FMIC Piping costs

[A//// Guy]

Yea intakes are a whole different story than piping... Piping will absorb more heat because of the larger area of tubing versus just an intake manifold. Especially if you use a phenolic spacer between the manifold to cool things down. I was mainly talking about having aluminum piping near the exhaust. I guess it depends in where you are routing the tubing. I know intakes and IC are made out of aluminum but having super thin (but strong?) piping will heat up pretty quick, compared to other materials.

It will also dissipate the heat quicker as well. So I guess SS or aluminized or mild steel piping does not absorb heat? Hmm, that is interesting. And a phenolic spacer... good boost leak.

Sorry guys, but I am going to have to disagree. Where do you think the heat is dissipating too? Maybe the coolest area around, which would be the air inside the IC pipe? Those all out drag cars the IC pipes are not near the exhaust, like on a DSM and weight is most important on them. A 3000 lb DSM, saving 15 lbs on IC piping isn't going to do squat.

I do agree that there are good and bad points to both sides. The SS is heavier but the Al heat soaks more. Which is better? It is probably pretty damn close between the 2. Very thin SS is probably the best for a DSM.

No boost leak on my spacer, even without longer bolts/studs to compensate for the added thickness. Just use an intake mani gasket on each side of it and you are set. The only boost leaks I had were from a shitty EGR blockoff from ebay and not properly sealing the port for the PCV on my intake manifold.

And yes the spacer works, you could tell after about 10 pulls on the dyno when you felt the intake manifold compared to the IC piping and the piping was warmer. Not that anyone was arguing the effectiveness of the spacer.
