Vintage Air vs RPM
I have a Vintage Air system on my 72 with an LS3 in it. It has a Sanden Compressor on it. I have heard they do not like a lot of rpm when the compressor is engaged. Has anyone used a cut out that shots off the compressor at a certain rpm? Is it even needed? I don’t plan on spinning mine much above 6200 rpm as the hydraulic lifters don’t really like it and power is about maxed out there anyway. I have heard some use a MSD rpm limiter but does anyone else do this or am I creating more work than is needed.

I did it on a friends worked 327, I just used a relay and a RPM switch interrupted the wire to the compressor. - I can't remember but I think it was an Accel rpm switch. Works off the tech wire on the distributor or box.
He asked if I could do it so I did. I think Speedway has the switch as does Jegs

There is a mystery orange wire that VA says is not used but if you go into the diagram it is used for a full throttle shut off. I wonder if I could tap into that with a rpm shut off. I’ll have to give VA a call on this I would assume. It’s all out in the open right now I want to do it now instead of taking it back apart later.
