Re: BW4472 32 input shafts. All slots filled.
You need to examine your launch.
I can't stress enough that you cannot apply ALL of your torque at takeoff. Most launch with zero boost or a just a pound or two. NO REV limiters. Some guys are setting it up so they can smash it to the floor and boost is met and then engine cuts out and then it does it again...like a jackhammer.
Here's the best anaology a old hotrodder (Mr Neeley) told me. If you pull a chain, you can move a house. If you JERK a chain, you'll just break the chain.
Also, limit yourself to 190 to 195 pounds of WOT line pressure. Any more than that and your gonna flip the sprag or break hard parts on the 1-2 shift. If your burning up 2nd and your already running 190 psi line pressure at WOT, you need a special 2nd gear setup. It is a custom setup and actually makes it shift harder but you can run less line pressure because the TSA of the piston is bigger.
An 11 second truck shouldn't be breaking stuff. You need to examine your shift strategy. You will continue breaking stuff if you aren't using the accumulators or other techniques to firm shift I've seen. For example, some kits recommend leaving out the accumulator spring in the valvebody for firmest shift......absolutely not. Leave that sucker in there or use the springs they supply.
We thought about you over the last couple months. Your in our prayers.

I put the shaft in this afternoon. My shop is about 25 miles from where I live, so after I got it all together I drove it home. It hasn't even been started in a couple months so I just cruised home. I figure most of you guys know how hard it is to not beat on a turbo vehicle, but I was a good boy and didn't even do any boost launches !!
I am a little reluctant to beat on it for fear of breaking something, would like to drive and enjoy it a little. Yeah, right. I am sure tomorrow I will drive it pretty hard. The local track opens in a little over a month, I am hoping to get my bigger injectors and corresponding tuning done by then.
