OOps I made a math error,intake port open time in duration is .00021 seconds. Increasing intake duration to 185 degrees =.00023 of a second actually increases the port open time by 9%,-a possible 9% power increase. I will take that anytime,in fact I will do the mods needed even for a 1 or 2 percent increase,it all adds up quickly.
