By the way, plastic intakes seem like the way to go for other reasons. Ever
had to deburr a plastic casting? Can you see how a plastic casting could
flow as well out of the box as a modified intake? Make the manifold
shiny-smooth for maximum velocity, that's the ticket. Or at least I think
it is. Other nifty things you can do with plastic is you can optimize the
intake with CFD techniques and then take the dimensions of your optimal
design and prototype it (or the mold for it; its inverse) using
Stereolithography (UV laser and UV-sensitive liquid polymer). Too bad you
can't do the same for exhaust manifolds/headers. Not to mention cylinder
heads.
So what college are you going to? ASU is Arizona State? I'm a Purdue grad.

Composite plastic intake manifolds are being produced in industry right now.
GM makes em for one of their v6s. They claim that they remain cool, weigh
less, and are cheaper to produce since other components can be integrated
into the molds. The last issue of the SAE magazine had an article about
plastic manifolds too, cant remeber the specs off the top of my head though,
i'll check it out.
i wish my cars manifold could keep cervezas cold!
on the note of thermal conductivity, the Summit import catalog is selling a
sort of heat reflecting "sleeve" for cai's. At $50 a pop, its kind of
expensive. wouldnt a low conductive coating on the cai have the same effects
if any for less? How much do these coatings cost? My old battery leaked all
over my PR CAI and im stuck between powder coating and the heat coating the
pipes.
thanks
