I will still maintain my position that the design quality of the individual components are the key element to performance rather than the boost pressure one is willing to run.
that should be put in the DIY FAQ and pinned.

Im glad he brought that up, Its killing me that FM is doing that. I like their casts for the downpipe and manifold, but thats silicone is destroying me.

I guess they've seen too many evo's doing it? That' just looks like too easy of a piece to get a leak, plus the cooling data Corky posted...

Now, running a single, formed piece of silicone hose like that from the intercooler outlet to the throttlebody might not be a bad idea, but yeah, that's the pic I assumed Corky was referring to.

That's gotta be one expensive mother f'er to replace as well.

its just convience they are using those, It woudlnt be bad but your still losing heat transfer.

If you can get it for cheap, then I could justify it. Corky highlights in the article, and has said so to me personally, that you shouldn't underestimate the amount of heat that can be lost from piping (particularly pipes that are made with the appropriate material). Since cooling the charge is the reason behind an intercooler, my make the process less efficent by using insulating materials.

Because after the intercooler's done its work, you don't want heat from the radiator and engine bay to heat the piping right back up...that's why I said perhaps running an insulating piece of silicone like that "from the intercooler outlet to the throttlebody might not be a bad idea."

I have no hard evidence, but I suspect that an insulated intercooler outlet pipe would be slightly more efficient than an all-metal one. Although, come to think of it, 1/3-to-1/2 the pipe is outside the engine bay anyway, perhaps even getting some more cooling airflow over it...so, it's probably a draw either way...on the intercooler outlet pipe.

If anything there is going to be more heat transfer between the intercooler and radiator than that small pipe from the IC to the TB. Two heat exchangers that close will trasnfer more energy than that pipe with a gigantic air insulation.

Sure, but that's the nature of a FMIC, right? I mean, there's no way for you to insulate the intercooler from the radiator, per se...once airflow stops, things will heat up. Short of a v-mount, there's not much you can do to change this fact.

Let's say using an insulated, silicone piece from intercooler outlet to TB works well enough in not conducting extra heat that it offsets some or all of the transfer from radiator to intercooler...would it not be worth it, then?

In that situation yes assuming flow is the same blah blah blah ya know.

But what Im saying is that the heat transfer from the TB tube is very insignificant compared to the intercooler and radiator heat transfer

When we did the IC temp. testing, the temp. into the throttle inlet was 4 degrees F higher than when it left the intercooler. Insulating this tube would not be a bad idea.

wow im surprised, possible its from the intake manifold? Cuase then the insulating would be a bad thing

Haha you didnt win anything. Im still betting the heat is coming from the intake rather than the radiator.
