So Mike doesnt have to spend all the time typing this again, This is what he emailed me today. its good stuff;
There are definite benefits in all of these coatings. I work in the r+d department for Dart Machinery(dart heads) ,and we have seen great overall improvements in our prostock racing program from these coatings. The pistons by far are one of the best gains, because you reduce friction between the piston and cylinder wall under high loads which reduces heat.The ceramic base on the tops of the pistons is where the extra power starts to come into play....let me explain...
Your main goal in creating high horse power is to produce high dynamic cylinder pressures in the cylinder .This is the main reason your running a turbo. Now pressure is produced in any engine by hot rapidly expanding gases in the cylinder which you apply to the top of the piston creating reciprocating motion into rotary motion at the crankshaft.
One thing that I have found is that you get some heat soak through different parts in the motor one being the piston and one being the cylinder head. when you ceramic coat the tops with this coating it helps retain heat in the cylinder by reflecting it back into the chamber of the head creating higher dynamic cylinder pressures which = Torq and torq is the building block for horsepower.Also one more advantage to the ceramic tops is if by chance you run into detonation it reduces the chances of melting the pistons you just spent good money for...remember heads can be welded and repaired, and pistons you throw away....just a thought.
Now when I coated my exh manifold , turbo housing , swing valve and lower plenum of my intake manifold it reduced heat under the hood temps tremendously ,and reduced intake temps by 20 deg after putting 20 psi through it. If you have any more questions call me on my cell 1(248)249-5983
I can explain more aboutthese coatings in less time. Call anytime.
Thanks Mike!
