Bringing this back up. Just working on what I hope is my last oil cooler mod. Stock cooler, stock with Ford Racing,FR radiator,eliminate stock cooler and use 172 and -12 with oil thermostat that almost worked if I pulled the grill. On to a 948,-12 lines,Improved Racing thermostatic sandwich plate,Roush 7 bar grill and Trackspec motorsport hood louvers. I'm hoping to see 225 max oil temp at Watkins Glen.
