Too be honest Bill, I have no idea what Roscal has now
I suspect it is maybe one of DD early test models?
I have private from him suggesting his pump is running at 5000-6000rpm, which should be impossible!
This would explain the noise
He sent me a wave file, and it sounds like to pump is running in free air.
Yes, the pump is will produce noise in air, it is a fluid bearing pump.
Too date, only one MAG fail, due to bad cord, and several with the "ticking" which I have yet to track down. Seems to come and go, and I can not get anyone to send me one back, because it goes "away".
I have noticed, that the ticking reports stopped when we went to the injected ABS motor cap's, so I wonder if it is some over-sized caps.
And Bill, you shouldn't be pointing out problems with pumps now should you?
**"I've seen you do with anyone here who's had a problem with a CSP-whatever"
Yes Bob, I want to test a "ticking" MAG and no one will send me one
