3,000 to 8,000 3rd gear test,

[rs4lee]

Well just left the rolling road, results are pretty much what I expected, 360hp at the wheels, fuel mixture perfect apparently. Looks like I'll be doing a carbon clean soon

Can u clarify 360hp at the wheels or flywheel ??

Good point.

Think 20% transmission loss is acceptable for a 4wd car , so if its 360hp at the wheels on a stock car , there is no need for a carbon clean . In fact it would be very healthy indeed 432hp

And that would make the times on the test make sense, will have to wait for his reply about flywheel or wheel bhp and hopefully get some more folks to post some times up.

Could not wait till tomorrow so have been out and done mine, Did 8 runs and the time that come up 4 out of the 8 times was 8.7 seconds couple of just above 8.8 and 8.9 and one at 8.5 and one at 9.7 but think i pressed a bit early on the start on that one so going by the amount of times i hit 8.7 i would say that was my time , Temp was 6 degree's 1/2 tank of fuel and i am 600 feet above sea level flat ground but not dead straight bit of a bend all the way. Now for me that is approx what the testers where getting when cars where new so i think my car should have just about all of its power, ( Arthur this is where you come in) Could do with some of you chaps who know they are running 400 odd to do some tests on there cars and post the results, (know as in been on rollers and told there cars are this or that power according to the rollers) Cheers.

I'd say you are good to go, 600' ASL ~ 10 HP loss or so, plus the bend may have cost a bit
but the cold air will help a bit
how many miles on your car?
ever cleaned?

[MikeFish]

Yeah I'm going to run a few 3-8k tests now to get the average like you said. Then carbon clean as the car has done 68,000 and never had one that I know of. Going to have a read of that thread recently made for carbon cleaning

Arthur, he answered your questions before you even asked them!

Hi Arthur, It's done 55,000 and i don't think its had a carbon clean, I am going to try and find out as it would be usefull for this thread, What power would you estimate my car is running using my times as a guide ?,

[MikeFish]

Oops, ignore me!

[PetrolDave]

hopefully get some more folks to post some times up.

I did this test 3 years ago in France and averaged 8.5 seconds (IIRC) (at 1000ft above sea level and with approx. 30k miles done), repeated it yesterday and also averaged 8.5 (at 100ft above sea level and with approx 60k miles done).

I think mine would have been around the 8.5 mark as just as i was hitting the stop button on the lap timer the car was hitting the rev limiter which is set at 8,250 rpm so i am pressing the stop a bit to late, I think by the time I see the 8,000 rpm then press the button a couple more tenths have gone by hence hitting the limiter,( I think that's why i got the one time of 8.5, I probably hit the button at the right time instead of hitting the limiter before pressing the stop button thus saving me a couple of tenths.) Have you had a carbon clean or been on the rollers ?.

over 400, close to rated power

the needle also lags a bit, so some inherent delay
the needle really moves from 6k to 8k!

washed mine yesterday and took a nice mountain drive
almost 75k miles, solid as a block of granite, no rattles, no sqeaks...solid
best car I've owned (so far), and I've owned quite a few and some acknowledged benchmarks, e30, e36, e46 M3's, etc.

Have you had a carbon clean or been on the rollers ?.

No, and no.

It still sets times that are within factory spec and makes me smile every time I drive it, so why should I bother with the hassle and cost?

my sentiments exactly

my stereo does not replicate sound exactly, but very close
does this diminish the joy of the music? the experience?

the same for the loss of a few HP than can only be used a very small fraction of the time, and in reality can't even be noticed
so should the driving experience be diminished?
imho no

+1 (It must be close to factory bhp if not dead on)
