Does anyone know how many amps the Urban Cooling Kit pulls while running?
In hot rods with electric fans, it's a rule of thumb that for every 100 cfm it will pull 1 amp. So a 2000 cfm will run at around 20 amps.
Where I'm going with this is that with an electric fuel pump, fuel injection, running lights and headlights on, there isn't much "extra" left in the alternator to run the cooling fan. And keep in mind that usually at the speed that the cooling fan will come on, your motor is not putting out massive amounts of amps. Fans are designed to be running max output in the 14v range. They will put out drastically lower cfm at around 12v, if you're fully burdened on the alternator.
It may not be an issue at all, just an observation.
What is the output amps of the S&S alternator?
