it means the timing has been advanced by a couple of degrees / teeth when it was last done to, in short terms, provide a small gain in power. but really small.. i know the foreigners do it but run mad stuff like ethanol etc so would notice more gain for them i suppose________________________________________ 306 rallye reproduction decals (full sets/individual decals) | 306 b-pillar textured vinyl weatherstrips306 slam panel esso stickers | 306 yellow / orange / pension fund red side door badges gti6 inlet manifold badges | 306 rear boot badges (p2/p3) winner of Extraction of toys from prams with outstanding vigour award 2009 [source: gti6 owners club] |

Yep, it is supposed to give slightly more power and slightly lower down the rev range too. ![]() A few members have done it here although with the ridiculously small running clearances you have to be careful when doing so. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone ![]() |

I don't think there is much to be gained in reality, my valve timing on the boosted engine is at standard settings and that's where it will be staying. ![]() ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone ![]() |

no, less if anything, as it will produce more torque, meaning smaller throttle openings required at cruise.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

i played with the inlet timing, felt more torquey (a little) didnt see a difference in fuel consumptionwhen i did this the engine lost its kick at 4500, but as said, i felt it was more like an 8v earlier on weird as that may sound |
