Ok, so talk to me about these engines, the DDs in particular...

[Geom]

I would worry about something else besides a runaway engine with a 50 year bus that should be the least of worries

cool, one less thing to worry about...

 One thing is certain,, no engine will run without air, so it is an option.>>>Dan

Ok the DD blower is a roots blower it has lobes most bus people all they see are the 2 lobe type which is standard those lobes are not solid they are hollow made with thin aluminum with plugs in each end  

When the engine spins so fast on a 8v71 it happens around 3800 to 4000  rpm it blows the plugs the lobes will swell and shuts the engine down I have saw this happen before on a bad buffer switch adjustment and no I didn't do the adjustment  

90% of the time when one over revs above the limit it will cost you a blower not a engine they don't throw rod,pistons and debris all over the place as some visualize they may spin a bearing and most the time that doesn't even happen  

Sometimes I wonder how GM and Detroit made the 8v71 without the help from the internet and a bus board   worry about other things geez
