Hi guys; I have recently fitted an aftermarket Davies Craig thermo fan to my car, and currently have it wired to the ignition, which is obviously not ideal. Does anyone know if the Power FC has an output that can run an electric thermo fan, or will I have to sort it out with a separate temp sensor and relay?

Cheers,

Micah

I am interested in the idea of running thermo fans instead of the stock one.My plan is to fit a front facing plenum, fmic and thermo fans. Has anyone considered this mod or know someone who has done it to a street car?

My son's S13 is set up like this and has not temp trouble even drifting on a stinky hot day. His fan unit is a double.

Some cars it works fine, others not so well. Just remember that a thermo will not supply anything like the volume of air that a viscous clutch fan can supply. From memory, at full whack, a clutch fan will pump over 3000cu/ft per min, a 16" thermo around 1500cu/ft. If your cooling system is marginal, it won't keep up. I've run them in the past and had no issues, always Davies Craig, never cheapies.

Yeah I hear you: the radiator has just been replaced with a huge PWR unit which even without a fan running, never saw over 85degrees whilst driving, and I now have a DC thermo fan on it. However, I am thinking now of adding an additional 8" fan or 2 on a separate circuit, purely for the sake of redundancy. I doubt the FC will be capable of doing what I want it to, and am now considering the Davies Craig fan switches, which will also allow the fans to run after the car is turned off...

    • Personal experience. Those f**kers burn. And are actually a PITA to put out. Next time I walk down the back, I'll snap a photo of what the inside of the bonnet looks like when that thing ignites. PS, powder fire extinguishers are useless on that stuff too as it's fibrous and when it ignites, it starts to pull apart. And you end up just blowing powder through a sieve effectively.   Like the big thing is, if it's fire resistant, it's job is to stop what burning? The METAL above it? It's just to try keep heat off the bonnet paint work.

    • That's more or less what he meant. What it really means is that you do not have to go full crazy on the build. Don't need the best oil pump, expensive rods & pistons, big cams, etc. You can upgrade whatever you want instead of using stock level items, but you don't have to. Having said that - any time an RB is opened up, if anything is getting replaced, I think the opportunity should be taken to do all the sensible upgrades. Pistons, rods, pump, etc.
    • February update 🙂 We managed to get the very last 1/18th "Extra Scale" cars stock available from bookstores in Kyoto. These are actually the last ones and will not be restocked again! Hachette Collections Japan have not decided on a release date for these or other models in the series, so for the time being these are all there are available new.  These are showing up on Yahoo auctions at inflated prices already (especially the Celica and NSX) so get yours now at a very reasonable price before they disappear!
