  • Steve Dinan S85 is the V10 version of the S65 BMW Daytona Prototype V8 engine.

  • Engines are hand built using race tested components. Each engine is dyno broken in and tested. Results are documented as part of the build. 

  • Daley Engineering integrated dry sump allows engine to be mounted lower in the frame, decreasing the center of gravity and allowing the addition of tuned velocity trumpets to increase horsepower.

  • Engine management is provided by the latest generation MoTec M190 ECU.

  • Custom headers and exhausts are fabricated from Inconel, a lightweight, high-strength alloy that is resistant to corrosion and heat fatigue. Inconel has greater strength than stainless steel and superior resistance to heat and oxidation compared to titanium.

  • Each engine is dyno broken in and tested. Results are documented as part of the build. Engines are signed and numbered by Steve Dinan.
