AZRR CYM FD Build Coming Together

the amp figure isnt exact mind you its basicly what has worked for others in the past without burning up PFC drivers. now youd have to check the drivers in the PFC to get the exact amp but i dont have that ability curently. im just wanting to know what these injectors ohm is to see where they would come out amp draw wise. so that i can chose the correct ohm injectors for my project, maybe these guys know something i dont.

I'm sure AZRR has something figured out. He might be using an FJO injector driver. He's also got gobs of injector capacity so will never probably have to run the injectors anywhere close to 100% duty.

Not that anyone would probably care (electronics are pretty boring stuff to everybody but me), but typically output current capability of a switching circuit such as an injector driver is completely dependent on proper heat-sinking and transistor/FET Ron resistance. (i.e. completely a thermal issue) If anybody has a picture of the internal heatsinks of the PFC injector drivers and their part number, I can compute close to exactly the ambient temperature at which point the silicon will self-destruct at a given duty-cycle/RPM.

I think Glen had mentioned at one time that the 4 1000 cc injectors would be run at a very low duty cycle based on the power goals I was looking to achieve.

Everyone,

A few new pics from this past Saturday. Afternarket turns now installed on the nose and thanks to Shawn Beniam for stopping over to perform my battery relocation to the rear side drivers bin. Incredible job Shawn, THANKS!!!

This is looking awesome. I hope mine looks as good as this. Great work!
