Cobra Intake specs

[Fast Orange]

I'll post this here so it doesn't get lost in all the rambeling...

I don't know the HP gain of using a R/S leagle intake, or porting the Cobra but here's how much the Cobra lower chokes a GT40 head. Keep in mind a GT40 head matches a Felpro 1250 pretty good. I don't have my intake off the heads to give exact measurements, and I'm using a lower thats sitting on my shelf.

Felpro 1250 gastket port measures 1.20 X 2.00
Cobra Lower port opening measures 1.00 X 1.70

Does anyone know how much CFM the lowers actually Flow?

I think the cobra's flow 205 cfm

According to the powers of Google, you are correct. BUT. The flow of each port varies greatly. Something on the order of 20cfm lower then the posted 205cfm, IIRC. I know I have the numbers somewhere at home, lemme find them and post them when I am at home.
