Hello all, I finally got the genny box completed and installed and tested. The thing seems to work OK and after a couple of hours running full tilt the bus refused to catch fire.
I made temp measurements each quarter hour of the test of exhaust temp, muffler temp, entering/exiting air cooling temps, box temps and oil temp. I then compared them to the test results I had obtained on the original Yamaha 3K genny some time ago. You're lucky hat I can't figure out how to make chart or graph work here on SKOOLIE or this would be even more long winded
In a nutshell this is what I found:
Little to no change in exhaust gas temp
31% increase in air cooling exhaust (131/174)
42% increase in oil temp (140/200)
I'd consider the results to be at the upper end of where I'd want to see them and I'll consider a pulling fan on the air exhaust to help things along. I'm Ok with the oil temp up to 240 degrees but I sure don't want to cook the computer!
I'll post again in a fw minutes as my lap top is saying bad things about it's charge.
