One thing we need to remember about chipping is the newer tractors aren't overbuilt as much as the old 806-4020 era tractors. New tractors are refined down to where they just can't stand as much overpowering as their predecessors. On top of that, they are pushing more HP per cubic inch than the old tractors BEFORE the chip is added. There used to be an old rule of thumb where a hard working engine shouldn't put out more than 1/2 HP per cubic inch of displacement. From what I understand the heat transfer from the piston to the cylinder wall heat transfer had reached it's limits. Some new tractors are a little above that ratio now at factory HP. How much more can that engine take before piston aluminum starts going through the turbocharger. How much more can it take before this annoying knock suddenly appears? If someone else wants to test that limit on their tractor it's up to him. Mine are staying stock HP. $10,000-$20,000 for a new engine is hard to swallow. Jim

In the winter, we'd play
