Twin cooling fans............wiring?

[Admin]

I agree, fan #2 was probbaly drawing a shit load of amps to...

did it get hot idling before?  sounds like you got a workable solution.

When I had both of the fans on there, wired in series so to not overload the electrical system, it did get hotter than 180.  But I think one of my fans was shot out.

I'm anxious to hear the report as well, I think you did good...

Went out on a day trip today after work and the results were awesome.
Left fan off until engine temp was at 210 degrees and then turned it on.........
Engine temp want down slowly to 160 degrees and 20 lbs of oil pressure.
Did that same cycle three times in a row and the lowest the engine temp went to was
165 degrees and the lowest the oil temp went to was 15 lbs. During a hard run, with
the fan on, the highest the temp got to was 190 degrees. When left to idle, the temps
went down quickly. Now, since I think I've got the cooling system squared away, What
kind of automatic thermostats are the best for these temps?   I currently have to turn on the fan on manually.

They make adjustable switches and preset ones. Look at jegs and summit

That's cool.Just curious what are the radiators dimensions?

enemy set me up with one of these and he runs one as well. I really like this kit, there is one part of the instructions that is wrong. the switch wiring in the instructions is backwards or atleast the copy I got was.

I am using the one on the right hand side of the page on my 3800 v-6 and enemy has a busa.

here is one on jegs but mine came with a sensor that bolted into the water jacket just like the stock temp sensor.

Measuring the cooling surface, without the tanks, it is 12 inches tall and 18 inches wide.
With the twin fans on there, they overlapped the tanks a bit, kind of a waste.

That one is very nice!

I would try to get one that comes on at 200 or even 190 not sure how busas like heat, then shuts off 20 degrees lower... Imo your turning it on manually to high, and letting it get to cool, 50 degree temp change IMO is to much...
