Re:N.A.S.A paint for manifold ( don't laugh )
I know nothing about the space shuttle or N.A.S.A. for that matter it just looked just like the same paint and texture they coat it with. What ever he used it waqs keeping the Valve cover cool. Like I said I didn't even think you could paint a turbo but I was just thinking of some possiblities since I keep hearing that Heat robs power from your engine. Oh well

Re:N.A.S.A paint for manifold ( don't laugh )
ummm, I can tell you it is not the paint used at NASA. They don't use paint on the shuttle. Taken from a NASA site:
The HRSI tiles are coated on the top and sides with a mixture of powdered tetrasilicide and borosilicate glass with a liquid carrier. This material is sprayed on the tile to coating thicknesses of 16 to 18 mils. The coated tiles then are placed in an oven and heated to a temperature of 2,300 F. This results in a black, waterproof glossy coating that has a surface emittance of 0.85 and a solar absorptance of about 0.85. After the ceramic coating heating process, the remaining silica fibers are treated with a silicon resin to provide bulk waterproofing

Well like I siad I know nothing about NASA and still don't. I didn't believe him but the valve cover was cool so what ever he used was good sh*t and not some crapy pep boys high temp ricer yellow paint. I'm just not going to go out and buy a bunch of cans of paint to find out what he used. I'm just sharing with you guys what I saw and what potential the paint he used has thats all.

so where do you get tetrahomocide and boromymate at?
http://www.holtsauto.com/products/94.htm
Protects at temperatures up to 1200º F, 650º C
Originally developed for the Apollo Space programme
----------
1200F is pretty standard.. look for a barbeque or stove paint.
http://www.forrestpaint.com/stovebri...k_liquid1.html
http://www.por15.com/hightempcoatings.html
1400F
dont seem to have anything greater that available anywhere
-----------
When heated, epoxy paints are TOXIC and cannot and should not be used on food equipment like barbecue pits. The paint breaks down when heated and gets inhaled, so to speak. Not real good for you. You might not die right away, but it may be harmful to you.
---------
If you coat mufflers, fireplaces, barbeques, or just about anything else with surface temperatures greater than 500°F, you should consider a silicone based coating. Over 500°F organic material will degrade rapidly, causing decrease in gloss, discoloration and loss of film integrity.

Just my 2 cents

There is ABSOLUTELY NO Form of excessive heat which is good for any engine part (except for a cat. converter of course). And unless u have a track/race car, where u expect to tear down ur car and rebuild it every so often, header wrap, etc. is shitty. It will break down a well-built NA ceramic Header within 6 months with daily driving (seen it b4), that's why all major header manuf. void warranties when u use wrap on headers (DC, etc.). The 1/2 HP gain u get from ur engine bay being cooler is not worth the overheating/working ur exhaust/turbo system...
If anybody's in the southern cali area, I've got some flat black NASA paint for sale - $49.95 a can... Pay No Attention to the RUSTOLEUM Label...

Re:N.A.S.A paint for manifold ( don't laugh )
sorry but i know people that have been running w/ header wrap for 3 years now... the reason people have problems is they don't take care of the car the way it NEEDS to be taken care of... if you put the car away wet yes it will cause rust that will eat right though the header in a matter of months... not good... simple solution... don't let the wrap get wet... or if it does leave the car in the garage running... it'll dry the ---- quick enuff... then shut the car off... wetness is what causes the problems... which in the end is the uses fault.
as for heat not being good... why do you bump compresson ratio in a motor? why do you ceramic coat internals... and the likes? to create more heat... think a turbo is driven purely by the air "blown" out of the motor and though the turbo? hell no... it's the heat that spools the turbo... keeping heat in the manifold forces it though the turbo... that is a good thing... just like ceramic coating the internals and bumping c/r which cause higher EGT's it forces warmer air though the turbine... you also get the benift of keeping some of the heat from the manifold from raising the underhood temps... thats good.
charge pipes however shouldn't be coated... idealy you want to use aluminum for a charge pipe (or a metal w/ similar heat transfer capibilities) alu transfers heat VERY well... heat will radiat though the pipe... w/ the high charge temps of a turbo (assuming they are higher then under hood temps) will radiate out creating a cooler more dense air inside the charge pipe... in essence giving you a mini IC effect (although minute)... steel on the other hand doesn't transfer heat very well... ever notice what they use for heat sheilds... wonder why? it doesn't allow near the heat to transfer though the sheild... steel for this reason (and the fact that it weighs a lot more then the same thickness of alu) makes for a poor charge pipe... on the other hand it's great for a CAI as it won't "heatsoak" the intake charge like an alu CAI would.
just my $2.02

Heat is a By-product of ENERGY (High School Physics MANNN!!!) Turbos & High compression make lots of energy, that's why they produce more heat (this is because an engine/turbo is not 100% efficient, if it was, it would produce NO HEAT AT ALL - more HS Physics) HEAT IS BAD and unwanted... that's why U retard ur timing when u run boost - to decrease heat... that's why detonation occurs in high comp engines - HEAT... If heat made energy, why don't we have Electric heaters in place of our intercoolers
Why don't we get rid of our cold air Intakes and stick a cone filter next to our exhaust manifold (for more heat) Come on man... that's common sense...
