I was at that same rolling road day.
To be fair, the plots on my car were very similar to the APR Golf R that was there - mine was running the Revo Beta code that was added to try when Revo were developing the current version - i never got round to updating it for one reason or another. Both the APR and Revo plot from my car were pretty nice.
My car was missing a bit of boost that day which was fixed soon after by way of replacing the uprated boost pipe with the standard pancake deal and tightening the connections - there was oil weeping at both sides of the intercooler. As I understand it the new owner made 10bhp more fly hp and a few more wheel power on the same rollers just recently on a warmer day.
WeeG's plot with the new Revo Code was awesome - the torque curve was lovely and flat and ultimately his car made the most wheel power on that day. In my eyes it got the best result as the area under the curves was the largest and the power curve was the most progressive and torque curve was the flattest.
Regarding comparing calculated fly wheel hp between a APR Golf R which had the rear wheels disconnected to run on a 2 wheel rolling road and converting 302whp to be 364fly bhp despite the fact it was impossible for it to be making the losses it would have made had it been driving all 4 wheels (and they were clearly still calculating in those losses) vs 2 Revo cars that made over 320whp on the same rollers on the same day and made 0.3bhp and 0.6bhp less than the APR car at an APR dealer - not sure how that works or how it was set up to calculate, but the fly wheel bhp results were not apples for apples. Not stating for a second that the rollers or the operator were wonky or dodgy - it was a pretty sweet set up and the guys there were all sound.
Nonetheless, the slow time and terminal done by the Golf the following day indicates either;
1) The guy cant drive
2) The car had an issue
3) The performance isnt all that on the road
4) A combination of all of the above
My Leon ran faster times at Crail than that Golf R despite having the disadvantage of front wheel drive launches and 2.2 second 60 foot times vs that Golfs 1.8 second 60 foot time. Terminal speeds were close on 10mph different too, partly explainable by drivetrain losses and weight maybe. Regardless, that Golf should have been in the 12's. A Revo S2+ S3 made 12.7 @ 108mph in 2008. That APR Golf R did 13.4 @ 107mph a day after it made 364bhp this year and it had the same 60 foot time as the S3. Same turbo, pretty much same engine, box and chassis.
By the way WeeG - I agree that your signature is **** - its too big for a start and out of date
. Get it sorted!
