Question about nitrous and 4.10's!

[Cobra2WS6]

I have a 99 WS6 with K&N, Lid, Ported TB, Comp Cam 224/230 .582/.591 114LSA, LT Headers, No cats, Flowmastercatback, 4.10 gears. First off I would like to know what can i expect approximatly in the 1/4 and MPH from the car with those mods and a 150 shot? Would 10's be possible? Also is a 150 shot even possible to finish the 1/4 in 4th gear? What size tire would I need? Thanks alot! Jon

to finish in 4th on the bottle with 4.10 gears, you would need at least a 28" tall tire. yes, tens are plenty possible.

I forgot to mention my car is lowered 2", will I be able to fit a 28" tire under my car?

[mrr23]

doubt it.

Dam so I'm kinda screwed... Anyone know the max mph 4th gear will go to with a 26" tire and 4.10's?

[mrr23]

i'm assuming 4th to 1:1 guessing you have a manual car.

rpms = mph x gr x 336 / td

rpms = engine rpms
mph = mph
gr = gear ratio
336 = magic number to get formula to work
td = tire diameter

6358 = 120 x 4.10 x 336 / 26"
