Greg, where are you finding the Spal Pwm controllers? From what I have been told Spal is no longer making them and I can't anybody who has some on the shelf.

Well -- It's been a couple years since I had to buy one... and the place I bought it from (I have two of them) also shows "no longer available".

Sad - it was a nice piece!

I sell quite a few of the Autorad units. There quality looks like something we might try and build. the PRC units look like miter cut projects with exposed welds. If I'm going to buy something that we use on one of our builds I want it to be as good as we would build or better. The Autorad Unit is really nice quality, all welds are sanded smooth and drilled and taped holes make things clean. AutoRad's radiators are bigger in most cases.

We sometimes run the fan circuit off the ECU or Ron Francis makes a really nice Controller also. It is fully adjustable and uses a wire lead that can hook anywhere to the block. It requires more knowledge to set up as far as a tem gun, But is really clean and does not use a thermostat sender. Just an Eyelet hooked to a bolt on the cylinder head.

The other hard part about the ECU fan signal is getting the AC to work with that properly. The external fan switches address that more easily.

I guess this greatly depends on the ECU. I am very new at this and can easily adjust my temperature and speed of my fans (one or both) relative to the water temp or whether the AC is running from my ECU. I also programmed it to for my AC shut off at certain RPMs and temperature.

PRC fan here. i got the setup from mike at musclerodz and i think most would be suprised at the price compared to the others. i for one like the exposed welds and i was worried they wouldnt be as nice as the ron davis stuff. luckly i was proved wrong.....

I just liked the way the SPAL PWM would run fan #1 at half speed and then ramp up as needed... and would run the fans on cool down mode after running the A/C... and that it was waterproof so you had lots of mounting choices.

But obviously that's a mute point now.

There will be TWO less SPAL PWM controllers on Ebay.... I'm bidding on both of them.

EEEEEEEHHHHHHHAAAAAAAAAA

Greg, you beat me to it

Its probably best not to start a bidding war with you!... Your pockets are deeper.
