I can't remember off the top of my head but you should get 3 swoosh's of 80+ psi in each housing.

If you looking into power on these cars the best bang for buck power gains are with a free flow header,cat and exhaust system.Then add a good carb to it and you be smoking some pesky little hondas

Yea exhaust is important. I kinda wonder if the stock exhaust is holding this one back. Ran it with just the ex manifold today. WOW!! Id race just to listen to that!
