Description
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
Tested to provide over 1,100 horsepower of fuel flow for a turbocharged LT4 engine on gasoline and nearly 900 hp of fuel flow for the same engine on E85
Features:
-Precision machined and assembled fuel pump assembly using brand new production LT1 fuel pump cores
-12.0 mm diameter bore size
-DLC coated bore and piston
-Compatible with production LT1 and LT4 fuel pump lobes and with aftermarket higher lift fuel pump lobes
-100% hot tested pump assemblies to confirm performance and functionality
Benefits:
-Over 30% more fuel flow than the stock L86 and LT1 fuel pump
-Nearly 10% more fuel flow than the stock LT4 fuel pump
-Increased fuel flow allows higher power levels without having to resort to auxiliary fuel systems
-Direct fit replacement with no modifications required
-Stock OE look exterally
-E85 compatible
-Can be combined with higher lift fuel pump lobes for even great flow rate increases
Some aftermarket higher lift fuel pump camshaft lobe designs may require a lash cap to compensate for the smaller camshaft base circle
Some aftermarket higher lift fuel pump camshaft lobe designs may require a higher load spring on the pump to maintain fuel pump lifter control
Fuel pump lobe size 5.7 mm LT1, 5.99 mm LT4, 6.5 mm GT35
