You dont. If you had you'd stop theoretizing, and saying whats possible, and what's not. You'd stop worrying about MASSIVE STRESSES, cause, it is all OK with the drivetrain. The only thing that needs to be replaced is the clutch. The rest is OK, unless you dont run slicks and LSD... But why am I writing this? You already know these things, don't you? That is a load of bus**t. The standard drivetrain is a heap of junk and will twist diff transfer casings and that kind of thing if launched at that high revs on a sticky track.. Dont launch that high or ure drivetrain will not handle it!!
