Low Temp Radiator Fan Switch

k20z3civic · 09-10-2007, 01:44 PM

I know there are a few out there for the RSX but has anyone seen one for the new SI?? I think I read someone tried one from an RSX and it didn't work.

Also.... anyone have any idea at what speed air has to travel threw the radiator to overcome the fan speed?? cuz if it's not that fast and I get the car out on an open road course this mod could make high speed cooling worse as the fans going will restrict flow then if there off. Thanks

It needs to be used in conjunction with a low temp thermostat for the full effect. The reason is because in circuit racing the engine is almost always under load so you want the fans to turn on sooner to keep the engine at a cooler operating tempature. I have one sitting on my workbench now but I'm too lazy to buy the low temp thermostat & then install both the parts.

Same as the one pictured but I'm pretty sure it for all K-series.

I already have the Mugen rad cap on my FA5. There are some interesting points in that thread.
