Default Anybody know about these?



They were supposedly made by Arizona Speed. I've never seen these kind before. Any better or worse than the typical SLP, AS&M, etc.?

I see you're watching the same auction I am.:D

I checked AS&Ms website and they do look like their semi-siamesed runners. I don't have any performance numbers on them, but I've heard nothing but good things about them.

BTW, can anybody determine from the pic if the runners are the early type with the cold start or the later style?

Yup, they're cold-start. That's what that hole is on the bottom.
Those look good, can I get in on the auction too? :D

I figured someone else on here was watching the same auction but just incase that is why I posted the pic and not the URL to the auction. :D

I've never seen runners that are siamesed half way down like this but I am thinking it is a good idea.

Looks cool. Definitely different than my SLP runners which are only siamesed in about 1" on both ends. I don't know anything about those particular runners but it seems like siamesing the runners near the plenum basically adds to the plenum volume and reduces runner length. Sounds like just the thing a stock TPI intake setup needs so the car can rev past 4800 rpm. Good luck!

that's the best TPI runner on the market right now. top end is improved over the standard design. things cost a fortuine new, if you have a big base and spend sometime porting your plenum you will have one nasty TPI setup.
