I'm pretty happy with my electic conversion too. I stuck in a GDI 3 core radiator, new H20 pump, and squeezed an imperial 12 inch fan. I also got the imperial wiring harness that will controll both the new primary fan and the aux fan simultaneously.
The rig warms up much faster, and the needle is always below 210, right at 210 at long idle with AC on max.
I also suck in a gigantic transmission cooler (WAY overkill, but it rocks), bypassing the tank coolers, which might have helped out a bit.
Total cost (parts bought over a period of time)
12 inch imperial fan (autozone) - 70 dollars
Dual thermostatic/ac override wiring harness - 20 dollars
New H20 pump (free w warranty)- usually 30 dollars
assorted wiring bits and pieces - 5 dollars
24,000 gvw tranny cooler - 40 dollars
barbed connectors for cooler - 5 dollars
GDI 3 core radiator - 100 dollars
I probably should have done my hoses but it wasn't on my mind at the time. Pretty soon ill be sticking in some hood vent too, Ill let you know how it goes. As for HP gains, I dunno. I guess a little seat of the pants feeling at wide open throttle, like at 4000+ rpms, but no real world gains.
The main 2 reasons I wanted to do it was
A)the option to turn off the fans when crossing deep water/mud to prevent sucking gunk into the radiator, also preventing the mechanical fan from "swimming" the engine forward into the the rad.
B) With less resistance from the fan, the engine works less hard. Combined with the tranny cooler, I hope this extends the life of my drivechain.
