My question-

 

You say that a bone stock set of cylds will make 75hp.. How much HP will the 1k yield?

All numbers are on alcohol, gas engines usually are about 3-4 hp less.

Pro port about 80-85hp have seen 87 once

Extreme 90-95hp

Outlaw 95-100hp I have seen 102 with this engine but I had bigger reed cages

I have built and dynoed all these with 4mm and they are about 4-5 more hp.

These numbers are always with Grand River Pipes, stock reed cages, 39 PWK's Dyna ignition with my program, and my head cut. Sometimes the cases are ported, doesent do much. Always a stock flywheel. And some secret squirrel shit that you don't get unless you pay for it!
