well - overboost switch

[Ronnie's.930]

I unintentionally tested my overboost switch a couple of days ago. I changed the voltage regulator, taking off the Garretson intercooler like I have done countless times over the years, and like some kind of mega moron, neglected to connect the wastegate hose before taking the 930 for a test drive - it quickly overboosted in 2nd gear and I got the "face in the wind shield" experience. Nothing seems to be damaged - runs perfectly, pulls hard, no smoke, etc. (drove it hard for about two hours today) - but who knows. I guess if I am paranoid enough about broken rings I could do a leak down test (but would rather not). I used Racewear studs and rod bolts when I rebuilt the engine several years ago . . . What do you guys think?

The good news is that the thing now charges like it is supposed to - ha!

You can bet I won't forget that hose again!

I don't think that would have hurt it at all.
I think broken rings happen when someone holds it at too high boost for the timing and fuel being used and detonation is intense and continuous for 2 or 3 seconds or longer at a time.

Coming from you, that is music to my ears (eyes)!

Makes sense. What would be the point of the over boost switch if, when it kicks in, you're already screwed? No boost signal hose AND a grounded over boost switch = Rebuilding Forum.

That's why the switch is there. Count your lucky stars and drive that beast.
