1,200 HP on 93 Octane: DSR Direct Connection 1200 426 HEMI®

DSR Performance, the performance aftermarket arm of the multi-championship-winning Don Schumacher Racing (DSR), has a massive powerhouse available for those looking for the ultimate performance on pump gas: the Direct Connection 1200 426 HEMI® Crate Engine. This engine is designed for enthusiasts seeking serious horsepower for both resto-mod and modern vehicles. With its impressive 1,200 horsepower output on 93 octane pump gas, the Direct Connection 1200 series combines racing heritage and street-friendly performance.

Engine Overview: Built for Power and Reliability – 

The heart of the Direct Connection 1200 is a meticulously engineered 7.0-liter (426 cubic-inch) Gen3 HEMI®, precision machined and blueprinted by DSR Performance in Brownsburg, Indiana. This engine’s design leverages a 10:1 compression ratio and a new Gen6 3.0-liter Whipple supercharger, delivering substantial power while maintaining drivability on regular pump gas. Each engine is dyno-validated with a Superflow SF-Powermark to ensure that it can handle the demands of the road, offering reliable performance right out of the box.

Key components of the Direct Connection 1200 include a forged crankshaft, H-beam rods, and custom forged CP Carrillo pistons, all working together to handle the extreme pressures generated by the engine’s supercharged setup. The HELLCAT aluminum heads and valvetrain have been integrated to provide robust airflow and durability, paired with Manton Performance push rods and ARP fasteners for added reliability.

Versatility in Fitment and Fuel Options – 

The Direct Connection 1200 crate engine is compatible with a wide range of vehicles, making it an ideal choice for resto-mod projects and modern muscle alike. It can be installed in classic Mopar A, B, and E-Body vehicles and contemporary models like the HELLCAT, Demon, Trackhawk, and TRX. For off-road enthusiasts, the engine is also a fit for Jeep® Gladiator and Wrangler models, making it a versatile solution for those seeking power and adaptability.

The engine’s compatibility with 93 octane pump gas means owners won’t need to search for specialty fuel, making it more accessible for everyday use. Additionally, the engine can be tuned to run on E85 for those looking to extract even more power.

The Schumacher Crate Engine Series: Three Configurations for Custom Builds – 

The Direct Connection 1200 426 HEMI® Crate Engine is part of DSR Performance’s new Direct Connection 1200 Series. This series includes three different configurations, each engineered for specific performance goals: supercharged, naturally aspirated, or twin-turbo setups. The Direct Connection 1200 Crate Engine is the centerpiece, offering a power output ranging from 1,200 to 1,300 horsepower, depending on calibration.

For those looking for a different approach, the Direct Connection 1200 426 HEMI® Long Block (LB) version offers a more customizable foundation equipped with essentials like a forged crank, billet valve covers, and individually flowed injectors. The LB is ideal for builders who want to add their own induction systems and tuning choices. Both engines in the series feature the same high-quality components, ensuring that reliability and performance remain uncompromised no matter the setup.

A Direct Connection 1200 426 HEMI® Short Block (SB) is also available.

Simplifying the Swap Process with the Seamless Swap Tool – 

Understanding the challenges of engine swaps, DSR Performance has developed the “Seamless Swap” tool to make the process as smooth as possible. This online tool helps customers select the right configuration and accessories for their specific vehicle, eliminating the guesswork that often comes with engine upgrades. It aims to minimize the time and frustration associated with parts compatibility and ensures that the chosen engine is ready to be dropped into the build.

For dealers, the Seamless Swap tool means fewer surprises during installation, no need to salvage parts from old engines, and more efficient use of shop time. DSR Performance has built a network of authorized dealers, carefully chosen for their expertise and customer service, to assist with installations and calibrations. Interested shops can apply to join this network, ensuring they meet DSR’s high standards.

Pricing and Options for Enthusiasts – 

The Direct Connection 1200 Crate Engine has a starting U.S. MSRP of $37,999. For those looking to add a touch of customization, DSR Performance offers billet valve covers in black anodized or bare finish for an additional $1,000. These high-end covers enhance the engine’s durability and provide a refined look under the hood.

DSR Performance offers several other options, such as billet crankshafts and Johnson lifters, allowing enthusiasts to tailor the engine to their needs. These add-ons help further reinforce the engine’s components, ensuring it can handle whatever enthusiasts throw at it—whether it’s for street performance or weekend track days.

Whether you’re looking to transform a classic Mopar or give a modern HELLCAT variant a serious boost, the Direct Connection 1200 crate engine offers a straightforward path to achieving 1,200 horsepower with a legacy built on the racetrack.
