I was surprised how small the ports are on a stock Roush/VMP lower intake, even on stock heads! Sambandit (Scott M) has ported heads and said he was disapointed with them, until he resently had 1320 Junkie performance port his intake & blower... On the dyno the ported lower dropped boost 1.2 psi, but made big gains on the same pulley.
I think stock motor guys could benifit from the ported lower too. Dropping boost on a smaller pulley, while making more power!
I am looking forward to see what kind of results I get form porting the lower intake. I think I will get more benefits from the intake, than the blower , so that's why I am just doing the intake for now. Maybe in the winter will do the blower too. My car is 90% a street car, but it's fun to go to the track a few times a year, I am only legal to 10.0 but once in a while on a private test day, or a street night see what I can do
It is a shame that no one can ever see the pretty heads RGR did for me
Your going to like the BMR upper, do you have a roll bar or a cage???
