I believe my mods are fully listed. I have been toying with some simple cooling mods. Mimi said he had 4 holes drilled in his T-stat, maybe 1/4"? This would keep some coolant flowing even when the car /thermostat was closed keeping the motor cooler. When my temp needle is at 9AM and not higher the car makes more power for sure. I have the heat exchanger separation kit. How about the holes in the T-stat? Anyone have and if so results? Any other suggestions that may seem off the wall but seem to work? Thaznks
