Hi all, Recently bought an xj sport 3.2 with two mates, intending to do abit of preventative maintenance and take it around Europe. The car came with an unfitted 'andy bracket'. With other forum users giving it relatively high praises, we decided to test it out on a dyno we are lucky enough to have access to. Roughly a 5% performance increase, not bad for a bracket... Was fun to have the difference quantified over 'feels faster'. Would love to hear from someone who can give a bit of info on how the bracket works. We are assuming that as the bracket reduced the clearance gap, the hall effect sensor outputs a higher voltage, and this 'tricks' the ecu into shifting the relative tdc advancing the ignition? any clarification or correction over this would be great. note - The excessive drag was due to stuck rear pads ,fixed post dyno. Will be retesting sometime in the near future, giving a more accurate wheel power.
