Thinking of having a Dave baker (puma racing) big valve head done. Ive got 220bhp an just thinking bout this would it improve power across the rev range? my engine is very camy an you have to work it. I don't mind this but wondering if this will improve power top end but help mid range. I would ask him but I bet he gets it all the time. I hear he's one off the best in the business.________________________________________ 230bhp 205 gti6 |

To be honest the gti6 head flows very well as standard and theres not a huge amount to be achieved when at 220-230 bhp.________________________________________ 2.1 16v 306 Rallye. |

What torque does the engine produce? Who did the mapping for you?________________________________________ 2.1 16v 306 Rallye. |

If you are taking the above advice and going to France, I'd suggest you take €€€€€€€ not ££££££! If you want a good job doing in the UK I'd personally advise you speak to Mark Shillaber. He'll let you know exactly what you can expect to gain flow wise. As others have said, your limits will depend on many factors. I doubt you will see much difference with those cams. ________________________________________ 205 rally car with 2.2 hybrid 6 engine: phase 2 engine build underway. |

Money could be better spent tho rather than trying to improve a head thats not really holding the engine back!________________________________________ 2.1 16v 306 Rallye. |

well wat do ppl do to get another 80 bhp from these engines? i know rpm is increased but surely they have head work. An no i cant just afford to go an get race engine built in one i have to do abit at a time. i run a longman inlet. torque is 157. mikeanics mapped it.________________________________________ 230bhp 205 gti6 |

steel crank and bigger cams, proper exhaust and inlet, more revs.oh and much more frequent rebuilds... you can;t really do this a bit at a time and still run it, you need to get all the parts designed to work as a package. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

Standard exhaust mani is restrictive at 230-240 bhp. Which is also pretty much the limit of where you will get with the cams that are available on hydraulic lifters. You will need solid lifters and more agressive cams to see anywhere near 300 bhp. Which will also require a decent maniflow manifold and 2.5" exhaust, 48 or 50mm tb's and a decent inlet. I shouldnt worry too much about a headline bhp figure, have you seen the torque of the higher bhp pug 1 off engines? ________________________________________ 2.1 16v 306 Rallye. |

Mines 176 lb ft. Hoping to get that up once mapped again as have changed to a maniflow and also 2.5" exhaust. Have seen Sandy produce over 200lb ft from a 2.1 which was peaking at around 230 bhp. ________________________________________ 2.1 16v 306 Rallye. |

that sounds good because i really have too rev the bo***cks out of mine. do you think selling my throttle bodies set-up an buying one of his will make good difference. I run a 2.5 exhaust just std manifold thow.________________________________________ 230bhp 205 gti6 |

It wouldnt be the bodies themselves, possibly just the inlet manifold. But the trumpets themselves can have an effect, some people play with different trumpet lengths when mapping to get the best overall result. I would doubt that you would see much more bhp but it may be possible to get more torque. Would be best to PM Sandy to be honest to see if he would be able to map your type of ecu, and if he can what he would recommend in terms of the inlet / trumpets.________________________________________ 2.1 16v 306 Rallye. |
