OK, great thats exactly what I wanted to know! Thanks

 

Well if I was going to pull with a 2 wheel drive I would:

Block the rear suspension.
Get some really aggressive rear tires and lower their pressure to the 30-40lbs mark.
Make sure to start off without spinning the wheels because you are going to need all the traction you can get.

Go with a real high hitch height.

 

Firstly you said in your first post you didnt want to die at 100 ft and look stupid. I am telling you without a doubt that you will look stupid trying to pull a sled with a 2wd truck. I have seen it happen to guys that tighten up and lose their front drive shaft. They even have the sled moving and cant go any farther. I have seen guys vacum lock not work when locking in before hooking up(they didnt know they werent locked in) and they just sit there and dont move a foot or so.

Secondly dont get mad at us for trying to save you from looking stupid-which were your words. I tried to be nice about it and said maybe 50 foot but I dont think you will go 1 foot because I have seen it first hand.

Lastly, there is a diesel performance guy here in WV that is one of the best small performance guys anywhere. He puts out some awesome pulling trucks. He tried pulling a 2wd about 15 years ago and never moved the sled 1 foot. He said it was the most embarassing thing he ever did - in front of 4,000 people.

The problem is this. You want to build boost at the line to get the sled to break its friction but to do that you have to get up to at least 1500-1800 RPM. If you do that with the 2wd you will break your traction and spin out.
If you try to ease into the sled to keep traction there is not enough force at your wheels to break the friction of the sled.

Again I said what I have said not out of opinion but from seeing it.

 

So I guess only a gassers can pull with just 2wd

 

Jesse,
Yes we know 2wd's can pull but their tires are about 4' tall tractor tires.

 

If 2 wd TRUCKS could pull a sled and do good at it then why is there not any pulling?

 

My opinion is that you wont need to great of a clutch, because you will spin way before you slip your clutch unless you are in 5th gear or something. I dont know what kind of sled you have, but if it is set up for 4wd diesels; the others are right. You wont go far at all. Not trying to keep you from doing it; just dont expect too much. Heck; at my county fair with my stock torque converter I only pulled 160ft or so, and I was still spinning the tires at the end. I feel I would do much better now because I am getting the power to the ground, but Sleds are HEAVY if they are set up how they are supposed to be, and you pretty much need a 4wd to go far at all. Good luck

I wasent trying to sound like a complete jerk, I was just annoyed with the comments and the stupid little laughing smilies is all. I dont like it when folks completly put down an idea without justifying it. N yeah I was kind of thinkin of those really hopped up streached out 2 wheel gasser/alcohol 4 foot tire pullers. This is just out of mere curiousity to see just what might happen, mainly because I love the sound and smoke cloud of a cummins pullin a sled, n the only possibly competitve 4x4 Ive got is my 92 Ford IDI that im building up to be a good street class puller.

I guess I kind of got this idea from a combination of a locked rear dually with my monster grabber old school bias tires. Id just dosent seem to be a 2 far
fetched of an idea.

N what I meant by the lookin stupid deal was acctually goin down the track, n blasting a rear, or driveshaft cause of wheel hop. Im not afraid of not moving the sled, cause I know on pavement with the Mods in mind Im not afraid of taking on a D-max, powerchoke, or a modded 12, er 24 valve.

But I do thank everyone for their input, ya just never know till ya try!

 

Here's what happens when your transfer case breaks 25' into the run and only 2wd works:

Total pull, 43ft.

lol, sweet! I love a good pullin video with some breakage.

 

Then you'll like this one too:


Long story short, I retired.
brnaodn.

 

ouch! hehehe, I like that "he has loops for a reason."

 

i watch 3 or 4 2wd trucks hook each year, i have never seen one make it 50 feet. and some how they get traction and smoke the clutch half of the time.

 

If the sled is still at the weight, and set up for the S-10, and Blazers, I wouldn't worry about adding another thing. You will pull the thing all the way home. However, if you are in a diesel class, and they don't offer a two wheel drive class...that is when it will be difficult to get started. I have seen some really neat two wheel drive pulls, maybe even more exciting than diesel 4X4 pulls. The front end lifts up off the ground, and they ride on two wheels all the way down the track, moving at a pretty good clip. Ok so that still isn't as cool as the coal rolling outa the stacks of the full modified truck pullers. It is neat just the same.
