Dan Moncrief and Shawn Bryson's Holley EFI equipped '92 Ford Mustang, made a blistering 1/8-th mile run of 4.94 @ 142.99 mph, at Brainerd Optimist Dragstrip in Ringgold, GA, April 12th -13th. The fuel injected, turbocharged, methanol-running Mustang is stuffed with a 5.3L (325ci) LS aluminum block with a stock rotating assembly, and a Holley Dominator EFI system to control it all. “Since we were started from scratch with the engine, the Holley Dominator EFI was the most logical choice for us," says Moncrief. "It offers so many features in one self-contained unit that it was really attractive from a cost perspective. It's also a very large part of our success with the engine's stock bottom-end, and keeping it alive. I'm certain that we've only scratched the surface of its capabilities.”

The Holley Dominator EFI has fuel and ignition control, a built in boost controller, a multi-stage nitrous controller, and water-methanol control. It provides a complete system with a harness and sensors that monitor and log all engine functions. "To buy all of those components individually would have cost significantly more money than the complete Holley Dominator EFI setup," says Moncrief. "Having never done much with aftermarket fuel injection, the Holley Dominator EFI has a very easy to understand interface and learning curve that won't scare away first time users. Yet it's advanced enough that even the most seasoned tuners can squeeze the last bit of power out of an engine with it. We went from having never used aftermarket fuel injection, turbos, or methanol, to running 5.60 second 1/8-mile ET.s and brought them down to 5.0 seconds in just three months. By becoming more familiar with the Holley Dominator EFI and all of its capabilities, we ran a our best of 4.94 at 142.99 mph after only 10 months of use. To say that we are all pleased with the performance of the Holley Dominator EFI system would be a huge understatement!”

The LS is also outfitted with stock 799 heads that have been ported, a CompCams .598/.601 lift camshaft, and a Forced Inductions billet 88mm ETR-HO .96A/R turbocharger. Power is put to the pavement with a Rossler Terminator IV Turbo-400 transmission, Ford 8.8 rear end, 3.55 gears, and a 25.5 chromoly roll-cage. So far, the engine and drivetrain seem to be holding up, and with the help of their crew Charlie Young, Matt Varnell, and driver Aaron Allen, Moncrief and Bryson intend to keep on trying to lower the car's ETs and keep the engine in one piece for as long as possible. “We plan to run the stock bottom end until it gives up the ghost," says Moncrief. "With 80+ passes, most with far more power than GM ever intended the engine to handle, we've been thinking that it would die long before we ever made it to 5.0s let alone a 4.94.”

The Holley Dominator EFI Vehicle Management System is intended for all engine applications and has nearly unlimited capabilities from street to full race. It also features a self-tuning fuel table and is available with an optional 5.7-inch color LCD touch-screen to make immediate on-the-fly adjustments.
