Thread: battling heat soak

I went out and bought some exhaust wrap for my downpipe this weekend and put it on when I was doing some other gaskets. My IC piping, which runs between the radiator and DP, already had some heat wrap on it to block out heat but still stayed pretty warm right before the intercooler. Now that the DP is heat wrapped, the hotside piping stays much cooler to the touch just before the intercooler and the rest of the under hood temps seem to have gone down as well.

When I was at AutoZone last, I noticed they sold the foil "radiant" heat wrap for ~$20. I think I may give it a shot on my cold side piping after I invest in a turbo blanket to bring my under hood temps down more.

Here is a pretty good article about battling heat soak:

This should be common sense at this stage in the game.

You bet, main reason I posted it because it had actual dyno numbers to show the difference between hot parts and colder parts .

I already did that test with my cobalt ls. lol
It had about 5k miles on it when I had it dyno'd and i redyno'd at about 22k miles (besides oil changes, i only had replaced the battery). Same shop and dyno.
Only difference is the air outside on the 142whp pull was about 30F cooler.

Have you found what that material is and where to get it?

Here is my goal, get base temperatures, wrap with heat wrap, then drive, pull back the heat wrap and test the temperature. Then do the same with radiant wrap.

This heat shield is supposed to be the stuff with the best results for radiant heat.

edit: now I saw this and maybe it's better. doesn't go around bends as well maybe?

But isnt the heat that comes from the fans blowing thru the radiator, Convection heat?

I'm not saying this to be an elitist or a prick or even poop in this thread, but this is one of the main reasons I love a2w setups and why I will be using one. You don't have to worry about this unless you completely heat soak your water loop somehow.

What about thermal coating your exhaust components? Is that an option? And then utilizing that gold wrap stuff like listed above?
