Little bit at a time...
I decided pay special attention to the pistons, since they are a critical part of the engine's ability to make dependable power. For durability and efficiency, I smoothed the sharp edges on the valve reliefs and sent the pistons off for some coating work by
DART COATINGS.
The Temperature Reflective coating is done to the top of the piston to increse burn energy while keeping the piston cool. It's a zirconium-titanium ceramic which has a gold color and is bonded to the aluminum.
The Anti-Friction coating is added to the skirts to keep friction minimal along the cylinder walls. It is a Flouropolymer/Moly mixture which is slick like Teflon, but much more resistant to contact with metal.
I also had the exhaust valves coated with the Temperature Reflective coating to handle the turbocharged heat a little better.
If nothing else, it will be a nice
looking engine when assembled.
