Ultra Street 1985 Mustang engine

Ford Muscle shared Ultra Street racer Darrel Merryman’s 1985 Ford Mustang. Merryman reached out to Dave Guy at DGR Performance in Dillsburg, Pennsylvania, to guide him with finishing this build. Then, Ronnie Reynolds at Boosted Fabrication & Performance handled the most recent round of modifications.


This 1985 Ford Mustang uses a cast-wheel Precision Turbo 76mm Ultra Street turbocharger in the passenger-side of the nose that feeds the RGR Engines 302ci four-valve modular engine. To build the foundation of the engine, a Ford Racing Boss block, SCAT forged crankshaft, Oliver connecting rods and custom JE pistons were used.

Additionally, a quartet of custom Comp Cams turbo camshafts sit on Cobra C heads, which have been CNC-ported, had new valves and fire rings installed, and been supplemented with GT500 camshaft followers and lash adjusters to maximize durability. The engine wears a stock lower Cobra intake manifold and sheet metal fabricated upper intake.
