Forum Rolling Road day @ Superchips 6th June 2009
JPC:
i can completely understand caz's car being over, the diesels almost always are over by a good 10%
WhiteGTI:
God knows whether this offers a potential explanation, but were the cars that ran later in the day the cars that were achieving silly figures?
E.G. Mine was towards the end of the day, Dom T's was shortly after mine, as was VW Rascals. Caz's was late too.
Dom's ran higher than expected, and VW Rascals stock GTI ran 230hp if I remember correctly?
Although saying that....there was another standard GTI that ran quite early on that got 230hp.
Dunno? :confused: :confused:
markymark:
Mine was second on the dyno and achieved 276 :smiley:
WhiteGTI:
Here is my graph - kindly provided by Jamie!
If anyone can make logical sense of it - to maybe help explain the higher than expected figure then feel free lol!
john_o:
eeek 78bhp loss :surprised: , thats 40% (of the wheel figure) or 28% of the flywheel

and given it was in 5th then it will be a higher figure.
