i think i'm the only person working on it (quite slowly at that)
i have a prototype that ive already run, and now im going to get something machined adn make the second protype that should more closely resemble the finished product.
i will then dyno test it against the only other intake manifold i can find. its made by
http://www.xcessivemotorsports.com
however, this manifold is for turbo, so while its runner length os good for higher rpm power, its plenum volume is too large to make peak torque at a decent rpm. plus its 500 damn dollars
i wont have anything available for sale until this winter, but it'll run about 250 dollars.
so, youre best bet is to either buy the xcessive unti and weld in a piece of sheet to make the plenum volume smaller, or make your own. however, if you dont know what youre doing, you are gonna have one hell of a time designing something that will give you the characteristics you want
