well to be fair, I was thinknig transmission for some reason. You are correct a LT230 wont have the rotating mass of a flywheel. Nevermind

But just for the record, was not thinking about reciprocating anything. Clutch/flywheel failures can pretty much cut the vehicle in half.

Yeah I was kidding about it exploding. I'll update my build thread sometime, but I had my coupler shaft made by Novak and can spin up the motor/lt230 assembly up to almost 10,000 rpm with no vibes so I'm feeling pretty good about it all working as planned.

Sorry for the hijack. Maybe I can keep it on track for LT230 education though - has anyone ever added a high/low ratio switch to an LT230 without replacing the front housing? I'll probably just detect it in software but hardware wouldn't be a bad idea either.

I say all this with a big smile, you know Quite frankly I don't know for sure. Sorry Dave, didn't mean to imply that you were saying anything about reciprocating assemblies - I just mentioned them because they are the types of assemblies that one really worries about with high rpms (at least with rpms far below what would destroy a flywheel)

DB is correct that there is a lot of energy stored in rotating assemblies.

I'd feel pretty bad if anyone got hurt in the end

You're probably right, with the only concern the electric motor can spin up faster than an internal combustion engine can which could add a lot of stress in a much shorter time.
