Does a bigger carburetor mean more power?

The smaller carb has increased air/fuel velocity at low and midrange, giving better throttle response. A larger carb will flow more air/fuel at higher rpm and give more top end and higher peak hp.

Which is better EFI or carburetor?

EFI systems are more fuel-efficient than carbureted engines. This is because the electronic system constantly adjusts the air to fuel ratio to ensure that optimal levels are delivered. Carbureted engines, on the other hand, may deliver an excess fuel to air ratio, which can lead to more fuel consumption.

Do any cars still use carburetors?

Fuel injection technology has largely supplanted carburetors in the automotive and, to a lesser extent, aviation industries. Carburetors are still common in small engines for lawn mowers, rototillers, and other equipment.

What makes more power carb or EFI?
