Actually, my buddy has snapped mosier 31 splines with about the same tq I have... I'm planning on going with strange, but just deciding between 31 and 33 spline.
It's a thread for feedback, If you feel the need to type "hahaha" everytime you post, feel free to skip over my threads.
I am on my third set of Strange 31 spline axles. Now, that statement needs some more info:
The first two sets bent while launching on spray at about 550 HP and 10.50 ET Streets last year.
Strange investigated and found that those 2 sets had been part of an earlier group of axles that have since had the heat treating process modified.
As for set #3, I made 17 passes last Saturday and they survived nicely.
This years mods include a Whipple and spray. Probably around 675HP or 700HP at launch, with clutch drops ranging from 4000 to 6000 RPMS and 60ft = 1.57, 10.00 X 15 X 26 ET Drags.
So, the Strange 31 spline axles should do you just fine.
