On the MD note,I am curious. Have you used any of the newer double element diodes and what reliability have you seen if so?
Hi, You are absolutely correct about the ET and MPH loss. The spragless will definately give it up in the quarter and build more heat. It is also a no-no for any type of street driving because of the heat build up. I will try to get my web guy to update if I can.

I have used some of the 10 element (paddle)diodes in some applications where I saw some abnormal wear on the 5 element(paddle) but these are in some pretty hi HP and Torque applications. Overall I have had pretty good luck with both types and have not experienced any catastrophic failure as of yet. (knock on wood). Thanks for your input.
