i thought it was the other way around, shorter runners = higher revs and more power up top. Longer runners = More air velocity and more torque.

long pipes = higher torque (higher intake velocity)
short fat pipes = higher possible bhp (less restriction)
long fat pipes = best of both... on an engine big enough to pull it off anyway
The sheet-alloy top to the manifold, just gives the airflow a nice easy path to the outer runners. Not good for a "street" car, but perfectly fine for a drag car
Fave bit of this car: driver gets an all-out race seat, yet the passenger gets lumped with something that looks like it was pulled from a scrappy ;D

Real nice .....but ....the rear end chassis is so narrow surely there will be loads of articulation in that set up.....might be scary at 200mph

Longer runners = More air velocity and more torque. your right, short runners move the torque up the rev range, which then makes more power. pushrod operated dump truck sized american tanks need there torque low down for drag racing. and the pushrods would explode if reved to the limits of the rest of the engine. harsh but true  |
