I'm starting to think of fabbing a new Intake Manifold and wondering what is better.

I know Short Runner is good for top end (right?) and Long Runners are good for bottem end(i think).

If I'm going to be usings a .60/.63 on a Cammed and P&P DOHC ZC at about 18psi after my build up, which style am I going to benifit from most?

you are probably going to want a larger plenum for boost. that means shorter runners i'd think.

make sure you post some design ideas before you make it josh!

Oh it will definitely be modeled in Inventoror Solidworks and analyzed first, if I have time!!!

Plus Aaron, I'll probably call on you for a throttle body flange and so forth.

maybe pick up an IM off a factory turbo'd car (IE: DSM :P) and see how it's designed to give you some ideas....

the thing that im unsure of most would be how you would get vacuum ports and whatnot mounted...

Ah you can do anything from welding in little tubes to tapping in some brass fittings.

I'm most likely going to take a honda Factory IM, cut it right behind the injector bungs and mounts, Port that out and tapper it nicely to the head, the make it off of there. I don't have enough experience yet with making things like that and I want everything to still fit together nicely..

Box pleunm is your friend plus it will be the easiest to cut and set up.
