4,500 HP Or Bust!?
DDP’s plan to hit 4,500 hp, a new L5P Duramax horsepower record, ODSS drag racing returns to Ohio, and a pair of proven, 10-speed TorqShift options for ’20-newer Fords.
Dynomite Diesel Products’ Lenny Reed is on a mission: build a UCC-winning Cummins that’s capable of making 4,500 hp. Emboldened by Zach Hamilton, who told him to find out what his CGI solid block will hold, Mr. Reed is pulling out all the stops for UCC 2026. The block is already sitting at Perkins Diesel, where it will be machined and fitted with a deck plate. A ductile iron (and Jesel rocker) cylinder head from Wagler Competition Products is also part of the recipe, as are what should be a killer set of DDP common-rail injectors. No word yet on the nitrous arrangement, but in Lenny’s own words: “Enough to win, or see the insides of the engine…”
On The Dyno
A New, Fuel-Only Horsepower Record For The L5P Duramax
The factory sealed L5P horsepower record on fuel only has been reset—and the folks at All In Truck Performance are once again behind it. Mixing the same fueling recipe shop manager, Neal Driedger, runs—a set of Exergy Performance 200-percent over injectors and a 14mm CP3—with a GTR76/GTR107 turbo combination from Forced Inductions yielded 1,340 hp at the rear wheels. Thanks to AITP’s spot-on ECM tweaks, the 100-percent sealed (stock bottom end, heads, and head bolts, etc.) Duramax sees a safe 70-psi of boost and 105-psi worth of drive pressure at full tilt. On top of that, we’re told the late-model GMC Sierra drives amazingly well.
Transmission Tech
Fortifying The 10R140
Don’t let your 10-speed TorqShift keep you from unleashing the potential trapped in your ’20-newer 6.7L Power Stroke. Whether you’re hauling heavy or chasing a horsepower goal, WP Developments has brought 600 hp and 800 hp rated 10R140 options to market. Its fortified 10-speeds offer an upgraded torque converter (developed in-house), transmission cooler, a WPD reman transmission pump, a custom valve body that prevents shift flares and bind ups, and other select ingredients depending on which option you choose. In testing for some time, WP Developments’ 10R140 packages have been fully vetted and are backed by real-world data and a 2-year unlimited mileage warranty.

ODSS Unveils The 2026 Race Schedule
The Outlaw Diesel Super Series has released its race schedule for next season and, along with returning to a six-race circuit, is bringing diesel drag racing back to Ohio.

Additionally, Fitzgerald Motorsports Park will host the season finale race October 16-17. Both the UCC/ODR and Scheid Diesel Extravaganza events will continue to be held in their usual time slots reserved for early June and late August, as will the Rudy’s season opener (April) and Bluegrass Truck Jam (July). Stay tuned, as one more final announcement for 2026 is schedule to be revealed this Wednesday…
Competition Products
Triple Nitrous Solenoid Assemblies
If you’ve spent any amount of time in the world of high-end diesel performance in recent years, you know that Wagler is absolutely killing the game. From complete, billet-aluminum engines, unbendable connecting rods, custom water-to-air intercoolers and next-level cylinder heads to supporting parts such as its triple nitrous solenoid assemblies shown here, Wagler is fast-becoming the one-stop shop for the competitive racer or puller. N2O lovers will find that this kit revolves around the use of the familiar Lightning 375 solenoids from Nitrous Express, with the same .375” orifice size and a competition (and horsepower) friendly 22-amp draw at 13.8 volts.
