How much of an advantage is Open Driveline?

How much weight would it take to even out.

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?
 
In my mind it all comes down to the ability to change the gear in the truck to suite each track. Some will say that this ability is an advantage, I would think that the only way it is, is if you know what gear you need for each track. This would make track reading very important. If someone was good at reading a track and guessing at sled settings it would help but if not it could hurt just as much.

Here lies a common misunderstanding about open driveline having these wild gear changes and Jerrod im not picking on you but ive been asked/told this a hundred times since ive put my open drive line in that i have the ability to change gears to fit the track. There arnt these huge jump in gears like everybody would like to believe. I run 2 gears this year: 1 is a 2.1:1 and the other is a 2.3:1, so tell me how much difference there is in my wheel speed? Its about about 1-2 mph. if you ask anybody else with OD they will tell you the same thing or that thay dont change gears and run the same one all the time. When i ran at Scheid , TS and Indy to my knowledge i was the only truck to change a gear at any of these events, pretty easy to tell if you see a guy under a truck with a set of tools, now thats not to say they didnt do it at the trailer but we were changing them sitting in line but it was one of those two i mentioned, so to me to use that as an excuse or complaint about OD just doesnt make sense. It is cheaper to dial in a setup when it cost $250 a piece for gears but a OEM can be dialed just as well with rear end gears just not as easy.$.02
 
Juist from some of the ruels ive seen in order to meet the weight requirements only 200 would be needed
 
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?
 
Example #1
In 2008 BSTP pulled against the mod trucks in Mackville, WI. They weighed in at 7500lbs and we (stock driveline trucks) weighed in at 8000lbs. They put about 35-40' on our best truck at the time.

Example #2
This year in Elkhorn, WI at the BSTP hook, a 3" single, open driveline truck, with dot tires from IL came up and pulled against all the stock driveline trucks. Both weighing in at 8000lbs, the OD truck put 30 feet on 2nd place.

Example #3
At the BTPA hook in Grayslake, IL 2009 a open driveline truck with dot tires weighing in at 6200lbs didn't win, but was within a few feet of 1st place that weighed 8000lbs.

Example #4
BTPA hook in Union Grove, WI 2009 Stock driveline truck goes 315', open driveline truck with 3" single goes 350', both weighing 8000lbs.

As you can see with the above examples, a open driveline truck has a substantial advantage, due to the fact that the motor can be "turned up" much higher without the risk of driveline breakage, and due to less frictional loss in the transmission and transfercase.

Everyones motor can be "turned up". That doesn't really have anything to do with an open driveline giving a footage advantage or not. If you have the power run it. Its these silly excuses which is why it will never be able to be worked out. Which is fine. Everyone has their own class. But an attempt to combine the 2 in order to put on a better show at a certain small event with only having a single class won't happen cause of those type of excuses. That was the mother of all run on sentences!

I can't tell what your trying to say, but my examples show that separate classes are needed, and you can't run open driveline trucks with 1 ton driveline trucks.
If you have 1200+ hp in a 1 ton driveline truck, you won't beat a 900hp open driveline truck, hell, you probably wouldn't beat a 700hp 2.6 class truck. Bottom line is, if you can't pull the sled to the end of the track without breaking, the power is useless.

Again, not real sure if we agree or disagree with one another, but my real life example shows what happens when the two are paired together.
 
Please tell me your joking! And if not what rock have you been hiding under? Brad has the scheid 3.0 truck black with lightning bolts on it
 
Heard the name before, seen the truck too. Just couldn't match a name or face with a truck..

So humor me..... What does he or his truck have to do with any of my posts?
 
Just that its one of the baddest trucks in the country and if it came to Wi and ran against the baddest Wi has to offer which im not saying Wi doesnt have any elite trucks but ive never heard of anybody saying they run BTPA that ive ever run across at a national event.

I agree, it's a good running sob. Still, for the 3rd time, where did I compare his truck in any of my posts?
 
Example #2 and 4 both had duals on their trucks and none of the other trucks did. And they were dually tracks. Not sure how much more the duals added, just saying they had 'em.

I stand corrected on Brad coming to Wi was going off some body else post but thats not the point. What are BTPA's rules? Who are the top trucks that got beat by 30' i mean if they are street trucks and not national caliber 2.8/3.0 trucks you cant compare the 2 its apples and oranges
 
I ran within 5-10ft of ladell and jeremy (both open driveline) in the 3.0 East Coast class this year. I have OEM driveline with the D80 welded in and a drawbar style hitch, and was only running an off the shelf 3.0 s400 and a 12mm pump. I dont see the big deal runnin with open driveline trucks.
