Any word on this? A new manifold costs around that, and if I can get 50 hp, and some torque id definitely buy it. Everyone says oh buy something cheaper, well for a quality set of headers thats a few hundred atleast! so why not something that probably gives you more, than when you do get headers you have like 100 hp just from two mods! Way to go. Id like to see some pictures or something would be great!
So is the airflow from both throttle bodies still funneled through the single opening for the stock throttle body? Or are you opening up a second hole in the top of the manifold? It sounded like you are mounting an adapter plate on top of the manifold to which you'd bolt two throttle bodies (or more), but the airflow still flows through the single opening. But that can't be right. Got pics?
the top of the manifold is milled down to expose all of the runners and the are in turn shortened and modified for maximum air flow.
then a new top plate is machined to accept mutiple throttle bodies. i'll try and gets some pics up here.
