is anyone running weber carbs and cams as oppossed to throttle bodies and cams.are they just as good at uping the bhp. im thinking of doing this as i can not afford tbs and managment and the carbs seem like a cheaper option. what sort of spec and gains are to be had i dont want anything wild, somewhere around 200 bhp mark would be nice. any advice ? ________________________________________ 178bhp 205gti6¼ mile in 14.2 |

Matt Holley used to run carbs on his 2.1 gti 6 engine, then changed to itb's. Trouble with carbs is to get them set up 'well' you are really best to run an ignition ecu. I think tho that once youve forked out on the carbs, manifold and other bits needed, got an ignition ecu and had it mapped you may as well have gone that little bit furthar with throttle bodies. You will never get it to run aswell, which if used just as a track car might not be so noticable, but if used on the road it certainly would be!________________________________________ 2.1 16v 306 Rallye. |

if your going to run carbs you need a ignition ecu for a gti6 engine ideally, the dizzy converters are pants and youwill loose everything your trying to gain. as above once you've bought the full carb setup, ignition ecu, wired it up and had it mapped might aswell of gone down the TB route. try pick up a second hand set of satchell thottle bodies complete with inlet and trumpets, just as good if not better than jenveys and dont carry the same price tag. ________________________________________ 230 hp 2.1 16v XU 205 rallye on jenveys Project thread here309 3dr K20 Type R |

yeah i know what your saying, but second hand webers go for about £300 were as tbs are about £600.Then there is management, say omex at £600 plus fitting. i dont know how much an ignition ecu is but i imagine its half the price. ________________________________________ 178bhp 205gti6¼ mile in 14.2 |

Colins bodies are £650 new, DTA S40 is £500 new, ignition only is £400 iirc.How did you get 178 already? one massive plus point of well mapped bodies is that they will potentially use less fuel, whereas carbs will 100% use lots more fuel. ________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

Get the Jenvey linkage, when it comes to balancing it all up and mapping the RR operator wont thank you if he has to p*ss about with some fiddly homemade Meccano shite. It will save you money in the long run and be safer as the mechanisim is very unlikely to bind and jam your throttles open.________________________________________ R H Davey Welding Supplies.

Are they the esprit ones which i'm sure i've seen mentioned somewhere? Would they be running 8 injectors setup? Sorry for so many questions, just read that i'd probably struggle to get more than around 50bhp per cylinder with 40mm bore TB's, i'd be hoping for a bit more than that with the cams i've got and the engine which i will be building eventually. ________________________________________ Goldie the track car. |
