Buschur racing question

[oneil201]

well im looking into now getting my manifold ported n coated, and i heard buschur racing does great jobs. but when i contacted a representative they sed they dont coat their intake manifolds? am i under the wrong impression they did or am i crazy?

i think they do exhaust manifolds but there are plenty of other companies that will coat whatever you want. Search around I like triado custom coatings.

Ive only heard of Buschur coating the exhaust manifolds. MAPerformance has some coated intake manifolds for decent prices.

Why would you want to coat an intake manifold? I haven't heard of people doing that. I can see why exhaust manifolds are coated. Coating an exhaust manifold will keep the exhaust stream hotter, maintaining more exhaust gas volume and velocity for quicker spool and exhaust evacuation. Also it keeps the engine bay cooler.

But I'd think the intake manifold should want to sluff off as much heat to keep the intake charge as cool as possible for greater air density. I think intake manifolds are aluminum to remove heat from the plenum faster. Coating it would defeat that purpose.

But if there is a benefit to coating the intake manifold, I'm up for some edumacation.
