NRE's Twin-Turbo Outlaw 427 Crate Engine Pushes 1,200 BHP on Pump Fuel

Nelson Racing Engines has revealed its Twin-Turbo Intercooled Outlaw 427, a crate motor built for enthusiasts who want extreme output without race-only fuel. According to the company, the engine produces 1,400 bhp when fed high-octane race gas, and still delivers 1,200 bhp on ordinary pump gasoline.

That dual-fuel flexibility is the headline here. Most builds chasing four-digit horsepower require specialized fuel and constant attention, but NRE’s intercooled twin-turbo setup is positioned as a turnkey crate package that keeps serious performance within reach of pump-grade fuel.

The Outlaw 427 continues NRE’s reputation for building no-compromise V8s aimed at drag racers, restomod projects, and anyone seeking big power in a self-contained package.
