Can you tell me more about you set-up, cubic inch, turbo size hp,ect.. as much info as you are willing to share? thanks

I know there is the idea of loosing velocity with too big of a primary, but has there been any real evidence of this. when using a 1-7/8" primary on a turbo header?

 

My setup is a 408ci motor, twin t70 turbos, not running yet so we don't know the HP.

 

did you buy that front plate or make it?

 

I bought it from Madman, he is a sponsor, they cost under $200.
