i finally put my manifold on my car today and i have a question about the heat of it. it will be ceramic coated before the start up but the top of the manifold(like the 180 bend runners) the two runners that are the closest to the valve cover are like .25 inches away from the valve cover. since i will be getting this ceamic coated, do you think it will be ok or should i see if i can fix it? thanks guys

 

what do you guys think? its at most 1/4" from the valve cover, and its ceramic coated.

 

you could fab a heat sheild to help block some of the heat. but it will help only a lil. most of the heat issues should be resloved when the car in motion. a vented hood might help also.

 

anyone else?

 

ill have pics tonight, but what exactly is the stuff on the valve cover?

 

is the valve cover powdercoated?

 

heat wrap and heat shield will help

 

so lets say i get it ceramic coated the i just wrap the two runners close to the valve cover, good idea

 

wrap it all. if you dont, youll have unequal gas velocities in the different runners.

 

alright i see, how much does the coating help with the heat on the outside of the pipe

 

not too much. its mainly for inside heat. the wrap will give you the best results for inside and outside.

 

alright thanks man, mine is just a little closer than lovefabs is from the valve cover, so ill coat it and wrap it

 

So let me get this straight; your concern is that you will melt the powder coat on your valve cover. Correct? Now that powder coating was designed by honda to stand up the temperatures put off by the head. It's designed to stand up to substantial heat. If the headers are ceramic coated I doubt that they would be able to transfer enough heat to the valve cover to cause the paint to melt. If the header is as high as you say I would be more worried about the hood.

If this is a manifold you bought, did you considered asking the company if they have had any problems with it?

also, i talked to HPC coatings and the guy up there told me that if you're going to ceramic coat the manifold...DO NOT heat wrap it. thats just what i was told

besides, that ceramic coat helps alot i dont think you'll have problems with the heat messing up the valve cover. what kind of manifold is this? i've never read of anybody having problems like this.

 

there uploading now

 

i think you have to host pics on the net before you can post them

 

what do you guys think of the clearance between the valve cover and the two runners?

 

thats fine, just wrap it and be done

 

I woulden't touch it after the ceramic coating. I would even run it like that with no coating. Air is a remarkably good insulator and since it should be at least breezy under there I don't think it will matter.

 

so once i get it coated, my valve cover will be fine you think?

 

anyone?

 

You'll be fine. Mine sits close like that and I have yet to see the heat deteriorate my valve cover or anything else.

 

ok thats good to know, thanks guys

 

are you afraid to wrap it becuase thats the best idea on this thread

 

it will be ceamic coated
