Com'on Andrew! You know me better than that.
And if you ready the post again, you notice that I'm basically saying a "baller" makes dumb purchases.

Next week I should be able to test it on a car with our built motor and built head package.

at this point the manifold is restricted by the throttle body.

at this point the manifold is restricted by the throttle body.No you dont.You want speed and velocity without turbulence.Turbulence is a bad thing.In the lower intake manifold,the casting is not so bad since it helps atomize the fuel.

at this point the manifold is restricted by the throttle body.people have made over 1000 whp on a stock throttle body..it's not limiting anything for 99.9% of people

To the OP - I can't wait to see what kind of gains can be made on a high-boost built application. That's where this plenum will really shine.

as soon as i get mine from Sharif ill test it at 25+psi on the intense/powerlab 76S turbo kit(or somethign else
)I cant wait

I know that in a NA situation you want some roughness to create the boundry layer along the sides of the runners/plenum/whatever so that the air can slip through faster as friction is lower between air/air then air/metal surface. In an FI application im not sure.
