Miles' engine is probably making good power because it has loosened up.  These engines seem to get better the more miles you put on them.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

First failure now thou, HG going which at a shade over 285,000. I think this is outrageous so a letter of complaint is going off to Peugeot.Cutting away airbox, scopes etc all have an effect on high and low pressure area's, There's allot of info on this ________________________________________ 306 Rallye Sptint/Race Car, 205 CTI 1.9 8v to name a fewRoad, Track and Race/Rally car preparation to your personal requirements, Full Workshop & Diagnostic Facilities New and Second parts, from Plugs to Turbo's We now also carry out Routine Servicing www.pugracing.com & FB Page, https://www.facebook.com/PugRacing Ebay; http://stores.ebay.co.uk/Pug-Racing-Shop 2012/2013/2014/2019 Class Winners at Gurston Down Speed Hillclimb & Joint overall, Class record too along the way, |

If having a shorter "chopped" "ram air " (lol) scoop sitting under the grill is actually any better, this is how Peugeot would have made it. After all, it's less material they have to mould which may not sound like a lot, but over the 9 year production run of the 306, that would have amounted to a substantial cost saving. For best performance, leave the standard air box in place if you're using the standard manifold. If it's just the noise you want, do whatever. ________________________________________ Ph1 306 GTi 6 | RX8 231 S1 | YBR 125 Cafe Racer | MT-03 660 |

At high speed there is a lot of pressure in front of the fans/radiator. This is a good place for the intake duct.I wouldn't have thought you would get the same pressure in front of a 6" wide duct pointed towards the wind. The vacuum at the intake is going to be way more than any ram setup could force down it anyway. The intake ducting just needs to begin in a position where it can get cold fresh air taken from the area with the highest air pressure. Chevrolet used cowl induction where the intake air originates at the base of the windscreen and travels forwards under the rear of the bonnet towards the intake. They found that the pressure was massive in front of the windscreen and would feed the vacuum of the engine better than non cowl induction. I would say the airflow would be smoother entering the original horn shaped duct than going into one that's had the end sawn off with blunt edges. I think the standard setup is very well thought out and having a performance filter in the standard airbox is a very effective setup. ________________________________________ |

I don't have the notes to hand, but I once hand calculated an approximate gain in bhp an F1 car sees at 180mph from the "ram effect" of the air intake above the driver's head. It was only something like 3%.________________________________________ Ph1 306 GTi 6 | RX8 231 S1 | YBR 125 Cafe Racer | MT-03 660 |

I mean best performance as in Peugeot probably spent a lot of time and money on R&D getting the standard setup to work well because they wanted the car to have more power than rival models which were fitted with turbo's, whereas the home-brew induction kit/modified pipe/bodge/halfords specials make a nice sporty sound so they must be good and don't actually need any R&D on them other than a couple of biased "tests" they carry out (poorly) just so they don't infringe on any advertising standards when they put nice brightly coloured graphs on the packaging... That and several years of in-depth theory and literature reviews because engine design is a subject I very much enjoy and want to spend my career working on. A "ram air" intake scoop on one of these engines with the standard manifold does little-to-nothing at best. ________________________________________ Ph1 306 GTi 6 | RX8 231 S1 | YBR 125 Cafe Racer | MT-03 660 |

Reason I ask is because I don't recall anyone on this forum or any other having a look at it (except Ash and I didn't leave the key with it) and then it was stolen back in June. So either there's been some confusion or someone's got some explaining to do...And for what it's worth the "bodge" comment wasn't intended for you Kev (I thought that much would have been obvious unless you yourself consider yours to be all of the things I described) so don't take that personally. ________________________________________ Ph1 306 GTi 6 | RX8 231 S1 | YBR 125 Cafe Racer | MT-03 660 |

Mind you I quite often travel all over Wales stealing rough old 309's in my spare time Ahh, so you mean this photo of an incomplete conversion then? Well that says it all! Only the world's worst bodge artist could have possibly carried out an engine conversion and had it sat unfinished for a couple of days! [edit] Also I found my notes on ram air. With a few small assumptions on altitude air density and so on, at 100m/s the power gain is something like 6%. So you'll be pleased to know that next time you're sitting at 223mph your F1 style ram air induction mod is gaining you about 10bhp over the book figure.

As I say,it works on my car thanks You stick to your calculations on paper oh wise one I've used three different intakes on my car,everything else exactly the same: 1,induction kit,great noise,crap low down throttle response,worst feeling driving. 2,full standard induction,better to drive than induction kit,hardly any induction noise. 3,as it is now,standard airbox with RamAir cone inside it,resonator removed,snorkel cut.Best of the three to drive by far,with more induction noise. So untill you have real evidence my set-up does not work/make the car better to drive/more powerfull wind your neck in and go do your homework clever dick ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

Judging by the muck all over the bumper it probably also sucks in bugs, road dirt, small pedestrians etc. That setup would be OK on the track but for normal road use I'd stick with something close to the original location. ________________________________________ Cherry Rallye SOLD |

I maintain that the best all round set up is the standard set up with a modified airbox running a decent filter. You don't have to worry about puddles, it sounds reasonable and gives a good sharp throttle response. I've tried and seen lots of different methods and for my liking this is the best all rounder. ________________________________________ See the sheer power and might of the lesser known burrowing owl. |
