So I am piecing together the last parts needed to do my 16g install. And I decided to try my best to keep heat away from the turbo.

I'm planning on fabricating a custom turbo heatshield, and will wrap part of the downpipe and maybe the uppipe with fiberglass header wrap. I am also toying with the idea of buying some sort of an adhesive backed heat barrier like you see here:

I'm thinking of just covering both end tanks and sides of the intercooler in this stuff, but I'm not sure if that will be effective. Maybe I should just cover the cold side of the intercooler in this stuff?

What other precautions could be taken to keep heat from the intercooler? Lets brainstorm people!

That adhesive barrier says it's for radiant heat (doesn't say anything about convection or conduction). So, if you stick it to your IC or IC piping, it'll still get heated up by hot air just like always.

All your other ideas sound good. Also, IC spray is probably the most effective thing.

Yeah, but at least it will be deflecting the heat from other sources, there's nothing I can do about the hot air coming from the turbo. (well, aside form getting a different turbo)

I'm thinking about an I/C sprayer to. I wonder if I could modify the windshield sprayer system to spray on the intercooler instead...

Get a wagon washer bottle with the 2 pumps...so you retain your windshield washer and then also have IC spray

good idea there nick. I might just try that.

I've been trying to spend some time in the trenches of the heat battle lately myself.

For my vf12 install I applied some of the super-pimp GOLD mylar around several areas adjacent to the turbo. It is expensive, $40 for 2 linear feet, but I still have a bit left over. Here is what I covered/adhered it to:

1) Charge pipe from turbo to IC (where is rides next to the heat sheild - I have custom AL intake plumbing)
2) The whole inside of the stock heat sheild
3) the side of the resonator that hangs over the turbo (least effective I'm sure)

I'm sure that it all has a minimal effect, but I certainly can't hurt - and again, I think it looks rad (even though most people won't even see it in there unless I point it out).

It does seem to have made the outside of the heatsheild cooler to the touch...
And yes, it blocks radiant heat, which is NOT the sole mechanism for heat transfer here, but it helps. And it's very hard to put an effective insulator in some of these places. I do, however, have some of the mylar coated fiber insulation wrapped around my A/W IC feed line that travels right over the turbo - I may do more of that over the driver side run of the A/W coolant line too.

I'll be wrapping the upper portion if the downpipe as well some day, but it's a shame to cover up the beauty that IS the CES divorced DP maybe I'll cutout the "CES" plate that is right by the flange...

I was going to save some of these pics for a write-up I was going to do on the VF12 (once I can get to the track for some #'s), but anyway- here are some shots of the GOLD -





My son, Ian. He thinks gold is sweeeeeeet


More of a top, overall, view.


I got the material from enjukuracing.com if you're interested. It is much more effective than the silver stuff from Summit or the like, from the literature anyhow
