There are two variables that control port timing.

1) the shape & position of the port.

2) the opening & closing edge of the rotor.

Of course flow is a seperate issue.



This motor (with a stock turbo & IC) made 233 net HP on the G-tech, but the real fun was the broad mid-band torque.

Have you tried the beveled rotors on a N/A application? Results if any?

thats pretty cool, from pics i have seen in the past, seems like most people that modify their rotors only open the closing side of the rotor.



can you please elaborate on why you chose to do this aside for the obvious reasons of extending the port timings.



how does the car feel? and how does it idle? like a car with oversized streetports? how does the idle compare from street porting to street porting in addition to the bevelling
