Boss Cat: This Monster Caterpillar 3508 V8 Makes 1030hp and 3070 Ft/Lbs Of Torque on The Dyno!

Now THIS is a V8. The Caterpillar 3508 V8 Land Mechanical Engine is a monster in every way, shape and form. It is huge and it is heavy, weighing nearly 10,000lbs. This turbocharged beast has a bore that measure 6.7″ and a stroke that measures 7.5″. Because of this the redline is basically just over 2,000 RPM. The thing makes the kinds of torque that diesels are famous for, churning out a brutal 3070 ft/lbs at less than 2,000 RPM. Horsepower is north of 1,000 and there are loads of other impressive numbers as well. Stuff like the lubrication system with its 60 gallon capacity. The cooling system requires 69 gallons to be considered “right”.

This engine is not found in anything that goes over the road but it is found in stuff like massiveoff-highway dump trucks, tugs, dredges, cranes, drilling rigs, power shovels, and various mining equipment as well.

The engine in this video was being run after service by a shop to make sure it was still healthy and capable of doing the job it was built for. As the numbers bear out, this engine is as good as new and can be reinstalled into the vehicle it was powering. Imagine that job. Yikes!

One of the coolest numbers to share on these engines is the fact that the piston and rod assembly is two feet long from the top of the piston to the bottom of the rod. Crazy!

    The CAT 3500 engines have been a work horse the last few years in the natural gas boom the last 10-15 years all across the country. The natural gas fueled-variant engines are going up to the 3512, 3516 & 3524 confiqurations. That’s right,…imagine a V-banked engine with 24 cylinders. It’s an older-design engine with a long history of service on land and sea, but quite frankly can’t match the performance of a CAT 3600 engine.

    A 3606 engine, (6 cylinder), has a turbo the size of a Chevy 2500 truck tire and makes a shade less than 1800 HP at 1,000 RPM. Boost pressure is slightly less than “are you kidding me?!?!”
