I posted that already. Without a thermostat I can’t get to 140. If it was a drag car I’d love it.
But I already know that temp or colder won’t defrost the windows. BTDT.
Plus the wife bitches about the heater not blowing hot enough air. BTDT too!
So that’s why the 160 thermostat.
Since I run more compression than most I can’t afford to gain 10 degrees of coolant temperature. It will make it much closer to detonation.
At 180 it would be worse.
So you’d be correct saying I overbuilt the cooling system. For those reasons.
Me personally I’d rather overbuild the cooling system and let the thermostat do what it’s supposed to do.
