Fluting the crankshaft is very important as well. It allows the mixture to be able to roll off the end of the crank without creating a lot of turbulence and fuel puddling in the bore of the crank.
The last process I incorporate that no one else does is crank turbo porting. Turboing the crank is the process of cutting the counter weight to form blades, similar to those found on a compressor wheel in a single stage turbine engine. The blades take the atomized mixture in the bottom of the case, compress it, and pressurize the intake ports so the fresh charge is always pressurized, atomized and suspended at the piston’s edge versus down inside the case. This process increases the fill compression percentage and decreases fill time allowing you to alter cylinder intake and exhaust port timing to maximize engine performance for any application.
