if its still running hyd lifters you'll be at the same or lower spec cams as me. | |

yes, agree with AK on this one. with that spec I would be happy with 190-200 bhp. also the cam timimg is set to the manufacturers reccomendations, try getting it on the rollers at somewhere else and asking them to adjust the cam timing to see if there is any gains there. | |

an XE with standard cams making 200lbft? and 230bhp is a bit OTT in my opinion as well, maybe 200-210 | |

the valve timing that it was set to was specified by kent cams them self and said with the spec and the valve timing set as they stated it would do roughly 230bhp, the guy showed me another corsa map he had done just b4 mine and with standard cams in it did 200lbft | |

its all in the cam timing and mapping. you can lose or gain 20bhp either way from badly set up cams and maps | |

the compression is very low | |

has the engine been rebuilt recently? it could well be that the engine needs running in, just like yours in the corsa adam. also, thats bloody good torque already from a TB setup. i would say that getting over 200lb/ft is not likely to happen with that spec. what length trumpets are you using? at what rev limit are the figures peaking at? | |

rite this is my problem, i have just got my car back from being remaped with tb's on, it has kent rally cams in not sure of the spec as ov yet, vernier pulleys, power boostvalve, ported and polished head. forged pistons and rods. its running omex 600 management with all these mods it should be running at least 220bhp and over 200lbft but its only running 175bhp and 188lbft the valve timing that kent recommended made it run worst and the graph was all ova the place. does any body have any ideas why it might be so down on power. the compression is 165 on all cylinders and it has just had the headgaskett done. any surgestions would be helpful |
