Does anyone know where is selling T-78 Heatshield, or how to make one ??

Thx

and it fits perfect on the t78 too!

 

Third for the gotham blanket, I had it on my t-78.

 

how do you think its going to fit on the r85 turbine housing? might be a little loose right?

 

I am actually looking for a heatshield, but thanks for the input.

 

The t78 kit comes with this gay flat piece of metal that you're supposed to put between it and the engine. It does little for heat containment. The blanket will help worlds in helping reduce underhood temps versus a shield. But hey, its your setup, do it however you'd like.

 

I heard that heat shields are good for reducing radiant heat however doesn't block the heat in causing premature failure on the chra do to the exsessive blocked in heat. Of course it's worse on oil cooled only engines but still bad on oil and water cooled.

 

Will this blanket fit on my GT42R?

 

This one does!

so now this turns into a bad modification

 

When it comes to this, how much mileage do most of us single turbo guys get on our single turbos before a seal gets puked out into the turbo causing us to have to rebuild the engine and turbo anyways?
I'll take my chances.

 

Exactly. I have never seen it cause a direct turbo failure, but the dramatic drop in underhood temps is well worth it. Think about all the harnesses, hoses, etc that suffer from the radiant heat.

 

Yes, better to replace a t-78 after 80k miles of hard use, than replace an engine ever 20k due to heat transfer issues (coolant/oil/intake air).

When I had my blanket on, exhaust fully wrapped, vented hood, fmic and fan mod, I never saw coolant temps above 92*C while moving, even climbing the mountains in deals gap runs. I could go for a HARD run and pop the hood and literally touch the turbo blanket for a couple of seconds.

 

ok so you guys say to do this even with an oil cooled chra? Or would a heat shield be better?

 

You have 2 options.

1) run the turbo "open" with little or no heat confinement, let the radiant heat out into the engine bay where it soaks everything and causes the slow death of the engine.

2) contain all the heat via blankets/wrap and keep the heat in the exhaust, not the engine bay...harder on the turbo over a long period of time, much better for the rest of the engine bay.

 

gracie! makes sence to me. Guess I'll go with a turbo blanket instead of heat shield then. Guess i'd rather spend a few hundred on a turbo rebuild then a few k on an engine rebuild and new microtech wiring.
