AO Clutch Kits Tuning Chart (Base, RC, Green)

The chart below is a guideline with very close start points with 30-33" tires riding at Sea Level elevation. (choose the Crankshaft horsepower/Wheel horsepower that best matches your X3) (Identical cars may have HP differences of up to 10 HP due to engine manufacturing tolerances so clutch kit calibration adjustments are necessary in most cases)

For High Altitudes- subtract 15% from the Published HP range of your tune to get actual effective HP. Example - 200 CHP (at sea level) x .85 = 170CHP (use the 175CHP line in the chart below as your baseline setting)

For sand dunes or large tires (35"+)- subtract 8% from the Published HP range of your tune to get actual effective HP. Example - 200 CHP x .92 = 184CHP (use the 175CHP line in the chart below as your baseline setting)

For tires 28" and smaller- Add 8% from the Published HP range of your tune to get actual effective HP. Example - 200 CHP x .1.08 = 216CHP (use the 215CHP line in the chart below as your baseline setting)

For Launch Control - Install the Lauch Control primary spring (Sold Separately) as it is a high engagement spring and will raise engagement RPMS for your Launch Control/2 Sep. Add 4 magnets to the suggested settings in the chart below compensate shift RPM for additional spring pressure.

AO.001 cam arms have 2 magnet holes - you can place magnets in either hole but magnets MUST be distributed so that the clutch is balanced. Make sure arms with identical magnets are either placed across from each other or in every other position to maintain clutch balance. Do not overfill magnet slots (FLUSH IS FULL)!

AO RC cam arms have 3 magnet holes - Add magnets to the single hole in the cam arm that sits outside the clutch to lower engagement RPM and increase low speed belt grip (this hole DOES NOT affect full throttle RPM)(magnets MUST be distributed so that the clutch is balanced). Make sure arms with identical magnets are either placed across from each other or in every other position to maintain clutch balance. Do not overfill magnet slots (FLUSH IS FULL)! Add magnets to either of the 2 holes in the cam arms that are inside the clutch to lower Full throttle RPM's you can place magnets in either hole but magnets MUST be distributed so that the clutch is balanced. Make sure arms with identical magnets are either placed across from each other or in every other position to maintain clutch balance. Do not overfill magnet slots (FLUSH IS FULL)!
