heat shields

[hannibal]

I came across some T3 and T4 heat shields on this site.http://64.225.76.178/main.htm

The link is under the "New" section on the left.

wow, those look really nice. i didnt want to spend the money or wait for some so i made my own out of sheet metal. they are working great.

i can get you heat shield (blanket) for T3 or T4, which is far more superior. let's put it this way, after hard runs, you can touch the heat blanket with your bare hand.

email me; [email protected] i'll hook you up with a better deal than that non-efficient metal shield.

blanket over a t3/t4 on an s15 sr20det, chrome style

blanket over a T-series turbo on a 2jz supra, black style

[TrunkMonkey]

you'll be replacing that heat blanket after it gets ripped or oil/coolant soaked. they do work, but aren't even close to being as durable as a metal heat shield.

unless you're blowing your turbo left and right. i'm sure you know how heat are retained in those stainless steel metal covers--might as well go without a shield. i would go with aluminum, however--if you're sticking with that type of shield; because they cool down faster than stainless

[TrunkMonkey]

metal heat shields (especially stainless steel) will lower underhood temps. will it be cool to the touch like a blanket? nope, it's metal. but it does serve it's purpose of protecting surrounding parts from high exhaust temps.

anyone ever remove the oem heat shield from their oem exhaust manifold? there's a big jump in underhood engine temps with out it. not enough to do any damage, but it is very noticeable.

if blankets were dirt cheap i'd be all for them, but i've seen them go for as much as a metal heat shield. in most cases, if you have to replace it even once, you've paid the price for a metal one.

i definately agree with you. oem shield are aluminum, if i can recall correctly! aluminum does dispearse faster.

[TrunkMonkey]

i don't remember what the oem heat shield is made of and it waaaay to cold for me to go outside and check. regardless, aluminum is the worst metal to use because it transfers so much heat. stainless steel is the best way to go.

my first drive w/ my kat lasted only 2 or 3 minutes and i never once boosted. when i opened the hood, there was an ungodly amount of heat under there. a lot more than i had ever felt when i was n/a w/ headers. i custom made a heat sheild for the turbo and manifold and drove the car again for much longer. the difference was amazing with just those 2 small heat shields made of sheet metal.

[daniel240]

and im pretty sure the oem shield is metal, i just had it off and i was looking at it and there was rust on it.

[whiterps13]

besides protecting your engine bay from heat, i heard that a heat shield can conserve heat within the turbo, thus making it spool faster? can anyone confirm this?

[TurboKA37]

hmm, i took my stock heat sheild off a couple months ago cuz i thought it was pretty ugly. do you suggest i put it back on?

[C-Kwik]

Retaining heat in the turbine will make a turbo run more efficiently, but if you are only using a shield, it's not going to be significant. Shields trap a small amount of heat as there will ba a higher amount of heat trapped between the turbine housing and the shield. But some of the heat will still escape.

As far as my take on heat shields, I would focus more on protecting eveything else in the engine compartment from heat first. Retaining heat would not be a priority for me in looking at a heat shield. IN fact, I'd opt for the better looking heat shield before I cared how much heat it held in. If I was that concerned about retaining heat, I'd probably opt for a coating of some kind first. The stainless steel ones at Performance Turbochargers are nice. I'd have one, except, I'm too lazy to tap the turbine housing to accept bolts. And there's no way to tighten a nut and bolt if the heat shield is there. My cheap turbonetics heat shield will just have to do...

has anyone looked into inconel turbine heatshields?I got one on my car and in result I did not have to block heat away from the brake fluid resevoir or anything else. Its a 2 piece design and fits over the turbine. They are not cheap but it is better than ceramic coating. This is NASA material. IT does not rot or burn up.Here's the site for pictures:http://www.atpwrap.com/albumframeimport.htm Here's where u buy them:http://www.twinsturbo.com I attatched a picture of what it looks like on my turbine below.

I found another possible heat shield at Target, a stainless steel cookie sheet. (Yes, it's the only place I could find a large flat sheet of stainless steel easily). Only 24.99

[fiznat]

They are not cheap...

No kidding! Christ, $325 for a heat sheild!?!? I dont care if Mr. Nasa made it himself in his special Nasa lab. Its a HEAT SHEILD.

[andrave]

Mr. Nasa?

[Nathan]

Fiznat is a "special" nincompoop.

[fiznat]

haha thats right, MR NASA.

[klattr1]

i know, i know, the price is really high but I didnt pay that much when I bought mine.My dad has seen inconel at nuclear power plants on pipes that heat up to like 3000 degrees. So I know its definitely good. I'm sure it helps spooling the turbo since it keeps all that eat internally(heat will drive the turbine wheel).I was just wanting to show yall whats out there. I know I'm not the only one that uses it also. F1 indy cars use it on there turbines and manifolds. Remember they run like 60 psi of boost on those motors also.

[hannibal]

Anyone know what it cost to ceramic coat the turbine? What else would you coat to keep the heat in? Downpipe, manifold??

[fiznat]

hey klattr, that wasnt an attack against you or whatever, I'd be glad to have one of those things... I'll just be god dammed if the heat sheild costs half as much as the whole damn turbo does! haha anyways, you're lucky you got one

[aleph1]

Swain "White Lightning" coating seems pretty good, a TRUE ceramic coating.

[klattr1]

Jet Hot is nice but even it still cracks. Coat the manifold, downpipe, and the turbine. The housing will come off with like 6 bolts or so. It depends who makes your turbo for how many bolts there is but ceramic coating makes a world of difference also. Thats why I got my downpipe and manifold down. It cost like $120 for downpipe and manifold.

[andrave]

I'm going with heat blankets for mine, probably, and heat shielding for the master cylinder and distributor.

[S14tat]

i bought my sheet of steel from homedepot for 3 dollars. and i made one. before i put it on, it boiled my brake fluid and i couldn't stop. i had to hitch a ride in my friends car to take me to homedepot to buy a sheet of metal. also it melted my old brake master cylinder reservoir. but it doens't matter anymore cause i got a heat shield on it, and a new Z32 brake master cylinder swap. now i dont' have to worry about even the pedal gettin soft from heat.

[andrave]

what about shielding the master cylinder, too?I mean half the problem is reducing the overall heat, by shielding the turbo from the engine bay. the other half is reducing the effect of heat on heat sensitive components.

[TrunkMonkey]

cut off the problem at the source and you won't have any issues. even the simplest heat shield around the turbo (even thin sheet metal) has been proven to protect the master cylinder.

imo, too many heat shields in the engine bay makes it look messy.

lol whoever sells them that much are crazy. AHEM; email me if you want one for $145 shipped.

but yours are not inconel. Just research into the material a little and you will understand the pricing.http://www.burnsstainless.com/TechArtic ... ticle.html http://www.thermostatic.com/techdata/in ... rcraft.htm
