You must not have watched these trucks pull. Next time your at truck pull look at where the weights are at, they put them all on the back. How does a 2wd get taken off by traction right over the back tires. If you don't have enough weight over the back tires your probably going to have a hard time getting taken off probably I'd imagine what a lot of you have seen. Yeah your probably going to have to stiffin up points in the frame so when the front end comes up in the air the frame will be able withstand that kind of weight hanging out over the front. I don't understand how somebody can say a diesel won't be able to run like a 2wd gasser. The only difference is the diesel has a little more weight on the front because of the engine. The 2wd guys still have to hang weight on the gas trucks so I'm not really sure on why someone would think that. There probably is some more guessing to the right set-up on a 2wd how hard the track is biting has a lot to do with where you distribute your weight. But that won't change but probably a max of 200 to 300 lbs depending on track conditions.

 

4 wheel drive helps a little bit too.

 

I knew some people would think I'm crazy. Next time your around a local truck pull ask the gas truck pulling guys which one will pull farther a 2wd or a 4wd. When the 2wd class starts if its close to the same hp class they will either change gearing so the weight transfer on the sled is faster or add more weight. You will be suprised by their answer I guarantee it.

 

Well gas trucks might be a different story considering they don't have as much torque to even turn the wheels. So maybe it's easier for the gassers to run in 2wd.

 

Be sarcastic all you want I don't care. I'm only telling you the truth. Believe what you want. There is just some people that you can't get through too.

 

I guess I just don't understand the concept.

Is it kinda like a fart can on a civic? Or stickers add 20hp?

 

I'm just messing with ya.


Nice truck by the way!

 

Yeah your right its probably not simple. But if you have been around it its not that difficult either.

 

Man this is what we need on this site. Discussions about pulling, this site has just seem to be dead here lately.

 

diesels will be able to run with the mod 2wd gas trucks out there but its gonna take alot of money and R&D in transmission/OD units because they lack the rpm's

a gas motor turning 8-10k spinning those big ol' cut tractor tires is gonna go somewhere...when you only have 5k rpms...maybe 6 if you really put some money into the motor...you are gonna need a hell of a tranny/OD unit that can transfer the power and get some wheelspeed.

i know it can be done...i mean if you take a 800-900hp big block off the front 2wd pulling truck, and replaced it with a 800-900hp cummins...its not gonna do much without some serious drivetrain re-working tho.

 

There is much more to 2wd pulling trucks mainly getting the weight figured out. I have been around 2wd pullilng trucks for over 10 years the crew i ran with had 5 different sets of tires for different track coniditions and a little as 25lbs can mean winning a pull or comming in 15'back there is alot to it that no one gets to see. Different tires required different weight placement. plus steering with the rear tires isnt to easy.

 

rules all differ from state to state, but the 4wd gas street class that my brother went to in NH and a few I saw in VT was just about anything with a body over some tires. most of the trucks never saw a road.

Our Maine state pulls only have 4wd diesels that are a pro class, they are all street trucks with a temporary solid rear and chains up front.

So the truck will still be street class, it just wont be driving to the pull.

How much frame work is needed anyways? Most gassers arent a custome frame are they? if the truck was for pulling only in a street class with minimun $.

Also I read in the VT rules that 2wd can pull in a 4wd class and they state "have fun trying" well if we can say that "set up 2wd truck" will outpull a 4wd. why not do it and tick off everyone when your on two wheels outpulling the big trucks.

 

I can't disagree with you there. The guys we use to watch only had two sets of tires though. A set of AT's and a set of MT's.

 

Well i should have stated i used to run with a professional pulling team the run Cepeks, cut at different depths. Sorry!

 

Yeah cepeks is an awesome tire. The guys we use to watch were just around 600 to 700 hp and the rules didn't allow cut tires.
