Using the “while we’re in there” MotoIQ mantra, we installed a “fan delete kit” which includes an 80* thermostat and a low temp coolant switch to activate the auxiliary fan circuit earlier. The auxilary fan will now be our primary fan source.
The new SPAL fan was wired to a switch in the cabin to activate only when desired. The primary reasoning for this was for after on track usage we wanted to be able to turn the fan on/keep the fan on for cooling purposes.
When running without the SPAL fan activated there were no heating problems while using the AC, even in the heat of Southern California or on our cross country trip from CA to OH. It was nice to know though that if the temperature needle ever crept past our comfort zone there was an option to turn on the SPAL fan.
The next installment of Project E36 will cover the new SPEC clutch along with the dyno numbers everyone has been waiting for from our new S52.
