Not a huge deal if the solenoid fails in either position.

You could even do it very simply in series w/ the oil system just- a storage element and a solenoid valve, fed by IGN HOT and also HOT when the starter is cranked. In addition, it better be happy w/ 8V, 10V or whatever your battery draws down to when it cranks. You would lose oil supply if your engine runs on when the key is pulled, unless you switch at the dashboard, then you have ID10T problems instead. The risk is severe if the solenoid fails closed- you'll pump the sump dry and hear a screech if enough oil doesn't follow the timing chain down from the head.

In either case, with a single shot operation, you'll get pre or post run (turbo) protection, but not both. Seems to me that dumping the turbo through dump valve that opens when it loses IGN HOT is a better way to protect it. A dead headed turbo spins on because it's no longer doing any flow work, it just has losses at the bearing and viscous losses on the internal flow. Sucking air thru the filter and blowing it out should quench that momentum fairly quickly.

Fun stuff! Makes me wish I was working, again. DAMN! Where's my drafting pencil! I need the back of an envelope!
