Info

Looking to convert your blow thru carbureted turbo engine to EFI? Look no further than Holley for the Super Sniper 4150 EFI systems featuring 8, 100LB/HR Fuel Injectors capable of supporting up to 1250 HP on forced induction or dry nitrous applications. Is your combination not producing that much horsepower? No problem, Holley also offers a 650 HP four injector version for lower horsepower applications with a power adder or someone just needing additional sensor inputs. Did we mention the Super Sniper also has full nitrous control built-in? That's right, no need for a separate nitrous controller! Every Super Sniper EFI system also comes with a USB to CAN tuning cable, as well as free downloadable Sniper EFI Software to give you unlimited control of your engine.
