Holley EFI
HOLLEY EFI DOMINATOR ECU
The new standard in EFI with virtually unlimited capabilities Integrated electronic transmission control, drive by wire throttle control, dual wideband oxygen sensor capability, extensive amount of inputs and outputs for various combinations, and much more
Dominator® EFI Vehicle Management Systems are intended for non-emissions street and racing engine applications. In addition to the transmission control, drive by wire, and dual wideband oxygen sensor options, Dominator® systems have nearly unlimited capabilities to control any power adder, input, or output you can throw at them. Need to run a turbocharged, nitrous injected 8 cylinder running water-methanol injection? No problem with Dominator® EFI. How about control a 4L60E transmission as well as the fuel and spark on your street rod? No problem. There are also enough inputs and outputs to allow the Dominator® VMSs to serve as their own data acquisition and control module. The Dominator® VMS will eliminate the need for additional controllers as they are all contained in this one unit. The only thing limiting the Dominator® Vehicle Management System is your imagination!
Looking for a plug and play alternative for your stock or built late model factory EFI engine? How about a replacement ECU for your older Holley C950? Holley has you covered. HP EFI ECU and harness kits are designed to be used with popular factory EFI engines as an alternative to the factory ECU and harness or as a replacement for your C950 ECU. The HP allows you to accurately control the fuel and ignition of your engine along with additional controls for nitrous, boost or water meth.

Ultra I-Beam
- Ultra connecting rods are made entirely in the U.S.A. Every Ultra connecting rod is produced from specially formulated TimkenSteel 4330V steel. This material is then precision forged in Michigan and fully machined in our Fostoria, Ohio facility. Many geometric nuances have been incorporated into the design of Ultra connecting rods. These design features enhance the Ultra against specific loads and stresses which are applied to connecting rods subjected to high load, high RPM applications. Ultra connecting rods are fastened by high alloy cap screws made specifically for severe duty service by ARP Inc. Produced with rolled threads, these unique bolts offer improved thread engagement for a smoother more consistent net clamping load. To eliminate deformation and extrusion only AMS 642 bronze alloy is used within the wrist pin housing bore.

The next step in the Compstar line up. All the quality, reliability and workmanship you have relied upon for years from the Compstar line up is taken to the Xtreme. Specifically designed for power adder and diesel applications. The Compstar Xtreme utilizes the same proven 4340 material and ARP 2000 or L19 fasteners. Strength is added by thickening up the flanges of the H beam and a reduced depth of cut towards the center of the rod. Then non-essential weight is taken out of the beam to help keep the overall weight of this rod in check.
