you don't need an aftermarket crank for 280, but you do need to build it well.280 from an XU is more like 10k+ ready to run, easily looking at 6k in parts on their own. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

I thought that the original crank wasn't much good over 8k rpm for extended periods Mei? would have said for 280bhp would need to be revving to 8.5-9k ish?________________________________________ Super high boost Completed, destroyer of gearboxes and 160mph club |

I've not seen curves etc but matts (pug1off) headline figures aren't that far off a maxi, how you can call that s**t I don't as to me that's quite impressive especially considering the amount of r+d that would of gone into building a maxi lump. Credit where credits due imo.________________________________________ Ryan |

Trouble is its a forum and people are biased either way but I totally agree at the end of the day I've seen cars running with pug1off engines and sandy brown engines and tbh they all look fantastic and no doubt they were all made for different purposes etc |

Supercharge to over 450bhp, no need to worry about revving over 8k then.  Also no need to gas flow head, buy different cams etc. You're all good to go.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

Play a different tune Stan! For people that want to actually compete in there cars NA is the only option unless you want to race in the open classes which have everything from radicals to 1000bhp evos in them, which make a 450bhp 306 look a bit silly. On a circuit a high revving, high power engine is what you want, because you can learn what gear to be in and when and keep it on song all the time, so in that case a 300bhp 9k rpm engine is going to be quicker than a 8krpm 270bhp engine because you're using the power, not the torque. However to drive an engine like that does cost a lot in rebuilds, and its f**king tiring to boot, and if you drop off cam you can watch the entire field pass you whilst you change down a gear or wait for it to pull again. For less energetic drivers, and generally speaking rallying too, a torquey engine isn't going to be much slower but will be easier to drive as the revs can drop a bit and the engine will still pull, hence often someone will find they are quicker with a torquier (sp?) engine than with a high rpm engine as its easier for them to drive and keep in the power zone. That is my theory anyway, and I'm usually correct. ________________________________________ Oulton Park in a BTCC 306 vid 1Oulton Park in a BTCC 306 vid 2 Lap of the 'ring |

Nope but to be fair I'm talking about for track use on occasional use in the supercharged cars it has been proved fine. but for high power NA where you sit at high revs 90% of the time I'd be concerned using the standard crank there must of been a reason all the Longman engines used steel cranks? not a cheap option  ________________________________________ Super high boost Completed, destroyer of gearboxes and 160mph club |

I'm running a standard crank developing 320ft/lbs and 454bhp, although it's obviously boosted.However, it still revs to 8k, which I feel is enough. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

No i haven't seen a failure but seems an excessive waste of 2k to put them in if there's no need.Stan i know what you're saying and agree the supercharged conversion revs to 8k but you don't have to sit there all the time to feel the power you prob make 280bhp at 6-7k so no need to wind it right round. I did ask My engine builder and he said no need for a steel crank! but that's supercharged not NA. ________________________________________ Super high boost Completed, destroyer of gearboxes and 160mph club |

280bhp N/A vs 450bhp charged. Which would be more fun to drive and which would feel faster?  ________________________________________  |
