> Screamin, How does the car hook from a slow roll on the bottle? How do you like the 3.73’s with the t56? I have a moser 12 bolt in my car now with 4.11’s and I was thinking about going to 3.73’s. Also, do you have a problem with the torque arm bolts loosening up on the diff. mount?

I don’t have the nitrous on the car currently as I need to buy a new nitrous plate for my 90mm intake. I will say that I love the 3.73’s. The car hooks awesome from pretty much any roll (haven’t done any launches yet) and I can to 140 mph in 4th so the races don’t end early.

I always locktight the crap out of those bolts and they haven’t loosened that I know of. I will say that it’s a shitty design and someone at Moser was smoking crack when they thought that was a good idea.

Also, the car has a stock torque arm for now because mine broke from the same wheel hop that broke the ring and pinion.
