I'm trying to figure out if getting my pistons skirts coated with anti friction materials will decrease negative torque and wear enough to be worth it in a cheap buildup.
I'm a big fan of trying to eliminate negative torque/friction in engines and even though the 350 i'm building will be a mild street engine i'm still thinking about coating the pistons. Gasoline costs are extreme here and if i can get some itty bitty less friction and some more power from it i might just go ahead and coat them.
I can have it done it locally so that's not a problem. What i would like to know is if any of you hardcore racers have tested it and seen any real gains in HP/TQ with coated piston skirts?
The engine combination will most likely be GM 300/330hp shortblock(service repl.) with stock cast dished pistons, E-tec 170 heads, 9:1 compression, rpm intake/cam, headers and a Holley 650DP.
