For the final couple of days, this inexperienced Dodge Ram has been throughout my laptop display screen in numerous places, all for a similar motive: as you may plainly see, one thing extreme occurred underneath the hood. What may probably have occurred to make a Cummins flip itself into confetti? That reply is straightforward sufficient: eight,250 RPM. Take into consideration this for a second: the traditional Chrysler LA small-block begins to get sad simply earlier than six grand and the big-blocks aren’t significantly better. Even the 5.7 Hemi wouldn’t be too completely satisfied at that velocity. The Cummins, which usually doesn’t like life above three,000 RPM or so, by no means had an opportunity. Whereas making a lap down the observe the diesel went into runaway, by no means a great factor. The truck did have an emergency consumption air shutoff system, however when it failed, the Cummins spun to over eight,200 RPM earlier than detonating in an enormous fireball.
To say that the engine is useless is an understatement. We’ve seen the carnage teardown footage and belief us, there isn’t sufficient JB Weld and crimson RTV on the earth to place that factor again collectively once more. From Energy Pushed Diesel themselves:
“The throttle caught/doable rack hung after powering via the 1/eighth mile at 120 MPH in third on a reasonable Gas-Solely tune-up that began at 370 cc’s and ramped as much as 960 cc’s. When Todd lifted after the 1/eighth mile end line, the truck saved pulling. He hit the emergency kill swap which prompts the BD Energy Air Shutoff and it didn’t actuate. (We’ve used/examined this combo of BD Shutoff butterfly / charge pipe blowoff valve a pair instances up to now with profitable shutdowns that didn’t damage the engine nor the turbos at full enhance) Sadly there was nothing he may do because the brakes are ineffective when the engine is churning alongside at full throttle so in an effort to protect the remainder of the truck and his life, Todd shifted the truck into impartial. At first look it seems that the Carillo HD Rods skilled a rod bolt failure on #three or #four gap at which level the crankshaft ejected them via the perimeters of the block beginning a sequence response. The remaining nonetheless underneath full energy #1, #2, #5, and #6 cylinders then had sufficient power to complete off the weakened block by lifting all the higher half off the decrease rotating meeting. Todd was unhurt regardless of the massive hearth and flying steel elements. Fortunately nobody was hit by the engine particles. The truck safely skidded to a cease after the engine failure punctured one of many entrance tires and Todd steered the remaining good entrance tire away from the wall. As a lot as we’d love to assert we made sufficient energy to explode a strong Hamilton block, the rod bolt failure is almost certainly the true perpetrator on this engine failure.”
