Vorshlag BMW E46 M3 CSL - V8 Downforce Monster Track Car ("Chainsaw Massacre")

[preston]

I ran EPAS for only a few thousand miles and wore out two woodward steering joints fairly quickly. The usual Borgeson joints are a little bigger and might last longer, but for anyone putting in epas up at the column, keep this in mind and I recommend trending towards larger joints/shafts and as always minimizing your angles. I'm not worried about Vorschlag doing the right thing so much as us hobbyists who incorporate these things.

For the record I used a Saturn Vue motor (pullout) and it actually worked very well, although I never got it on track with big stickies up front.

Another place where home brew gets into trouble is when people separate the box from the column for packaging reasons - it can be done but the sensor wires between the controller and motor are very "sensitive", and if they fail, so does power steering or even worse it can command left or right ! I heard about one crash that happened because of this.

I'm doing a Ron Sutton style front end now, so I've moved back to hydraulic (Sweet rack as he uses) but otherwise I would have happily stuck with the epas.
