The engine is for a snowmobile, which has a CVT - primary & secondary clutches, so it will run at a relatively constant RPM under power (around 800cc). So it doesn't need to have a really wide power band at all.
So is port sizing and timing normally done experimentally and from experience, or...
correction: Yes, it was meant to read 0.2 hp/cc. I'm working on an 800cc inline twin two-stroke, and looking at ~170 hp.
What do you guys know about squish band angles? The squish angle of the head should be roughly 1-2 degrees more than the dome angle of the piston, right? How critical is...
I'm looking at around 2 hp/cc.
But I'm trying to figure out if the port area I have is enough to provide the flow required to produce this amount of power.
In contrast, if the port area is too large, the port velocity will be too low to fill the cylinders in the amount of time they are open...
I am looking for any equations or "rules of thumb" for calculating theoretical 2-stroke engine horsepower. I don't have access to a 2-stroke engine simulation program. I want to know the max power I can squeeze out of this engine, given the engine's bore & stroke, a tuned pipe, and playing...
