Mopar caused a “stampede” when it introduced the Hellephant 426 Supercharged Crate HEMI® engine at the Specialty Equipment Market Association (SEMA) in 2018. The limited production run crate engine produces a mind-blowing 1,000 horsepower and 950 lb.-ft. of torque, right out of the box.
But what if that simply isn’t enough for you? Then Don Schumacher Racing (DSR) Performance has an option for you.
Meet the DSR 1150 Crate engine. An earth rattling engine based on the current GEN III HEMI V8. But what makes the DSR 1150 so special, is that it produces a massive 1,150 horsepower and 974 lb.-ft. of torque on 93-octane unleaded fuel.
“The performance aftermarket is a natural expansion for our brand and motorsports technology,” said 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.”
Using the technology and data developed from DSR’s Challenger Drag Pak program in the National Hot Rod Association (NHRA) Constant Aviation Factory Stock Showdown Series and NMCA Holley EFI Factory Super Cars Class.
A brainchild of DSR Performance and A.J. Berge, Co-Crew Chief of the DSR Drag Paks and Owner of HEMI Tuner Performance, the team set out to create a GEN III HEMI-based crate engine that’s durable for multiple applications. “The DSR 1150 Crate Engine is a game changer and will shake up the Mopar community,” said 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 level, extreme durability, and great drivability.”
The DSR 1150 features a displacement of 7.0-liter (426 cubic inches), it is the highest horsepower pump gas original equipment (OE) production-based crate engine sold today.
Based on the supercharged 6.2-liter (370 cubic inch) HELLCAT® HEMI V8, the DSR engine features a bigger bore and stroke coming in at 4.100 inches x 4.050 inches, using a Callies Compstar forged 4340 steel crank instead of the HELLCAT’s 4.09-inch x 3.58-inch. The block of the engine steps away from the HELLCAT block and instead uses a block from a 6.4-liter (392 cubic inches) HEMI (BGE or Big Gas Engine) V8 found in the Ram Heavy Duty pickups.
Callies Ultra H-beam rods help the DSR 1150 produce those amazing power numbers with the help of a 3.0-liter Whipple supercharger. The DSR 1150 does use HELLCAT heads along with other stock components like the 7.5-quart front sump oil pan. A custom grind hydraulic-roller camshaft setup and a slightly higher compression ratio of 9.8:1 allow for the 93-octane gas capability.
It is worth mentioning that the official numbers released by DSR Performance were achieved on the dyno using 93-octane pump gas. So it’s not just a marketing gimmick like some may think.
DSR Performance is limiting the initial production run of the DSR 1150 to just 20 units. There is an expectation to release more units in the future. The company also plans to release more exclusive GEN III HEMI parts for racers and street enthusiasts this fall.
The DSR 1150 retails for $37,950 USD and is sold directly through DSRPerformance.com and exclusive dealers.
The DSR 1150 is built to the following specs:
