Well what would be wrong with drilling the holes in the thermostat? Even if this delays the fan from coming on and the engine will still reach the temp where the fan operation is initiated. So maybe it goes longer before the fan needs to come on due to the engine being cooler, more a track trick that street. I know my engine runs past 192* now when it is over 90* here. I just want it to hold the temp the t-stat is designed for. Jerry could still have the fan come on sooner and at a higher rpm, remap the cooling data so to speak. the motor runs so much better on the cool side. I recently did the exhaust I have been talking about, sans headers, and the motor seems to scream and I think half of that is due to the cooler weather and half the exhaust effect. The rear cats were already hollowed out. man the resonator and muffler are heavy!
How about a second fan, a pusher type if there is room? must be a way to get the motor to run the designated temp and from what I see it is not even trying on hot days to get low enough. I preferred Leary's older form of learning. nature has so much more to offer me compared to man's inventions and allowed discoveries. Too bad timothy gave up on knowing his creator on a personal level, huh?
