Webbers?

What exactly do tripple webbers do?

Apart from burn a shit load more fuel? Is there a huge performance increase with them, or is it more of a sound thing?

Yours,

Hi Mark,

Badly set up webers "burn a shit load more fuel"

Well set up webers can be "reasonably" economical

Triple carbs of the weber variety (multiple stage jetting) allow more precise metering of the fuel at high flow rates than carbs such as SU's etc which have a variable jet. Plus triple webers are effectively 1 carb per cylinder (3 x pairs) so a greater volume of air can be throughput. Bolting on a set without other mods will do little on its own but used in conjunction with say a nice ported head, fast cam and decent exhaust then good HP gains and top end performance will be possible.



Its all about using components to complement each other, not individually.

They also sit on what is called an isolated runner inlet manifold, so the one carb' / cylinder is completly independant from the others and the flow does not get affected by the turbulance caused by the other cylinders moving up and down (as you would with a siamesed inlet manifold).

Cool! Thanks chaps, every days a schoolday!

wasn't it reputed that the two best inlet manifolds were nismo/cannon... these were "siamesed" i think?
