A Twin-Turbo Duramax And Speeds Approaching 300 MPH

It’s Bonneville Speedweek, and Pilgrim & Stubbs Land Speed Racing is debuting a twin-turbo, Duramax-powered carbon fiber streamliner. The latest salt-worthy creation from Maxwell Industries’ renowned streamliner builder, Steve Watt, it sports a 441 ci, Automotive Specialists Racing Engines’ built, LBZ-based engine with 250-percent over injectors and dual high-pressure (up to 2400 bar/34,809 psi) 12mm CP3’s from S&S Diesel Motorsport. The streamliner, fully controlled by way of a MoTeC M142 stand-alone ECU with proprietary S&S firmware, sends a dyno-verified 1,333 hp to the ground, thanks in part to an air-shifted, seven-speed Liberty transmission, a Mark Williams driveshaft, and a BJ Holt quick-change rear end. While no one yet knows just how fast this carbon fiber missile will be, its initial shakedown pass yielded 272.434 mph at 3-mile marker. Stay tuned for more on this stunning machine.

New 1/8-Mile Record For Ford’s 6R140 TorqShift Transmission

Back on July 25, Rowdy’s Automotive & Motorsports’ Brad Helton sent his 6.7L Power Stroke through the eight-mile in 5.85 seconds (at 123 mph), a pass that earned him the record for a 6R140 TorqShift transmission. Brad’s race program (he campaings a 5.90 Index truck in the Outlaw Diesel Super Series) is heavily backed by his long-time friends at SPE Motorsport. SPE built the 6.7L Power Stroke from crank to turbo, the six-speed TorqShift, which is said to be good for 100+ passes between refreshes, and the chassis, by way of employees John Koziel and Anthony Emilio Damico. It’s builds like these that remind us how much untapped potential exists in the 6.7L Power Stroke platform.

Will Justin Zeigler Make A Return To Pro Street This Season?

Come hell or high water, we may see Justin Zeigler’s Pro Street Cummins back in action at the Scheid Diesel Extravaganza in less than three weeks. Despite the extensive fire damage suffered at Outlaw Diesel Revenge back in June, Justin believes he and his team might be ready to return to the staging lanes at Wagler Motorsports Park the weekend of August 23-24. If that happens, expect an epic shootout between Justin and current ODSS Pro Street front-runner, Paul Cato, Cato having a solid string of recent successes while dialing in his common-rail second-gen. If, for some reason, you didn’t have plans to be at the 2024 Scheid Diesel Extravaganza, you need to make them now.

Highest HP BMW Diesel In The World

Santjer Performance Development has been killing the BMW M57 game for years, but now the company can lay claim to owning the most powerful diesel ‘bimmer in the world. During a recent visit to the Dynojet at Jelibuilt Performance, Santjer’s BMW 335d laid down an incredible 1,081 hp and 1,352 lb-ft (1,033 hp and 1,321 lb-ft, uncorrected). The Santjer-built, 3.0L inline-six benefits from a host of internal hard-part upgrades, a custom set of triple-turbos (making a combined 75-psi of boost), an SDP dual CP3 kit, and S&S Diesel Motorsport injectors. The car’s fuel-only numbers checked in at 787 hp and 914 lb-ft.

8 Days And 1,800 Miles On The Road

When you’re a southeastern Pennsylvania-based truck puller and you’re competing for PPL points, you’re going to do some traveling. So went a busy end to the month of July for Jon Manns and his jaw-dropping, “Crazy Ex” Super Stock Ford. After taking a Fifth Place finish in Henry, Illinois on July 20, Jon hightailed it to Goshen, Indiana, where he grabbed a third and a Fifth Place on July 24 and 25, before heading back east to pull at East Coast Pro-Pulling’s Hartford County Farm Fair. Back on his home soil, Jon’s Haisley-built Cummins propelled him to two First Place distances. Good friends (and fellow pullers), Clint and Faith Mills, loned him their toterhome for the 1,800-mile, 8-day journey.
