Starting torque / rpm fr ZDZ80 RV-J
I was hoping somebody could give me a ballpark on how much torque/rpm is needed to start the Super-80; I'm putting together an onboard starter, and I'm pretty confident that I'll be able to put together something that can turn then engine over, but I'd like to avoid excessive stress on the engine like one might see with a standard field starter for this size engine (e.g. a Megatron) that seem to cran at a much higher RPM than you'd get with a straight up hand start. I really don't have the means to measure these values myself, and was hoping there might be some factory numbers, or even some educated guesses from other users.
Thanks in advance,
