Surely the whole point of this thread and I should know since I started it was to say that the standard measurement device so many people are using to say their cars do not perform, i.e. the rolling road, is not as accurate as suggested?
Dyno Dynamics may be good for raw data uncorrected but then puts in a correcton factor that is wrong. Dastek is corrected and pretty accurately. All I did between Paramount and Motoscope was use more V-Power and have an oil change, yet get 38 more BHP. Seriously. Or should I theorise because the r/r was further North and the air is colder and with less impurities it produces better results?
Does that not say enough to most that they are not an accurate measurement? And to those lurking thinking of buying an RS4 or those with a seed of doubt in their minds on whether their car is up to the mark, don't subscribe to this theory they are all underpowered until you invest in a Racelogic or similar GPS timiing box and do some actual 0-60 and 0-100 runs. If it is way off go get it fixed, if not be happy.
RS4's are great cars and there is little better for the size, practicailty and money, for the members here please do not drag the reputation of this car down unless you have some clear, concrete evidence the cars are underpowered; not half data, assumptions and theories.
DRC is an issue and is being fixed. Engine carbonising has effect on air flow but it is still not proven to what level this physically affects power and none of the other variables in Pre and post cleaning were kept constant. And as has been said before Paramount's set up whilst adequate is not a patch on AMD, Silverstone Performance, JD Engineering or other such sealed cell r/r's
Mac4RS, I invite you up to the Dastek road and let's see what your car does on there plus timed runs before pursuing Audi further. If that still shows you are significantly underpowered then fair enough.
I should also add that I realise Porsches et al do dyno correctly and great for them but I am a firm believer that Dyno Dynamics roads are not capable of recording data from a power transmission variable torsion quattro system.
Flame Suit On - Another Rolling Road Day

I was driving with a friend today: he knows cars...
he and I drove to our HS graduation (many years ago) in a 1954 Jaq LeMans commemorative model, aluminum body, knock-offs, etc.
he rides a Bueull, he knows speed
he was surprised at how hard the car pulled when downshifting to 4th at 70 mph...
we were playing with a 2006 vette (license plate read 06 VETTE
)the RS4 was as quick on a roll...he could not open up a gap...there wa only 1 person in the car to boot, 2 in mine...it looked mildly modded too, it had a Borla exhaust...
isn't that fast enough? a 4 seat, awd luxury saloon as fast as a 2 seat, 3200 lb, 400+ HP, w/ 50% larger engine?!
who cares about the HP, no one here knows what it really is anyways...
Since Paramount, my car has been on a Dastek Dyno on two seperate occasions. And yes, way down on power. Remember, I did go to Slough with a problem.Mac4RS, I invite you up to the Dastek road and let's see what your car does on there plus timed runs before pursuing Audi further.

Progress now happening
It gets more depressing as this thread goes on...but I have to agree with PG, if you think your car is down on power - find a like minded RS4 owner near you (post for people on here) and do a few runs....if the cars are as near as damnit, then your car is tip top.
We all would like them faster, and we all get too familiar with the power. Go on hols, come back, jump in...and they feel f**kn fast.
If in doubt..sell it and by a 1000cc bike (you'll never feel slow)

I too agree with PG, although tbh my car is running a lot better since Audi reloaded the ECU and checked/cleaned sensors etc...
Anyway - I love my car! Even with a another fault light on the dash which Audi need to sort!

Just as an update, it may be that my 396 bhp was made with a poorly car, as I have just had my car back from Audi today with two new back boxes and tips as the change over valves and actuators were seized meaning the valves were only partailly opening on 'S' mode.
My flat spot at 5500rpm has gone as verified by by bum dyno and the car pulls really well and makes a far better noise now also with new tips on. 50 miles of driving since I got it back this afternoon and touch wood no black carbon exhaust crap on the tips either. Rear disks are warped but you can't have everything!
So another trip to Motoscope may be required to see if I can get my extra 18bhp now.

I wouldn't under estimate the difference new oil makes in these cars. It is so hard to prove with so many variables but I'm pretty confident that at least 20bhp of the extra horses you found were down to fresh oil. In April it was clear to see the car with newer oil did seem to have better numbers!P_G wrote: All I did between Paramount and Motoscope was use more V-Power and have an oil change, yet get 38 more BHP.

.
Either way I was really pleased to see your numbers guys
and so wish I could have made it.Will have to get everyone together again soon yeah??
Current car..... hmmmmm????

that's great news...I'ld be interested to see if it's measurable...P_G wrote:Just as an update, it may be that my 396 bhp was made with a poorly car, as I have just had my car back from Audi today with two new back boxes and tips as the change over valves and actuators were seized meaning the valves were only partailly opening on 'S' mode.
