Thread: EFI Options

Tweet

Back to basics, I have a 650 holley, performer intake, on a 327, got it running so sweet. Is a EFI system really going to give me anything for $2,000+? Or is it just the next thing people have to have? Seems like a lot of bucks and may not be worth it. (I drive the equivlent of coast to coast twice each year.) Opinions?

Scooting,
What I like about EFI is the ability to make minute tuning adjustments in a matter of minutes. With a wide band O2 indicator and a vacuum gauge you can pinpoint any spot in your fuel delivery that is too rich or too lean, and make adjustments over a nominal 500rpm band and a couple of inches of MAP on a laptop. If your driving takes you to elevation extremes, like coastal plains to the high mountain passes of Colorado then I think you might enjoy EFI, provided you like to get into the graphs & curves and learn how they work together. On the other hand, if your driving is all in a region that doesn't have wide variations of elevation, and if you have your Holley dialed in so you're getting the mileage you want without any performance balks then spending the bucks on EFI may not make sense. I knew from the start I wanted EFI, so I never made the investment in the intake & carb route and I enjoy tinkering with my EFI to maximize my efficiency in cruise, but give me a dialed in mixture at full throttle.
