I had my auto rebuilt before I boosted. Seems to be ok (I guess I'm paranoid ) I'm boosting 10psi daily (intill that POS manifold started givin me crap) I don't think there really is a limit as long as you baby the trans.

I'm not aware of anyone who's blown an ATX tranny in our cars. (Other than exploding the diff or brake-torquing it to death.) Build your car up to 800hp and let us know.

With a high energy rebuild, limited slip, shift kit, and all the upgrades it should hold to about 400 crank HP.
The clutch hubs are weak and will probably shatter with anything more than that put through it. Modifiying the pump and kicking up the pressure more helps as well. There are alot of Upgrades recently released for the A604.
