WDI Breaks The Power Stroke Record With 2,390-RWHP

Warren Diesel Injection’s Pro Mod pushed the 6.0L Power Stroke platform to new heights over the weekend. In town for the Hub City Dirt Drags, SC Diesel Repair’s Ivan Stoltzfus coordinated a captivating dyno performance with the truck strapped to the Northwest Dyno Series SuperFlow. The single turbo’d, billet block, HEUI-fired 7.0L Power Stroke received a big shot of nitrous from 5,200 to 6,000 rpm and the result was a wild 2,390 hp. It’s a testament to WDI’s years of pouring resources into the 6.0L platform, along with the progression of the company’s competition injector program—the units in this billet engine being of the 10mm hybrid variety.

Dirt Drags, Truck Pulls And A Dyno Competition

An Action-Packed Weekend At Hub City

All indications are that the Hub City Dirt Drags event saw its biggest turnout in event history this year. With drag racing (on dirt), truck and tractor pulls, a mobile chassis dyno, a road dedicated for burnouts, and a sprawling show ‘n shine on tap, it’s no wonder the overflow parking was full and the stands were packed. At the epicenter of the busy weekend in Richland Center, Wisconsin was the Diesel Truck Challenge. Nearly 40 trucks hit the dyno, hooked to the sled, and went heads-up in the dirt drags. When the dust settled, Karlyle Sauer of KS Performance & Repair came out on top thanks to a 1,524-rwhp effort on the rollers, a 376-foot sled pull, and a Fourth Place finished in the dirt drags. Stayed tuned for comprehensive coverage of this year’s Hub City show.

At The ‘Strip

ODSS Regulars Pay A Visit To Truck Fest

Outlaw Diesel Super Series competitors Keith Languell and Brad Helton (shown) returned to Edgewater Sports Park over the weekend for the venue’s Truck Fest event. Brad Helton and his Exergy-fueled and SPE-supported 6.7L Power Stroke would make their best 1/8-mile pass to date—a 5.56-second blast at 129 mph—despite having plenty of boost and nitrous left on tap. Packing a Wyse Auto Repair 4R100 since the Scheid Diesel Extravaganza, we have a feeling Brad’s late-model Super Duty is only going to get quicker from here on out. Friend and fellow ODSS racer, Keith Languell (who also pilots a 6.7L Ford) took Second Place in the Street Diesel category and made it all the way to the 7.70 Index final before rain cut the weekend short. Look for these two to be locked in at the final ODSS race of the year, Smoky Mountain Throwdown, on October 30-31.

Gearing Up For No Mercy

It’s the time of year when diesel drag racers trade in their slicks for drag radials and head to South Georgia Motorsports Park for the big No Mercy event. Without question, Firepunk Diesel is one of the more recognizable names making the trek south to No Mercy 17, but its 3-second Duster has been sitting a lot this summer. Reason enough to get some testing in before the big race the week of October 22-25. Last week, the team from Plain City, Ohio hit the track to work out any bugs. Long story short, there weren’t many. Despite the converter unlocking on the back-half, the Exergy-fueled, D&J Executioner-powered Pro Mod still managed to go 3.87 at 190 mph through the ‘660.

Transmission Tech With Goerend

Whether you’re new to the automatic transmission game or you need a refresher, Goerend offers the kind of Transmission 101 lessons anyone can benefit from. Last Friday, the slushbox experts posed this question on social media: “Why is my torque converter overheated?” They then proceeded to answer it. Just like an engine, which produces heat that must be removed by the radiator and water pump, your torque converter generates heat within the transmission and relies on proper fluid flow for adequate heat dissipation. One common source of overheating comes from having a cooling circuit problem (example: excessive line pressure with no line to cooler bypass). The latter scenario leads to the torque converter and cooler not receiving adequate fluid flow, which culminates in the converter overheating and damaging the lockup clutch enough that it drags the engine down when the vehicle is sitting still and idling.
