Do you think painting the SC, valve covers and other items on the engine will be greatly effected by more heat because of the black paint, or not enough difference to recognize? dunno

shouldn't make any difference. i'v seen a lot of the GTPs with black blowers i think stock? the light/dark theory applies mostly to radiant heat from the sun. the sun doesnt contact the motor at all so in that respect it makes no difference. I suppose the paint its self adds an immeasurably small amount of thermal insulation which doesnt help your engine but in the practical world, you won't notice the difference.

that shows that you don't want to use the wrong paint. I promise you can paint it

Yes you can, but you don't want to because it will cost you performance.

Thanks for the link. GOOD LORD! Three pages of debate. I guess it basically comes down to the decision: are you going to race it or are you going to show it. It CAN be painted but it will cost you some power in the long run. Thanks guys. neutral

he heated the thing to 350 with the mystery paint out cooling the housing we know our engines get to 210 if not 180 with thermestat down . I dont see how the housing beeing stock grey dipped to black would interfer with the internal temps only out i understand it would breath as well letting it off but not sure what actural horse would be lost from slighty hotter air i mean mi-nutely hotter with most of us running aftermartket air intakes for colder air anyway.

For daily driving, it won't matter, and if you're someone who would remove the blower for the sole purpose of painting it, I'm guessing you could care less about a few lost hp.

But for outright performance, every degree of heat, every CFM of air, every degree of timing does matter, and the Bonneville guys have shown that aside from looks, painting the blower is not a good idea. Our engines operate right on the verge of detonation; when you run smaller SC pulleys, the KR threshold moves even closer. Just a little adjustment here or there could mean the difference of having KR or not. And as you know, KR pulls timing, which drops power levels. In racing, winning by a few feet means being quicker by milliseconds.

The guy on the forum that put the SC in the oven has done alot of research into it. And has one of the quickest series 1 Supercharged cars around. Again it depends if you want performance or show.

I could be wrong, but I think the supercharger gets hotter than 210 degrees. When you compress air you get a lot of heat.

agree

Correct. Outlet temps of compressed air passing through the M90 blower can exceed 270ºF.
