I have been looking to purchase a heat wrap for the stock turbo but cannot find a direct fit product on the market. Not sure if anyone is using one or if it is even worth the time/money to do in on the stock setup. I'm using GM's stage one upgrade and going to buy a zzp catted down pipe. I saw DEI makes custom heat wraps for t3/t4 turbo's and has a generic kit as well. Is the t3 close to the same size as our stock k04?

Thanks

 

dont bother

 

thanks for your opinion. Anyone else?

 

I'd rather have a hood that funnels air to cool the turbo . I don't think heat wrap would benefit much

 

There is a guy near me on hondatech.com who tested different levels of beat shielding from turbo blanket to heat wrap on the downpipe to heat reflective wrap on charge piping and the intake. Results were they work very well. He measured heat in a few different places and used the same constants throughout the test to give real results. His underhood temps went down a huge amount. I'll try and link it if i can find it

 

Going to run one for the 6262 i am putting on tomorrow. There is a reason they are produced.

Thanks ATLsilverSS. I appreciate everyone's input so far

 

I have one on my S256. To further let the heat escaped from there, I'd removed the rubber seal in the back of the hood and cut slots on the black plastic where the rubber seal sits.. I carry the rubber piece in the trunk in case I have to put it back in when rain heavily. At a stop, I can see the heat rises out from there. Plus I got couple 5.5" fans installed under the hood just for the hell of it.

 

I always thought that the purpose of the heat blanket wasn't so much for under hood temps, though that certainly us an added bonus, but rather to keep the heat in the turbo and make it more efficient.

 

Really its both. Yes keeping the thermal energy contained will make the turbo more efficient and by containing the heat keeps engine bay temps down. That will help with several things in itself.

The only downside i have ever really heard of is the blanket or heat wrap getting oil on it if a leak occurs and a fire occurred resulting in a burned up car. That is the only negative i have heard of. And ive heard it happening multiple times not just once

 

anyone know if the k04 turbo is the same size or hame similar oil line layout as a T3 or T4

 

Exactly why I haven't thought of doing it. I've had turbos explode on Caterpillars twice, neither resulted in a fire fortunately. Kind of makes me gunshy so to speak.

Sorry, I don't but here's a free bump for your question.

 

thanks for the bump, but I found several pics of the turbos and think I can make something work.

 

If any part of where the turbo leaks onto is greater than the auto ignition point it will light on fire (most oils around 230-250C), but I can see where an oil leak onto the heat wrap would allow it to reach the auto ignition temp.

I've been tempted to wrap the dp but it hasnt gone any further than tempted

 

I wish I had more free time to experiment with stuff like this. We could all benefit from it, but no one has done much like this.

 

The stock turbo is covered with heat shields which direct the heat away from the engine bay towards the downpipe area. It’s is plenty sufficient for our application.

Heat wrap and blankets become more critical for cars that weren’t initially meant to house a turbocharger much like the Civic used as an example in the link given above because some of the components surrounding the turbo may be sensitive to the additional heat.

 

Go do a few pulls then pull over and feel under the hood, the stock heat shields protect other parts from heat damage. heat wrap is to keep heat energy contained inside of the exhaust or turbo for greater efficiency

 

turbine inlet gas temperature is the only thing which will affect turbo efficiency, having a blanket on the actual housing will not affect inlet temperature. Wrapping a manifold to increase turbine inlet temps would however help, but do a little thermodynamics and you'll realize that there is other fish to fry.

 

Def not going to be a huge improvement I'll agree, but lower unhood temps can help. Wrapping the turbine will decrease the loss through the housing, if its significant idk, could it cause heat related damage maybe.

 

I'm just saying this is not a way to improve turbine efficiency.

 

This is a 100% correct response. That's the entirety of a turbo blankets job.

 

The best heat shields are multi-layer (reflective inner layer, low conductance inner layer [fiberglass/ceramic/mica/etc], metal outer layer) and are mainly used to protect surrounding components from getting damaged from the heat.

Heat wraps/braids work but compared to multi-layer perform much worse. Their benefit is that you can really form fit them. With them you will be holding in more heat because it's harder to escape...will it make a noticeable difference in performance? I doubt it but to know for sure we need before/after data of pre-turbine gas temp and pressure at the least.
