Now that you mention it, I wonder if it's the same heat that rots out strut towers

doesn't hot air travel faster than cold air?

so having this blanket to retain heat would hypothetically help spool the turbo faster..?

Yeah, that's what I kept reading when I bought my tubular manifold which is why I wrapped it, it cracked pretty soon after (ebay).

Alright, I'll bite... what am I missing here? You state that you never had any failures from heat but you also state you were running factory heatshields. How does this prove that heat generated from the turbo/mani aren't an issue?

Heat kills things, it might not happen right away but it will shorten the lifespan of most parts. There is a reason why they had heatshields from the factory. If running the stock heatshields was an option, I'd probably still have them but for some people its not & a blanket is the only option.

An Ebay manifold cracked?..... What a surprise

There was a time before I got the heat shields where I didn't run a single shield. No shields, no blankets, not even any heat wrap. My old FWD, same story. But once I did get the OEM heat shields, I noticed a big improvement in cooler underhood temperatures.

LOL, I was a newb then and was not aware that they could crack that easily, so I was pretty pissed. I have hear that if you enforce the welds then a ebay manifold will actually stand up to the heat.

tried that, still doesn't work. fp ftw!

Just re-doing the welds probably won't do much, think the guys that do it & have the best luck add additional braces. If you properly support the weight of the turbo, any tubular mani will last much longer without cracking. Its the weight, combined with heating & cooling that does them in. Think even the Ebay ones can do alright, if the turbo has been supported.

So we obviously know that these heat sheilds and blankets reduce underhood temps.

What explains ALL the CRACKED oem 1g and 2g exhaust manifolds that came on our cars, with OEM heatshields? I remember back in the days, you would go and remove your OEM heatshield and what a nicely cracked exhaust manifold you would find underneath

Just saying...

None of mine cracked (granted I started with an Evo manifold). You also have to remember that the heat shield is also a security/safety measure they need to take so people don't go touching hot parts (hence the little hand showing "No touchy" :p). So the manufacturer also has lawsuits/safety in mind.

Now Reza, then you have the same saying if water hits your unprotected manifold when it's piping hot (rainy days). Crackadie-cracklakers This is true for pretty much everyone who runs a vented hood with the vent over the manifold. It depends on your setup, what compromises you're ok to take and if you want something that look nice as a bonus. All mods won't be the cup of tea for everyone. Not saying you're wrong, but something can always be said to counter one argument and then the other. So this thread will last forever

Basically, yes they have a function. Do they compromise other things, also, yes. That's what life always gives you, 1 good, 1 bad, never all good If everything always functioned for one purpose and did it 100%, no one would ever need mechanics/tuners/maintenance/replacement parts.

Yes I get your point I just wanted to point out the cracked and warped OEM manifolds on every DSM out there with an OEM heat shield(in case anyone wants to bring up the heat shield argument), thats all. Any person who has been into DSM's long enough will agree with me. Just something to think about

Do I want the same sh!t happening to my FP manifold? Quite frankly, no. I'm not saying you shouldn't buy the blanket. Just thought I'd point out a few things before everyone jumps on the band wagon. By all means go for it, if that is what your car truly needs In fact Ziggy should do a group buy for you guys who really need this item

I run metal SS ones since they work for the HAFE and EVO manifolds I have. I kept the original bolt-on configuration in my manifold choices for that reason. Not big on covering with blankets/wrap because of the humidity and chemical reactions that happen because of it over time. Afterall, manufacturers look for the cheapest long lasting choice for things (well before...these days..what breaks quicker after warranty) and they chose metal.

I believe the evo3 exhaust manifolds were made with a higher nickel content to prevent cracking. On another note my previous 1g manifolds had cracks, my 2g one if I recall correctly never did, they might be less prone to it??? Heat shields or not, didn't matter in my case.

my 2g mani started cracking on the top near the 3rd runner right in the middle.

+1...my 2g manifold also cracked and this was while the car was un-modded and running a T-25 on 94 octane gas! I've got a 'CAST SS' manifold now to ensure it wont happen again.

My OEM hood is missing the heat reflector shield and my manifold is missing the heat shield, as a result my hood has a plethora of small heat cracks that looks like a cat tried to tenderize my hood's paint.

My 1g came with a cracked 1g manifold. I am going to try the blanket and see how it does with the 2g manifold I have now.

DEI make's a "cut to shape" 3/4inch thick reflective heat pads that stick onto the underside of your hood. I'll try and find the link, there's a name for it just not remembering lol

here it is;

That's cool! I think I may go for that cause I don't want the hanging shield I have now.

i'm definitely doing this aswell, maybe we can get the zigster to group buy

LOL, we should just make a list of stuff we need a group by on

looool group buy some lambo's forget dsm's altogether hahaa jk

could never do that

I just put this on the underside of my hood: http://www.designengineering.com/ca...r-tunnel-shield-ii-heat-sound-insulation

Similar but tougher. Had to do it as the underside frame of my carbon fiber hood was getting soft (when hot) from the heat under there.

Doesn't serve the same purpose but that's much better looking then the stock crap.

Prosport has their titanium turbo blanket(fits 16g) on sale right now for $110, and if you use the coupon code "mitsu" it comes down to $99.

OK, this has totally changed direction from the beginning, so I sort of just "let it go". We also seem to have wandered from manifold blankets to turbo blankets. Now I have had ONE person tell me they are DEFINITELY interested in one of these FP manifold blankets, so I will be contacting the vendor shortly to see what sort of pricing I can get.

Without getting into why these would or would not be good, is anyone else interested in them?

Yeah I guess I goofed when I titled the thread, was supposed to be manifold blanket.

I am interested in one.

I am going to start a new thread in the commercial section. Please check that out and add your name/colour choice there.

Any one interested in seeing intake temperature differences or any thing else?

Absolutely.

Ok I will just go out and do a log without it and then toss it on and do a log.

Very interested

So I took it out yesterday, I goofed somehow so my logs for after the blanket went on don't seem to be there.

The turbo definitely hits boost earlier. I will go out and take some longs in the next while and see if I can get any data and report back

So the blanket came off yesterday. I just put in 1000cc injectors and am trying to tune those and the car is getting way too hot (especially with this retarded ass weather) so I will be running without it until I am happy with my tune then I am sure I will put it back on.

Bringing back the dead on this one, but I felt bad having real world results and not posting them in case they may be of assistance to someone.

With a turbo blanket only on a day colder by 10*C on average (Used weather.org to check the weather for the days of these logs), I had a minimum/maximum intake temperature of 129/158*F and WITH a manifold and turbo blanket, I recorded temps of 57/73*F. Both are from a drive to/from work and are excluding initial warm up idling.

Wow, didn't think we would see difference like that. Also thos first temps are really bad, normal is around your second temps.
Any difference in spool?

I'm not too sure, but I'm also sure that I changed my tune a bunch by then as well.
