When I take my supercharged 88 LX to the track my gas choices are 101 unleaded or the 114 octane leaded. The car has all emission equipment including cats. If I run leaded gas so that I can crank up the boost and timing, how long before I ruin the cats and O2 sensors? I would not mind replacing the O2 sensors once a year or so and the cats every two or three years. Does anyone have any ideas? Also, if I ruin the cats with leaded gas will the car run poorly or will emissions simply go up?
