My car isn't really just a dedicated racecar anymore
it's more of a street beast/drag car in search of a corner
I live in the sticks, windy mountain roads, at elevation
I've use similar set up on my old drag car, a 68 RR too
I use 2 Perma-cool electric fans
pretty shallow in design only stands off like 3-1/8" to 3-1/4"
(I have a thicker alum. 3 core rad., so it is sort of tight)
1 Perma-Cool 13" prm-19113 Summit Racing, aux. pusher (outside)
alum Blade pusher rated at 2600 cfm, at 5-6 amp full draw
(now they are rated at 3000cfm) reversible blade, to push or pull/draw
for just in case, it's rarely ever used at all (or you can reverse polarity too)
1 Perma-Cool 16" prm-19115 Summit Racing, puller for my
main cooling fan
puller alum blade, inside an alum. shroud,
fan is rated at 2950cfm @ 6-8amps, at full draw (moves some serious air)
reversible blades to push or draw/pull (or you can reverse polarity)
& also an electric water-pump 35-37gpm from Pro-form
fits right in the M/P alum (or OE style) water-pump housing
everything is wired/ran thru Bosche 30 amp relays,
& an override arming switches, Painless panel for my electronics
car stays right at around 180*-190* even driving it in Calif. summer heat
cruising, on just the 16" fan, the 13" is for
just in-case
it gets
'really hot' stuck in traffic or cruising etc.
I can cool it off quicker, never needed it or rarely
I don't use a thermostat either,
I use a restrictor where the thermostat would go
with an open appr. 5/8" hole, to help slow the water/flow down a bit
so it helps/stays in the radiator (an MRE Alum. 3 core, down flow, 22")
long enough to help cool it
hope any or some of that helps, works great for me
