**Twin Turbo 67 Dart Project**
Where exactly are you getting your info on intakes??? I am a bit confused on this issue. You will have turbo lag with the A/R size on those turbo's! Considering the size of your cam there too you will have to get above 2500rpms to get into the powerband. So, I am thinking you will not see boost until the same if not over 3000rpm. I assume your ride is for race only purposes?? Running an Auto trans too. Trans-brake??
My car is specifically for street use and drivability is an issue. My idea was to use the Performer RPM so the engine will be able to pull itself off idle until boost is achieved. You will not always be in boost condition so the intake WILL affect lower rpms. I do understand that there is a difference in boosted engines but still gonna have low end issues reguardless with the single plane intake off idle.
