question on jetcoating the manif.
alright, I am thinkin about going with the buschur ported/jet coated manifold (stock, exchange). But I was thinking... what is the jet coating really for? On the site it says to keep engine bay temps down... I feel that but the gaping hole over my manifold seems to do a good job of that. The only other issue that I feel is probably a factor is the heat going to the turbo... Now more heat to the turbo should mean more energy hence more power... but how much? I would think minimal. The other aspect of the heat going to the turbo would be durability of the turbo with greater inlet temps. I would think that both the manifold and turbo would be under greater thermal stresses b/c of the added heat in the system that was not allowed to radiate off of the manifold.
So is it really pretty much for looks? I know the rusty look isn't quite "in"... so is that pretty much it?

Thermal efficiency is needed as hot gases do hold more energy. Being that the manifold is cast iron, I dont believe failure is likely due to the heat. My worry is pieces of coating chipping off the inside of the manifold (if the inside were coated...i dont know) and coming in contact with the turbine.
These are great questions....i was thinking about this service as well.

The heat actually escapes faster. Heat being absorbed into the manifold just makes things hotter. Jet Hot coating and other coating have been proven for a while. I don't know about numbers, maybe someone might chime in. You don't want the heat to radiate off of the manifold. You want it to exit the engine as fast as you can.

the moves heat through faster, the reason you can touch your manifold 45 seconds after you turn the car.. heat is what drives the turbo, if the exhaust gases arent hot there useless too the turbo.. it will make a diff, esp under hood temps.. and it is proven to work.. also if you do it i would strongly recommened doing the inside and out... i have to send my tube header out to be done soon.. i just havent found someone close to do it yet... i know the guys at o.c.c. have a guy close buy who does it..

Do it yourself and stop asking the question over and over again. Obviously no one has any difinitive answers for you, so go do it yourself!!!!!!!!
Here read this, it is more thatn a couple hundred degrees
