How about after welding and bracing of the case getting it shot peened. or something along those line. I would thing that would help with the cracks a little bit?

In my opinion any work that's done on the case to make it stronger is only going to be temporary unless you can find a way to take the load off the case or disperse it over a bigger area. The cases are pretty thin where they crack. The big thing we've found is that by welding gussets in there it minimizes the possibility of the case cracking and the pinion gear moving enough to damage the ring and pinion. When they're welded they will only crack, the gussets are strong enough to keep it from blowing apart and causing further damage.

Totally agree with you tony over the load being spread out over a bigger area. I would just think that once the case has been welded with the gussets as you say. I would think that shot peening the case would make it a lot stronger. The area that can develop surface cracks will be cut down by a large amount. The stock case casting is quite shitty to say the least

Yeah, lets be real, that car isn't making 1200whp.
The reality of it is that I wasn't breaking much last year running mid to low 9's on the 24.5" tire. This year i've cracked 2 cases and run consistent low 9's and high 8's on the 26" tire. I guess what i'm getting at is it doesn't make sense to compare results from cars that perform different.
If you want to compare to a Hot Rod car at that level, look at Chuck's car. He makes about 100-150 more hp than me, still less than 1200whp, and he breaks cases left and right.
If you're going fast, you're breaking the stock cases...

Only so much can be done with the stock bellhousing and currently available gears, thats why PPG opted for an innovative gearset design to help alleviate the pressures on the case without the need to modify(and possibly damage/weaken) the case in any way.

I think a big problem with welding is when its not done properly.

I disagree. There are about 2 ways that I have seen the bellhousing modified and no matter the heat that has been applied I have never seen a housing warp from welding. I have a bellhousing that Tony has welded up and I have one that I welded myself. No distortion at all and I'm not the best welder either. lol
Just because you haven't seen them warp doesn't mean it doesn't happen. Certain areas in the bell housing do warp and get out of round when welding..

On my friends gtir we strengthed the endcase, it broke at the bellhousing.
the big issue with gtirs that i need to resolve is stopping the cases breaking, they pretty much end up with the whole bearing seat end blowing off them. So far we have tried, cryo, polishing, de-seaming, external bracing, and now i've machined a cuff,
We're yet to try all of them together..lol..so heres hoping.
be interesting to see what you guys end up doing

Soon, very soon.
Since we are talking about bracing what's everyone using for a brace?
I have used 1/2 plate 6061-T0 AL then heat treat the piece and the whole bellhousing.

yeah, post it on up so the rest of h-t can just copy it. Just how trannies are being built these days, just get your hands on someone elses and copy it. Why do the hard work when you can just copy someone else who already has done it for you.
Use your imagination and figure out what has to be done to fix the problem at hand.
