Video: ProCharged BBC Cranks Out Nearly 3,000 Horsepower

The title is correct – this incredible engine spins to 8,100 rpm and cranks out nearly 3,000 horsepower and over 1,900 foot-pounds of torque from a big-block Chevrolet foundation. Built by the incomparable Steve Morris and his gang at Steve Morris Engines in Michigan for Top Sportsman customer Tony Braglio, it’s a departure from the norm from a typical Top Sportsman engine. There’s a honking ProCharger F-3R-136 with one of Morris’ ProVolute inlet bells mounted to the front of the assembly instead of a couple of guns of nitrous plumbed in.

The engine is based around one of Morris’ 540-cubic iron-block packages, including a crankshaft from Callies, Diamond pistons, and 14.5-degree Brodix cylinder heads that have been treated to the full Morris modification list. Jesel rocker arms are used, a pair of Turbosmart USA blow off valves are installed, and other supporting parts including the oil pan are from Moroso.

The sweet, sweet jewelry atop the engine is one of Morris’ billet intake manifold designs that provides a low profile and high performance when fed the boost from the ProCharger.  To support the horsepower, 16 Moran Motorsports fuel injectors — evenly split between 325 lb/hr and half 500 lb/hr sizes — stuff in methanol from a Waterman fuel pump. Engine tuning is handled by the Holley Dominator ECU.

The engine is designed to be dependable and repeatable, as Top Sportsman racers don’t always have the luxury of an hour or two between rounds of racing. The methanol fuel means no air-to-water intercooler is necessary, reducing weight and adding consistency in terms of operating conditions at the track. The development work that Morris has done with Tom Bailey’s “Sick Seconds” Drag Week machine has translated into improvements for the rest of his customers, with the valvetrain in this piece for Braglio identical to Bailey’s engine, with easy valvetrain actuation and long service intervals.

The sounds this engine makes on the dyno are just delicious. Go ahead and click the play button, and enjoy some power – 2,955.9 horses worth of power. Insane!
