Ok well i am wondering what the limits on my Getrag trany is? I now have all the parts to start my twin charged set up... I will only be pushing about 10-12psi into the engine with it all stock for a bit then im putting in an all forged bottom end so i am wondering what the limit on my trany is? if any one even knows?

Right now the trany has the following

- 5,000kms on it (310miles) on it
- Aluminum Fly wheel
- Quaife LSD
- Stage 3 clutch

do you think this will be enough to hold say 350-400lbs of torque? or am i going to have the fun task of pulling this trany out soon to find a replacement? Because once the engine is built i am going to have the boost turned up to 20psi for street and 25psi for track...
