well I got arownd to swaping intake manifolds and see what it would do on the dyno. So here are the results.

Both runs at 20 ish psi boost

Red line => my homemade intake manifold with 80mm Q45 tb
Blue line => Edelbrock Victor x with 65mm tb

 

wow thats actually a very impressive outcome. would you mind posting pics of your manifold up, and are you possibly interested in making another.

 

here is one of the plenum

 

nice, Those Q45 tb's are beasts. I've pulled a few, they are pretty popular upgrades for 240 guys.

 

your car continues to impress me. when i get a civic, that is my goal

 

again i ask you are you interested in makin another i have money set aside for these types of things

 

sure pm me and we can talk.

 

WOW that torque difference is CRAZY!

 

i'm working on something similar.. cept its a LS1 73mm TB

got any more pics of your IM? and where'd u get that material for the plenum?
