Exhaust Manifold Wrap

[dsgrntld187]

Ok I've seen those manifold wraps that supposedly lower the engine bay temperature. Is that BS or is it true? If it's true, would wrapping the crossover by my short arm intake help at all? You'd think it would if it lowers the temp at all.

Not totally sure about the header wrap, but I know for a fact that coated headers DRAMATICALLY drop the temperature in the engine bay. Damn things are cool to the touch.

hell yeah manifolds get upto like a bajilion degrees in a very little time.

[dsgrntld187]

Do they sell coated headers/manifolds for the 3100?

Headers and manifolds aren't quite the same thing here though. Headers are thin wall steel, and give off more heat. Manifolds are thick cast, and give off less heat. It'll still help some I would suppose though.

i have heard both sides of the story but i am gonna try it within the next few days so i will share my results when i get the time to wrap them up

[dsgrntld187]

If it works lemme know, I'll wrap the front one up and the radiator tubes also. Maybe this will be a good enough CAI for now.

Pros: lower under hood temp (u can wrap the manifolds and crossover, turbo if u got 1)

 

Cons: manifolds/crossover will get HOTTER and could crack, any salt/dirt will corrode faster when wrapped

[brian89gp]

coating- cools it off a noticable amount, acts as a real good paint so it doesn't rust as a bonus

 

wrap- cools it off 10x better then ceramic coating, but it WILL trap moisture and rust out whatever is underneath.

So would this work to keep heat out? Like on my upper intercooler pipe, which is right above the turbo and gets hot as hell. I'm assuming cooling this pipe might make a slight difference.

the cooler the air the better the turbo performs

[gp90se]

the cooler the air the better the turbo performs

 

thank you king obvious, the colder the air on any motor the better.

 

Greg, yes wrapping the upper intake pipe in good insolation will help, we have done it on a few cars, doubt u will feel the HP increase, but it might help to run slightly higher boost levels when racing.

Header wrap usually voids the warranties on aftermarket headers, so if that gives you a clue. I'm sure it couldn't really hurt a manifold though, not easily. Maybe replace it every 6 mos?

 

EDIT> Actually after thinking about that, I doubt you could even remove header wrap. It's probably sticky as hell and baked on after 6 mos of like 500* temperatures.
