2.6.....ALOT of guys are still running factory chargers and that is the rules we are presently running, the next class up is open.......which is pretty much diesel powered with any amount of turbos..........
IF I WANT TO BOLT A 100% FACTORY DODGE/CUMMINS HX35 ONTO MY 1991 MODEL NON-INTERCOOLED DODGE, I HAVE TO RUN THE OPEN CLASS, BECAUSE I HAVE TO BUILD A BIGGER CROSSOVER PIPE.......so how well does that work for the smaller guys......

personally here is what i would like to see as a break down for the classes, but im a rules fanatic.........:rules::rules::rules::rules:
STOCK TURBO (no water or hanging weights, bars allowed, NO ALTERED FACTORY TURBO'S)
2.6 SINGLE (no water, 1 injection pump)
3.0 SINGLE (must use all "stock" drivetrain)
3.0 LIMITED TWINS (must use all "stock" drivetrain)
UNLIMITED SINGLE (must run "stock" trans, front axle, body, and frame)
UNLIMITED TWINS (must run "stock" trans, front axle, body, and frame)
OPEN (2 rules besides safety, engine must come factory in 1 ton or smaller truck and must use factory block and head meaning Ag, Truck, or Industrial, NO BILLET!!!!)........
all classes will be diesel fueled......
both unlimited classes and the open class are the only ones allowed to have stacks through the hood......everything else behind the cab straight up or straight down......
like i said, im a rules freak and would love to have a class for every single type of truck out there pulling......
2WD's allowed with 31 inch hitch height in all classes (thank me later, Kurt and 2wdpullr)
