Speaking of explosions........
I think I may see a couple of potential problems that might cause big trouble.
First, even though the motor may be small enough to stall before bad things happen, I personally would not get within a hundred yards of that thing under pressure unless there is a safety valve in the circuit somewhere.
I looked at the unloader, and did not see that function, but it might be there. Trust me, I have been in the area of one air tank explosion, and helped clean up after another one, and safety valves are necessary.
I had one of the little air pump and tank setups that they sell with air shocks under the hood of my old truck, and I added a safety valve to that one before I would run it.
Second, given the volume you seem to be getting, I wonder about the capacity of the unloader, especially with the muffler on the output.
If you have a gauge in the system, watch it carefully when the unloader is doing its job.
Particularly when the engine is revved up. If the unloader cannot dump air as fast as the compressor produces it, the pressure is going to creep up.
Which, of course, is where the aforementioned safety valve comes in.
Remember that compressor would normally see about 150# or so head pressure, but was rated to handle at least 300 briefly.
I dove out of the way just before a freon line let go at about 450# one time. That was either a York or an A6, don't remember which.
BTW, of the two compressor explosions, one had had the safety valve replaced with a pipe plug because it kept blowing off and "wasting air". Of course, the reason it was blowing off was because the cutoff switch was sticking and it was doing its job.
The other one, had a safety valve, and it had even been tested by me a few weeks before.
It was a used system, and I pulled the valve to make sure it was not frozen or stopped up.
What I did not know was, it was way too small for the compressor. Stupidly I assumed that since it had been on that tank for years, whoever put it on there had used the right size.
Instead, one big enough to handle the 90hp compressor was "too expensive", so they went smaller.
As a result, the tank literally went through the roof when the cutoff switch failed.
Thinking about it, were you looking at a gauge when the oil collector blew? If the unloader valve could not dump fast enough, you may have had more pressure on the system than 115# and it acted as a safety...........

I guess we'll see.
