Header Wrap [Merged 3-8] thermal DEI headers exhaust

[MNGSX]

That ceramic coating is some good looking stuff.

I know it has an inulative value but I don't think it approaches that of wrap.

I recomend putting the heat screen or "thermal blanket" looking stuff over the wrap. In fact you can probably attatch it to the factory heat sheild if you want. I prefer wraping the manifold directly so I can seal it better then install the factory heat sheild over the top.

I would'nt actually buy the turbo wrap kit but make my own wrap from the heat screen sheet.

As for the a tubular O2 and downpipe wrap it in the header wrap. Then cut the heat screen to 1" wider strips than the circumference. Wrap it Around the pipe. Violla. Sealed and very insulated. This combines the use of air pocket style insulation (header wrap) with radiant heat reflection.

If it looks good or not depends on who did it.

If you do a really do a good job it does look a bit more NASA than bling but I can live with it.

anybody ever used the turbo insulation wrap kits? all the big boys use em in pro racing and the logic behind it is simple, yet effective. Here is where my questions comes in, if we were to use this on our turbos, would the internal wastegate actuator be able to move and open like it is suposed to? I would like to hear from people's experiences.


Also, has anybody tries insulating the intercooler piping to the tb? i know it gets warm under the hood, or perhaps even the intake pipe that goes to the turbo?

What do you all think?

I've used the DEI tape on the intake tubing on my Miata w/ awesome results. Since most intake piping ( especially FMIC piping ) passes behind the radiator and fans, the compressed air is going to pick up some of that heat from the tubing. I plan on wrapping my whole FMIC tubing w/ the DEI tape. As for turbo insulation kits, I prefer my turbo's rare, not well done. Do it if you want to bake your turbo. Sounds dangerous to me since turbo's put down alot of BTUs and insulating it could be dangerous.

Well the reason you wrap is because hotter gases are less dense than cooler ones, so if you wrap your turbo and exhaust manifold the exhaust would be a higher temp, which in turn flows faster. Also it's to get some of the heat away from other things like Groomz said...

just got a new ss 3" exhaust and ordered some exhaust wrap. then i read wrap might cause hot spots that can cause cracks and that's the last thing i need on my new exhaust. my friends gvr4 has a wrapped dp and it's rusting pretty bad, don't know if it's ss or not.
anyone using/used exhaust wrap, is it worth it?

Yes it can cause hot spots. A lot of people are going with coatings these days. www.jet-hot.com I believe.

jet hot > heat wrap and ceramic coat

jdmawd, how much did that cost? Looks great.

$340 including shipping both ways. The flash makes the coating appear not as dark but in actuality the coating is very black.

 

[tsunari]

Considering wrapping my exhaust from O2/DP all the way back to the muffler. Any feedback on benefits/problems I may encounter?

 

[Defiant]

Not much point after the turbine. Why do you want to use so much?

 

[tsunari]

figured keeping the temps up would increase the escape velocity of the exhaust gases. Perhaps it really doesn't matter with a 3" exhaust?

If that's the case, what SHOULD be wrapped- if anything?

Remove your exaust manifold and wrap it and then wrap the turbine housing on the exaust side.

There's one pic of my turbo before I installed it with wrap on just about everything, hehe. I did it because I had no heat shielding on my 50-trim and thus needed something to keep everything around it from melting. So far it's worked. I just wonder how long it'll last until I have to re-do it... I was so itchy afterwards so I'm not looking forward to it, haha. Anyway, the only way I can gauge the success is by me putting my hand near it (since I didn't think to take any sort of measurements beforehand, and don't have instrumentation to do so, hehe)... but I can put my hand within about 1-2", but it's REALLY warm any closer and it starts to hurt too much.

Wow, talk about scientific, eh? Sounds like this should be an episode of Jackass

 

[dthquazi1]

what do you guys think about the turbine wrap kits. Are they worth it or would just any sort of exhaustwrap work?

 

[Robby Camero]

IMHO, the only thing worth wrapping is the o2 housing and upper part of the down pipe to protect the alternator.

My friend tried to wrap his mannifold and it looks like HELL. If you want to keep the manifold hot, or keep the heat contained, get it ceramic coated. Looks sweet too!

 

[jake98gst]

From what I've heard, exhaust wrapping causes hot spots. If you want to control temps to the same effect as wrap, get it jethot coated (nice but expensive), or get it ceramic coated by FFWD Connection ...$100 for a manifold I think. Look into something like that instead of wrapping I would think.

More on the ghetto side: I've heard/seen pictures of people simply wrapping their manifold or whatever in aluminum foil - that's right...Reynold's Wrap - to work as a pseudo-heat shield. They claim they actually felt a difference in underhood temps.

Well, that -gulp- should work, because you'd get some air between each layer. But gawd, it's gonna be grisly looking real soon.

actually,header wrap works in other ways . We all no it keeps temps down wich prevents over heat damage from aftermarket parts,plus the colder the air in your intake the dencer the air is the more cumbustable in the cumbustion chamber[more hp] but theres another catch, the hotter the air coming out through your header the net efect will be greater velocity,greater pressure drop in the system and higher efficintcy[little more power]

Ahh yes! Finally someone who mentions proper scavenging which is the MAIN reason (other than lowering temps) to use header wrap.

 

[fr33b1rth]

header wrap is not necessairy, although it will lower your underhood temps, as well as help encourage a well flowing exhaust because it will keep the heat inside the header rather than being absorbed and radiated.

 

[InfamousEclipse]

The way my pipes are, on my FMIC Turbo 420a, the intake pipe is close to the Downpipe... I really need to wrap this in heat wrap but know nothing about it.

Where can I get it, how much, what tips do you guys have?

Thanks!

 

[evan2]

are you trying to wrap the dp or intake piping?
if you mean the dp, its kinda up and down

some say they are all for it, some say to stay away from it. Reason being is the fact that it traps in heat and will trap in mositure, they think it will make the dp prone to cracking. Maybe its just for exhaust manifolds, becuase I have seen many dps with wrap.

or a high temp spray on them

look into it more, but do a search online for it

I picked some up at my local tuner parts store. It has directions on the box. The only suggestion I have is to get the two inch (wide) and also take the part off of the car before attempting to wrap. I used hose clamps at both ends. All you need to do is start wrapping and then clamp down one end and continue to the other end. The wrap has guidelines that make it even easier. There is also an adhesive spray you can buy. IMO you don't need it, just wrap it tight. Doing the intake ans I/C pipes is not as much of a pain in the ass as exhaust. Exhaust has to be done right or you will create heat spots. But thats beside the point. Hope this helps. Laters.
