thanks for info, much clearer now

 

Don't forget a carb requires a venturi to function, so optimal carb vs optimal efi, efi will always win. venturi == restriction. Theres also the issue of altitude, carburetors will not correct for this so if you drive through mountains and valleys your car will run like **** with the carb. Guys with carbureted bikes that go on road trips through largely varying altitudes have to bring spare jets along and tune the bike to run well in the mountains, right after they adjust their chains heheh, nutty people.



if yer short on cash though slapping a rb carb/manifold setup on a fc with otherwise stock intake will net some significant gains if it's tuned well enough, but a bunch of negatives come with that.

 

the TWM TB requires an aftermarket ECU, right?

 

it does , unless u want to put afm in front of it, or make some sort of a hack to have a map sensor but keep teh stock ecu with some loig circuit

 

afm is a big restriction when goign with the twm, that woudl kinda kill teh point of the ITBs

 

duh, I just didn't think of that. thanks!

 

Carburetors aren't terribly difficult to tune. The real challenge you people face when trying (and I use that word loosely) is ignorance. It isn't necessary to adjust a carb when the temperature fluctuates 10 degrees. I've been using one regularly for quite some time, and I've barely touched it. A choke that functions properly handles the cold start problems you think seem to exist. Knowing how to turn an electric choke on and off will help greatly.
