I can turn over a race engine by twisting the alternator pulley. What is it that you plan to fix with this coating?
Fix it so that you can turn the engine by twisting the distributor rotor? Every ft/lb of torque required to turn the engine is a loss of 1.25Hp at the prop. It was $30 for the chemicals and some time to apply the coatings. Well worth an experiment. The product is advertised to actually lower resistance at higher surface velocities. Maybe it will. Maybe it won't. Haven't figured out how to do a direct comparison without a dyno and several more engines. The first test will be to see if it actually stays on under use. If it is resilient enough to hold up under extended use, maybe it could make a ton of rotor housings serviceable again?
I'm going to use the distributor's crank to drive a small PM generator as a backup source for one of the ignition control units. I expect the DFL to lower the load requirements on the driving gear.
