I KNOW i saw in a thread what TB fits the S16 manifold but has a larger diam?, have searched but canīt find it.Remember something about one of the V6 ones, but not which one. ________________________________________ Member of Peugeot Sport Club Swedenhttp://www.peugeot-sport-club.com/ My son: http://www.youtube.com/watch?v=jzjSBKkMHDA |

The D8 V6 one is the same casting as the GTi6. No idea on the D9, or in fact how it works being fly-by-wire. ________________________________________ Nothing to see here |

Maybe it was the same casting as the GTI6 one then, although i wouldnīt belive a larger TB is whatīs needed on the GTI6 engine, itīs quite large from factory really.The S16 one is quite small though, or on the limit, for itīs power output you could say. ________________________________________ Member of Peugeot Sport Club Swedenhttp://www.peugeot-sport-club.com/ My son: http://www.youtube.com/watch?v=jzjSBKkMHDA |

Can you not just use a GTi6 inlet manifold as a whole instead?________________________________________ Nothing to see here |

Could, but the amount of work needed to make it run well would be wast, the fuelmap is way out for a GTI inlet, nothing matches compared to the acavsystem really, and my acav is working just as sweet as it possibly could  .So i just wanted to stick a larger TB there, so itīs not so restrictive around the "mx hp rpm" area. The stock unit on the manifold is really veeeery small. ________________________________________ Member of Peugeot Sport Club Swedenhttp://www.peugeot-sport-club.com/ My son: http://www.youtube.com/watch?v=jzjSBKkMHDA |

They aren't the same as the Mi16 TB - sure they use VR6 TBs to make those bigger?! Welshpug probably knows - drop him a PM ________________________________________ Nothing to see here |

I belive the VR6 ones are used for the old XU9J4 manifold really. ________________________________________ Member of Peugeot Sport Club Swedenhttp://www.peugeot-sport-club.com/ My son: http://www.youtube.com/watch?v=jzjSBKkMHDA |

Ah right ok, too many manifolds... I've never owned those two engines hence my lack of knowledge.Are you running different cams at all? ________________________________________ Nothing to see here |

Nope, nothing, still all through standard engine, just replaced the injectors for more modern ones which isnīt really a mod, more of an upgrade since a lot has happened with injectors since 1994.But that is another story  Iīll sort with a "mildly" more aggressive intake cam sometime in the future when i sort the headgasket-oil leak, the standard XU10 oil leak place which usually doesnīt get much worse over time either. VERY common XU10 issue, especially here in Scandinavia with cold winter starts and all that. The car is really getting a chassis upgrade first before i start making it more poky. Iīm just gathering information right now, and i really saw something in a thread i canīt find now..., about there being a slightly larger TB that fits easily on the manifold. ________________________________________ Member of Peugeot Sport Club Swedenhttp://www.peugeot-sport-club.com/ My son: http://www.youtube.com/watch?v=jzjSBKkMHDA |

what injectors did you fit?if they were a different CC to the original ones you need a remap straight away. as for whether you actually need a bigger throttle body I can't answer that directly, but I do know that nobody has posted proper back to back results of fitting a gti6 inlet with its larger throttle body to an RFY engine. it is quite a bit smaller, but you have to remember that the port in the manifold might be the same size, so it would be pointless to fit a larger throttle body. gti6 one will not fit directly as it is a 4 bolt pattern, where the RFY is a 3 bolt, of course an adapter could be made easily. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

Not larger, but newer injector type that atomize better, donīt get hangup on that part , that is a quite complicated area to explain.Iīll just have to look into the TB area myself. ________________________________________ Member of Peugeot Sport Club Swedenhttp://www.peugeot-sport-club.com/ My son: http://www.youtube.com/watch?v=jzjSBKkMHDA |

How big is the throttle body on the S16?Bearing in mind my old heap is making 100 horsies on a 34mm body with a great big dirty single point injector slapped in the middle of it.... ________________________________________ - Bespoke rollcages/additions/adjustments.

I understand that fine yes (re-injectors)try this http://www.revtronix.com/tech/calculators/throttlebody I have no idea what parameters they have used to determine the results though. I can measure the t/b later ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

Bit of german engineering there? A bit OT, but the TB from the 80hp version of TU3M found in some 205/AX/BX is 40mm and can easily be bolted on there. The 34mm TB is VERY restrictive on them, not shure if that engine was ever sold in UK though, it is in practical a low-compression TU3S with Monojetronic, NOT the same as the 75HP TU3M, but they share the same name....., itīs wastly common here. Used that 40mm MonojetronicTB on my previous 106 1124cc with ported head and some other stuff, was a funny little machine that pulled well at high revs. The partnership between TB size and plenumvolyme is a critical factor to be ONT again. With a smaller plenum you get higher pulsation through the TB, which means it needs to be able to handle largeer flow accelerations to not restrict flow, but with a larger plenum volume the flow is more constant and then you can use a smaller TB with good results. TB should never be too big, just big "enough" to be shure itīs not restrictive. I havenīt calculated yet, and my questrion in this thread is more like... as said before to see if there is one that bolts physically to the inlet. ________________________________________ Member of Peugeot Sport Club Swedenhttp://www.peugeot-sport-club.com/ My son: http://www.youtube.com/watch?v=jzjSBKkMHDA |
