My C2500 RCLB 434rwhp/480tq 5200lbs on street tires went 12.34 @ 112mph - Tranny was very hot and slipping in 3rd. Running 10psi

 

2.0
but it put down 535ish TQ

it never broke into the 1.x on the 60' no matter what i did

 

My truck makes 402hp and runs 12.6... Hope this helps lol

 

Should be in the high 11's.

 

Sooo any times ?

 

No times yet.. Las Vegas Motor Speedway only does test/tune for street vehicles like once a month. The next one is on friday. I think I am going to get some brand new drag radials from a member on here and see what the truck will do. I wish I had my 4.11's back in the truck. But looks like I will have to run with 3.42's. I don't even think I will get out of second gear in the 1/4 mile. I will post time slips friday night

 

449rwhp @ 3,525 I went 11.45 @ 118mph with a 1.59 60'

347ci
4L80E with 4,500rpm verter
4.56 gear and 30" tall drag radial

 

Those are some good numbers. I'm about 1000lbs heavier than you, 3.42 gear, and 3200 converter. I'm interested to see where my 60' will be with these new drag radials. I have done ZERO work to the suspension except for the lowering kit . So I'm hoping to be somewhere around 1.85 60'. Or am I expecting too much?

 

First time out, weighed 3900, 3200rpm verter, 3.73, 26" drag radial 410rrhp went 12.33@109 with a best of 1.89 60'..

 

I'm going to shoot for 12.5 with a 1.90 60' and see what I can accomplish. Thanks for your numbers man. I enjoy listening to your truck run. Sounds awesome with that big *** cam in there
