I also have a Nash fan for the Ultra Van.   But have not installed it yet, still waiting for the pully.  I have two SafeGuard ignition systems.  One for the Ultra Van and the other for the 1964 Greenbriar.  Basically what it does is allow you to set the static timing of the ignition to a stock setting.  12 degrees BTDC is about normal, but todays fuels don’t allow that.  So  dentonation can occur.  With the Ultra Van, it’s sometimes difficult to hear the  dentonation taking place.  But with the SafeGuard you have a series of lights that let you know how may individual cylinder are being retarded at the same time.  On the Greenbriar it allows a higher ignition timing setting.  So when I’m on the flat road and the lights come on just momentary, I’m at the optimum  ignition setting.  With the Greenbriar that gives me about 12 inches vacuum in cruise and about 20 MPG.

So basically it allow you to operate your Corvair engine at an optimum setting.  If you have a Turbo, it can save your engine.

The retard function was very useful especially in California with dense air and relatively low octane premium gasoline.  This was on a well used 95 HP engine with a 180 HP turbo system bolted on it.  It worked OK until I made a large throttle body fuel injection system that developed too much boost for the old engine.  The car is back together now with a reasonably stock 145 cubic inch 150 HP turbo engine that has not had any detonation issues.  I disconnected the Safeguard when I was chasing other wiring issues and have not reconnected it yet.  I have a couple new fuel injection projects in the works, so it may get used again.
