floody Regular Registered: June 2002	Re: efi vs carby Mon, 07 October 2002 05:17 In my experience, good carbies, such as webers, dellortos, mikuni flatslides etc can be just as good as injection for power, sometimes better, but, heres the thing, they will only be better or as good in a certain revrange- you can tune your carbies to give for example 1.the same top end power,or 2.same bottom end grunt, but either will compromise the other, due to the fact that the tuning- jetting, float levels etc- is basically static, where as an efi system can adjust the way and amount of fuel being delivered far more widely. You can also theoretically set up a carby for just as accurate mixing as efi, but again it will only be at a specific rev/load point, where as with efi you can have the ability for constant adjustment according to load, temperature, barometric pressure etc. Carbies operate in a very narrow band of operating conditions for peak efficiency, and can't compensate for most of the things that efi can. And, due to changing engine temps and other factors, its harder to accurately tune a carby,even on a dyno, but it can be done. So If its a constant high rev application,or a setup where all out power is to be chased, well, there may be little difference. however if a smooth torque curve or general driveability is a factor, and , really, when isn't it, efi will be best. Cost comes in too, of course- I'm working on a 4age powered something (chosen the engine, unfortunately not the car...probably escort mk2) which will more than likely use twin webbers, dell ortos, or hopefully mikuni flatslides. Its simply a dollars thing for me though, any of those will outflow the standars setup, but will have nothing like the driveability and sacrifice the power in some areas. Thats my two cents, I hope I was on the right track.... cheers, floody [Updated on: Mon, 07 October 2002 05:20] [Report message to a moderator]
