I tested (a not very controlled test) a stock CY26cc engine with the stock exhaust can so far, and I am getting about 2.2hp @ abut 11,000RPM, which is about right for the stock G260 with a can. I have a lot to learn yet about this dyno, and still have to get the engine temp and EGT set up to control those factors better. It might take me half the summer to get the best graphs I can get.
