In part one of this two-part segment, we dug into Holley Performance Product’s top-of-the-heap Dominator EFI system. If you recall, we noted how sophisticated this system is and how user friendly Holley has made it. With that initial look, we looked at everything from self-learning to the base maps Holley provides. This time around, we’ll investigate
It’s no secret that aftermarket electronic fuel injection (EFI) systems are becoming more and more commonplace. It should come as no surprise however, that some of the early systems were a bit complex—you had to know your way around a laptop computer to make the thing function, and even then many of the systems weren’t
In the past few years, the automotive aftermarket has really stepped-up to provide engine builders and hot rodders with modern fuel injection conversion kits that are both easy to install and easy on the wallet.

The word “iconic” may mean different things to different people,
Fuel pumps come in a variety of designs. In the most general terms, you can choose between mechanical, belt-drive, and electric (inline and in-tank) pumps. We wrote an earlier post discussing the differences between mechanical and electric fuel pumps and another on how to choose the right size fuel pump in terms of volume and pressure. One
Clutches are fickle beasts. You can get a great clutch for street driving, but it won’t support the power you’ll use when racing. You can get a race clutch, but it won’t work well for street performance. The folks at Hays recognized this dilemma and set forth to resolve it with a single clutch that
LAS VEGAS, NV — If you’ve been paying close attention to the aftermarket, you know that Holley isn’t just Holley anymore.
