown reason you've chosen to omit and offered the OP his contact info. Hardly neutral.

Perhaps the shop is incompetent as you say, I've never let them work on my cars. I wouldn't know. It just seemed ironic that there are now 5 reputable shops (that I'm aware of) in the Seattle/Portland area who refuse to install JHM parts. It just doesn't really seem fair to say that these high caliber shops who have been around 20, 30, 40 years are incompetent.

It's very common that high calibre shops think they know best and chose to ignore specific instructions due to huge egos and elitist attitudes and when that bites them in the ass, the last thing they will ever do is admit they were in the wrong and should have followed instructions. It has happened to me a few times over my 20+ years of car ownership in more than one city and I now make it one of my assessment criteria whenever I need to find a new shop for any new car I buy that's not of the same brand as an existing car. The higher the calibre, the more likely they are to "not read the manual" and fuck shit up. It's very common and I consider this to be incompetence (not knowing how to read a manual or follow manufacturer instructions). As a specific example, I went to a new shop 5 years ago to have my JHM short shifter trio kit installed. I gave them the parts and the link to the JHM installation video. When I came to pick the car up, they still couldn't get into certain gears and began blaming the parts stating they must have been defective. I asked them if they watched the video I sent them. They were at least honest and said they hadn't since they had installed tons of short shifter kits over the years for numerous high end brands. I asked them to go over the video together and see if they performed each and every step (at least they were kind enough to humour me). It didn't take long for them to get a light bulb moment at one of the spots in the videos where it said to perform a step they hadn't done (on the linkage piece). They did that step and the kit instantly worked and it's been fine since.

Anyway, that was just a small stupid example of how easy it is for a shop, especially a high end one, to fuck up an install because they figured they knew better. And once they fuck up, it is extremely rare for them to admit to it. Finally, it's a small niche market and all these shops know each other and talk to each other. It wouldn't surprise me if "word" got around to avoid JHM because one or two shops wanted to avoid the embarrassment of having fucked something up. Again, I've seen this occur fairly often. The after market environment for Audis is quite small and full of emotional baggage (which is why you have these shit shows on the forums). The B5s had them, the B6/7 have them, the B8s also have them.

Do you have any mustang dyno graphs or 1/4 mile slips? I don't think I've ever talked to you, so I apologize if you've posted them before.

Unfortunately, there are no awd mustang dynos in my area. There are actually only 3 or 4 awd dynos that I know of in the entire Greater Toronto Area surprisingly. Again, small niche market. These awd dynos are mostly used by subaru and audi owners. As for the quarter mile, my best is 12.5@113mph (S4 Avant running stage 1 at 6psi) with a sticking clutch pedal (the dreaded RS4 pressure plate issue). Although I now have a proper clutch, I haven't had a chance to go back unfortunately. I'm thinking I could have done a 12.2 with a properly working clutch at my skill level and mods but that's just an educated guess.

[Bootleg25Q]

Everyone owns the same car here, why is there so much hate, it's honestly ridiculous.

Well said.

Agreed.

I couldn't care less about everyones preference in shop and supercharger kit. Like I said, I was literally just curious why OP was only interested in 1 option. That's it. Seems this is a hot button for some people.

Let's talk about which hood is better for a non SC'd RS4?

That has already been unanimously decided, Bob. I'd buy your Vorsteiner yesterday if you'd name your damn price, lol.

I am partial to the TTS set-up solely because I've seen it spit flames in a number of youtube videos.

I really like the TTS Kit. I've heard great things from guys that run it.

The AMD Kit meets your criteria as well, just FYI! lol

[Peter1.8t]

Get the JPD Blower. Its like a combination of all three blower kits put together (JHM. APR. AMD). Its absolutely the best and destroys everything else on the market.

That way you can come in here an act like an elitist, make assumptions, hell you can even make up "Facts" if you want to.

Real talk though, I'd still like to see why the JHM kit was singled out by the OP, with none of the other kits on the market being included. Always interested to hear how people come to their conclusions.

Can't help you with the JHM kit, however, if you have questions about the AMD blower kit then you can PM anytime.

[OscarMeyer]

False accusation, and you know it.

I regurgitate the same information that I have about JHM be it the forum, or a social media post.

Really cause I called you out on Facebook, for you berating Olivier after he already had made his purchase's for his RS avant, which btw he was super happy about. (documented on AR)

You keep your comments nice and neat on audizine, because it's very easy to search for posts. Your Facebook etiquette is far from what people see on here. I know a few owners have seen that personally, myself included.

Anyways like I said before no need to banter over this, you have a vendetta against JHM, let's just leave it at that.

No need to get defensive.

Did I claim to have any first hand experience? I think you misread what I wrote. lol

Do you have any mustang dyno graphs or 1/4 mile slips? I don't think I've ever talked to you, so I apologize if you've posted them before.

So you heard from a friend, is that the same with these 5 shop's? Or did you talk to them personally? Any chance you can tell us the names of these shops, or is that secret information? Honest question?

Agreed.

I couldn't care less about everyones preference in shop and supercharger kit. Like I said, I was literally just curious why OP was only interested in 1 option. That's it. Seems this is a hot button for some people.

The AMD Kit meets your criteria as well, just FYI! lol

You couldn't care less but you shamelessly plug your own supercharger. You should quite AMD and work for APR, deflect deflect deflect, you would fit in great!

Anyways like I said above let's quite the banter, Axel has 5yrs with the kit and it's running strong, sure it's on the S4 platform but non the less that's awesome! I believe Denis has a couple years with the kit on his car, and he has upgraded to the stage 1+, and had been nothing but open and honest about it, Sar from the UK has over a year on his kit and haven't heard anything bad from him(granted we haven't heard much at all, but another owner I believe mentioned he talked to him in person and was loving the kit?) a local to me that had the stage 1 kit also loved it and had nothing but great things to say about it, he sold his car to get into a 997 gt3 RS which I can't blame him. I drove that car and the power delivery was amazing just pulled all the way through the rpm band, Made mine feel stupid slow haha!

[sandspeed]

Oh wait, no it's not strange, it's just standard competence.

Do you have dyno sheets? 1/4 mile times are too heavily affected by driver skill and track condition. Just curious to see some numbers.

[Blackstallion]

click his sig...

Goodluck on your decision OP - I'm a fan of JHM personally but have no experience with their kit or TTS AMD APR so ill stay out of this...

[Bootleg25Q]

Really cause I called you out on Facebook, for you berating Olivier after he already had made his purchase's for his RS avant, which btw he was super happy about. (documented on AR)

lol, I literally have no idea who "Olivier" is.

These accusations are so bizarre that they lead me to believe you are mistaking me for another person. Either way, I find it pretty hilarious.

The only "JHM Post" that I recall participating in was Braedon's post about his ongoing issues with JHM's Lightweight rotors.

Is this the post you are talking about? And if so, you may want to re-read it because the entire thread is negative reviews about the slew of documented issues with JHM's lightweight rotors. Don't try and portray me as "berating" anyone. The person that started the post hates JHM.



https://www.facebook.com/groups/2270...4808058634287/

I will post the same thing here, that I posted there because it was not "berating" anyone, I was passing information from the forum to people that do not use the forum:

You keep your comments nice and neat on audizine, because it's very easy to search for posts. Your Facebook etiquette is far from what people see on here.

You really think I care enough to sit here and strategically post "nice and neat" comments on Audizine? Man, that's funny. I don't mean to hurt your feelings, but I don't care about you or this forum enough to do that. I promise. lol

Anyways like I said before no need to banter over this, you have a vendetta against JHM, let's just leave it at that.

You are pretty delusional my friend. You sit here accusing me of having a personal "vendetta" against JHM.

Todd, look in the mirror.

You literally have a vendetta against every company that is NOT JHM, or anyone who supports companies OTHER than JHM.

I have an RS4 with JHM Tune, JHM LWFW/R Series Clutch. I have negative first hand experience with JHM's customer service, as well as their products. I have every right to voice my personal experience with the company and products. That is not a "vendetta", lol.

Serious question: This is one of the first messages I received from the only person I personally know with the JHM supercharger kit. Do you consider this a "vendetta" too? Is he not allowed to voice his experience with the company and their products?

So you heard from a friend, is that the same with these 5 shop's? Or did you talk to them personally? Any chance you can tell us the names of these shops, or is that secret information? Honest question?

I have personal, first hand experience with all of the following shops except Peak Innovation Motorsports, who is still comically listed as a JHM Dealer on JHM's website, but refused to sell or install JHM products going forward.

Matrix Integrated - (503) 443-1141
Futrell Autowerks - (503) 629-5999
Achtuning - (425) 895-0000
Peak Innovation Motorsports - (503) 206-7594
Addict Motorsport - (425) 424-2156

Yes, I said Addict Motorsport. Sometimes competing shops still deal and install each others parts. A perfect example is JHM, who is an APR dealer.

Funny part is, APR is not a JHM dealer, so what's that tell you?

You couldn't care less but you shamelessly plug your own supercharger. You should quite AMD and work for APR, deflect deflect deflect, you would fit in great!

This one is my favorite!

You accuse me of "shamelessly plugging" my own supercharger?



You can't be serious, right?

I have well over $20,000 in AMD products and services on my newer RS4. I post a video of an AMD car (not even mine) and I am "shamelessly plugging"?

Man, you are one deranged individual. I have as much first hand experience as one can have with a shop and their products. I believe in the product and service enough to spend $13k on a blower and over $10k in supporting mods, all installed by AMD. That is not a shameless plug, bud. That is literally no different than you posting about a JHM Tune. You have the product, so you recommend it to others, right? Is that a "shameless plug" for JHM?

Get real with yourself.

Also, what am I "deflecting"? I don't think that word means what you think it means. I am an open book. Ask, and I will answer. Good try though.


Since we are on the topic of YOUR first hand experience:

Do you have the JHM Supercharger?

Is that why you are in here attacking me for my preference in supercharger kit?

If you love the JHM Supercharger kit so much, then why don't you buy it?

With all due respect, here is an idea, why don't you let the people with supercharged RS4's talk about their experiences with supercharged RS4's.

No one here is interested in your ability to monitor a crappy Audi Forum (Audi Revolution) and then re-type what you read there.

I believe OP is looking for FIRST HAND REVIEWS, not some random guy who daily drives a Ford Focus and who doesn't have a supercharger.

You are just a typical JHM bully that attacks anyone and everyone who dislikes JHM.

(DISCLAIMER: If you have a supercharger, please omit this last portion. And I stand corrected. I don't know anything about you, nor do I care to know. So if you do, please correct me. )

[str8blst]

Hi guys - Very interested in this JHM kit but I would love to see some customer reviews. Please post any before and after dynos, before and after time slips and/or any type of videos.

Is the car night and day after you supercharged it? Is it worth doing it again after you've experienced it first hand?

Thanks

It was nice meeting you the other day... good luck with your search.. AS you can tell people here get their panties all in a bunch when forced induction on the RS4 is discussed. I think the only way to decide is to try and drive a car equiped with the JHM SC. As we discussed I love my APR charger. No issues with it and as you saw.. I drive it daily when weather is nice with no issues. Holla when your back in town!

[Bootleg25Q]

Unfortunately, there are no awd mustang dynos in my area. There are actually only 3 or 4 awd dynos that I know of in the entire Greater Toronto Area surprisingly. Again, small niche market. These awd dynos are mostly used by subaru and audi owners. As for the quarter mile, my best is 12.5@113mph (S4 Avant running stage 1 at 6psi) with a sticking clutch pedal (the dreaded RS4 pressure plate issue). Although I now have a proper clutch, I haven't had a chance to go back unfortunately. I'm thinking I could have done a 12.2 with a properly working clutch at my skill level and mods but that's just an educated guess.

Despite what is being implied by Todd Oscar Meyer, I do not have a vendetta against JHM, or their kit.

I have my preference, you have yours. Nothing wrong with that.

I think what you've done with the B7 S4 is phenomenal.

From one enthusiast to another, I am sincerely happy that you are enjoying the car after the blood, sweat, and tears that you likely put into it.

12.5 @ 113mph is definitely moving, especially with just the Stage 1, and being in an Avant. You have a ton left on the table for sure.

I share in the feeling that I may be under performing at the track with my kit as well. I'm certainly not a seasoned veteran drag racer.

The fastest my car has gone was 11.3 @ 123 mph. That was immediately after the kit was completed, and with the owner of AMD driving the car. So I cannot necessarily claim this glory.

To save some time, I am just going to copy/paste this information from another thread, but here is my experience at the track with the car so far:

Win vs stock Hellcat:










Win vs "HyperBlue Stage 3, Bro" STI:






Win vs RS4 - APR TVS1320 Blower (My first drag race ever)




Win vs B8.5 S4 APR Stage 2 (This is my buddy, he ran much faster times this night but this was towards the end of the night. The car was too hot and would not allow him to use launch control)




It was 90* outside and these were my first 4 legal drag races, ever.

My RT's were trash.

All things considered, these are okay times. It was 100% the kit doing the work.

AMD did a phenomenal job building this car.

I had everything set pretty conservative, being my first time drag racing. The launch control was set at 2900, I'll put it up to 3200 this fall when the weather is more boost friendly.

My shifting was flat out sloppy. I was shifting slow, and all over the place. Ideally I shift at 8000, but I'd say at least 50% of the time I was shifting at 8300-8500. I'm just amateur, lol.

Thanks for randomly taking time to show me your car again! It was really a clean install, I'm in town soon and definitely will!

Im asking about the JHM kit because I've read that it makes little more power and has untapped potential. But I was lucky to bump into Str8blst recently and I was surprised he recommended APR over JHM due to the amount of JHM praise I've seen over the forums.

That's why I'm asking for owners' reviews. Price point isn't the reason I'm looking at the JHM kit. Power/torque are the main reasons. If you own a supercharger Id appreciate it if you posted a review of your own SC and some before/after material.

I apologize for unintentionally derailing your thread.

I made sure to post my actual experience with the AMD kit.

The APR and AMD kits are very similar, in fact they both use a roots style TVS supercharger that is direct fit and does not require any cutting.

APR - TVS1740
AMD - TVS1900

I like the APR kit, I really like the TTS kit, I dislike the JHM kit, and I prefer the AMD kit.

Please keep in mind that JHM pays Audizine to sponsor this forum and digital marketing is very effective. A lot of guys that loudly support JHM don't have more than JHM piggy pipes or a JHM clutch kit in their car. In my opinion, that doesn't qualify them to give reviews on the supercharger kit. Keep talking to guys like Str8blst (APR Kit), or Peter1.8t (AMD Kit), or Axel (JHM Kit, on an S4) who actually have experience with supercharger kits.

I scrolled through this thread and happened to see this part so I decided to quickly address it. I don't really pay attention to these threads anymore so anyone can feel free to PM me.

Yes, I said Addict Motorsport. Sometimes competing shops still deal and install each others parts. A perfect example is JHM, who is an APR dealer.

Funny part is, APR is not a JHM dealer, so what's that tell you?

Matrix - First off they installed your clutch wrong then tried to blame it on "shipping damage". Their tech apparently didn't know how to align the splines from the input shaft to the clutch disc and just rammed it it until it wouldn't go anymore. (happy to share pics of the disc. we keep it around because its a serious head shaker) Then they decided to get upset after we would not warranty their installation error after they swore up and down that the splines being smashed in was "shipping damage".

Futrell- LOL those are the dudes that charged mick over a grand for a shifter install, and still couldn't do it. So we installed it for free for him. I think it is better for everyone that they don't install our parts.

Acht- I am not sure. May have been before my time here (2011)

Peak? May want to check your facts because I checked their wholesale account there is still recent activity.

Lol APR is only an APR dealer.. so of course they wouldn't install our parts (even though they DO install our parts on their R&D cars). What's even funnier is that they don't even install their own parts locally anymore! They funnel customers to their dealer network.

lol, I literally have no idea who "Olivier" is.

These accusations are so bizarre that they lead me to believe you are mistaking me for another person. Either way, I find it pretty hilarious.

The only "JHM Post" that I recall participating in was Braedon's post about his ongoing issues with JHM's Lightweight rotors.

Is this the post you are talking about? And if so, you may want to re-read it because the entire thread is negative reviews about the slew of documented issues with JHM's lightweight rotors. Don't try and portray me as "berating" anyone. The person that started the post hates JHM.

I will post the same thing here, that I posted there because it was not "berating" anyone, I was passing information from the forum to people that do not use the forum:






You really think I care enough to sit here and strategically post "nice and neat" comments on Audizine? Man, that's funny. I don't mean to hurt your feelings, but I don't care about you or this forum enough to do that. I promise. lol




You are pretty delusional my friend. You sit here accusing me of having a personal "vendetta" against JHM.

Todd, look in the mirror.

You literally have a vendetta against every company that is NOT JHM, or anyone who supports companies OTHER than JHM.

I have an RS4 with JHM Tune, JHM LWFW/R Series Clutch. I have negative first hand experience with JHM's customer service, as well as their products. I have every right to voice my personal experience with the company and products. That is not a "vendetta", lol.

Serious question: This is one of the first messages I received from the only person I personally know with the JHM supercharger kit. Do you consider this a "vendetta" too? Is he not allowed to voice his experience with the company and their products?





I have personal, first hand experience with all of the following shops except Peak Innovation Motorsports, who is still comically listed as a JHM Dealer on JHM's website, but refused to sell or install JHM products going forward.

Funny part is, APR is not a JHM dealer, so what's that tell you?




This one is my favorite!

You accuse me of "shamelessly plugging" my own supercharger?



You can't be serious, right?

I have well over $20,000 in AMD products and services on my newer RS4. I post a video of an AMD car (not even mine) and I am "shamelessly plugging"?

Man, you are one deranged individual. I have as much first hand experience as one can have with a shop and their products. I believe in the product and service enough to spend $13k on a blower and over $10k in supporting mods, all installed by AMD. That is not a shameless plug, bud. That is literally no different than you posting about a JHM Tune. You have the product, so you recommend it to others, right? Is that a "shameless plug" for JHM?

Get real with yourself.

Also, what am I "deflecting"? I don't think that word means what you think it means. I am an open book. Ask, and I will answer. Good try though.


Since we are on the topic of YOUR first hand experience:

Do you have the JHM Supercharger?

Is that why you are in here attacking me for my preference in supercharger kit?

If you love the JHM Supercharger kit so much, then why don't you buy it?

With all due respect, here is an idea, why don't you let the people with supercharged RS4's talk about their experiences with supercharged RS4's.

No one here is interested in your ability to monitor a crappy Audi Forum (Audi Revolution) and then re-type what you read there.

I believe OP is looking for FIRST HAND REVIEWS, not some random guy who daily drives a Ford Focus and who doesn't have a supercharger.

You are just a typical JHM bully that attacks anyone and everyone who dislikes JHM.

(DISCLAIMER: If you have a supercharger, please omit this last portion. And I stand corrected. I don't know anything about you, nor do I care to know. So if you do, please correct me. )

I absolutely stand corrected I did mistake you for someone else, my appologies, it was the previous owner of your car and Mike@amd . again my appologies.





And thank you for posting the shops, I know competition does sell the others hardware, it's why Apr recommends the JHM clutch with its supercharger kit. Which was used on the hail Mary runs at 10.6.

I stated above I thought you were someone else, hence why I said the shameless plug, stop telling everyone how much you spent, it doesn't mean anything. Did you spend that much or did the previous owner? Just joking on that one, because we all spend stupid amount on our cars, and because I really like how your car is setup currently.

And for the remainder of your questions you can just omit, as I'm giving first hand experience, But thank you for your concern. No not a bully, I had mistaken you and aggressively posted against you, it was mistaken identity, which again my apologies. This was not me moderating another audi forum, it was me actively posting on Facebook.

Sorry for mistaking you, my apologies again for that

Yeah I'll take a cup of coffee with that too.
