Latest VexUs test results......
Hello all,
Just completed another bench test run for 30 minutes continuous at 2,250 rpm. Closely related to highway speed at cruising. Ambient temperature today = 92.5 degrees F. Temperatures on ALL components pretty much peaked within the first ten minutes of operation and never went a single degree higher throughout the remainder of the test.
Here's the setup: discharge caps = three oil filled MW caps wired parallel, total capacitence = 2.5uF, lowest voltage rating of the 3 is 1,750VAC
MAX recorded temp = 96.5 deg. F. at top of caps
Voltage TRIPLER using three electrolytic caps 120uF 450V and three 1N5408 diodes, 1000V rated at 3A, voltage output = 460VDC
MAX recorded temp = 98 deg. F. at top of 1st cap. Cascading temp drop to 3rd cap in circuit at 93 deg. F.
Diodes remained at same temp throughout test.
Storage cap between tripler circuit and resistor is 15uF 450V
MAX recorded temp = 98 deg. F. at top of cap
Resistor used is 100 watt bulb = 10.4 ohms
Well lit, continuous brightness fluctuations throughout test.
HV blocking diodes at each spark plug are NTE517, 15KV rated at 550mA. Used two diodes parallel at each plug. Spec sheet says operating range is up to 302 deg. F.
MAX recorded temp = 120 deg. F. at cathode end, anode end varied from 5 to 10 degrees cooler than cathode end
Spark plugs are "COPPER MARINE" by Champion 827 M L76V
MAX recorded temp = 99 deg. F.
And when I sprayed water mist on the plugs..........OH MY GOD!!! The intensity went to "WAY COOL" I will shoot another video tomorrow, until then, yall have a good evenin'.....................................Mike
