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...

    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
