Diesel fuel has more BTU's, and it burns more efficiently than gas. Compression combustion motors. Low RPM, lots of grunt. Generally much more stroke on the crank. But newer modern diesels are increasing HP, as it produces less harmful gasses and emissions. But that discussion is for another thread and a different day. Lol
We need someone to put a supercharger on a chainsaw. Lol. Forced induction. See if the head can stay together.
Jason's saws produce wildly crazy power. Absolutely amazing if you have never felt it. I am super happy with my 440 that he built. More than I will really ever need.
All of the guys who build and sell ported saws here are truly master engine builders. Gotta respect their work and diligence to their trade.
