Why did I switch to EFI?

Converting your car to Holley Sniper EFI

Why did I switch to EFI? Well, simply because I wanted the reliability of a modern vehicle in a 1968 Fastback Mustang.

Electronic Fuel Injection has come a long way in the past few years.

When some of the first Holley systems came out, not only were they confusing to install, but the computer software was also extremely slow. However, a lot of that has changed recently when Holley released their new EFI system--The “Sniper”.

For starters, has anyone ever seen a perfectly functioning carburetor? Probably not. Carburetors are a technology of the past, they simply do not have the tune-ability or functionality as some of the modern computer-based technology. Mostly to do with the fact that they’re a simple fuel delivering piece of equipment.

Carburetors work great in ideal conditions, or in places that don’t see a lot of climate change, but here on the west side of Canada, we’ve seen everything from 35+ degree weather, to 3+ feet of snow. We have some of the coldest starts, and some weather that is susceptible to vapour lock. Unfortunately, ideal conditions are never consistent at any location though.

These new Holley EFI systems, however, are designed to adapt to compensate for the dramatic changes in weather. Those aren’t the only reasons why I switched to EFI though. The fuel injection system maintains more of a constant air-fuel ratio, gives a slight boost in power and torque, and it also helps with fuel economy just a little bit.

Why don’t more people convert to EFI?

Well, my personal belief is that people are not too familiar with the whole “computer-based tuning” side of things. Even if some of the old school guys understand the concept of EFI calibration, I am sure there is a sixth sense in their head that tells them not to play with a mouse and keyboard to get an EFI system functioning perfectly. Which is totally fine! Everyone has their own opinions, and to be honest, I couldn’t blame some of the guys who prefer carburetors.

Is it expensive to convert to EFI?

Yes. It certainly isn’t cheap. But is it worth it? In my eyes--Yes. There’s something nice not having to worry about cold start carburetor lag, and there’s something nice about the added benefits which were listed above.

All in all, I am very satisfied and happy with my purchase of the Holley Sniper EFI Master Kit through Performance Improvements, and I am sure I will be shopping here again.
