Lingenfelter Performance Engineering is developing a twin-turbo system for its 427ci LT2 engine.The twin-turbo setup is anticipated to deliver over 1,100 horsepower at the wheels (1,300 at the crank) with just 15 psi of boost.The package is designed to mirror the turbo layout of the Chevrolet ZR1's flat-plane LT7 V8 engine.While pricing is yet to be announced, the twin-snail upgrade will require an upgraded fuel system and additional components, adding to the cost.
