The 6.2-liter LT4 V8 you see on the engine dyno in this video has been fitted with two GTX35R turbochargers and a slew of other goodies from Lingenfelter Performance Engineering, including in-house camshafts, CNC-ported cylinder heads, and an intercooler intake manifold that was designed for the C7 Corvette.
By also installing a 12-mm Big Bore fuel pump, K-DI Kinetic Nozzle geometry fuel injectors, and the 7.85 mm fuel pump lobe lift LPE GT35 Gen V V8 camshaft, Lingenfelter was able to squeeze 1,435 horsepower and 1,217 lb-ft of torque from the twin-turbocharged V8 on MS109 racing ruel, without the assistance of auxiliary fueling or methanol injection. The upgraded fuel pump, injectors, and camshaft are all included in a new kit being offered by Lingenfelter for the price of $5,995 shipped.
For the money, you get a proven and tested high-flow-rate fuel system for your direct-injected small-block, even allowing you to run E85, while eliminating the need for a secondary fuel system.
