T-56 Trans Capability
T-56 Trans Capability I'm almost 100% positive this has been covered already but my computer is messing up and I can't do a search.
Anyway, how much power can the t56 handle with a stock, or aftermarket, clutch before it takes a ****?
Sorry for the Newb questions but I'm asking for a friend. I have always went with an auto and the only thing I know about a 6-speed is how to drive it... Thanks guys!

The true word is it depends 
Are you launching on slicks or only driving it around on street tires? M/T ET Street drag radials are more violent on driveline parts than a bias ply slick.
In a full weight 3500lbs car they work to around 600rwhp before stuff starts breaking. Stock T56's have some flaws like alum 3/4 shift forks that bend, plastic parts that wear out, paper lined blocker rings that wear out, and other parts. Strength wise the stock 27 spline output shaft is usually replaced with a 30 or 31 spline shaft which makes it able to handle around 900rwhp+. Beyond that the gears themselves seem to be the weak link.

I'm asking for one of my friends. All he does (For Now) is street driving. He just bought his TA a few months ago so he's just gettin into it all. His clutch is already going out so I didn't know if something in the Trans would be next or what it could handle...
So he should be fine with H/C/I setup?
Should I have him look into the drill mod?

So many factors go into determining what a particular transmission can handle before something fails inside of it. Age, milage, previous abuse, type of clutch, functioning condition of the clutch, type and size of tire, weight of the vehicle, how it makes its torque and the driver themselves plays a big part of it.
Rule of thumb is about 600 flywheel horsepower for your average LS1 type T56 transmission. They can survive with more and be killed with less.
