I was wondering what you guys thought would be best for keeping under hood tempatures down. Either have my down pipe ceramic coated or wrap it in the header wrap you can get from Summit? Or maybe a combitation of bolth?

Thanks, CJ

CJ, we're experimenting more with doing ceramic coatings as of late. I'm not sure of the long-term effects of that on exhaust parts but I suspect they'll last awhile. It's definitely worth it on intake plumbing!

the dp might be ok, or at least the rear half, but i've seen a few ceramic coated turbos and the coating is gone in about 1-2k miles. besides its more fun to jessie james a heat sheild for the turbo

The exhaust housing on the turbo is allready coated, but what I was worried about was how close my wastegate was to the downpipe. There is only like 1" of space between the two. I just want to keep as much heat away from it as possiable. CJ

its been my experience that the wrap works well, although it is hard on whatever you're wrapping

ceramic coat inside and out.

Heat rejection seems like a surface phenomenon to me.

You want to keep heat away from your WG diaphragm and hose? Not sure of underhood temp issues?

I made my WG fit so the head was between the DP and trans and almost the lowest part on the chassis. It is right by the wheel so there is no clearance issues over road hazards (besides DP and suspension pivots are lower) and in good airstream. Not to mention getting that heft (HKS GT WG) low and back in the car.

I had Jet_Coat do both the inside as well as the outside of my FD3S SSDP....then, I'm wrapping it with Longacre header wrap...Hopefiully only about 15% of heat will be thrown off...the rest will go thru the Bonz cat and then the RB cat back.....

Heat wraps are a POS and a waste of money. Ceramic coat your downpipe. I had www.hpcoating.com do the extreme coating inside and outside of my downpipe and they did an outstanding job.

Also, you should never ceramic coat your turbo.

why dont u coat da turbo exhuast side & exhuast manifold?

billyrohm

If you cant choose between the two why not just do both. Maybe the wrap would help keep the ceramic on.

I'm probably just going to have it coated and be done with it. My exhaust manifold, and turbo came coated so I'll use it as is. Hope to have the car running by Nov. 15. Theres a dyno day, and I'd love to see what all my hard work has brought. CJ

Your turbos will not last as long as they should if you use ceramic coat, the heat needs to escape. Also, you should never use heat wraps, they will damage your parts.

In the 4 or so years I've owned my FD, I've put right around 4k miles on it. In that time its had every single bolt-on installed, and now a big single....I'm not worried about longevity. Shoot, If I get 5k miles out of the setup, I'll be happy. CJ

How about 1st coat then wrap the parts? eh

I know the wrap tend to trap moisture= rust

But if you coat it 1st= no rust right?

I think that the hipercoat extreme coating would work. Having the coating on the turbo won't kill its life that much faster. The heat will be kept in the turbine and sent through the down pipe, and heat won't soak into the other parts of the turbo as easily.
And kabooski, it would inhitit the rust. But I think that wrap ontop of the coating would kinda be a wate.
