[QUOTE="FordTechOne, post: 1486976, member: 35543"] I'm willing to bet the higher octane will make a very big difference. When the PCM detects knock and retards timing, cylinder temperatures increase dramatically. During normal driving, this would be noticeable as a loss of power, but not an overheat condition. When you're running wide open throttle in high temperature conditions, I don't think any cooling system upgrade would be capable of eliminating the excessive heat generated by the retarded ignition timing. Do you have access to 98 RON and/or an octane booster additive? [/QUOTE]
