@davidnunn posted:I can't answer your question directly but I can tell you about my experience with my EZ Electric PS system. Prior to installation, EZ told me to expect a slight decrease in self-centering with their system and that a small increase in caster would return the original self centering effect. After installation, I noticed no decrease in self centering, in spite of being aware and paying attention every time I turned the wheel.
If you want to find out about the SACC system specifically, I'm sure someone here will chime in. If you're considering a purchase, perhaps Gerry Romack (glpanteraclub@gmail.com) would be a good person to talk to. He's driven multiple Panteras with both systems installed (SACC and EZ Electric) and says they feel quite different. I believe he's installed both systems too. No, Gerry hasn't installed PS on his "one of two four in the USA" Pantera Si !
I am considering EPS. In doing my investigating I have come across the comment that the largest "issue", for lack of a better term is that none of them seem to self center.
SO FAR, the "street rodders, or 'hot rodders' " are my best source of information. After all, these guys have gone through countless applications. Experience counts and I will say that negative experiences shouldn't be disqualifying at this point
Consider that BOTH EZ and SACC are essentially "hot rodding" existing EPS units not specifically made for a Pantera application. I do not mean that in a derogatory way. They both more correctly are "re-engineering" an application but both are "stuck" with the qualities of the products they selected to apply.
The biggest issue that I can see is fitting the EPS unit into the available space in the Pantera. SACC has taken a slightly different approach in machining there own column. Apparently EZ has taken a similar approach but in one posted picture they are clearly showing a BMW column top and cover with an angled ignition switch.
One of the fixes or admissions that the unit is not self centering is stating a fix of dialing in more + caster. In American vehicles power steering is one way of getting the effect of greater straight line stability at speed.
I'm looking at gaining high speed stability (going straight) at high speed without using excessive + caster, but still running into a complete lack of candor on the operation of these systems.
From my investigation, across the board, the power assist gained is in the area of 4:1. The dampening effect of the road shock as a result has got to be substantial and it has got to calm down that steering wheel giggling that you get with a wide body car modification.
No decisions have been made by me at all. I'm still in the investigation stages. I'm just picking your brains at this point but I haven't lost interest in this...yet.
Yes I would love to get feedback on this subject (self centering) for EPS equipped Panteras. Wasn't there a group buy of 25 from the Michigan chapter?
