Launching in 4WD

[Frans96ss]

how bad is it to launch in 4wd then kit it out right after u launch?

[alldiesels]

you can flip the switch but it WILL NOT come out of 4x4 until you let all the way out on the gas.

Knowing my luck, I would flip the knob the wrong way to 4 LOW! :doh:




.............. Would it actually try to kick into 4 LOW at high speed? I hope not! :bang (Sometimes I wish my truck is smarter than I am. :huh:: )

[SSpeeDEMONSS]

no, it wouldnt switch. i believe it has to be in park or neutral with your foot on the brake to engage into 4 low. also, it wont switch back to 2wd until your foot is out of the gas for a few seconds. so, just launch in 4 and stay in it, dont worry about switching back until you're shuttin down at the end of the run(letting off and braking).

i heard it was horrible for the tranny to launch in 4wd?.... i dont wanna blow it up..... unless im told otherwise by some people on here

[wideopen]

A lot of people launch in 4-wheel Drive. I'm sure hard on the tranny ..but then again so is Drag Racing..

With My 7.3 I would boost up to about 12-13 pounds of boost before I left the Line..in 4-high

[alldiesels]

i have probably made over 500 4wd launches in my truck and that is no exaduration, i don't know if i am lucky or what but no problems yet

it's hard on the trans but it can take it. as long as you dont sit there boosted for too long, because then the heat will ruin your trans. also, dont let it hop in 4wd, then you might break something else.

Garrett

[alldiesels]

yes a 4wd hop is a lil scarry, i have done it a few times i don't like it lol

[Frans96ss]

ok cool.....i ordered exhuast for my truck today ..... ill prob run it next week or so....

[mikehalseyjr]

Do like I did. Play it safe and blow it up safely then explain to your wife that the truck is retarded. Then rebuild your tranny real strong so it won't again. Explain to her that you didn't want it to do it again if she was driving. Course mine calls BS on it and says that I just want to make it stronger for more power. Can't argue with that one.

You are looking at about 2 LARGE for a tranny from Suncoast... :rockwoot:

[mikehalseyjr]

Plan on $2,100 in parts, if you dont get the xtra filter.

And $600-$1,000 to install the parts.

It is a job!!! Trust me.

Then get SunCoast tranny files incorporated in your tunes.

ive done 2 4x4 launchs since the SCT and im not doing it again till i get my puking issues resolved, or actually till i plan a date to take it into FOMOCO and have them take a look at it LOL

[FxSTBi06]

is there a speed limiter on the 'o6 in 4wd hi? I ran my truck at the track in 4 hi and ran a 20.01... pissed me off.. was in the gas the entire time, truck just wouldn't go.
thanks.

[iracemx6]

That 20sec. run must be ALL stock because there is no way you run that slow with a programer.
If you are stock don't lock it because spinning will not be a problem.

[SSpeeDEMONSS]

you say if its stock dont run in 4wd? there is no spinning issues? i have 35's with my stock 3.73's and a spool. if i spool before a launch i will spin the tires. launching in 4wd at like 20psi is bad a**. i would say id have to be like .3-.5 secs faster in the 1/4 at least.

[Power Stroke]

i launch in 4x4 all the time. its the only way to get quick ETs.

[iracemx6]

I was saying that something is wrong if he only run a 20.01 in the 1/4.Are you saying you can spin the tires in 4wheel drive STOCK?
I keep hearing people say they are spooling up to 20psi on launch,but I can't get my truck past 10-12 before it will push me through the lights.

to build boost properly get on the brakes as hard as possible and gradually push the pedal down. I can get my truck to 23 psi of boost launching by gradually building it while letting off the brakes little by little.

[jimmer818]

Nice I have been wodering about launching in 4WD, I got to try it sometime.

no no no, it will easily spin in 2wd. in 4wd, i go to 20psi before launching. no wheelspin and only one problem with wheel hop(but it was wet). and as onebadsixoh said, you have to ease into it, not go WOT.

will try it here again soon and the truck was fixed by ford, they gave us 2 new heads, gaskets, bolts, and a new #3 injector!
