Engine Operating Temps

Remember a cold enging generates more HP, but how is your oil pressure? Mobil 15-50 gets pretty thick at those temps. I have a BB 429SCJ that runs a 180 thermostat and I need to block off my oil cooler duct because the oil gets too cold, even in AZ. I also run Mobil 15-50 for track events and on the street I see a 5 to 15 psi increase in oil pressure at cruzing speeds because of oil temp. You might want to change oil to a more friendly version for cold weather unless you plan on tearing up the track on the weekends.....

Keep it above 100.........

Have you ever heard of "I need to warm it up before I get on it?" Running cold temperatures may increase your HP but keeping the engine temp in the 150 degree range is just wrong. Along with oil temperature in that range. It's best lubricating properties are in a higher temp than that. You want your car up to operating temps atleast ~170 and oil to be at a similiar temp. Like I stated earlier, HOT combustion, cold intake = most HP.
