with the stock pressure rise system and the largest 2/4 servo usually 400 ft lbs is the limit.this is on a brand new unit subject to such torque.an old in service unit with glazed friction materials,leaky circuits,worn accumulator pins,hard rubber etc. will usually roll over and die when mods are done and the power level is high.besides jks dislike for the ratio in rotating speed the 2/3 clutch circuit is taxed at high rpm . the fluids inability to apply the clutch at high drum speeds causes friction burnup as well as a small area behind the apply piston to compress the clutch pack .we do use them in high power applications but only after reengineering circuits and designing and manufacturing the internal components it needs to survive.http://www.ckperformance.com/resourc...SMISSIONS.html http://www.ckperformance.com/resourc...OMPONENTS.html
