removing heat shield

[IHeartTurbo]

i have seen quite a few engine pics with the heat shield over the exhaust manifold removed. i was just wondering what benefit this could have?

There are no benefits of removing the heat shield. Keep it on.

then why do people do it?

Leave it on, ... there is no benefit of it being off aside from the 1lb weight savings haha.

They're either running a different cast/tubular manifold, an external wastegate that they tapped off the stock manifold, the shield rusted off, or they're just dumb and think that by removing half a pound of metal will make their car gain mad tyte horsepower.

Heat = Enemy. That's why there's header wrap, and all those crazy things to keep exhaust heat as closed into the car as possible.

I dunno, you see anything here that looks like it might bother a plastic fan?

Geez, NICE pic of a glowing red header & turbo! That image is every reason why people should not remove the heatshield. I've thought about getting header wrap to minimize the heat emitting from the headers.

Anyone do this before?

I cant believe how fking hot the underhood temps are on a DSM, like the fires of hell!

Go check out a rotary some time.

That's my excuse I actually think it just got lost along the way when I had to swap engines.

But yes, do keep it on. I've been halfheartedly looking around for one, cause my underhood temps suck.

I took the lower one off when I did my Big16G install and damn...two days afterwards I had no fan in front off the turbo..** It was just a piece of melted plastic hanign there:-( Now I made my own to protect the fan and radiator but I havent found a new blade for the fan yet...

To sum it up: Keep it on! ;-)

I took mine off and haven't noticed a difference in under-hood temps or noticed anything melting even on hot days. Of course I also coated my manifold, exhaust housing and O2 housing with high temp paint that has ceramic in it. Color burned off and left ceramic behind. See gallery

Hey Enigma Man, I have the upper shield off mine laying in my garage collecting dust. Just make me an offer. If you want I can sandblast it and paint it with high-temp paint I used on my exhaust (I'll PM you list colors if you're interested)
