Just saw this over on Quattroworld:

APR’s Stage 3 Supercharger System Sets the World’s Acceleration Record for the Hi-Revving 4.2L FSI Engine in the Audi RS4 B7 With a ¼ Mile ET of 11.833 Seconds at 117 MPH



Audi’s highly tuned 4.2L V8 as found in the RS4 and R8 has been available to aftermarket performance companies for several years now. The R8 applications have achieved impressive improvements in performance but the RS4 has proven more difficult. The RS4′s cramped engine bay and various other challenges that engineering teams face when attempting to extrapolate more power have caused RS4 owners to feel left behind. Some have even parted ways with their RS4’s for other models with more tuning potential.

However, APR has achieved new benchmarks for the RS4 with their latest revision to their recently released Stage 3 supercharger system.

Further evolution of the supercharger’s intercooler system and a new calibration by APR’s engineering team has resulted in close to 550bhp on pump gas (in fact recent numbers from their latest tune are over 580 HP). Race gas calibrations are in development. Proving the new power makes it to the pavement, APR released ¼ mile videos and pictures of timeslips achieved at Montgomery Motorsports Park, a NHRA track in Montgomery, AL, this past Sunday. A Racelogic Performance Box was used during the passes at the dragstrip and recorded a 3.7 seconds 0-60 MPH, 8.2 seconds 60-120 MPH and the timeslips provided by the race track recorded a best 60’ time of 1.784 seconds.

Videos are expected to be released later today, check back as we will post them once they are available.

What is even better news is that APR has lowered the price of their Stage 3 supercharger kit from nearly $20,000 to only $14,999 and it is readily available. Information available at www.goapr.com.

Thats big.

^ouch, feel bad for those guys that jumped in at 20k. . . . That's almost a $500 difference in just sales tax. . .

[beemercer]

solid work, those are some fvcked timeslips though lol

[RS4POWER]

Very nice! One more thing you can add to "Hulky"

Yea theyre basically saying they revised the kit and made it better and are charging less. They had to have addressed that for anyone who payed the 20k if they care anything about clientele.

Well done apr good times! I've read on other forums etc that the back seats were removed and the car ran on a jhm tune is this all true?fingers crossed the rain stops over here and I may make it to the local strip with mine

[NY07RS4]

^ Back seats were removed, about an 1/8th of a tank of gas, aftermarket clutch, everything else was stock - the tune thing is not completely accurate. The way Jfunkey explained it on AZ I think is correct. APR contracted an OEM insider for some consultation on the tune. That insider also happens to consult & work with (or for, not sure) JHM. It is an APR tune, who they contact for consultative purposes is their business. Essentially, just because someone who works with or for JHM was involved does not make it a JHM tune. Make sense? I thought Jfunk did a good job at describing the situation. Some of the posts from APR people seemed ambiguous and confused the hell out of the majority of the forum members.

Hope this helped clear some things up.

[djpesrs4]

Yes thank you it did! Why remove seats etc? That's not an accurate test is it? Would it not be more appropriate to run the car with all it's fixtures and fittings in place? Although I suppose the rear seats don't weight too much

[Joey]

Rear seats weight what, maybe 100 pounds? I think that would equate to about .1 on the 1/4 time, still putting the car into the 11's regardless. I am curious as to what this car can do with a full exhaust system.

[djpesrs4]

Yeh that's why I said I don't think the rear seats weigh much! Very good time all the same that car with full decat and exhaust should run well

I agree with you, i think they should have done the run with the rear seats in

[jacx920]

an aftermarket exhaust would have made more of a difference then taking out the rear seats...
