What stock Dyno numbers are consistent for the S4

[aka5]

Looking for what stock whp numbers you guys have gotten. Not getting my car on a dyno for a couple weeks(2013 dsg) and am wondering what numbers I should expect before a tune. Not looking for dyno jet numbers sinceThey always tend to read high.



Thanks!

I've seen numbers between 280whp and as high as 330awhp, really depends on what dyno(like you mentioned). The one conclusion that can be made is that these motors are slightly underrated from Audi.

EDIT: I personally dynoed 303awhp on a Mustang dyno when I was completely stock....but I'm pretty sure they adjusted it to read a little higher since it was a large dyno day.

306/308 stock at ICS in CT two years back.

[JMann]

My stock B8 did 305awhp and 319ft/lbs on a Land & Sea DYNOmite in 3rd gear.

[tins5]

FYI I think it also varies based on what gear you're in too.

I think there is more variability in engine output than we account for on this forum. 1 standard deviation could be 10%.

This is why dyno tuning would be better than everyone taking a canned tune from their favorite vendor. The tune the vendor sells you is perfect for the engine they tested it on. It's safe for your engine but doesn't squeeze every HP out of it.

I think what you stated is exactly what the current B8 owner is looking for, faster but safe (leaving something on the table is fine with them). I think as the platform becomes cheaper/older the level of risk acceptable to the owner also goes up and the market for custom tuning will grow as I saw with the B5 community a few years ago.

[vwong]

My car dyno'd at 316.5 awhp and 338.2 lb-ft using a Dynapack in 4th gear.

[chillindrdude]

Please put up the DA for those dyno runs.

[skiracerblah]

Best thing is to find your local dyno shop and get a baseline run before a tune. Once you get a tune, go back to the same exact shop and do more pulls to see the difference.

Even the same model dyno's located in 2 different shops will have some variance...

What he said

I dyno'd 311/296 stock-ish on a mustang (i believe)

This is kind of funny coming from you. Lol

[Pworld]

301 on a Dynojet. Stock. 12k on the motor.

[Skidrowe]

Here is a before and after getting an APR tune and a pulley. It was in February in Nor Cal on a dynojet that was tuned to read like a mustang and was on 91 octane gas with a 91 octane tune.



Here's on 034's mustang dyno in March. Wildly different results.


Don't compare your dyno results to other people's because there are way too many different variables to effectively compare.

only 60whp with a pulley and stage 2? wow for almost 2000 i would feel like i got ripped off

^Doesn't understand what "delta" or "area under the curve" is. ^

Gain at peak isn't the only important number.

Your thoughts would probably change if you raced him lol

[saxon]

Not really, 60whp and the gains are mainly above 4500 rpm. You can say what you want but I'd be upset with only a 60whp increase for a stage 2 "tune"

You really think that 2 identical 3.0T engines running the same gas, in the same conditions could have a 10% variation in power output?? The tight tolerances that engines made today have could never allow a whopping 10% difference in power output capability.

I agree that canned tunes will never have the output capability of a custom tune, but that's not because two S4s have any significant difference in factory power output. The reason we see a wide range of dyno numbers is NOT because of 10+% variation in power output between completely stock motors. It's different dynos, different conditions and different gas.

LOL, what modifications produce massive gains "below" 4500??? Furthermore, when the hell are you racing below 4500rpm?

How about 7-9mph increase in trap speed in the 1/4 mile? Is that acceptable?

[S-Fore]

well, you paid about $165-170 per hp when you bought the car depending on the deal that you got, so $29 per/hp for Stgll seems like a bargain.

Dyno tuning only serves one purpose, it allows a calibrator to make changes in a semi-controlled environment with the car stationary on one place.

Since this is a controlled environment, only a few variables are present. Why do you feel that every horsepower needs to be squeezed out of a motor? Nobody uses all of the power they have on tap the majority of the time.

It takes much more than just a dyno to confirm calibration changes, this is where a proving ground comes into play. The vehicle needs to be placed into real world load situations, on a variety of environments (temperature, humidity, air density, fuel changes).

If you strap a car to a dyno, and make calibration changes to squeeze every last bit of horsepower out of it, you will most certainly encounter catastrophic failure if the engine is presented in an environment to which it cannot adapt to.

Do a race with a stage 2 car from 2k-7k in 3rd gear. If the Stage 2 car doesn't put 10-12 car lengths in that one gear I'd be surprised.

[F16HTON]

Back on track, 91 octane 301WHP (dynapack hub dyno) from 5200-5900RPMs, then the power falls to 270WHP at 7000

[F16HTON]

only 60whp with a pulley and stage 2? wow for almost 2000 i would feel like i got ripped off

The 60HP gain is the peak to peak gain. There is over a 90WHP increase for the stage II upgrade at 7000RPMs

No, what he's saying is even more ridiculous. 1 standard deviation is 10%, so if we take the "middle" 70% of all S4s (meaning, those with the least deviation from the average HP), there will be a 20% difference between the best and the worst. Meaning, ~65 HP difference. This is the same mathematically illiterate trash he's always been saying.

It's difficult for a B7 RS4 to lose 65 HP. That means some serious carbon deposit buildups. It is absolutely obnoxious to make the claim that new engines from the factory have such a large deviation. It violates laws of physics. It's equivalent to one cylinder not even firing, making your engine a 2.5T. I can't describe how absolutely ignorant this statement is.

338 whp-308 wtq Mustang Dyno

GIAC Stage 2 w/ AWE Pulley installed next Tuesday, August 18th. Same dyno a week to 10 days after that.
