Hi allAfter just discovering i can gain extra bhp/torque by retiming my inlet cam (yes, i do have adjustable pullies!) i am now trying to find out how many degrees i can SAFELY advance the timing and where can i get a timing disc from? i have done a search but could not find any detailed info cheers |

Half a cambelt tooth at the MOST, so maybe only a couple of degrees. BHP shouldn't increase but max will be slightly lower down the range, however realistically you're looking at an extra 10lbft if you do it properly  I did it by guesstimation and bricked it when I first turned it over  ________________________________________ Bye bye Sundance Kid |

half a tooth is actually about 4.25 degrees on the cam wheel which I guess is where the 5 degree figure has come from, though as you say its more like 2.125 as they run at half crank speed.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I slackened off the cam pulley, turned camshaft clockwise, then tightened up the pulley again.I have the 3-bolt pulleys though, not as simple on the 1-bolt pulleys ________________________________________ Bye bye Sundance Kid |

if you disconnect the battery whilst you do the work it'll self learn in the first short drive.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I done mine by turning the crank anti clock wise slightly and tried it a wee bit at a time till I I dared not to go any further. To be honest I think it was a waste of time (for my standard engine)..... Probably get better results from giving the car a good service________________________________________ |
