Well as I mentioned in another thread I want to do something different induction-wise for...well, the hell of it.

To do so will mean building my own intake manifold. Now I have contacts who can weld steel, alloy and stainless. Heck, this guy can weld a coke can.

But I want to go to him with a set of plans and to do that I need an idea on what I'm doing. I've started reading on manifold design but I was wondering if anyone here could assist in the technical aspects of runner size and plenum size. I'm aiming for a good street engine with torque...

Any suggestions?
