How fast are you going with a stock planetary

Good to know I would prefer a steel one also would be a lot stronger than the alum , when I get mine apart if it has an alum one I will swap it out for the steel one .

Have you used the steel one and how fast have you been and what's the most anyone else has gone with a stock planet

The load experienced by the planetary is a function of, weight of the car, torque produced by the engine, amount of traction and other factors. Speed (how fast someone runs) is a relative term. If you run 11 seconds in a 2500 lb car the load on the planetary is totally different than the load experienced driving a 3500 lb car (all other factors equal). I know nothing about transmissions (well, maybe a little) but you'll more details to get a better answer.
