Turbo wrap vs. factory heat shield

[ANDYS87]

I was looking through the Summit catalog and noticed they sell heat wraps for turbos. It looks like an aluminized insulation that you wrap over the exhaust elbow. Does anyone use this? I was wondering if it lowers underhood temps better than the factory heat shield? Maybe improves spool-up too, since it keeps the heat in the exhaust portion of the turbo???Just curious...might buy.

My turbo was Jet-Hot coated by manufacturer...got it from Cotton's Performance in Mass. This coating is best applied before ever using the turbo, IMHO.

The factory (GM) heat shield is there to protect the paint on the hood and to keep everyone from actually touching the hot part of the turbo. It doesn't appear to keep the heat in the turbo.

The aluminized cloth heat shield the Summit and others sell that covers the exhaust side of the turbo should do a good job of keeping the heat in the turbo housing.

I bought a turbo jacket? not sure what the name is but I seen the same one on ebay it has clips and is insulated and clips to the turbo hot side with metal clips seems to work nice.....alot neater and you can remove later on and use on another car or sell it....I dont have pics but if I see the part on ebay I will post the linky

Yes a blanket/insulation for your turbo and pre-turbo exhaust will help with spool up and reduces underhood temps.

As mentioned, the stock turbo shield is only to keep you from burning yourself and to keep the hood from getting too hot. It has no performance benefits.

Remove your stock turbo sheild and drop 2 pounds off the nose of the car.
Then replace it with header wrap and a turbo blanket. Less weight, less heat, and more power, yay.

One word of caution is that the header wrap on stock headers is not the best idea from my experience. The extra heat held in the headers is a killer on the poor quality stainless they used to make the headers out of. I ended up with cracks where the metal flakes up in sheets. For this reason i removed the header wrap, but spool up is slower.
