Has anyone had any experance with wraping the exaust pipes or turbo charger with the high temp insulation to reduce the heat in the engine bay, is this any good?

As far as I know it works....

My headers,crossover pipe, turbo downpipe are wrapped and the turbine housing is coated with Swain's White Lightning and wrapped over that, in an effort to keep heat down.

I don't have a way to check temps but should be better than stock.

The wrap is less money and works well but at a later time I will spend the extra money and have everything coated with either Swain's or Jet Hot.

Can headers be wrapped while still on the moter in the car?

I'm not sure this would be an issue on a car, but the header wrap will hold any moisture that hits it and rust out your pipes in a matter of months. I had to replace a complete stainless system on a motorcycle once because of this problem. You also have the problem (again, maybe not such an issue on a car) of the wrap possibly comming loose and getting tangled in moving parts - much more hazardous on a bike where the exhaust is directly infront of the rear wheel......

Jet hot coating didn't fair very well either (on a motorcycle again) when left to weather in the elements ~ perhaps under the hood of a car where water is a LOT less likely to hit the hot pipes/turbo it would last longer than 2 years, then again maybe not. The 1 thing I've used that DID perform well, and didn't weather/age was ceramic coating. Both the inside and outside of the pipes were coated and the looked as good at 50k miles as they did when I pulled them out of the box.

I'll second the recommendation for coatings. I've got the turbo pipe wrapped in thermal wrap and the exhaust pipes all coated with ceramic. The ceramic coating is much more effective and it doesn't trap oil or any other fluid that might leak onto it. Jet-hot's chrome like coating is only good for ~1300F....above that and it bubbles and chips off. Make sure you get a true ceramic coating like swain's. Our turbo's run hot....darn hot.

Header wrap is evil. Yes it does hold the heat in, but it also causes the metal to "sweat" or condensate. Which will rust out what ever is wrapped in a short time, because it can't evaporate. I had this on the race car and the header is a complete rusted POS now. I replaced it with a ceramic coated header and it looks great still.

You don't want to wrap aluminized steel exhaust.

If you are running good stainless exhaust components, you should not have a problem with rust and or corrosion from the wrap. Did you know that there is an insulating fiber barrier underneath the factory heat shields on 951 headers? That insulaton will hold moisture in the same as header wrap. When I removed my shields, the pipes were all in great shape. (125,000 miles and a fire)

The only problem I know of with header wrap is the extra heat that is in the pipes. This can brittle them over time and you can get cracks.

Mike - You'll need to remove the heders to get them wrapped correctly.
