The Official B7 A4 Dyno Thread

[AudiB720TS]

This is on a ROTOTEST dyno showing metric horsepower and torque in Nm, at the wheels. Dyno run was cut short because the operator said he noticed knock, and engine surge (see my thread in signature).
Nonetheless the numbers seem fairly healthy for Stage 2, no?

Adjusted for US numbers: 225.7 AWHP 272.2 lbs/ft Torque

Mods:034 HFC, Milltek Sport exhaust (2.5" ID), Autotech HPFP, BMC panel filter, GFB DV+, Bosch F5DP0R plugs, silicone turbo inlet hose, JHM Stage 2 tune (US 93)

[i3oricua]

Two dyno sheets. First one was my JHM tune, no meth, but nearly every bolt on you could get including, upgraded HPFP, catback, test pipe, intake.

This one is with my current setup, EFR 7163, stock internals, stock clutch, meth, S3 injectors

JHM K04R and GIAC software. Other mods in my sig.



Best HP per 3 runs 270.22
Best TQ per 3 runs 293.83

Runs were done with some 100 octane mixed in because of winter gas in New England.

Thats a torque monster right there!! Looks flat for like 2000 rpms 😱

Don't forget its Nm though.

[EvolutionArmory]

I’m not even talking about peak numbers though. I’m talking about the fact that you’re making 275-290 wheel torque for most of the power band.

Look at my dyno. I miss 300 by a hair at 3k and I’m down to 250 by 5K. Your car doesn’t taper til 5K. 🤣🤣 My car made 3 or so more wheel torque but you hold it for what seems like forever 🤣🤣🤣

Like I said, it’s a torque monster. The torque curve is impressive.

Some comfort in that then.

[EvolutionArmory]

I hope it really is. You have 3 dynos and 3 different sets of peak numbers. Peak numbers are for bragging rights. What shouldn’t change from dyno to dyno is how the powerband looks as a whole.

I’d really like to see any MAF logs you have and some Draggy info would be cool. Looking at that data would help see what your car really makes for power. Your trap speed at the end of a 1/4 mile on a nice and flat stretch of road might be more accurate than a dyno because it’s your car on an actual road. And peak MAF data was almost identical to my peak WHP figure on the dyno I used so for my car, any change in peak MAF should equal a power increase of some sort (not really scientific). Since the dyno my MAF went from a peak of 270 GS at redline to now making 270 at 6K and making between 270 and 280 between 6-7K. I’m flowing more air for longer. This data matters. 😀 It’s logical to say I may have picked up 10 WHP since my last dyno.

If you can do a 112-113 MPH consistently then you have a 400 CHP car. 107-108 puts you around 350 CHP. Those numbers are based on 3600 pounds with you in it.

Hi guys, just wanted to share my car and dyno numbers. Mod list: jhm stage 3 turbo kit with fueling upgrades, jhm test pipe, jhm large core fmic, ecs light weight flywheel and rs4 clutch, apr flap runners delete. The car was tuned by boosted euro reaching 22psi car still on stock internals DB8A626F-3F4B-496E-938F-3C723B3EE0F1.jpgF5A3482C-05F5-4B33-A0CD-650F2F1052B5.jpg

Finally we get a JHM TD05 dyno. Thanks. I’ve always wondered what that turbo really makes for power.

Yeah I looked everywhere for dyno numbers before buying it, but never found nothing I had to find out myself and hope anyone can find that useful. the car still can push some more power if a get water/meth kit and a s3 map sensor

[EvolutionArmory]

Yeah, you’re basically maxed out at 22 PSI with the stock MAP. The TD05 is a good match for our displacement and I’m sure there’s more you could squeeze out of it with the right tweaks and fueling.

[texasboy21]

Those peak figures look good, but those hop and torque graphs look funky.

[jamerican1]

I need to get mine dynoed. I have the JHM tune though. I'm also interested in W/M and the S3 map sensor

If E85 is around you throw a E50/E55 mix in the car.

[EvolutionArmory]

The closest E85 station is a 120 mile round trip

I don’t have enough fuel pump to run that much E even if it was close.

What pisses me off the most is E85 is less than 3 dollars a gallon at a pump but if I ordered a 55 gallon drum of it it would cost 7 dollars a gallon plus shipping.

When you get it from the pump it’s mixed with 87 but when you buy it by the drum the mix it with 100. The stuff in the drum is a lot better but you pay for it.

At that point I should just buy a drum of straight ethanol for 1500. That should last me 2 years. Probably only need a half gallon per tank with 93 octane gas and meth.

Thoughts on that?

Just realized that this thread exists. Here are my Dyno numbers on crappy Canadian Shell 91 Fuel .

That’s a solid gain over APR stage 2. What’s your timing look like on crap Canadian 91 octane?

Could be I’m tired and reading it wrong but isn’t he peaking before 4K RPM? What’s up with that?

[EvolutionArmory]

Not sure what you mean?

You’re probably looking at the torque curve

Hi,this is mine,stock 200 hp,torque 250nm

What does the s3 map sensor do . As I’m doing a s3 k04 064 turbo upgrade from a tfsi 220bhp with forged bottom end up rated hotpot s3injectors fmic and clutch etc . Looking for 350bhp 380nm torque hi flow cat and full miltek system

[EvolutionArmory]

The stock MAP sensor is only 2.5 bar. The ECU can’t see any boost over 22.5 PSI. If you get a 3 bar sensor the ECU needs to be tuned for it. If you’re running less than 22.5 PSI, you don’t need it.

Motoza tune. 91 octane and meth, whatever Fort Collins elevation is (5003 ft) on about 25lbs boost. Unfinished tune. Will report back at a later date hopefully if it doesn't blow up.

Do you have the stock 2.5 bar or the S3 MAP sensor like EvolutionArmory is talking about?

Stock sensor. Not the S3 one.

Thanks,
Its the LOBA LO400L still, no WMI.

Healthy is debatable as I am tracking misfires above 6.5K, but work in progress!
