An earth shattering 1150-horsepower crate engine based on the current generation (GEN III) HEMI. This game changing crate engine has unparalleled performance levels and is designed to run on 93 octane unleaded fuel.

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.”

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 was designed for enthusiasts, weekend drag racers, and custom car builder looking to take their Restomod projects to the next level.

Berge, President of HEMI Tuner Performance, and co-crew chief on the DSR Drag Pak team. “The technology that’s made us successful both on and off the track has gone into creating the DSR 1150 Crate Engine.
