Help guess my 1/4 mile time?

[2005LLY]

Alright guys.. My stock torsion bar keys should be in next week so I should finally be able to launch my truck good. My best 60ft time is 1.9 and a 8.5 at 83mph in the 1/8th mile.. My truck dyno'd 520.5 hp, and 1115 ft lbs, weighed it today at 6900 with a half tank of fuel, so with me in it we are just over 7100lbs.. Any idea what my truck will run in the 1/4 with a good 1.6-1.8 60ft time? I really want 12s...

13.1 around a 100

On the calculator it says 12.9 @ 103

I agree

So you think I'll break into the 12s??? Its a hour and half drive to Topeka from where I live and next weekend is there last weekend.. I have some nitrous to throw at it but I'd really like that fuel only 12 slip....

Truck has 20x10 bmf with 305/50/20 nitto 420s.. I plan on 30 in the front and 25 in the rear?

With a good 60', you'll get a 12 second slip:thumb:

You are going to need a 1.75 60' or better

I found a app on android that can tell you your 0-60 and 1/4 mile.Goes by GPS.
You can try that .Believe I went to search quarter mile time and it is called Ulysses .
Shows my mph dead on.

I had a terrible 60' at 2.02 and went 13.17 at 104.8.

Screw calculators and dynos... It's going to run what its going to run.

I went 12.9 @103 with a similar setup to you. I'd estimate my HP was around 520. I had a 7100 lb race weight, and a low 1.8 60'. You should be in the 12s if you can get a good launch:thumb:

13.30 @ 102

13.30s, maybe 100mph.

What could I do to shed some weight to help get me there?

hitch, bumper, tailgate, back seat, passenger seat, battery, tow hooks...
