I think a trip to motorscopes rolling road pays dividends, at least you can walk away with a smile on your face
....If your point is that going on JKM's DD rollers doesn't pay dividends and you don't walk away smiling, you ought to think again. As has been said countless times and is appreciated by most drivers, it's all about driveability and the plotted curves - Not all about willy waving the highest bhp numbers. It's all relative and a rolling-road session is an opportunity to health-check your car. Several folks were very glad that JKM were able to identify and solve minor problems on their cars and will have driven away smiling.
I agree with Robin it is how the drives more than the RR figures but I think its bad that they can vary so much.
On AMD's RR in June 2010 at a Seat RR day my car at stage 1 with panel filter it was 257 bhp and 274 lb/ft of torque @ 3200 rpm. Others from this forum were there and their results were roughly what they were expecting.
In August 2010 at stage 2 with TBE exhaust and panel filter my car was 272 bhp and 302 lb/ft of torque @ 3900 rpm.
At JKM on Saturday it was back down to 252 bhp and 270 lb/ft of torque.
Does my car have a problem which is why the power is down? It has been away having some bodywork repairs or is it that the AMD results at stage 2 are totally unrealistic?
I am very confused. Could AMD massage their results to suit that much? The car felt so much better after stage 2 that I cannot believe there was not a good power increase.
I have no problem with the quality of the maps but the results don't add up.
