Editing Z31/Electricfaninstall php (section)

== Other Information on the Swap ==

I tested my fan and it drew 21 amps on low, and 35 amps on high. When the fan kicked on I noticed no difference in idle speed but my stock voltmeter did momentarily fall 1 volt and then rise back up. If I manually switched the fan onto high speed (it wasn't hot enough to get the controller to switch it to high speed on its own) the engine RPMs dropped about 100 and then came back up. It was similar to switching on the A/C at idle in a stock Z31.

With all that amperage draw, make sure your alternator is up to the challenge. My car has no amp-drawing A/C or stereo systems and my alternator is fairly new. It seems to be doing just fine with the fan installed. I will eventually probably end up upgrading to a Maxima (90amp) alternator when I start needing more current.

My Taurus fan is not silent. I assume this is from old age and sitting in a junkyard. I think that with some electric motor cleaner (I found some at a local R/C hobby shop) and some WD-40 I should be able to make it whisper quiet. It's not any louder than the stock dual fans on my 94 Mazda 626, but you can hear it when it comes on. High speed is quite a bit louder than low speed.

These things move a lot of air. I have read that on high, the Taurus fans flow more than 3300cfm. When mine came on for the first time (on high) the fan literally swept the floor under the radiator. Dust and radiator debris flew into my engine bay.
