When you modify, tune and push production engines you always run the risk of something going pop, but D&J Percision Machine and Firepunk Diesel from Ohio took this to a whole new level.
Their Cummins diesel engine was equipped with three turbochargers in a compound set-up, which uses staged turbochargers to blow increasing amounts of boost into the engine.
Big boost pressure results in big cylinder compression, and the insane 146psi these boys were throwing down the throat of this poor engine was just far too much as you can see in this video. Yes, that is the crankshaft spinning in clear air at the end!

What engine do you think could withstand this type of boost? let us know in the comments.

Contributing Journalist
A love of classic American and European cars drove Iain Kelly to motoring journalism straight out of high school, via the ownership of a tired 1975 HJ Holden Monaro.
For nearly 20 years he has worked on magazines and websites catering to modified late model high-performance Japanese and European tuner cars, as well as traditional hot rods, muscle cars and street machines. Some of these titles include Auto Salon, LSX Tuner, MOTOR, Forged, Freestyle Rides, Roadkill, SPEED, and Street Machine. He counts his trip to the USA to help build Mighty Car Mods’ “Subarute” along with co-authoring their recent book, The Cars of Mighty Car Mods, among his career highlights.
Iain lends his expertise to CarsGuide for a variety of advice projects, along with legitimising his automotive obsession with regular OverSteer contributions.
Although his practical skills working on cars is nearly all self-taught, he still loves nothing more than spending quality time in the shed working on his project car, a 1964 Pontiac. He also admits to also having an addiction to E30 BMWs and Subaru Liberty RS Turbos, both of which he has had multiple examples of. With car choices like that, at least his mum thinks he is cool.
