(Lead photo from Jacked Up Motorsports FB page) – We have showed you the nasty side effects of hugely boosted pulling engines failing before. The carnage is virtually unrivaled in motorsports. Sure, top fuel guys blow stuff up left right and center, but their stuff is all light weight and weenie as compared to the engines in big pulling trucks and tractors. There’s more steel in a Caterpillar cylinder head than there is in an entire top fuel engine and we’re not exaggerating! The appropriately named (for these purposes, anyway) Jacked Up Motorsports pulling truck suffered one of the most incredible engine failures anyone has ever seen last weekend at the NTPA national tractor pulling championships held in Bowling Green, Ohio.
During a hook, the Jacked up truck was proceeding down course as normal when all of a sudden to the shock of everyone the entire top half of the big Caterpillar engine powering the truck was shot through the hood and actually fired forward of the still moving truck. The crank, rods, and camshaft stayed under the hood and EVERYTHING ELSE was thrown clear. The block basically shattered at the base of the cylinder bores and all of the boost inside it at the time propelled the mass of pig iron out of the truck.
The amount of damage to the truck is kind of astounding. Outside of the obvious engine stuff there’s the fact that all of the sheetmetal in the front of the rig is destroyed. the cowl is destroyed, the windshields were knocked out, and the list goes on and on. A forklift was needed to move the debris off the track and we’d be shocked if the stuff that was shot out of the truck weighs less than 1,000lbs.
Here’s a couple of different angles of the madness below!
