nope, dual carbs add about 15HP to every motor of the same displacement over the single carbQuote:

Dont just slam your hood down to close, some models have different clearance between the hood and the airbox...Quote:

Michael, the 94 breeze is a dual carbi... its the 1.5 litre d15 engine rite?
i know it's a 1.5 carby of some sort...
not sure if it's d15....
is you airbox mounted horizontally under your hood, or is it mounted vertically (upright) next to the firewall at the back of the engine compartment? And it is a D15...Quote:

it wouldn't be a good idea to remove that lid altogether would it?
OK, then you do the old ford trick... you take out the filter, put it on another flat metal/plastic plate, trace the outline of it with a marker, cut out the metal along the line you traced, drill a hole for the wingnut bolt, put your filter back in the airbox, and tighten it down with the new plate on top of the filter...Quote:

No, you will only be sealing the top of the filter over the carb throat, not the actual filtration side where the paper is... that would be exposed to open air, which can now suck in air from right around the exposed sides... when you trace the filter, you trace it while lying FLAT on the metal plate, with the papaer filtration exposed on the sides. Since the new plate will not make contact with the lip of the airbox, the filtration side will be open to the athmosphere...Quote:

would i have to use metal?
would wood be fine?
so how much of an increase would i get if i did that and also a chrome pipe with and air filter attached?
lol, some guys have used wood, but thats a bit ghetto mate... metal or sturdy plastic plate that you can paint nicely and will be strong enough to withstand the wingnut and the heat will be great. carbs dont work like FI, so a pod filter and chrome pipe will not work as well as a carb breathing from 360 degrees..Quote:
