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 and not the version you can buy now. Both the apr and revo plots 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.
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 no losses vs 2 revo cars that made over 320whp on the same rollers on the same day and funnily 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. 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
not trying to stir the **** - stating facts.
