Auxiliary Electric Fan question - ZR-1 Net Registry Forums

Tony Davila · 05-01-2014

Thanks for the info guys, I have 4 core radiator, low stat and Chip reprogrammed. I was just wondering if it would help anymore than my current configuration. Might just tap into the ground side of relay to activate. Still coming up with my operational concept for execution.

You know me I am always trying new things. Remember my water/meth install?
I'll let you know what results I get. Should have it done before BG.

Almost 12 HP increase and 10lbs of Trq (temp 64* 12% humidity)
No mods to timing to take advantage of water/meth. Car ran (felt smoother) with the injection on. I notice the difference when on vs. off.

Going to re-run again this Aug at Aaron Scott s when it is hot.

Okay finally came up with a game plan and did some testing. I installed a 12" pusher fan at the front of the condenser to help bring in more air while at idle in standing traffic.

What I found is that with the pusher fan on my temp would not rise above 200*. This was at engine idle with both primary and secondary fans activated. Temp remained constant for a duration of 10mins. When I turned the auxiliary fan off the temp then crept up towards 210* and climbing. Slowly....

I know not everyone has problems with this but I have added an aluminum 4 core radiator, 165 thermostat, Fans on at 205 via ECM and still have a creep in temp while in city traffic. This so far has seemed to solve my issue and may for others.

I am piggy back off of the fans ground signal from the ECM to activate the pusher fan when the secondary fan kicks in. This is done through an additional relay. This is so I do not have to hook up a additional toggle switch.

I have also added side curtains and lip to help draw more air in at low speed. 12" Fan is the largest you can fit. Two 12" Fans side by side will fit if desired.

This seems to help as I noticed a quicker cool down and lower temp when driving.
