Mileage increase with sp2p

I have one, too. I wonder how two on an Aussie Speed slant 6 tunnel ram would work? lol
with or without a supercharger?
*cackles madly*

all kidding aside, i think they'd probably do okay. tipping into the secondaries would probably be pretty eye opening. but i imagine around town a combo like that would have pretty good manners and a lot of throttle feedback.

i ran one on a wheezy 318 2V motor that i snapped one of those 2 into 4 a-dapt-or-plates on and it was more fun than it had any right to be.
