Before you attack with rocks and sticks, there is no power number proudly displayed at the end of this dyno video from Keeter Performance Engines. If you want a number, we’d estimate the modern monster truck engine is making some 1,500-2,000hp these days. This video is less about the power being made and more about how the engine is being tested in our eyes.
If you have ever been to a monster truck event you know that the trucks spend very little time at full throttle. By little time we mean virtually none. The drivers are constantly feathering, whacking, and pumping the gas pedal as the trucks are normally run in small arenas rather than huge stadiums where all of the power on tap can be used. That’s exactly what the guys at KPE do to this engine on the dyno. They basically simulate the type of action it will eventually see in the Big Kahuna monster truck. For the record, the Big Kahuna truck is kind of awesome. Rather than some weird cartoon body, it looks like a 1966 Chevy on steroids. The thing has a full-on retro look while being underpinned by a modern tubular chassis to compete with the big boys on the Monster Jam circuit.
Unlike the mechanically injected engines that powered these trucks forever modern romping, stomping monster trucks use EFI and in the case of this truck Holley EFI. The way the engine reacts and works at part and then full throttle is awesome. It is ultra responsive and you can see the fuel injectors feeing the engine just under the injector hat and above the Littlefield blower.
Again, there’s no power number shown but this is a pretty fascinating test of an engine and boy does this sucker sound awesome with the hammer being ripped back and forth!
