Waiting in line cooling....
 

So this past weekend I had a autocross event. It was about a 80-85 degree day and after a run I would blast the heat to get the temps from 220 to around 190. Then I would turn off the heat and just sit there sweating away in the car until the next run and repeating that the whole day.

currently running a MSM radiator with 90% water 10% coolant, fans work.

I had this crazy idea on my way home..Is there a way where i could stay in line with the car on after a run, while waiting in line with my AC on and still dropping my temps down to around 190 and I'm wondering if it has bin done...

Get a 52MM radiator and 4 fans... two push and two pull fans.

Ideas?

A good radiator with good fans should have you taken care of. ;)

even with the AC on?

Absolutely.

In fact. All you need are 2 fans that work together (not just when AC is on). A reroute will help even more.

You can hotwire a toggle switch to ground out the wires in the diagnostic box and force the fans on. I did that back when my relay didn't kick the fans on, boy was that a rush..

OR, do a track day. No lines, and more than 2.5 minutes of driving time in a single day.

baby steps

Why? At 220°F the fans should be on anyways on an aftermarket ecu. Mine cycle on and cycle off when waiting in line to auto-x mostly. On at 215 off at 200 with a 195°F thermostat.
