I am debating on whether to put a turbo blanket on my turbo. I currently have a GT3582R. I have been reading a lot about the benefits of lower temps and theoretically faster spool, but want to get opinions on the negative of too much heat for the housing. I was also going to wrap the downpipe. I have a pic of the engine bay attached.

Does anyone think the blanket will cause pre-mature failure of the turbo ?

 

I doubt it, turbo's are designed to sustain pretty high temps.

But who knows, I doubt anyone will have any proof of this. It will be theory. I ceramic coated exhaust housing and mani for this reason.

 

I run a turbo blanket on my race car (is300 + 2jzgte) and have been asked to remove it by my turbo technician. They hold in a **** load of heat which is a plus but after an extended period of time they can warp the exhaust housing/flange. I have been through 2 exhaust housings because of this.

I know this is on a race car and it would happen at a quicker rate than a road car but still, something to think about in the long run.

 

We carry and sell the best turbo blanket on the market. We actually include the blanket in our EVOX tubular header kit as it's fairly important on the EVOX with the placement of the turbo and the heat.

 

I've managed to use the DEI T3 Titanium series turbo blanket with a few modifications on the GT30 and it defintiely seems to help control heat. While the turbo itself might be really hot I found that as long as you avoid getting oil on the blanket they hold up really well.

 

Thanks for the replies. This car is daily driven and only sees a road course 5 days a year at most and they're just open track days nothing competitive. I do plan on building the head and block later and pushing 35-40psi after I put more miles on my stock block. I guess I'll take a chance and get a blanket.

 

Just curious want size turbo(s) were you running and were they oil and water cooled ?

 

i would not do it, by law of thermodynamic heat has to escape in some way for the turbo to be efficient, retining heat with a blanket will cause premature failure, and crackin of the hot side.

 

Here is the best blanket available and what we run/sell and include in our EVOX kits:

This is on my HTA3586 on my RS, has been on it since the first blanket was release as we did some testing for DEI. It's held up great, fitment is excellent, like a glove actually.

It will also fit the stock EVO turbine housings and I ran one on Project White.

 

It was a Turbonetics T66 which was water cooled. That was the one that did 2 exhaust housings.

Now i believe it is a Borg Warner S300 with a whole load of porting done on it. Im a torque junkie

 

I have to agree with this. I've seen some brand new non 'ebay' turbos that were completely cooked on the inside after being used for very few miles. I just think the consequences outweigh the benefits.

I thinking about pulling the trigger on these...

would these work on the FP reds?

 

I'm putting the DEI on my BBX. I have the other components ceramic coated but without the regular exhaust manifold shield I figure I should do what I can for heat management.

 

Well I have a Garret GT35R that is water and oil cooled. I plan on upgrading the radiator as well. I work for Honeywell so I have e-mail access to the engineers at Garret and will try to get their thoughts. I am willing to take the risk as heat control is more important to me than the replacement/repair of the turbo.

 

I did notice a slight increase of heat load on the cooling system where temps seem to hover at 185*F instead of the typical 175*F area. Basically just enough to keep the temp into the middle section of the dash cooling gauge. After upgrading to the Mishimoto radiator it's now back down to the 175*F at cruise and spirited driving so keeping that center section cooler is probably enough to counter the blanket and that is where the critical turbo parts are.
