Got My OBX Headers Today

wouldn't less under hood heat lead to slightly better performance?

Theoretically. But, how much affect is it really going to make in the ZR-1?

If you cut off coolant to the TB, it is amazing how cool the plenum runs. Will the cost of ceramic coating justify the difference in under hood temps? At WOT, the amount of heat contained in the aluminum is quickly absorbed by the mass of the incoming air flow - negating whatever heat there was at idle.

Yeah, I know racers will ice their motors between quarter mile runs. But, that has more to do with lowering water and thus combustion chamber temps to take advantage of some spark and fuel advantages afforded by the cooler motor.

All I'm saying is, "Let the buyer beware!". Automotive catalogs and car magazines are filled with gizmos and tricks that claim to enhance performance. Some work and some are BS, and some will actually hurt performance when applied without taking into account all the other pieces that are necessary to achieve good results.

As far as coating goes...

I didn't coat mine.
The difference to inside cabin temps are - far as I can tell - negligible.
My intake plenum runs cool after cutting off coolant to the TB.
I'm making 432 rwhp on stock cams.
I haven't seen any data to convince me coating my particular (SW) headers would do anything.
There's lots of snake oil out there....

Your mileage may vary.

I have my "Cyclonator" that generates cyclone action vortex resulting in fuel atomization that leads to 10% increase in power and 10% decrease in fuel consumption - $19.99!

Oh... That must be a secret WAZOO approach to performance!
