4,280-RWHP At Weekend On The Edge

Myer Stump has the pedal to the metal lately. Building on what he and his team learned at Diesels In The Mountains, Myer brought an even more aggressive dyno package to Weekend On The Edge. There, at the Golden Spike Event Center in Ogden, Utah, his common-rail second-gen took top honors on the rollers, clearing an insane 4,280-rwhp corrected and 3,503-rwhp uncorrected. Josh McCormack, who helped prepare Myer for battle with the SuperFlow, had this to say about his friend: “2026 was your year.” With a UCC crown, 48RE record, and now this (the uncorrected chassis dyno record), it's hard to disagree.

8.3L Duramax Confirmed - It's coming...

Well, GM finally confirmed it. The rumored 8.3-liter Duramax is real, it’s called the Mongoose, and GM made it pretty clear who they’re coming after. They could’ve just announced a new diesel. Instead, they made a video about a mongoose killing a scorpion (you know, Ford's code name for the 6.7L Powerstroke?). Not exactly subtle. The new 8.3L turbo-diesel V8 is headed for the 2027 Silverado HD and Sierra HD. GM hasn’t told us horsepower or torque yet, but calling it “bigger, stronger, more powerful” while directly taking shots at Ford sure sets the bar pretty high. Now we wait for the numbers.

Causin’ Trouble And Makin’ Trouble

Truck pull season is winding down, and Damon Winland is ending it on a high note. At the OSTPA’s Belmont County Fair pull, Winland drove John Humpe III and Brenda Humpe’s fire-breathing GM’s to victory. First, he piloted the “Causin’ Trouble” Chevrolet to a 351.301-foot win, then climbed behind the wheel of the “Makin’ Trouble” GMC and earned a Second Place, 343.493-foot distance. Not only is it rare for the Duramax platform to finish first and second in the world of Limited Pro Stock Diesel Truck pulling, but it may be the first time the same driver has ever taken a 1-2 finish in the history of the truck pulling sport.

"Leno's Law" Is In The Books

A big win in California for some classic-car owners. Governor Newsom signed SB 1392, better known as "Leno’s Law." Starting in 2028, qualifying 1976-1980 collector vehicles will begin receiving smog-check exemptions, with later model years phased in through 1985. Owners will still have to meet collector-insurance or limited-mileage requirements. So no, this isn’t suddenly a free-for-all for old daily drivers. It’s aimed at cars and trucks that mostly spend their lives being preserved, shown and occasionally enjoyed.

For Sale: Deadpull Super Stock Truck

Want to own one of the most dominant vehicles in the Super Stock diesel truck class? That’s right, Terry Biggs’ “Deadpull” is up for grabs, should the right buyer come along. But beyond the O’Bryant Cummins-powered Ford being for sale, so too is the toter home that hauls it and the Jeep support vehicle that maneuvers it around in the pits. Specific pricing depends on what the buyer wants. Is Terry getting out of the pulling game? Or is he building something else? One rumor hints at a possible Pro Stock tractor build… That sounds like just as much fun!

EPA Repeals GHG Regulations For Power Plants

Last week, the Environmental Protection Agency finalized a rule to repeal most provisions present in the 2024 Carbon Pollution Standards for greenhouse gas (GHG) emissions from electric generating units that rely on fossil fuels to operate. On top of that, the EPA issued a supplemental proposal which would rescind the GHG findings for fossil-fuel power plants and repeal all GHG emissions regulations for power plants. The current administration in control of the EPA has stated that the 2024 Carbon Pollution Standards require control technologies that haven’t been satisfactorily demonstrated, and which have effectively forced the closure of various power plants rather than setting a standard they could actually meet.
