I realy dont see a problem with it, basicaly due to the MASSIVE breakage these guys are seeing each week. Plus this would allow them to throw different turbo setups on their truck and run in more classes or bigger classes if they want. I think its the way they should go, and would make for a more entertaining pulling season!!!!

I have only been to a few itpa hooks, but the ones i was at had no breakage in the 2.8 class maybe i was missing all the destruction, at schied there was alot of breakage in the 2.8 class but thats the the track for ya. Sure a 900hp motor is hard on oem driveline but i was at all the big events and besides scheid didnt see where the 2.8 class was any worse than any other. I broke 2 ring and pinions this year out of over 50+ hooks between the two trucks. I thought its was all part of the sport and expected it. It also seems like the only guys that want the 2.8 to be open driveline are the 2.6 guys? What do other 2.8 guys think about the issue? Is there even an issue?

So does everyone think that its to far out there to look at letting Open Driveline into the 2.8 class were people are having a hard time keeping OEM stuff alive?

What's the point of making a current 2.8 stock drivetrain class into an open drivetrain class? Especially when all of the 2.8 guys that are breaking drivetrain are running 3.0 or larger turbos bushed down already. They should just step up to the 3.0 open driveline instead of trying to get open drivetrain in the 2.8 class. Where would it stop.... before you know it people will want a tube chassis open driveline 2.8 class.

I agree. But if they allow it. Ill use it to get some extra hooks in every year. I have no problem sticking a bushing in my 83mm charger to run 2.8.
 
our 2.8 class this year was 7500lb and single rear wheels. for next year we went to 8000lb and dual rear wheels so we also added unlimited rear axle in the rules to help with the breakage factor.

it is hard to find a big rear end with the right r&p to get the final i'm after but it's not impossible. instead of going all out driveline like a 3.0 class maybe 2.8 classes can do something like we've done?
 
I like the idea of allowing bigger rear ends but factory tranny and transfer cases. Trucks could still be streetable but those worried about their rear end would have a solution.
 
I think maybe what is hard to see is the big picture. Sure it would help some of the guys in the class to go open driveline but how many is it going to hurt? How will it affect the other classes? you'll have a lot more 2.8 trucks going 2.6 or 3.0 trucks becoming 2.8. like someone said before where does it end? you have to cap it somewhere and let the improvements of the class be within the rules. If you let them maybe go a bigger rearend maybe its the tcases that break next? there will be a weak link somewhere. Its the OEM cases for cryin out loud, they were never designed to dowhat they are doing. There are limits to the stock drivetrain, we've (meaning all of you) found them boys. let really get to whats breakin the parts and limit that, maybe a turbo rule or maybe somthing to help restrict the power, more knowledgable people could speak more intelligently about that. but hey just my two cents
 
One thing that I think would be helpful is to be allowed to run something like a Dana S110 - the axles that come in 4500s and 5500s - which have ratios more amenable to street trucks.

Nice square housing too.

I don't have any info on whether they would hold up better than what we currently have though. One would hope it would help.
 
Streetability doesnt even matter anymore, its way past that, the 2.6 class is supposed to have some streetability but if they change the 2.8 to where it becomes so much more than it already is now the 2.6 will quickly be filled with trucks that arent streetable anymore either which pushes your entry level class out in my opinion.
 
Last I looked we were talking about Pulling Trucks here not I can go get groceries trucks.

LOL Thats what I was thinking. If you have a truck that can't keep an 80 together at all with aftermarket axles, spools, etc. I think driving around town is out of the picture.
 
yeah longevity and the fact you can run more horse to the open driveline which isnt leaving much else to do besides just sayin put the cut tires on and let the class be run whatya brung and hope you brought enough
 
Me personally I wouldn't mind seeing cut bar tires in the 3.0 class. It would separate the look of the difference between the classes more for the fans. And really since the open mod trucks are the only ones using them in the diesel truck pulling world and no more that what there is in the open mod class, I don't see what it would hurt. Really if you look at the tractor classes looking mostly the same aswell except for the engine size, turbo setups and weight differences, you can't really see all of that under the sheet metal. Alot of the Gasser 4wd classes all use cut bar tires aswell.

If anything happens, I would like to see the 2.8 class atleast go to an open axle rule since that seems to be the main weak link in these trucks. You can get a Dana S110/S130 axle from a 4500 or 5500 truck and it should bolt right up to the leaf springs. Leave it as a oem style tranny and transfer case and DOT tires. Just open the axle size up so that possibly there would be less breakage. Then for the Open drive line classes just allow them cut bar tires to help distiguish the classes alittle more.
 
Screw running them cut tires. Those are what separates the men from the boys. Those are no easy chore to turn I here. That helps make the mods even more exciting to see. They are a one of a kind. Though I do plan to run some here and there at local brush pulls next year just for fun.
 
Just a thought...if you are to the point in the 2.8" class that you are grenading D80's every weekend due to major HP that wasn't there just a few short years ago why not try to keep the drive train the way it is and change whats causing the rears to bust...lower that hitch height down a few inches. Sure, trucks will spin out more than they do now, revs will be a bit higher, load on the rear end should be quite a bit less and if everyone is in a level playing field (everyone running say 24") it should still put on a good show, once the sled operator figures out the new settings everyone should be landing up in the same spot anyway. Might even things out a bit. Just checked out a bunch of different rules for the gassers and it looks like in most organizations only the "Big Boys" run the 26" hitch anyway where in most diesel organizations the standard is 26" for all classes.

Just a thought and don't want to step on any toes seeing I am not pulling down there with you guys anyway.
