ok here some thing i need to know and soon im about to start building a fuel injected inlet manifold do i make it out of stainless or alloy i know alloy gets rid of the heat quicker but stainless would be easyer lol
any thoughts from those in the know

double post .....

i think ur mixed up alloy is much easier, easier to cut, drill, maybe a bit harder to weld but not that hard if ur measurements and cuts are accurate..... only problem with alloy is u can't weld mild steel to it

yeah but i was thinking if i got a stainless flange plate cut the same as a gasket it could be a one peice manifold that would make it easyer for me to build aswell

I was thinking of a 1 piece flange too, for a turbo project, but the problem seems to be this: Feel how hot the exhaust manifold gets after driving... the air gap between the two keeps the intake manifold from getting super hot.

Maybe i'm wrong, I'd love to be wrong about this.

I think doing it as one piece would be bad for the intake charge temperature and could possibly get hot enough to set off the fuel in the runners.

welli was thinking of making it all one peice then after it was all welded then cutting the inlet off to seperate the pair as in the standard setup the only reason for making it one peice to start with was ease of building it

dont anyone have any ideas ?

BUMP!!!

Me being in the game, S/Steel is ezy. Can do Alloy to but S/Steel looks better

Use alloy if you can. Just try and keep it and away from the exhaust.
Alloy heats faster, but it also cools faster.

Steel heats slower, and cools slower. With the intake charge rushing in, Alloy cools down fairly fast.

What does the factory use? Alloy! For weight, and for the heat capacity properties.
