Re: SPICA NOS

I think a better way to avoid the cold start solenoid from overheating 
would be to reduce the voltage to it once it's pulled in.  It should 
only take a few volts to hold it and this would be a lot easier to do 
than water cooling it.  A simple timer could switch in some resistance 
in series with the coil after a few seconds.  You will need a high 
wattage resistor as you will be dissipating a lot of heat.  Another 
solution might be to fabricate a mechanical actuator into the oil drain 
plug that is right under the solenoid plunger.
