on nos (250) shifting at 6500 (light) 6800
6.912 et
101.026 mph

what i am getting at is .72 on 250hp is not worth it, normally we get a sec out of nos. and the time to mph does not add up to me

but here is the tickets

HP

.068 reaction
1.60 60ft
4.895 330ft

7.63 et
89.5 mph

NOS

.043 reaction
1.563 60ft

6.912 et
101.026 mph

looking at some changes

more tire maybe a 28x10 or 10.5
drag shocks on the rear (50/50)

was wondering about front limiters or something because car gets on the rear hard.

what tire i can get without notching frame on 8" rim and on a 10" rim

Help Dusty, malibuick and everyone else!!!!!!!

I'd put it on a 28x10.5 on an 8 inch wheel. A 10" wheel will stick out of the fender without a frame notch.

If the shocks are worn in front you need a stiffer front shock like a 60/40.

You said it's getting back on the tire hard. You mean it's standing up?

What does it weigh?

You picked up 12mph from the n2o which doesn't sound bad. 89mph sounds weak for all motor to begin with though like the cam or converter is off. Timing or jetting off that much?

Just looking at it on paper. You say it needs suspension help but also say it's getting back to hard on the tire. If it's squating, launching then spinning it may need stiffer shocks in the back or the stock springs could be worn. A new coil-over type spring can help. If it's not spinning it may just be down on power which is why the 60' and other times are off. I'd think that motor should run mid 90's easily.
