when did you start breaking stuff? Not really looking for the fat 3700pounds big power 800+whp cars with tall gears that run 11's.

Lighter track setup guy, I know alot of cars running low 10's But can't think of any running 9's? H/C type 5-600whp guys, when did you start breaking or found a twisting input or output shaft. And did you have to put a oil pump on for 1st gear tearing up ect. 1135-14x traps cutting low 1.3s be ok?

I would Definatly do a pump if your wanting to do 1.3s and 135-14x. I started breaking inputs and clusters at 700whp and 3700lbs. But ones that we tore down at just 550whp were Definatly showing signs of to much heat. I never did break an output but have now upgraded to the viper shaft. I was twisting splines in the slipyoke alot with the stock output. Trans has been holding up great this year with the viper shaft and pump at 770rwhp and 1.4 60s trapping 142@ 3650ish lbs

I've got customers running 9's with basically stock internals and no pump. I've got customers making over 1000 fwhp in street cars with the same thing but I don't recommend it.

In a 10 second car, you should be fine with stock shafts and gears providing your clutch is working properly. I would also suggest doing a pump system on it or at the very least run a super high quality fluid in it. Synergen makes some good stuff. I usually suggest 2 quarts of it and topped off with a full synthetic syncromesh type fluid.

In cars running 11's and slower, you won't need a pump. Just make sure the clutch is working good. In any performance type application, I always push for the simple things like billet shift keys, bronze fork pads, upgraded 3-4 shift fork and bronze isolator cup.
