Best 2WD Launch Method

[WHITESSTOWPIG]

I couldnt find a thread on this but I have experimented quite a bit on the best way to launch these trucks with interesting results.It takes some time to find the right method for each truck but here are my findings atleast pertaining to these trucks in 2WD and a relatively stock form.There was only .1sec difference between going WOT from idle with traction controls on and having to feather the gas from idle with them all off but there was almost full half second difference between OEM Continental All Seasons and Grabber UHP Summer tires.Some conclusions are that good tires and the factory traction controls are hard to beat but hopefully this testing will prove useful to someone looking to learn more about getting the best acceleration times out of there truck on the street

 

Traction off with Stability off 3/4 throttle then WOT was fastest

 

Traction off with Stability off rolling into 10mph WOT was .1sec slower

 

Traction on with Tow Haul off WOT was .1sec slower

 

Traction on with Tow Haul on WOT was .2sec slower

 

1500rpm brake torque rolling into WOT was .2sec slower

 

Traction off with Stability off WOT on UHP tires was .5sec slower

 

Traction off with Stability off WOT on OEM tires was .9sec slower

 

Traction off with Tow Haul on spun hard all of 1st then bogged and upshifted early into 2nd

I appreciate your efforts on this! Traction on the street with all season tires is practically impossible with a RWD truck and any sort of power! There's only a couple ways to mechanically get faster:

 

1) better tires - think drag radials

2) traction device that manipulates downward force - like caltracs

 

With those two you should be able to hammer down and not lift at all. But, of course, there's many nanny settings in place that will either limit throttle opening, and, or, spark advance to keep you from getting full power. 

 

All these reasons were a big factor why I bought a 4wd

Spot on.4WD is an awesome thing to have since you can just lay into the converter and launch right from stall speed in 4hi then switch back to 2wd right after.This method is usually a half to a full second faster to 60mph in most cases and does allow a truck to be faster during most driving situations.The main penalty with 4WD is weight and drag on the motor which would slightly affect passing power.Its a give and take as with all things
