Okay, I recently spoke with someone who's spent more time on a dyno than me working on S2s and he said that what we have here doesn't make any sense to him. The only car that is about right is Mark's, he meant that for all the others (except stock ones) the driveline losses should have been higher and his opinion is that the higher the engine output, the higher the losses.
As I know that person very well and as he is an engineer and he's also been a professional chip tuner since 1990, I'd tend to believe him on this one, although I've expressed the contrary more than once here...
So the point is that something is wrong with the driveline losses at PTS, it's weird because a stock 3B will come out at around 220 and an ABY at 230, but as Doug said earlier, it might read too low past a certain HP level....
IMO it reads too low to a certain extent, simply because of the tiny fans that can't simulate real world driving conditions, but what about it being out of spec past 300 HP????
So, I'd be well tempted to say that we'll soon need to find a more accurate dyno place, one with fans where you can't stand up in front of them at full blow would be really nice...
Ideas anyone???
