| Post subject: | Cold air to the Weber |
HEy Guys, I was wondering if anyone had developed a way of getting cold air from the front of the bay to the webers, or SU's if your that kinda person. Ive seen a picture of something like a carbon fibre cone, collecting cold air funnelling it to the back but i can't seem to find it. Any ideas, pictures or links? Thanks, Bill |

Some people say it is not needed. The air temp does not change that much between the grille and the carb inlet because the air is not passing through a radiator and collecting heat like most cars. It heats up when you are stationary but while you are moving it is fairly cold. Then there is the problem of the air being too cold and freezing the carby. Down this way I have to run heated air for about half the year to stop the carby from freezing.. |

Probably because of the front radiator. |

I reckon cold air is a waste of time as Morris said. If you have read Visard and want a long intake for mid-range torque you could try something like mine. It is a bit backyard but it works suprsingly well and was a million times better than the pancake K&N that I had on there and about 100x better than the stock donut. If I was making it again it would be a slightly smaller diameter and maybe not povo plumbing pipe and an asparagus can coverend in fibreglass

meeni, this was what i was after. interesting that the air can be too cold, obviously there would be a saturation point somewhere but i would have thought that was icy temps. I just thought that the extractors are putting off a lot of heat, perhaps ill wrap them first. Bill |

JanSpeed (SU or Weber): 
DBilas (german manufacturer, rare piece of kit): 
But in both cases I belive reduction of intake noise was the main concern 
Cheers, Jan |

Needs to be 500 metres closer to sea level

If your that keen for the extra power it MAY give get your car tuned properly to a specification. Or chuck a 7 port head on it with individual throttle bodies, a decent ems and then itll tune itself hundreds of times every second. Pretty much what im saying is a carby is not a precise tool, it can be tuned to give excellent results, but flexibility is not its strong point. |

Its not the flashy carbon fibre like the miglia but its still sexy 
i know its in a Sprite/ midget but you get the idea .. i was thinking of making one up for myself .. Beanie |

we actually did a "back-to-back" time-trial test at Lakeside with my 1500cc green "S" , with & without the cold air feed & it was definately quicker with it,,, seemed to pull far better mid-range & up-top as well but hey, it wasn`t an "exact-science" , it was just a test , on the track that i know very well & can do very consistent laps, & against the watch, but it was a test & it seemed to work edit--> sorry no pics of it , but all it was a Fuel Funnell zip-tied to the grille & fed air to a plastic ice-cream bucket type thing around the weber air-filter |

Steve "Justminis" has a great cold air box set up on his green car. We need him to post a pick. |
