problem w/turbo

ok......I really hope someone here can help me out. I have a 2000 prelude with a turbo kit on it. Sounds ok right?.............NOPE!!!
The prob is that my altenator is to close to the manifold and the damn thing spins off so much heat that I have gone through three altenators in as many months. It took three times till the guys at the shop could figure out why I was burning them up. The grease monkey tells me that there is like a wrap or some kinda manifold insulation you can put on to keep the heat contained a little. Any ideas what he is talking about or any other suggestions? I would really love it.

just get some header wrap and put it on the turbo manifold, wastegate, downpipe - you should be set. anyone got another reply that may help? I have never had a turbo and i am just speaking solely on textbook experience

i'd try heat wrap first, it's the most inexpensive, and easiest thing to try. if that don't work, you could "possibly" relocate the alternator, but it's a bitch, and i've only seen it done on old school motors, with a more give in the belts.

or maybe even a heatshield? like the factory one?

Thought about a heat sheild but the factory wont fit because of the wastegate. I would have to pre fab one myself. Think I'll try the wrap first. I read some stuff on the net about manifold wraps messing up the manifolds due to poor heat dispersion. Anyone else have any thoughts on this.

That is a myth. Allowing heat to escape from an exhaust manifold is a very nasty thing, not only filling your engine bay with hot air but also doing harm to your electronics, such as the alternator. It is why factory Preludes come with heat shields. You want your hot air (and subsequently, heat) to come out of the muffler, not in the engine bay.

yeah heat wrap should take care of the alternator problems
it shouldn't affect the manifold

i'm not trying to start something here, but i've seen it used to heavily, where it cracked the header. but i would have to admit it was a ceremic header, which may of had somethig to do with it. it's a lot harder to crack a steel one, unless it's a pacesetter :smile:

Watch out for the Header rap it holds moisture due to the heating and cooling of metal objects.
I only saw this on a header, and that is why this one was craked.

I think this guy is talking about the really shiny expensive heat shield tape. Ask Dealer for muff shop.

ROFL! PACESETTER! :smokin:
I'm surprised that company still even exists.

I've heard a ton of stories of "a friend of a friend" where the header would crack due to the heat sealed in the manifold. Unless it was a straight ceramic header, this is utter bullshit, and even if it were the case your heat shield would be causing your stock exhaust manifold to crack right from the factory. Stainless steel or ceramic coated stainless steel should not have any problems at all with this.

The claim that moisture accumulated on the wrap rusts the header is only valid if the manifold is made from a straight mild steel. Even so, on a higher quality piece, a mild steel header should not rust.

Is the wrap sticky, or do you have to connect the end - after wrapping- with duct tape or something?

I guess I'm asking a really noob question, but how do you apply/install heat wrap to your header?

This guy used clamps:

Hell try it, no better yet, tell us and show us what the outcome is.

dude, i said i wasn't trying to start anything. i'm not full of it. i have worked at my family's salvage yard since i was 9 tearing shit off cars. i have seen a lot of cracked headers/manifolds. they crack from heat issues. you get metal too hot it will force a place to displace it. the header is the hottest, most congested part of the exhaust. you force it to get too hot, it will crack, just like they crack if you overheat your motor, in any car. we sell many manifolds and headers at our buisness. b/c..... they crack.

i am not against heat wrap. i have it on my car. i just think, over use can be achieved.

my two cents...

i know this solution would be a pain in the ass...but don't most parts stores sell alternators with a lifetime warranty? they have to keep replacing it for free...so i don't see a rush to fix this or risk your manifold.

I apologize dbebisi, I wasn't insinuating that you were full of shit nor was I trying to suggest the point. I was saying that around where I live, alot of people have been spreading the word around about this. Stock headers come with a heat shield, why do they not crack from the heat held in by that? As someone who's used heat wrap on his Talon TSI manifold (it worked great on a turbo car) for nearly two years without problems, I just saw that this claim was unfair.

All this has reminded me to buy a roll of heat wrap.

Cheers.

no man, it's cool. i trust your advice more than anyone else on here (no offense anyone, he know's his shit). the funny thing is, we both have used it without problems, so i guess i would look like the dumbass. as far as the heatshield goes, it's use is to protect other parts of the engine compartment, and your bay heat level. but it's not wraped tightly around the tubing. the heat wrap is, and it serves a good purpose. i will rephase my original comment : heat wrap is good. use it. i use it. don't wrap your header with so much it looks like a giant blob. do a single or double layer. one roll worth. my own two eyes have seen an extrememly over wrapped header, that was ceramic coated (which i suggest not to use heat wrap with) and it looked like a giant blob. the pipe cracked off at a welded seam. and as he was pulling off the heat wrap. i laughed my ass off. so don't be like that doof, in his pimped out sunfire :smile:
