Theoretical ¼ mile times

SubVet · #1 Mon, June 20th, 2011, 10:02 AM

Ok, I am sure this question has been asked a 1000 times (I’ve tried searching but couldn’t find anything). I was wondering what type of ¼ mile times would my truck run? I have no intentions of running it, just curious.

My truck: 99 ecsb 4x4, 4r100, late 99 motor, early 99 suspension, PHP FU chip, 4” exhaust, Airaid intake, AIH delete, 05 front end, 265/75/16 tires, wicked wheel, deleted pedestal, ebpv delete, 93K, HPX, 3.73

Assume running it on the race tune

Funny you asked this just now.

I ran on the strip Friday night. Although I didn't run a "stock" tune down the strip, I did run one that should be in the 60-80 HP range and it did a 16.7 at 84 MPH. However, that's in a regular cab 2wd truck with a lot of off-the-line tire spin....your results will vary with a 4x4 Supercab.

Slicks and a locker. The factory limited slip is just that...."limited".

I betcha he would be in the mid to low 15's with a boosted launch.....that 60' time is what really sets the pace for the rest of the run.

A stock-tuned regular cab with a standard launch should be in the 76 MPH range at the 1/4.

A crewcab shortbox would be in the 73 MPH area.

A supercab would be somewhere in the middle.

Your truck should be in the 83-85 MPH range. ET depends on traction off the line in that case.

It seems with my truck (not sure if the description is correct, added wicked wheel, PHP custom tunes, and 6637 filter) a boosted launch isn't as quick as punching it off the line. With a boosted launch, it seems like it takes longer/higher rpms to change gears. When punching it off the line, the gears just fall through nice and smooth. I can build about 10psi on a boosted launch before breaking traction.

my wife went 15.9 at 82 mph in our truck. track elv 500 ft 80^ day. This was 8 yrs ago. She would powerbrake into boost and launch in 4wd then switch to 2wd. I told her after 3 passes....that be enuff or we wont be able to tow our low 12 sec mustang home(could drive it but no AC and cruz control for 1100 mi is a pain lol)
