Lingenfelter Big Bore Direct Injection High Volume Fuel Pump 2016-2021 Camaro SS, ZL1

Lingenfelter Big Bore Direct Injection High Volume Fuel Pump

*Fits all 2016-2021 Camaro SS & ZL1

Mechanical fuel pump flow has been one of the primary limiting factors for the aftermarket when trying to increase the power output of the GM direct injection V8 engines. The Lingenfelter Big Bore direct injection fuel pump for GM Gen V V8 applications provides an increase in fuel flow capacity over the stock LT1/L86 and LT4 fuel pumps, expanding the range of performance of these engines. At 12.0 mm in bore size, the Lingenfelter Big Bore pump flows over 30% more than the stock L86 & LT1 pump and nearly 10% more than the LT4 pump.

With the combination of our GT35 camshaft with a 7.85 MM fuel pump lobe, the Big Bore pump flows 40% more than a stock LT4 pump and stock LT4 camshaft.

Tested to provide over 1400 horsepower (0.52 BSFC) of fuel flow for a turbocharged LT4 engine on VP Motorsports 109 fuel
