At school we had about a dozen 'Jimmies' for various demonstrations/rebuild projects. Well the Alberta government decided last summer that HD mechanics no longer need to know anything about 2-stroke diesels, so we've been stripping/scrapping them all. The engines themselves are pretty much useless for anything cool; they've been "rebuilt" between 200-1000 times each by second-year apprentices so they're pretty stressed out, heli-coils in just about every hole, etc. The only usable one was already torn down by the time I got to class this morning.
But the blowers are all in great shape. The engines only ran about an hour max between rebuilds and they've never actually had a 'blower lab' so these things are about as fresh as a supercharger from the '70s could possibly be. We only had 2 71 series engines, and the blowers from those went to a teacher who's currently building a big block Chevy of some sort. But we had 3 3-53s and I ended up with one of those blowers (and a set of 53-series unit injectors, which are pretty much useless but they look cool so meh)
So I've got the following options:
1. Sell it, buy beer
2. Rebuild it, paint it, sell it and buy LOTS of beer (if it sells they're worth about $500 reman)
3. Supercharge something and have fun
4. Put it in a box and sit on it 'til it's a museum piece (lame)
But there's a problem. I own 2 1.8s (B8ME and Toyota 1ZZ) and a 302, and if my math is right this thing will not work well on any of those engines. And it's just a bare blower, the 6-71 blowers you see bolted to V8s have that nose housing with a shaft and a pulley and stuff, but the blower just bolts to the front cover and runs off the timing gears in a real Detroit. Plus I don't currently have the resources to fab a custom IM myself if I ended up with a car that would jive with it.
So uh, what should I do with this thing?
Bear in mind that under normal operating conditions at max RPM this thing is pushing about 225 CFM without actually creating "boost" (2-stroke Detroits need a supercharger to scavenge the cylinders), I've not been able to find much real data about the flow/rpm on these things but my initial research suggests it would be happy as a clam on a ~3 liter V6.
