2.6 Rule fix

It seems that a lot of people are pushing for the open rear differentials in the 2.6 class to prevent breakage, which I can understand if they changing them every couple of passes. So from what I have seen this summer pulling at COTPC, Full Pull and brush pulling there are a few simple changes that could save or fix the 2.6 class. Change the chargers to 3.0" smooth bore with unlimited turbine. A puller can not cheat the MAP rule this way and would hold the power at its current level. Super farm is dead in OSTPA and there is always a lot of these type of turbos for sale that are obtainable for the average puller. Do away with dual rear tires and go to single 35"x12.50". Outlaw did this to save on breakage and it seems to work. Keep all of the rest of the rules the same and let them have open rears if they what them, shouldn't need them with singles but so be it. This change would not cost the puller anything but a set of rear rims if they so choose. I think this would keep the class alive and help it grow, not disappear. Thanks for your time.
 
I like single tires but we still broke a ring and pinion running only single 35x12.50s. Bringing that up is a good way to get 2.6 pullers stirred up though!
 
Nothing would be full proof plan but this would slow down the ring and pinion failures. If you so choose to go open rear this would eliminate it, and not send the problem to another part of the drive line. With the turbo change all the puller would need is a new wheel and cover, and still use the charger that they have. This takes all of the money out of buying new chargers every year to keep up with latest and greatest fad that is out there to cheat the MAP rules.
 
I don't think you'll get them to do away with duals, but it's not a bad idea to minimize breakage.
 
It just seems if we do not do something to be pro active about saving the class it would just die a slow death. If organization such as OSTPA could get this to be excepted I think it would catch on as a universal rule, and also as a bonus it may slow down the complaining about the cheating and the breakage in the 2.6 class.
 
I am not disagreeing with your class idea ( 3.0 smooth, open rear, 35 x 12.50 singles ) but 2.6 guys don't seem to like losing 2 tires. The outlaw rule I believe does reduce breakage but has been far from popular. This class would reduce the cost and I think some 2.5 guys would move up. We will have to see what comes out for 2015.
 
I think you are right there are some 2.5 guys that would be able to move up and compete in 2.6 without a lot of money. I also agree removing the dual tire may not end up being a popular decision by some people but, it would reduce the breakage instead of just moving the breakage onto the transfercase or the transmission. I think a lot of people would be surprised on how well a single 35 tire will work instead of the duals.
 
I think the biggest issue with going to a single tire would be most of the trucks currently pulling have dual set ups already in place, this would require many people to buy different rims and some cases tires to keep pulling.

If smooth bore is the answer which I do agree it would solve the gray areas in the rules , why not make it 2.6" or 2.8" to pull the power back some?
 
I think if you would take the smoothbore down to 2.8 it would take the horse power levels below 1000 hp. At that point you would be making less power than good 2.5 trucks. As far as the duals go I am currently also running a 33x12.5 dual set up, but for $300 or $400 I can buy two rims and that would be well worth not spending $200 on ring in pinon all summer.

Because 3.0 smooth bore turbos are already available. We don't need to make a new turbo for the class. 3.0 turbos can be had off superfarm tractors across the country.
I also don't know that going back in power is exactly the idea but maybe limiting the power and $$ to get some of the 2.5 trucks to jump up.
 
Superfarm chargers are 3x3 the exhaust side would not work. So everyone is still going to buy a new charger.
 
Not that many superfarm classes run a 3inch exhaust any more. 466ci tractors run 3x4 turbos. So you can find smoothbore turbos with 3-4inch exhaust. They are for sale every winter on pulloff if you want to save some money and by used. Alot of guys switch around between small and large turbines to see what rpm range works better for them.
 
A 3x3 makes the same power as a 3x4. Turbine selection is based on rpm and ci. A 3x3 would work on a truck if setup correctly.
 
My opinion is if you could get a few of the organization to put a 3x3 charger class with all the same 2.6 rules. With the exception allow open rear ends. I'm sure they could get few pullers to commit to this class over the winter, and I'm sure after it took off you would pick up a few 2.6 guys with the ring and pinions blues. I could be wrong but it's my opinion. I would in on the class in it ever happens.
 
A puller would not have to buy a new turbo unless they are running a Gt55 frame size of charger, and the bulk of the people that a in the 2.6 class are not. Buy a new cover and make it a smooth bore, get a 75mm wheel spin it on and run it. If the puller does not want to modify the current turbo that they have, as stated before, they could go on pulloff and buy a good used charger that is already 3x4 or 3x3.

You can run a smoothbore cover and 3inch compressor on a gt55. Its all about setup.
 
I think that you are correct pick017, if a group started with these rule puller turn out would go up. I also think by going single rear that it would also draw in or retain the pullers that do not want to go open rear. If a puller would choose to go open rear that is their decision, but would not be forced into it to keep up with the current power levels. All but a few of the 2.6 trucks are running a stock rear end housing, so the singles would keep the money out of staying competitive in the class.
 
OPEN REAR then will equal t case failure... i am all for getting rid of 2.6 all together and adding a 4.1 single cut tire class instead..
 
I agree that open rear will just send that problem to another part of the truck. By going to this type of rules you could put the 2.5 and the 2.6 class together as a 3" smooth bore class. With both classes together pay outs would be better because the class sizes would be larger.
