As we continue our 6.4 Hemi swap in Project Orange Crush, we are constantly doing research about the swap. Learning what other people have gone through with their swaps and trying to decipher all the good info from bad so you do not have to. One of the big issues we constantly see brought up is power steering. Some of the newer Mopars have gone to electric power steering and the motors do not have a power steering pump. Others might have one but the pressures they produce may not match your setup. Well, Reilly Motorsports have put together a tool to help you out.
Bill at Reilly Motorsports had customers calling him monthly with issues related to power steering on their Gen III Hemi swaps. The difficult issue with power steering is diagnosing leaky pumps, racks and steering boxes is normally a guessing game. These parts are not cheap and not something you want to keep replacing. To help diagnose these issues, Bill put together a Power Steering Pressure Gauge Kit that is plumbed in on the pressure side of your power steering. The -6an fitting is easily plumbed in line. The fitting is followed by a stainless line with a gauge at the end for easy viewing of what your power steering system is doing.
For the last couple of years, Reilly Motorsports have had most of their AlterKtion ordered with Gen III Hemi mounts. The AlterKtion uses a Flaming River billet power steering rack and is not a cheap rack to replace. Using the wrong pump with too much pressure could blow the seals out of the rack. On the flip side, not enough pressure and the car could be difficult to turn. Many type II pumps look the same but could produce different psi amounts. Trying to find the specs of a lot of these pumps can be difficult.
With this gauge plumbed in, you can see how much pressure you exact pump is producing. You can also see if pressure drops with higher RPMs or has any spikes while turning the wheels. There are a multitude of scenarios that could present themselves but now you will have hard data to help diagnose whatever issue you are facing. When the gauge is no longer needed or in use, there is a supplied 3an cap so you can leave the port plumbed in and remove the gauge with minimal mess. Give Reilly Motorsports a call to order your pressure gauge kit and stop the guessing.
