Diesel Power Products at SEMA 2011

Diesel Power Products brought their custom truck to SEMA 2011 in Las Vegas. Showing off three turbos in one engine compartment, Diesel Power Products made a name for themselves once again.

Spokane, WA, November 16, 2011 --( Cooper Rasmussen, sales manager for Off-Road Power Products, finally got the chance to show off his long-term project. Aiming to reveal the results at SEMA on November 1st, 2011, the project was predicted to electrify both the off-road and the diesel community. Rasmussen didn’t let anyone down.

Many diesel enthusiasts have heard the hype revolving around the new Borg Warner EFR line of turbos. This includes talk about their gamma titanium turbine wheels, dual ceramic ball bearings, water-cooled bearing housing, large internal waste gate, compressor recirculation valve, and stainless steel turbine housing. With the promise of a turbo capable of out-spooling any that are currently on the market, the diesel industry is salivating for a chance to get these turbos into their trucks to see them perform. Rasmussen and Diesel Power Products were included on that list.

Rasmussen’s project idea was simple: Diesel Power Products could run smaller turbos that would spool just off of idle and move the volume needed to formulate the necessary gains.

After discussing the idea with Shane Williams from Industrial Injection, Rasmussen decided to do something that had not yet been tried on a Cummins: run three smaller turbos in parallel, with each turbo being serviced by 2 cylinders. Williams and Rasmussen settled on using the 6258 model of the EFRs. These are part of the B1 frame size series and feature a forge-milled extended-tip compressor wheel with a 49mm inducer diameter, 62mm outer diameter, and 58mm outer diameter on the turbine wheel. The A/R ratio is .64 with a T25 inlet flange.

The first step was to design the exhaust manifold. With the requirement of lining up the exhaust pulses, Rasmussen had to keep the piping runs to the turbos as equal in length as possible. He enlisted the help of Luke Shuman from Hazzard Fab. Worx to handle the fabrication, the result being nothing short of a work of art. Steve Heye from Heatshield Products furnished the project with several rolls of his high-temp header wrap to aid the spool-up process and decrease engine compartment temperatures. Shuman also fabricated charge air-cooler piping and a collector pipe for the exhaust. Both worked flawlessly.

At 1:00 a.m. on October 31st, Rasmussen fired up the truck. After a couple of quick test runs and a check for leaks, Diesel Power Products left for Vegas. It was 2:30 in the morning. Twenty four hours later, the guys arrived at SEMA 2011 in Las Vegas, Nevada.

The goal of the trip was to get attention for the truck and the business, but Diesel Power Products is notorious for their fundamental aspiration of pushing past industry standards and thinking outside of the box. This year, Diesel Power Products was once again successful in these ambitions. SEMA attendees were both impressed and excited by the performance of the turbos. The most frequently asked question was, “How did Rasmussen manage to shove three turbos in the engine compartment so cleanly?”

SEMA turned out to be a huge success, due to the work of Rasmussen and everyone who helped with this innovative project. Next year, SEMA can expect even more from Diesel Power Products.
