Description
Looking to convert your blow thru carbureted turbo engine to EFI or do you have a high horsepower naturally aspirated engine and want a bolt-on EFI conversion? 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. Compatible with draw thru or blow thru forced induction applications. User-friendly Boost Control with handheld adjustability. Programmable Target Air Fuel Ratios per Boost level. Advanced boost control is available via free Sniper EFI tuning software, including Boost vs RPM and Boost vs Time – Same popular boost control offered in Holley HP and Dominator EFI systems! 2.5 Bar MAP sensor included which safely works on applications up to 21.5 PSI. Built-In single stage progressive nitrous control. Features dry or wet nitrous support, progressive or non progressive control strategies, lean/rich AFR cutoff, time or RPM Based Timing Retard and much more.
