dynos. You may have fared OK in the testing below. Thanks.

Hyperflow induction kit, APR downpipes, and Milltek non-resonated catback exhaust?! (this is assuming 1.28 multiplier to get from whp to bhp.

wow! what exactly is this "Hyperflow induction kit"?

before we could to a bone stock run so I was upset about it. The dyno was broken for about 3 months so we were screwed and I wasnt waiting around. Luckily this dyno is used for testing of several new products to the market on multiple Audi vehicles that have all been baselined including several of my other Audi vehicles I have had with me. Several S4 cars as well. We actually had a B7 S4 sitting up there just today. Given the dozens of baselines it appears the dyno loses an average of 22% drivetrain loss on the quatro manual cars.

It is a venturi metal adapter that goes to an enlarged conical intake cone with interior and exterior pleats then heatshielded from the engine compartment and grabbing air from the OEM front snorkel and the fender. It is similar to many intakes out there. Keep in mind, I have a new fuel filter in the car and am using a light 0w-30 oil with 44lbs of reduced weight on the front brakes and 35lbs reduced in wheel weight. Not sure if that made a difference but perhaps.

FWIW, I believe the biggest gains are coming from the APR downpipes with their very high flow 200cpsi cats. For example, there was another S4 there today with the Milltek downpipes/cats on it and the sound was night and day difference although we had the same milltek catback on the car.

You've got some nice numbers. If your dyno loss of 22% is correct, then you're making the same power as a stock RS4.

except with much more torque

IIRC, he's using GC (castrol 0w30)

but having said that who knows if you lose 22% on stock cars if it is really fair to add that 22% to the modified cars. Its what we all have done so at least it is consistent which is good but who knows how accurate it is. I like to do it to give me an idea but then maybe chop 5% or 10% off of the resultant number just to be conservative.

As Dave mentioned I am using a 0w-30 Castrol European Formula right now, but changing it out every 2-3K miles. I may try a new oil coming out by motul this year called the 0w-30 x-lite.

was your 13.2 with all those mods?
