034 Motorsports HFC makes 27HP/33TQ on a stock tune 2.0T?

[danbfree]

034 Motorsports claims on a STOCK tune that their HFC will make 27HP/33TQ:

https://store.034motorsport.com/high...-2-0t-fsi.html
"...can provide gains of over 27WTQ and 33WHP on stock turbo tunes."
"We've seen gains of over 27WTQ and 33WHP on our dyno on stock turbo tunes."
https://store.034motorsport.com/medi...son_New_sm.jpg

So, they show the car hitting 16.88 psi of boost... Really? Would just that mod really free up a stock tune turbo to make that much boost? I thought most Stage 1 tunes hit 18 psi, that seems awful high. I'm sure there has to be other mods done, like exhaust and intake, but really? A stock tune allowing that much boost?

I was going to send them a question, but does anyone know the truth here?

"stock turbo tunes" - aka tunes using the stock turbo not a stock ecu file.

So simply a tune on the stock K03, got it! Funny how the wording can make a big difference. They should have just said "stock turbo" as they are implying a stock tune the way it's worded.

Well hey, it's worded like absolute shit and is pretty deceiving.

Yes, exactly, if they mean stock turbo, performance tune, then don't mention tune at all, but instead their word it in a very deceiving manner.

So they definitely should have worked it different, AND listed the tunes/mods used. Instead, it looks like they are being intentionally deceiving. I wonder what the gains are with no other mods at all and with a tune.

I noticed a bigger difference after installing my HFC than I did with just a stage 1 tune.... way back when I had my B7 that was... The HFC was the best mod I did

[LINDW4LL]

I think their wording is quite clear, personally...

You know, I hear that alone makes a big difference, the stock cat is THAT restrictive that I'm probably going to do the HFC for my first mod. I just hope that I don't get any CEL's but tags are good for almost 2 years so I'll have time to get to Stage 2 to clear them. :)

You know, going back and reading it, I can see where you're coming from... but for those who are aren't familiar with "tunes", I still think it's a little confusing.

[konarider94]

Agreed.

And to the op I can see how you mixed it up so easily. Just own it and admit it was a funny mistake at least for the rest of us.

Just stop thinking about it and get both HFC and a tune and be SUPER happy your car is no longer granny-status. I miss my HFC a lot.

It's still misleading when they don't even say what mods/tunes they used to get those results... I want to know what the gains are with zero mods too... I'm also flat out curious what stock, HFC and test pipes each does for an otherwise stock car, in gains and how much boost is gained... I'm doing a GFB DV+ to go along with my mods, of course, I'm thinking since I can't drop $1200+ all at once it would be cool to compare and contrast my options for what I do first and then later.

I had to blow my wad getting control arms and struts done first, I can't do both mods at once. :( Preferably, I'd like to do a GFB DV+ and HFC first and then tune later.

[slappomatt]

test pipe is cheaper. ;)

[Charles.waite]

a HFC is only going to make the turbo spool faster if you're stock. You're not going to be able to take advantage whatsoever of the higher flow potential because airflow and boost are metered by the ECU. You'll get quicker spool, but no more peak power.

I know, I'd put one if I was doing any actual "TESTing" at the track. :)
I just have no intentions of running completely dirty, it's going to be a daily driver eventually that I cart my 8 year old son in, I don't need the smell and soot. I'd rather spend the money on a product that at least runs "clean enough" like any car on the road should, while still providing much more flow over stock.

I think with the massive turbo lag there is from a stop or from a slow roll to hard acceleration, that may be worth it alone.. It seems like sometimes it takes like 3 full seconds before there is any power after flooring it, almost dangerous!

I know.. I'm sure they aren't trying to flat out deceive, but they should at least be more transparent in the mods needed to get there.

Maybe not flat out but "somewhat". If you omit certain details. What would that be Guess its like selective memory

[krewbrew]

Dan, it has been said numerous times in many of your threads... get a tune! Your motor needs more boost to make more power. That is the first mod to make. Really.

I don't care about more power more than I do about drivability, getting rid of horrible lag first... Will tune fix that?

[Charles.waite]

No a tune won't help that. When does your turbo spool up? Should be hitting 11psi by 2000-ish rpms.

[vce1232000]

No tune willBut getting a newer S4 with a SC V6 will ...

[Charles.waite]

^^^ 3.0T swap!!!!!!

And to be honest if you think our cars are laggy you should try driving a 1.8t B6. Good lord those engines have ZERO power below 2600. Makes our cars seem peppy down low in comparison.

Given what you're saying though about the delay even when you're in boost, really makes me think you've got a boost leak or an issue with your turbo. When you're above 2500 the turbo should spool pretty damn instantly.

hehe, my B6 was a 3.0, complete beast but too slow for how much gas it used... Anyway it seems to pull really strong once it's hit power but man, like at least a full 2 second of not longer delay when flooring it, especially if coming around a corner about 5 mph and then flooring it.

Well I have a 034 hfc for sale if current interest doesn't fall thru, just saying. Check out classifieds.

I def felt (felt) a difference with the hfc and no tune. Butt feelings and it was noticeable for that matter. Just saying again. Lol

[Okedokey]

Yeah, I definitely felt the difference and heard the difference.

A tune will improve torque and horsepower at low rpms (2,000 +/-), but it is still a turbo car and will have some lag. APR has good graphs that show this, although other tunes will be more aggressive and provide more benefit. I believe it will improve lag more than a HFC on a stock car. This assumes your car is working properly (no boost leaks or other issues).

Thanks for the input... I recently did the "throttle position reset" so I'm trying to adapt it to not have so much delay, it really seems like a throttle thing to start with, not regular turbo lag. The car did receive lots of the TSB updates for intake flap motor, PCV/breather tube, coils, "fuel pressure sender" (LPFP?) in its first 50k and ECU flashes early on.. What scares me is at 80k it got an "engine assembly", Camshaft remove and reinstall, HPFP, and lock carrier (cam follower?) loosen/fasten, sounds like a complete cam follower failure, I wonder what the "engine assembly" is, if it's a whole new motor due to cam follower failure? In any case, the engine seems very healthy, idles and runs smooth, just the total granny "floor it and wait" that bugs the crap out of me... I figure if the HFC can be done for less than a tune it would at least reduce lag and be more responsive to start with.

I'll check out your ad, and thanks for the direct input on having HFC with no tune, it sounds like it at least helps responsiveness for sure.

[danbfree]

Yeah, I definitely felt the difference and heard the difference.

Thanks for your input too, I really want at least better responsiveness, the car actually pulls quite decently once the power has kicked in... I'm pretty sure I'll do HFC first then tune with a DV+ next.

[kil_ling]

Sorry, the hfc just sold. Good luck with what u decide on.

fyi European Car did a test on the RAI downpipe and came up with similar results. The numbers are pretty close between this article and what 034 claims. I already had a stage 1 tune when I installed the downpipe on my car and it was quite noticeable. Not to drag up old demons, I know rai isnt popular on here anymore but I really like their downpipe. Specifically the fact that they taper from full flow at the turbo flange to 3" instead of having a sharp transition right at the flange. I run cfd analysis enough to agree that has a pretty big affect on the boundary condition for flow area. I know people had fitment issues with their products among others with bigger builds, but I was fortunate.

So coming off the turbo would be either cat or test pipe, downpipe comes after... So you mean a test pipe... I like how JHM does the big diameter opening right off the turbo and tapers down as well on their test pipes and HFC, and also positions the cat itself as far back from the turbo as possible.. But then it is also 300 cell cat vs. 200-250 most race cats are... Decisions, decisions!

OK, as far as the RAI, it's a HFC and downpipe option and looks great! Definitely a nice full exhaust option, impressive gains at the wheels, saves weight and spools turbo much faster... very impressive overall.

Edit: RAI doesn't off the Tip downpipe anymore.. they now sell the HFC alone for $375 with all hardware and spacer included, they claim CEL-free... yet another worthy HFC option!
