as said, start your own thread!!

that's arguable because I'd think that you have max. intercooler efficiency with a longer hotside (aka more heat loss) and a shorter coldside (aka less heat gain).

That's arguable as a longer hot side pipe on the hot side would have more exposure to engine bay heat for soak. Though a longer hot side pipe that left the engine bay asap would have less opportunity for heating up. My only point is that without numbers, or before/after any claims are speculation and merely for conjecture.

Pipefather is right on the money. Heat is "injected" at the compressor wheel. However the transit times at WOT are so short that the differences seen are minimal.

m2, didn't you read corky's comments, paragraph 5:

But I do agree with your last statement somewhat, once I get my data acquisition system i expect to have some data on this.

This is speculation with out proof. Where are his numbers?

Absolutely. There is a lot of "fact" thrown around that has no testing done. Just because it SHOULD be better doesn't mean that it will.

You didnt really click the link I posted did you. Anybody who isnt blind can see the numbers quite plainly.

I read it. I must say I'm amazed that the underhood temps were only 112f on a 95f day. It just seems impossible considering my race car interior measured similarly at a July race at CMS in a showroom stock Miata- with both windows down. I actually had my shoe heel melt on the trans tunnel in the foot well with our NB race car. And then to think that the headers internal gases are running ~1350f pre turbine at cruise, and higher under boost. Is it not incredible that the header is really retaining that much heat?

I did when this same discussion came up in the spring.

I should have been more specific, where are his numbers for an insulated pipe (ala FM)? He states clearly that it is better, show me the numbers that prove it. Oh wait, it wasn't tested. Speculation and mud slinging.

Is it better? Probably? Does it matter when you have an I/C in the picture, most likely not.

holy ****. How did you attach that splitter?

ummmmm....do I see an F1 or CART something or other with Bennetton in the garage?

Yep, that's a Bennetton F1 car...taking it out next week for testing

Thought I had posted a dimensional analysis arguement here about why the pipe length is of little consequence, but don't see it here.
In a nutshell the transit time of the intake air to quick to make any heat transfer from the small amount of tube surface inconsequential, other wise, why have an intercooler, just bend up a bunch of pipe! Just break the equation down into thermal conductivity of the air and pipe material, the surface area where transfer takes place, and after cancelling like terms etc, the equation simplifies to units of heat per unit time. Since the time is so short, and the surface area so small (relative to an Intercooler), the units of heat transferred turn out to be miniscule.
