Anyone know who has the best price on the dual 11" Spals? Streetrodstuff has them for $249 which is the best I've found so far.

Also, as for temperature senders and relays, I'm looking at the Painless Wiring Kit, the Ron Francis Kit (@ streetrodstuff) and the CSI unit.

I'm looking for a controller that's ignition key switched, has an aux input for my A/C, and can handle the load of the spal's. I also want one which uses a thermal switch-- the old flex-a-lites I tried used a capillary tube control box, never again. Couldn't get the sucker to stop leaking.

I'm intrigued by the CSI unit but it seems to be a "single temp unit" -- i.e. it comes on at the set point and also turns off at the set point, while say the Ron Francis unit is on at 200, off at 185. Is this the case?

I'd appreciate any recommendations.

I've been through several of these units myself, and in this case you get what you pay for........

Three of the last five sets of Painless thermastat/controllers that I've used on different cars have failed.

CSI is relatively inexpensive at $79.99 and works well, but indeed has a single on/off temperature that you set yourself.

The Teltek unit runs $129.95; http://www.telkekusa.com/custom/ (http://www.teltekusa.com/custom/)
but you set whatever temp you want, from 160* to 270*, to start your fan, and likewise you set any temp to turn your fan back off. (Saves a lot of cycling)

A simple wire with diode, run from your A/C clutch hot-lead, spiced into the same #85 terminal on your fan relay, that the above controllers are using, will activate the fan when you turn on your A/C.

Do yourself a big favor, and:
1) use the controller/relay to switch the ground on/off, instead of the hot lead. This reduces the work load on the controller system relay.

2) use a 70 amp relay for these high loads. (While the common 30amp will handle the load for a little while, their life is extremely short when switching these high-end fans)
I made a large purchase of these, to handle all the electric fan conversions that I've done as of late, and can ship you one if you're unable to locate it locally.
