exhaust manifold wrap

[Weirdo_Joe]

I used foil to protect the other parts of the car, rubber gloves soaked with the stuff to get the back, and I used a paintbrush for the second coat... the 1st picture is before painting. 2nd pic after one coat, 3rd and 4th when I was done. I replaced the manifold cover; I thoght about painting it, too, but then I thought that it's function may be to ABSORB heat, not reflect it... so I didn't. I did have to disconnect the recently installed O2 sensor to remove the cover; just the wire part, and that was cool, 'cos I needed to move where the plug was attached (I had it rigged-it was on top of the mount) now it's where it should be, and seriously: the improvement to initial speed (torque? Header wrap claims to raise torque...) was better and more noticable than expected! It makes me want to coat the CAI pipe with it, too! Probably just the outside... right? It's black... it would look cool, but would it get hotter? I think it's only radiant (light) heat that black absorbs... Also, I read something about cold air being more dense than hot air... if the exhaust isn't losing as much heat as it leaves the engine, it seems it could travel at higher velocity... would that be true? I had a TON of FUN doing this...
