JHM stage 2 93 oct hpfp dyno

[Rulty]

So I had off yesterday and Decided to get my car dynoed since I have all the bolt ons until I go big turbo.



I'm a little disappointed with these numbers, as I saw other dynos where the torque was closer to 300 and the hp was closer to 230-250. I must say though I'm still in love with this car. It would be interesting to go for a ride in someone else's to see if it was more likely to just be that dyno or if it really is my car under performing.

This is why dyno's are not a great measure of comparison. There are just way too many variables that heavily affect the results (temp, altitude, calibration, brand, etc. etc.). Dyno's are great for same vehicle, same dyno, back to back pulls with tuning adjustments made along the way to tweak and optimize you tune but are not a good basis for real world performance. Most commercial dyno specs for products are generic curves and more marketing based than actually performance based (most show to the crank which inflates your at the wheels numbers... i.e. APR marketing dyno specs.)

I tend to agree with JHM in their stance for using the 1/4 mile times as a better basis of performance of a tune. You could craft a tune to have max HP and torque but drives like sh*t or you can craft a tune that maximizes performance to get you from point A to B the quickest. I want the latter since that is what performs best in daily driving, track driving, 1/4 mi etc.

[Rulty]

I understand dynos perhaps I got a little antsy with such low numbers, either way I still love the way it drives and I am happy with my performance :) always want more though!

Do you know what type/brand of dyno this is? I'm liking the peak torque at just over 3300 rpms!

Sorry i thought i got the full sheet in that pic, it was on a mustang dyno, dont know specifics. and I hate peak torque at 3300, its all down hill from there :(

[rongeur]

The torque peak is due to the smaller displacement and small frame turbo constraints, not the tune. Time to go big turbo if you want more, but careful what you wish as the K03 is a fantastic turbo for very little lag and around the city zippiness. Larger turbos may offer a more domed / plateau torque curve but typically have much more lag to them.

Sounds like a recipe for the OP to a KO4

[Rulty]

Ill probs kg jump on JHM band wagon and go their stage 3 kit tbh I know I'll want more power than the k04 will push out

KO4 is more geared for urban traffic conditions. BT STG 3 turbo's are designed when you can it on the higher rpm band. It all depends on what your ing for and how and where you
High end power doesnt mean much when you cant extract it when you need it

[rongeur]

Since I have the JHM Stage 3 kit, I feel it is a worthy upgrade. I have a GTX setup that I can make work (GTX2863r) and I may do so in the future if I want to take on the challenge of tuning myself, and making a new down pipe etc. The JHM package is a nice OTS option for BT. There is definitely low RPM lag but hitting 18PSI by 3000PRM and 22ish by 4000RPM and holds until redline is nice. I do miss that early off the line zippiness although, WOT in 1st will snap you back in the seat really quickly. The biggest difference I note in daily driving, if I need a quick pass and I am cruising in 6th at 2000rpm, I used to down shift to 5th and be fine, now I will go down to 4th, maybe 3rd... then it's bye felicia

The JHM is a competitively priced package for someone who does not want to go the custom build route. After getting tuning from JHM I have to say they are top notch and customer service is o.k., though your experience may vary. This time around, I will probably go with the twin scroll 7163 setup. Looks like it still decent for city driving.

[Okedokey]

So does that say less than 200HP at the wheels. That is a bit disappointing.

This guy knows what's up. The 7163 in twin scroll has k04 like spool with BT top end. I'm still in the process of tuning mine, but it has greatly exceeded my expectations.

[NolanB7]

Bummed to see this. Have been on the fence about who to go with stage 2 wise. Can't choose between Eurodyne or JHM. Anyone know of any a4 pulls with eurodyne v jim tunes?

[vvenom800tt]

Dont mustang dynos read low anyways?

[NolanB7]

Op, Little off topic. But What cam follower conversion do you have? I have read about a few supposed fixes. But heard nothing as a solid fix for the cam follower.

Routine maintenance, every other oil change interval replacement.

[Rulty]

It's a roller follower.. I checked it recently, have hard it on for a year or so and absolutely no wear

Thank you Rulty & Aluthman for letting me know, def gonna check out that Iabed Conversion Kit.

[Rulty]

All I'll say is its expensive and the only reason I got it is because I'm lazy and didn't feel like checking my cam follower every 10k miles. If you don't mind changing your cam follower, then don't get it.. It just doesn't make sense from a money stand point. If you are lazy like I am and want the reassurance that it will not just blow through it. Then spend the money and rest easy at night.

How many miles on it so far?

[Rulty]

Youre killing me with that question is say 18k would be on the conservative side

I've thought about getting it, but haven't seen any long term test results. I'm glad to see that it's doing well so far.

I considered myself also. Yes its cost some $$$$. But if its as reliable as its marketed it be and you have some $$$$$ into your build. Its worth the stretch imo. In the long run its worth it just to have peace of mind.

Those numbers look sad... Stock 2.0t is suppose to be close to 200hp, from what I have read a Stage 2 93 should be pushing 270 with the right add-ons.

I dont think they sad. I think is okay. Remember there is about a 25% loss of power from the quattro from the flywheel to the wheels on the car due to drivetrain loss. Higher if tiptronic equipped. So a stock 2.0T on a A4 would read about 170-175 awhp. He's reading about 196ish awhp. The type of dyno and car mods will give different #'s. Mustang dyno's are not known to be the most accurate either

Only has surface scary he's from running on the cam. Absolutely zero wear and I'm in the upper rpm range a lot

On the positive side on the dyno chart, the hp holds at maximum all the way to redline. Other tunes drop off after 5500 rpm or so. Peak hp does seem low though. I would have expected closer to 230 to 240 awhp as said earlier.

[vvenom800tt]

JHM stage to has been over 240whp on some members cars. Although on better dynos.

Anything with mustang in the name is a disappointment, lets be honest

Hmmm, even this ???

[vvenom800tt]

It took them 50 years to make a 5 liter V8 that has over 400hp. Sad

BMW did that 15 years ago, ill take an E39 M5 over that any day

really? my previous car was a 662 HP Shelby GT500, and that engine was at the time the most powerful V8 made by any brand in US, with a factory warranty, ever.

My Gt350 runs rings around a E39 m5, actually it just did a week ago at NH Motor speedway... The only cars passing me were a couple of race prepped 911's.

Remember, it's not all about the power, it's also the balance, suspension, etc. M5 is not a sports car nor can qualify as a track car, although people seem to be stubbornly taking them to the track... I know, I owned 2 of them (E39 and E60).

[vvenom800tt]

I never said the M5 was a sports car. I simply talking about the efficiency of the engine. Which is the only thing i was comparing, you're taking it out of context.

Your shelby is also not NA, so you cant really compare them. Thats like saying the V8 in a Ferrari 488 is better than the V8 is a B7 S4. Duh

Most V8s are better than the 4.2 found in the B6/7 S4.

It's likely the dyno not your car. You would need to have another car with your exact setup to run on that same dyno in identical conditions. Every dyno is going to give different results. Some read high, some read low. Some even read pretty accurately but you need to have 1/4 mile info to compare with the dyno to see which dyno is reading most accurate.

[Rulty]

Thanks for chiming in Jake! Like I said I'm disappointed with the numbers, but they are only numbers! I love my car and the way it drives! I also get compliments from my friends about how impressive the performance is, although its not quite up to par with theirs.... Yet ;)

Also want to say this is nothing against JHM. Just wanted to post up a dyno and hopefully get a little more info out there about how the tune performs, the only thing I take from this dyno is the curves, not the values.

It is nice to see it pull all the way to redline
