Oil pump to rev counter ratio
« on: 05.09. 2021 09:40 »
One thought, what is the ratio for an oil pump driven rev counter on an A10 Super Rocket engine? Mine is marked 4:1. Is this correct or should it be 3:1.
Thanks

Thanks for the confirmation. Mine must be wrong. would expect it to read low then.

OOPs, should be indicating higher revs, and probably explains my revs to speed discrepancies.
Just need to devide the readout by 3/4. Probably a recalibration for the winter months
