it makes sense..... if u put an intake on a 240..... and its supposed to net (just for arguments sake) 8 horsepower at the crank.... once it reaches the wheels its gonna be like 4 horsepower.... or less..... on a fwd drive car if its supposed to net 8 horsepower at the crank.... it will get about 6 horsepower once it reaches the wheels because it doesnt have to go through a drive shaft to get there.... makes total sense to me.
