Single-Turbo 5.9L Cummins Engine – Engine Builder Magazine

We very last spoke with Steve Burton in 2021, when he explained to us all about his store New Functionality Automotive and a sweet 6.4L Cummins engine he experienced crafted. Given that then, he’s expanded into a 9,500-sq.ft. facility and employs 6 individuals. With a more substantial scale and far more fingers-on deck, there’s additional and a lot more neat builds coming out of his shop.

The Rural Retreat, VA store handles almost everything from common routine maintenance, in-property production of specialised areas, and motor dyno services to complete efficiency diesel motor builds. The store has a split-stage setup, so restore and routine maintenance gets performed on the prime floor even though engine setting up and machining get completed in the basement.

The motor Burton reached out to us to characteristic this 7 days belongs in a Professional-Avenue diesel truck, which is characterised by its 2.6-inch easy bore charger, no map ring grooves permitted.

“It’s just one of the swiftest developing courses across the state suitable now, and one particular of the most competitive in my opinion,” Burton said. “When they first switched to this easy-bore course, we all dropped about 250 horsepower and hated it. But as technological innovation came close to, we located much better ways to make horsepower. We were originally sitting all around 700 horsepower with these engines and now we’re knocking on the door of 1,200.”

Burton has constructed a couple of of these specialized engines as of late, but his most productive runner belongs to Mike Peabody out of Nova, Ohio. That distinct truck won podium locations at Scheid Diesel Extravaganza and Diesels in Dim Corners this calendar year. Burton suggests it is a person of the couple of mechanical vans that is competitive in the industry.

The 5.9L Cummins has a 12-valve block with 24-valve heads and a normal balanced Cummins crankshaft. Billet rods are necessary for the develop to deal with the considerable total of torque which is in the neighborhood of 2,200 lbs.

As it is mechanical, the staff is jogging a Northeast Diesel P7100 P-pump, paired with Infinite Overall performance Injectors. The injectors are 6-gap by 23 orifice Burton did not want to disclose the measurement of the injectors as they are portion of the “secret sauce.”

“One of the key features of this builds is the piston, camshaft and head movement combo. With the restricted air you have to get the job done with, all those 3 items are essential to best.”

For the solitary turbo, Burton ran a T6 2.6” clean bore from Apex Turbo built specifically for that course, paired with a T6 manifold from Stainless Diesel.
