Yeah I hear 6-7 lbs is the max boost you want on stock internals. And with a turbo, not sure on the supercharger, towing can lead to some scary EGT's. The sharadon performance tranny is supposed to hold somewhere in the 800 hp range (it's an upgraded 545rfe); the stock trans will most likely die anywhere over 325 rwhp. Even with that trans though, don't plan on doing lots of full throttle downshifts over 40 mph, as it will shift into 2nd prime, which isn't able to hold that much power and will die out after multiple wot downshifts. Most people with high horsepower trucks only go wot from a dead stop to prevent tranny destruction.

The turbo Ram'shave the only "lasting" transmissions. We've had 1 trans failure on our Turbo trucks and that's because the TCM fried out and left the trans with 0 line pressure in city driving. That's the transmission that Sharadon has for BlueTurboHemi. They have his whole truck and found the TCM issue.
I have a stock trans and I'm putting down 492 rwhp and 575 rwtq at only 9 psi of boost. Coltsteele has a stock transmission and has run his at 18 psi of boost. (we both have built engines).
The reason the turbo trans last is because turbo's build power based off load. During downshifts, yourengine goes to a brief 0 load state. Then the downshift occurs and the clutches engage and load picks up. That keeps crap loads of power running through the trans during the clutch engagements of 2nd prime and such. That's what has really kept the trans alive on the turbo trucks. Now stroke it, put some heads on and a cam in along with a turbo then you might destruct the trans. The key is to not have enough n/a power to nail the trans during shifts. Build the base 5.7 strong as crap, then push 100's of hp through it with f/i.
The stock 1st, 2nd, 3rd gear clutches are pretty strong.
