Interesting...Houston I never even thought about the cranks !
So theoretically if driving style,pipes and cranks are identical the following would be true:
3 port= lots of torque, not the best top end. Best for small tracks?
5 port= good low end,good top end. Good to great on all size tracks?
7 port= poor low end, screamer on top end. Best for big tracks?
Just trying to dumb down the understanding of this.....
