Move over Hellcat; there’s a new Sheriff in town. The new boss is a Gen-III HEMI-based crate engine from Don Schumacher Racing (DSR) that produces 1,150 horsepower without breaking a sweat. The DSR 1150 Crate Engine, as it is aptly named, is the brainchild of DSR’s Drag Pak team co-crew chief A.J. Berge. If that name sounds familiar, that is because he is also the owner of HEMI Tuner Performance, so he knows a thing or two about these mills.
“The DSR 1150 crate engine is a game-changer and will shake up the Mopar community,” says Berge. “The technology that’s made us successful both on and off the track has gone into creating the DSR 1150 Crate Engine. We feel we’ve developed a great package that combines record-setting horsepower, extreme durability, and great drivability.”
Another notable aspect of the new engine package is it runs on 93-octane pump gas. DSR’s press release indicates that each engine is blueprinted, hand-assembled, dyno tested, and numbered for exclusivity. You can order unique “tunes” from DSR Performance’s website for OEM and aftermarket configurations, which we assume means it can be tuned for street or strip. However, the website has an EPA disclaimer, saying the engines are only designated for racing or pre-1976 model street-legal cars.
The DSR 1150 is based on the 6.2-liter supercharged Hellcat; only it is bumped up to 7.0-liters – a legendary Mopar designation of 426 ci. Notable differences in the engine are the bore and stroke come in at 4.100 inches x 4.050 inches, using a Callies Compstar forged-4340 steel crank, as opposed to the Hellcat’s 4.09 x 3.58. The block is based on the 392 BGE truck block, not the Hellcat block, which is similar, but harder to get.
The Callie’s Ultra H-beam rods help the DSR 1150 pump out that monster horsepower with a bit of help from a 3.0-liter Whipple supercharger. Hellcat heads are used along with other stock components, such as the 7.5-quart front sump oil pan. The camshaft is a custom grind hydraulic-roller setup. And the compression ratio has been bumped up slightly to 9.8:1 – just enough to still allow 93-octane pump gas. It is also noteworthy that the dyno numbers were achieved using 93 pump gas, so it is not just a gimmick for marketing.
DSR is limiting the first production run to 20 engines, with expectations to release more units in the future. But from the looks of it, the DSR 1150 won’t have a problem selling out the first batch. Furthermore, the company plans to release more exclusive Gen-III HEMI parts for racers and street enthusiasts.
“The performance aftermarket is a natural expansion for our brand and motorsports technology,” says Chad Osier, president of DSR Performance. “The DSR 1150 is a pure all-American crate engine that gives racers, enthusiasts, and car builders a new level of performance. We’ve meticulously engineered the DSR 1150 to deliver industry-leading horsepower and durability, all in a plug-and-play platform. This is just the beginning for DSR Performance, and customers can look forward to more exciting products this fall.”
If the DSR 1150 is just a start, we can’t wait to see more.
