How hard can I leave on this setup? I ran a 10.42 at nearly 135 yesterday, but I left very soft (1.63 60') and didn't go WOT until late 2nd gear. It ran 105 mph in the 1/8. So I picked up 30 mph on the big end, which seems like alot but I suppose thats what happens when you don't give it full throttle the whole time. I am concerned about breaking the trans or rear end on launch. Its a Strange 12 bolt with a posi, I think 31 spline axles, etc. Pretty standard. The tranny is built but I know some guys have busted input shafts on them (4L60E). The kicker is the car is heavy, like 3800 lbs. with me in it. I have cut some 1.5x 60' times last year running mid 11's, and I think it will go 1.4x safely, I just need to know how to "limit" the launch power. Using my foot won't work to well.....
You'll never know until you step it up. Moser's are usually very stout. 31 spline is a little small. What do you figure your HP is on launch? Do you have someone handy to tow you home

Its a strange 12 bolt, can't remember if its 31 spline or 33. Gotta ask Billingsley.
I always trailer it, I'm too far to risk it. I just don't want to break it right now, spent a ton this year on it and would like to enjoy it some. I'd rather run mid 10's and have fun than run high 9's and be wrenching all the time.

I would guess I would be around 500 rwhp at launch if I really hit it. It comes up quick though.

I'd be causious. My 12 bolt snapped like a twig on launch. It was a strange 12 bolt posi and 33 spline axles w/4.30's. This was off the clutch at 5 grand on 27x9x15 slicks
The rear lasted 4 launches. It did do fairly well for the first 1400 street miles though.
By the way, this was with 370rwhp/365rwtq
Now I have a Moser 9" spool with 4.56 and 28x10x15 slicks and a lot more power.
