Oil pump for transfer case/rear end.
I am looking for a pump to use with my transfer case. The transfer case (designed by me and perfected by SCS) is basically 2 spur gears on two shafts inside a beefy housing to reverse direction of my rear engine build while giving awd. So you may compare it to a rear end in many cases in the relation to the temps.
The layout is transfer case, inline temp gauge(at lower pickup location), inline thermostatic switch (180F on 165F off), filter, cooler, pump, then case sprayer. When the switch is tripped the pump and fan will kick on at the same time using independent relays.
Any recommendations on pumps and for that manner oil to use with these pumps. The transfer case also gives a .75/1 output ratio. The rpm range of the input gear is 1500 to 5000 practical with 6500 being the rev limiter. Note that the output gear will be spinning 25% faster then the input gear. The application is daily driver with highway speeds and long range trips in the works. This will be used in temps ranging from -30F to 100F.
Thanks for any info
