Remember it is the same amount of exhaust running through the pipe. The only difference seems tom me to be the internal flow friction.

Cuz swapping a fully dressed wet 500?lbs 603 into a light sporty car (1985 bmw 3series) will destroy the original handling characteristics. So a rearmount turbo would be a compromize between turbolag and handling.

Anybody know the distance between the cylinders on 60x`s?
