Hi all
We are having great fun on our snowmobiles this year but I was having trouble getting the speed I thought I should and reached out to a facebook group and they got me chasing RPM and it turns out my tach was junk. Found a better one and I am now in test mode. I am getting 6000rpm on the engine and I thought I was getting 6800rpm.
My question is what limits RPM on these engines and is it possible to get more rpms out of this engine?
Engine is a Pro Point 208 from Princess auto in Canada. It apear to be a Ducar motor.
NR Racing cam 280-0611: Rated as a "Good Torque Cam w/ excellent power. 7500 RPM"
NR Racing bored .625 Honda carb
cromo push rods
reinforced rockers
26lbs springs
billet connecting rod
thinner head gasket Thickness: .009"
Some mild head work. Took off a few thousands, ported and polished, lapped the valves.
