[DeTomaso] Fw: To thermostat or not to thermostat

[Will Demelo]

I don't think that fluid can flow too quickly in a rad. It's still in 
contact with all the surfaces, but there definately be an issue if it ran 
too slow. I also agree that you must run a stat on a street cat to get it to 
proper operating temps.
