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 \u0026amp; LT1 pump and nearly 10% more than the LT4 pump.\u003c\/p\u003e \n\n\u003cp\u003eWith 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.\u003c\/p\u003e\n\n\u003cp\u003eTested to provide over 1400 horsepower (0.52 BSFC) of fuel flow for a turbocharged LT4 engine on VP Motorsports 109 fuel\u003c\/p\u003e \n\n\u003cp\u003eFeatures:\u003cbr\u003e\n•\tPrecision machined and assembled fuel pump assembly using brand new production LT1 fuel pump cores \u003cbr\u003e\n•\t12.0 mm bore\u003cbr\u003e\n•\tDLC coated bore and piston\u003cbr\u003e\n•\tCompatible with production LT1 and LT4 fuel pump lobes and with aftermarket higher lift fuel pump lobes\u003cbr\u003e\no\tNote - some aftermarket higher lift fuel pump camshaft lobe designs may require a lash cap to compensate for the smaller camshaft base circle.\u003cbr\u003e\no\tNote - some aftermarket higher lift fuel pump camshaft lobe designs may require a higher load spring on the pump to maintain fuel pump lifter control a revised spring on the pump\u003cbr\u003e\n•\t100% hot tested pump assemblies to confirm performance and functionality\u003cbr\u003e\n•\tIndividually serial numbered\u003cbr\u003e\n•\tMaximum recommended operating pressure of 15 MPa or 2175 PSI\u003cbr\u003e\n•\tRequires consistent low side fuel pressure of 68 PSI or greater\u003c\/p\u003e\n\n\u003cp\u003eBenefits:\u003cbr\u003e\n•\tIncreased fuel flow allows higher power levels without having to resort to auxiliary fuel systems.\u003cbr\u003e\n•\tStock appearing.\u003cbr\u003e\n•\tE85 compatible.\u003cbr\u003e\n•\tCan be combined with higher lift fuel pump lobes for even greater flow rate increases.\u003c\/p\u003e","brand":"LINGENFELTER","offers":[{"title":"Default Title","offer_id":40395787829329,"sku":"L710166914","price":3995.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2115\/6365\/products\/L710166914.jpg?v=1695337348","url":"https:\/\/longboostperformance.com\/products\/lingenfelter-direct-injection-fuel-pump-big-bore-high-volume","provider":"LongBoost Performance Parts","version":"1.0","type":"link"}
