here goes another thread about tubular manifold .... i have an custom made tubular manifold , the manifols has no heat coating or podwer coating what so ever.... and i dont want to heat coated do u think heat wrapping it will bw a good idea please guys help me im kinda fustrated ... thnaks lots

 

Heat wrap will keep more heat energy in the manifold, and in turn, more energy to your turbo. More energy = more power. If you can heat wrap it, I would. Not to mention it'll help keep underhood temperatures down too.

 

post pics of the manifold.. Coating is your best bet.. Heat wrap will trap the moisture and can ruin the manifold..

 

true

 

Heat wrapping an exhaust manifold can be a fire hazard. If that material becomes oil soaked it can catch fire, especially at 1350-1550 F* surface temps. It happeed to a friend's car.

 

go for it wrap the sucker

 

Only if it's applied incorrectly.



Again, if done incorrectly.

 

I would suggest the swain tech coating

 

how do you suggest doing it that will make the material not absorb moisture and cause the the wrap to deteriorate the piping??

 

I'm not an advocate of heating wrapping, but if done correctly, it can be quite effective. There are 2 different coatings you are supposed to apply in addition to the actual heat wrap material. The first is an adhesive coating, to make sure the heat wrap sticks to the manifold. After you apply the wrap tightly, there is a second coat of spray-on sealer, that basically is a high-temp water proofing. This keeps the heat wrap from absorbing moisture and retaining it.


However, very few people actually follow the instructions for proper heat wrapping, and thus, you get the results mentioned. I've seen a lot of guys on here just wrap the heat wrap around their manifold, then use a hose-clamp to hold it on.

 

I would never think of heat wrapping a daily driven car with a tubular manifold. I've seen way to many manifolds crack because of the amount of heat, plus moisture being trapped inside. This is something I would consider doing on a full-out race car, but def. not something driven on the street. Just my .02 cents.

 

I heat coated it and then wrapped my manifold really tight and then sprayed the wrap with a DEI silicone spray to keep the wrap from getting any kind of moisture...works great I think

 

just wondering why you dont want to coat it?
