Anyone Use the electric power steering EPAS - Saturn Vue assist in a full track car?

[darkostoj]

I'm building a 68 Mustang max effort time attack track car. It is getting a 2020 GT500 drivetrain, and I really liked the idea of an electric steering assist with a manual rack.

I like how the Saturn Vue stuff is OEM, can be mounted out of the way under the dash, and the assist is adjustable with more or less assist off a knob.

I have heard a few really like them, and others say they are not great.

Was hoping to get more opinions on a full effort track car, would like to do it once, and do it right.

Just got the drivetrain sorted out of the donor car for those curious.

I do see several road race cars that run oem electric assist units but have free air plumbed to cool the unit as they over heat and shut off. Unfortunately I cannot confirm which units.

I installed EPAS from a Prius in my 67 Cougar with a TCP manual rack:

If you're using a 2020 GT500 drivetrain, I assume you're also using the computer system that came with it. Have you looked into using the GT500's electric rack? You'd likely need to work out tie rod ends to get the length correct but the electronics might make it a plug-and-play setup for you. I don't know enough about Ford electronics to say what would be needed but if you can make it work it would be a better solution than using an EPAS.

the electric rack would have been nice, but the pivot points are too wide and we will not have optimal geometry and bump steer.
