Right now, I use the GM vacuum pump, but have also tried the one from Metric Mind (http://www.metricmind.com/index1.htm). While the latter is touted to be quiet, at least in my case it's noise was quite comparable to the GM pump. I was comparing the two pumps here when they were not mounted in the car. I don't have lots of choices in where to mount the pump. Right now, it is behind the front left fender in front of the tire. This is a bad place, since there is only sheet metal surrounding the pump. I have attached sheets of vibration damping material which helps. I've also tried encasing the pump in different kinds of foam. Enough foam works pretty well, but it doesn't fit in the space available any more. Also, some vibration comes out the exhaust and vacuum tubes which needs to be dealt with. A unassisted system would be nice in my opinion. The list has had discussions from time to time about removing the booster. I haven't had the nerve to try anything (yet?).

It had been raining off and on all day with downpours in the afternoon. It was starting to look like the anti-EV vortex was back. I arrived at Wayland's around 4:00 pm to find the shop full of cameras and crew interviewing Wayland. Between the weather and the distractions it wasn't looking good for racing. Marco Mongillo had arrived in his electric Fiat. We waited out in the rain for the cameras to stop rolling so we could load all the racing gear in the service truck. When the cameras stopped, we debated going to the track. With the occasional sun breaks and the dark clouds moving to the north though, we headed to the track. We arrived at the track at around 6:00, the rain had completely stopped, but the sky looked like it could open up at anytime. John drove the service truck directly to our charging area to connect the giant power cable to the PIR transformer for charging while I drove the Zombie to tech inspection. After the inspector's quick look at the car, I was off to the charging area. With a full charge, I pulled up to the water box for the first burnout since the brush timing change. I wasn't sure what to expect, and I was worried about arcing or loss of some torque from the 5 more degree advancement of the motor. I eased into the go pedal, the tires immediately spun up and turned into rolling balls of white smoke. I thought to myself Wow, the car feels like it has more torque, the launch should be interesting. I pulled up to the line next to a new bright yellow Corvette. Yellow, yellow, yellow,I hope this thing goes straight when I hit this pedal green, GO! I stomped the pedal and the car launched perfectly, the front end came up just enough to get good weight distribution, but not far enough to loose any time or waste too much torque. The tires stuck to the track and catapulted the car in a perfectly straight line. I thought oh, here comes the 1/8th mile mark, time for the motor to quit pulling so hard, but it never stopped pulling. This was a whole new car, the batteries were still cold and the brushes were barely broken in. I saw the Corvette coming up in the mirror, but it was too late I had already crossed the finish line nearly a full second in front of him. I pulled up to the shack to grab my time slip, oh, 12.4 @ 101 not bad for the first run. With another cycle on the mighty Enersys/Hawker batteries, I was ready for a second run against the Corvette (this time with his traction control on). A second effortless tire boiling burnout and up to the line again. I smashed the pedal, again a very controllable almost gentle launch (very gentle compared to how the car use to launch). The Corvette was getting smaller and smaller, it was another nearly perfect run, no tire spin, no aggressive

A 1-2 piece of plastic tube jammed in the output hole works - but it takes longer to pump down. A larger diameter tube with a sponge type filter might work better. And don't overtighten the mounting bolts. It kills the vibration mounting.

I mentioned that once before... It would be difficult to suspend the pump in the vacuum chamber without transmitting vibration to the outside. Them there's the intake/output port noise. The pump would quiet down as the vacuum increased, but it would also lead to overheating. No heat conduction in a vacuum.

The Curtis controllers, Iota DC/DC converters, Rudman regulators etc. that so many people use are not conformally coated. They are built exactly like typical indoor consumer electronics, for use in dry, clean, room-temperature environments. No conformal coating, no waterproofing, the lowest grade 0-70 deg.C parts, etc. A lot of underhood electronic modules are not conformally coated, either. Parts are rated -40 to +125 deg.C. The board is then enclosed in a rather carefully engineered, watertight, air-breathing enclosure. My Bosch ME7.5 controller is like that, and most controllers from GM built after 1998 are done that way. We do our boards that way as well. Some controllers use a carefully designed harness to act as the pressure equalizer, some controllers use the Gore-Tex breather I mentioned in an earlier post on this topic. SAE J1211 (cars) and SAE J1455 indicate what performance level should be

This causes a loss from current to charge and discharge 120 times per second the capacitance that is formed by the cable isolation as the dielectricum and the 'plates' formed by the cable itself plus either shielding or adjacent cable or the earth if it is an unshielded cable (not likely, as you would dig right into the high voltage if you are backhoe'ing away On short runs, the losses are very little, but if you are running miles and miles of HV cable, then the capacitance becomes significant and therefor the loss caused by the charging current becomes large. One power-line from (IIRC) Denmark to Sweden, through the sea straight was so long that the only way to avoid a massive loss was to convert the AC to DC and transport it at extremely high voltage (low current) as a DC voltage through the cable. To further save costs, they used the sea as return, so they had a single isolated cable without shielding and half an electrolyser on each side in the sea to complete the circuit. Don't know if they switch polarity from time to time to avoid an electrochemical migration. Overhead lines have a very small capacitance, as the plates are small and the distance between them large and low in dielectric constant (air instead of isolation) so the losses from this capacitance and the resulting current are much lower.
