Hi, all
A friend of mine is thinking of buying a 1066 for tractor pulling over here in the uk.
Can anyone tell me what the technical specifications of the standard farm tractor are and what the specs are for a average 1066 pulling tractor.
What are the usual modifications done.
Cheers Ed

Engine specs are
414 ci 4.3"bore 4.75" stroke, Wet sleeve, oil cooles pistons, crank driven oil pump, cross flow head. Rated at 125PTO HP.

The transmission is a 4 speed sliding gear with a high and low plus a two speed hydraulic direct and under. Has a total of 16 forward speeds with the "torque amplifier "

Shipping weight of the tractor is about 13,000#

The modifications depend opn the class and the rules you pull under. If you pull in a "stock farm" class just opening the fuel pump should get you into the 250hp range. From there the sky is the limit as far as modifications. A easy hp gain is to change the crank and pistons to go to 466CI. The stock model 100 Bosch pump and injectors can be modified for significant HP gains to the 450 to 650 hp range with turgbocharger mods and changes.(approx). From there a inline fuel pump will deliver MUCH more fuel and more reliably than the rotory stock pump. With a inline pump and proper porting,cam changes, and a BIG charger 1000HP and MUCH more can be had. These tractors seem to be able to handle quite a bit of HP in the normal weight classes. There are several companys here in USA that specialize in IH pulling parts. Or you could buy mine!??

They only run that hard for a few seconds at a time and there is alot of money put into them to help hold them together.

If I thinking right the motor blow apart right about where the camshaft runs throw the block heard that is the weak spot of the 400 # motor. when running that much power.

Thanks for the cool pictures guys, I thought holding 1000hp together might be harder than you made it out to be! Here`s another question -Diesel engined pulling tractors put out **** of alot of smoke, how much of that is unburnt fuel and secondly has anyone ever used nitrous injection to get a better fuel/oxygen mix?
