The formula for HP is Torque x RPM/5252. By substitution that makes Torque = HP * 5252/RPM. It doesn't seem to mention brand name of the engine, so you should be able to compare the torque of the Jabaru to the torque of the Corviar engine directly, unless the Jab is a GEARED PSRU, in which case you take can that into account. Of course, that's assuming the same prop on both. If I'm wrong, please correct me. -- Glenn Martin, KR2 N1333A, Biloxi, MS
