Steve,
He gets to almost max revs in top down the main straight so STFU . Any shorter and he would be hitting the limiter here and that would slow the car down considerably for the overall lap.

You're not talking about a road car, you're talking a full aero-packed track car, the down force / drag at these speeds is MEGA, hence why the accleration slows down in the higher gears. If he adjusts the wing attack, it would be on the limiter in 6th down the back straight, but the lap would probably have ended after the first high speed corner .

Perhaps the 6th gear could have been closer to have shaved 1-2s off the lap , but NOT the final drive .

I always "used" to think you knew stuff .

PS. Wait until the new 425bhp engine is finished (that would have only been the 375bhp one).
