re vipair input from uk

[broncoupe]

i have carried out back to back tests on bmw m3 in uk,with a gruppe m induction kit the car accelerates quicker through the gears, but if you cruise at 90-105 mph and and go WOT the pick up is just destroyed it is that marked a differance.
We concluded that the factory sealed airbox which is feed air from the front of the radiator and front brake cooling duct was in fact mildly supercharging the air at that speed just my thoughts
