Blown 346 Posted May 18, 2018 Report Share Posted May 18, 2018 Finally got my truck back after a month of having the trans built and getting a custom Billet input shaft made. Anywhere the trans builder looked the shafts were rated to 1000HP at the flywheel. My truck makes 1010 on 14 psi. $3,400 later after having the entire trans re done and built for the track, I hope I dont have this issue again. Snapped clean off without even a burr.

Blown 346 Posted May 18, 2018 Author Report Share Posted May 18, 2018 That wasnt off a launch either. The truck just hit 3rd gear and about a second later heard a loud snap. Im worried when it goes to the track and hope the new one doesnt break. Quote Link to comment Share on other sites More sharing options...
EXGM Posted May 18, 2018 Report Share Posted May 18, 2018 Hopefully the new one was heat treated to harden it! Quote Link to comment Share on other sites More sharing options...
Rholston Posted May 18, 2018 Report Share Posted May 18, 2018 Thats actually really impressive to round it out like that and scary at the same time Quote Link to comment Share on other sites More sharing options...

PaulitoIntimidatorSS Posted May 18, 2018 Report Share Posted May 18, 2018 Holy crap!!!!! that looks like it was rounded off on purpose lol. Best of luck with the new one, should have had two made since its custom just in case. Quote Link to comment Share on other sites More sharing options...
Blown 346 Posted May 18, 2018 Author Report Share Posted May 18, 2018 I just found one that can handle over 1500HP. So the truck goes back to the shop for them to install this one instead of the 1000HP one I have now. Pisses me off. Quote Link to comment Share on other sites More sharing options...
someotherguy Posted May 19, 2018 Report Share Posted May 19, 2018 I'm no engineer or stress failure analyst or anything of the kind... But it doesn't seem terribly coincidental that it failed where it did. Maybe it's a weakness inherent in the spot where it's cut down for what, a snap ring, or...?

Blown 346 Posted May 19, 2018 Author Report Share Posted May 19, 2018 This was the stock one,lol. The builder who said he built the trans (I wont say names as he is known here) the old owner spent $5,000 on it to have the best of the best and he only got a shift kit put into it. Input shafts almost always break at this point due to where the pump and convertor meet. Quote Link to comment Share on other sites More sharing options...
