-Yes, I have the OEM heatshield on

-No, I took it off

-No, I took it off but I added my own heatshielding


*Was supposed to be a poll but I messed up. Just post below. I'm talking about the big shield that covers most of the turbo, not the aluminum on the firewall. If you added your own heatshielding, please elaborate

Mines off. Probably should put it back on though.

Took it off in hopes to keep the turbo a little cooler.

I took mine off and couldn't replace due to a larger than stock Turbo, Didn't notice any side effects (until I melted my piston which I doubt is related{still un known cause})

Keep that bitch on for now since I'm still on the itty bitty baby turbo K24. One day I may go bigger, at that point I will do something custom.

Not on my R, but back in the day I took the heat shield off the my 95 Eagle Talon TSi AWD. Took off the exhaust manifold and the O2 housing ones. Started melting stuff, melted the one of the Le Bra straps, cooked the paint on my hood with no hood heat shield, started melting other crap too. After that no more left off heat shields.

If you think about it, keeping the exhaust gases as hot as possible pre turbo makes more power not less. Turbos work not just on the pressure differential, but on the tempature differential as well. If you monitor EGT's pre and post turbo (no one does) you will see the tempature drop in post turbo EGT's.

How much thermal energy does the OEM heat shield keep in the pre turbo EGT's? Probably not much, but every little bit helps.

This is why you see turbo blankets, exhaust manifold blankets, thermal wrap on turbo bits, ceramic coatings, ect. Insulating the rest of the engine bay from these crazy hot temps doesn't hurt either.

Off, added better shielding to the firewall instead. Good way to keep the turbo and manifold temps down.
Did you cover the lines that run above the turbo with anything? Or straight up the firewall?

Mine has been off for years, and i have no issues, i can't stand those things. I refuse to put it back on unless someone can show me massive benefits.

Off since 2004. Makes a good hood defroster in the winter. :)
