Sure the manly men of the early days of drag racing cut their teeth on tuning multiple carburetors with blowers and early mechanical fuel injection systems but many times it was more fiddling than driving of their cars. Modern street rodding has brought the need for high performance but keeping it drivable. So many enthusiasts have been looking to modern options like hidden EFI systems. Some of these systems can be ultra complicated requiring you to be half hot rodder and half computer whiz. That is where the Holley Sniper EFI systems come in. Basically you get a carburetor that is self learning and gives the modern drivability of your daily driver with the look of an old school Holley four barrel. Learn below how an EFI might worth your time when building your next street rod.
Where’s the ECU?
With Holley Sniper EFI management systems the computer or ECU is hidden internally and the unit is self-learning. This means that you don’t need to ride around with a friend and a laptop tuning the car as you drive it in every possible situation. The unit will come preset with base settings that will get most engines running and as you drive the internal computer will make adjustments on both the short term and long term tune. This means it can make minor changes for different cams, bores, heads, and other modifications. With the ignition settings controlled with this function it can adjust the timing for optimal performance and fuel economy.
Cooling Fan Control
Since the Holley Sniper controls and monitors all engine settings and readings it can control some additional features like the radiator fan. Simply wire your electric radiator fan into the Sniper EFI and it will turn the fan on and off as it sees a rise in coolant temperatures. This saves additional external wiring or switches on the dash. Modifications can be made within the tune for when the fan comes on; but we’ve found the Sniper EFI usually has a good setting right out of the box.
Can Sniper EFI Handle Boost or Nitrous?
Most motorheads can’t leave well-enough go and we tend to want to upgrade our engines for the street or the strip. Common power adders for the strip is Nitrous injection and we see more and more superchargers and turbos being used on the street. The nice thing about the Sniper EFI is that it can grow with you and easily go from naturally aspirated or to boosted or “juiced” with some Nitrous. Sniper EFI has a built in advanced boost control that will allow you turn up the boost as you please while turning the timing back and adding more fuel at the same time. It couldn’t be any easier to bolt a supercharger or turbo onto your engine and haul ass! If Nitrous on the track is your preferred speed-adder the Sniper EFI has single or multi stage Nitrous control built in that again reduces the need to add another switch, controller, or extra wiring harness.
Can I Tune Holley Sniper EFI Myself?
While this electronic fuel injection is designed to be ultra-simple to get a modified or stock engine up and running it has loads of extra features that will allow it to grow with you and your power addictions! If you want to hook up a 3.5″ LCD screen to use as a basic tuner you can or plug in your laptop to even further tune your engine to meet your needs or preferences. This is especially helpful when dialing in an engine with Nitrous or forced induction. Tune the car as you drive or at the track it
So if you want a simple EFI system that will grow with you the Holly Sniper EFI system is a good bet. It can handle 99% of engines that take the bolt pattern of the throttle body. To see our full offering of EFI systems visit our site HERE.
