If the heat wasn't in the heat shield, where would it be? Transferred to your alternator, hood, head or power steering pump. Do you want it there instead?

The air gap between the shield and the exhaust manifold is also an insulator. That why it only touches at 3 points?

I'd rather have a heat shield than a turbo blanket. Right now after all this discussion, I think the only reason I'd run a turbo blanket is so that it could sleep cozy at night, and maybe when I'm at Tim Hortons at night I'll have something to lean against to look cool in front of all the ricers

Give it some time, my theory suggests all your manifolds will warp and crack from excessive heat over time

Your theory is probably right. The guys at Road race, and PTP and turbo performance products are all a bunch of quacks.

FACT: These blankets will shorten the life of your manifold. Dare i say it Reza is right. Heat kills.

FACT: These blankets will increase the life of components around them.

FACT: OEM's do not use blankets because they do not pass longevity guideline that they have in place for there product. They don't want to deal with deteriorating blankets that end up making weird smells in the cabin. No manufacturer wants to add that to deal with. Heat shields are the compromise.

FACT: Heat in the right places translates to added power

Well if you say they are quacks, I'm gonna have to believe you.
That's why I only run FP products, and oddly enough they don't sell any That's soo weird!

i'm too lazy to type everything out (plus i should be working lol) but Reza stop by the shop i'll buy you a coffee and i'll explain the entire theory. I'll need a scientific calculator and will clear the white board.

FACT: turning your boost controller one more click will give you more power than adding a blanket. But what do you when you run out of clicks?

FACT: There are other form of benchmarking a cars ability then a quarter mile time

Heat may kill, I agree. One thing Reza may not know that is that rapid different temperature heat cycles kill more! Letting your hot manifold cool slower with a blanket is better than having it cool quickly without one.

Warping? I'll give you that, more heat will warp metal, but i believe the cracking wont be caused by over heating, IMO thats caused by thermal shock from cooling too quickly.


Long story short, I just feel the pros out weigh the cons........ ten fold.

Personally, I'm more worried about my FP manifold and turbine housing getting damaged than any other benefits of this. I guess we all have different goals here. I got over 80,000 km on my turbo and manifold, and they both look as good as new. I just don't think that would have been the case if I had a blanket on them for that amount of time.

Hey look at the Brightside! Maybe you guys might get your SS ARP turbo bolts heat welded into the turbo exhaust housing nicely with this blanket, LOLz

Since both of you two will be racing your cars around a track, I do think this will be beneficial to you. You probably will burn your rad fans and CF hoods without it

We need a soap opera called "As the Turbo Spools"
other then the bickering there are many valid points being raised from both sides of this issue.
Lots for people to think about and lots of reasons for people to either buy or not

I'm looking into this to keep the heat down during extended runs. Maybe not heating the engine bay 10 seconds at a time.

I am looking for a evo3 manifold blanket and a 16g blanket. Also going to wrap my down pipe with exhaust wrap and coolant pipe in foil insulator to keep the heat out.

The wrx turbo blanket fits the dsm 16g properly? or is it baggy? our o2 housing is way different i thought.

My turbo bolts are OEM, Where the frack did that come from?

Im going to keep a close eye on the condition of my turbo setup after this conversation and report back. Im also going to dig up more results on the interweb just for piece of mind.

Im not saying your not right, but Im not agreeing with you either.

Oh sorry my bad, I just thought you did everything Mike did, or Mike did everything you did. Brightside bros !

You couldnt be more wrong, we conflict on many things about building our cars FYI

I'd say our cars are almost complete opposite

1g vs. 2g. 6-bolt vs 7-bolt, stroker vs 2.0 but we both have CF hoods.

Wait till we ceramic coat our manifolds AND put a blanket on them! They'll be wet noodle warped!

i'm looking for the emoticon of the smiley face with a tub of popcorn infront of him....


popcorn anyone??

Realize guys that were all friends and Reza stops by the shop once a month and shoots the sh$t with us. It all in good fun.

Back to the ARP catalogue i go to see if i can get 12pt hardware for my valve cover

My FP mani has been ceramic coated since new (first the FP silver coating, then Swaintech). I origionally also ran a JM Fab headshied that was ceramic coated & had heat tape on the underside as well. I have since switched to the blanket in this thread. I've had my FP mani for years (probably one of the first on this board to get one). Last time I checked, zero cracks.

I ran my FP 3052 with a blanket for years, zero issues. Now running the DSM82 HTA with a blanket.

Sure they trap the heat in, which isn't necessarly a bad thing as far as performance goes but I would guess it may make the chance of cracking greater. With that being said, if you buy a good, properly designed component to start with, cracking probably won't be an issue.


Personally I like the cooler under hood temps & reduction in coolent temps. The parts I run are designed to take the abuse & I choose to run excellent oil. For me the benefits out weigh the possible issues, for others they may not.....

+1 , we go back a long ways, Mike knows how I like to criticize everything. We're all friends here folks

Theres nothing I love more than arguing with Reza. Once in a while I hit a sensitive spot. He tickles easily Spice of life

this is where I ask my gf who has the remote "is there anything else on tv?" hahahah

I don't blame you Mike, at the end of the day these turbo blankets are just another one of those ghey DSM things, like Rob and Mike

Not quite as gay as having an automatic evo wanna be.

Lol good one!
but check again, it's not an auto. It actually has two clutches and no torque converter. Of course you wouldn't know since you don't own one

It AUTOMATICALLY controls the clutch

When something does something automatically i call it an automatic? What do you call it?

Here Mike, enjoy the read:
http://en.wikipedia.org/wiki/Twin_Clutch_SST

There is a reason they call it a Twin Clutch SST transmission. What are you Rob's girlfriend?
You two should petition to Mitsubishi, not me

TomAto, TOMaTO lol

Hey it's passed 5pm, don't you have a go bum frack Mike at Brightside tonight?
I think he's already on his way

Alright lads, hug it out already.

Reza's 1G, his ability to build and tune are pretty godly tbh

One question about this though, increasing the heat in the turbo / manifold, would it not cause the intake temperatures to raise / be higher than usual? Maybe even heat soak faster / longer?

I think it actually reduces heat transfer from hot to cold side.

Dont feed the animals. His head is gonna explode from ego overdose

Guys, the word Godly shouldn't even be used here. Ten second DSM's are still slow as frack IMO. I don't even consider mines to be fast at all anymore.

Everything here is ALL theory, except for the fact that these turbo blankets keep your underhood temps lower, which never seemed to affect me as much in my DSM life.

Sorry Rob, but NOTHING here ever boosts my ego This is the Rob C era. Everyone please swing off of his nuts.

C'mon, don't you got any more pics of powder coated machined sh!t to put up?

This has made my morning reading all these "cheap shots" back and forth! You guys shure are entertaining.
Thanks

shut the frack up Reza, your car is fast

haha That was a good morning read..

Maybe I am out to lunch, but would you not want your turbo to be able to dissipate the heat!?

Not bundle it all up inside?

Darren, have you ever done a comparison with and without the blanket?

Well the theory is that bundling up all that heat in the exhaust housing will cause the gases to expand quicker, thus making your turbo spool faster. I could not find any real proof or tests on this though.

I agree with you Mike. I would rather have my turbo dissipate the heat rather than keep it in. Other things could also make your turbo spool quicker, like having a pressure regulator connected to the top port of your wastegate, rather than a ball and spring on the side port. Some things actually look great on paper, but in reality you may not even notice the difference at all.

Mike, no didn't do any "real" testing but without a doubt they will definitly reduce under hood temps. Before the blankets, pop the hood after my ~45min drive home from work & you'd get a good blast of hot air. Putting your hand close to the mani or turbine housing would probably result in a burn if you held it there. After the blankets that blast of air was much cooler & you could hold your hand within a few inches of the mani or turbine housing, no problem. Could even touch them if you wanted.

In general, coolent temps seem to drop a few deg as well.

As Rza said, keeping the heat in, is supposed to be better for the turbo but in the real world, doubt it makes much difference one way or the other (well atleast not for a "typical" setup).

My thinking is heat kills things, there's alot of stuff under the hood that can have its life shortened from heat, so I'd rather protect it. Up to this point haven't had any issues using the blankets.

Edit: Also haven't made up another heatshield to isolate my intake filter yet after the switch to SD, again, inlet temps dropped a few deg after the blankets as well.

I never cared much for blankets, but since I was using a ported Mitsubishi manifold and the turbo hotside also had the bolt holes, I was able to keep my stock upper and stock lower (lower with a little modification) heatshields in place.

The temp differences can be felt as soon as the hood is opened. Either way, I never melted or destroyed anything due to heat. Not a single rad fan, alternator, P/S pump, etc and all those things had 250,000+ kms.

It must be a 2g thing
