Was a different dyno keelaw. Both Dyno Dynamics though surreys RR is a 4wd version.
I would say, when i done the 282 run, that type of map was on for 1 week.(agressive version from Bluefin)
Its been on for well over 6 weeks, and the car has improved since .
There was another car there on the same day ran Identical figures to the same rollers i ran on both occasions and his was with 1bhp of his run.(A stage2 K03 GTi) Red Robin forum user
Id say the rollers were very accurate, and believe the mk6 results, and had a good chat with the mk6's owner.
