You can calculate it from the target head speed and the engine rpm. You usually target max torque RPM for the engine. You can also check the specs of the tuned pipe to find what the target is supposed to be.

You will need the main gear for the rappy 30. That will put you in the power band of that engine...

The main gear of the Raptor 30 it's 9,56 (86T/9T). It's correct?
Thanks.
