Drag racing cv question

[DAT392]

Hopefully going out to calder park to give the old girl a squirt on the 4th of december.Last time we took her out the car went 11.6 with easy launches at a 118 mph bouncing off the rev limiter as I had 444 in the rear end and factory halfshafts.On the forth pass I gave her a decent stall,front wheel off the ground as traction was great, but in the process broke the standard uni halfshafts as can be expected.Ok, I got excited, its a rush.Now I have changed the diff gears to 3.7 as the engine makes power to 5800rpm and convertor to correct size and put those wolf creek things.On street tyres theres absolutely no traction with the peddle down!My main concern is grip,cause thats when things break.Has anybody really loaded up these wolf creek cvs in track conditions.The owner of wolf creek stated he,d guarentee up to 400hp and Ive got a little more.I no the rally guys have smashed them but I"m talking road conditions.Thanks
