Can you convert a carb to EFI?
A fuel injection conversion replaces a carburetor with a fuel injection system. There are fuel injection conversion kits that make the entire process very easy. Older cars have carburetors, but electronic fuel injection (EFI) offers greater fuel efficiency and improved performance.
How much does it cost to switch from carburetor to fuel injection?
A newly remanufactured 725 cfm Quadrajet carburetor will set you back $330. A 750 cfm Holley Street Demon carburetor will cost you $347. Finally, depending on the fuel-injection kit you choose, you can expect to dish out anywhere from $1,000 or more.
Does EFI make more power than carb?
Warren Johnson: Properly tuned, carburetors make more peak power than EFI in a Pro Stock engine. A carb’s pressure differential atomizes the gas a lot better than spraying fuel through an orifice. But EFI has a broader powerband and superior cylinder-to-cylinder fuel distribution.
Why is EFI better than carburetor?
With EFI, fuel delivery can be tuned to match driver demand. While carburetors can be properly tuned to offer precise fuel delivery, that tune is not able to alter for outside effects. In other words, they cannot account for and adjust for changes in air or fuel temperature or atmospheric pressure like EFI can.
Can you use EFI distributor with carburetor?
Due to the fact that the E.F.I. distributor has no advance you will need the above distributor when switching to a carburetor. You will also need a new fuel delivery system (you can just install a pressure regulator or you can get a new low pressure pump).
Is fuel injection better than carburetor?
While the carburetor may have been around for over a century, fuel injection is a clearly superior alternative, delivering better power, fuel economy and lower emissions.
Is EFI better than carburetor generator?
Since EFI engines deliver air and fuel with better accuracy than a carburetor engine, they generally produce fewer emissions to go along with the improvement in fuel efficiency. Atomization of fuel also helps burn the fuel more completely.
Are fuel injectors better than carburetor?
Which is faster fuel injection or carburetor?
The better fuel efficiency is a big bonus too, but EFI can also offer slightly more power over carbureted systems, along with a faster throttle response. Finally, fuel injection systems are usually very reliable, and require little to no maintenance.
How does the sp383 EFI system work?
The SP383 EFI incorporates a port-style injection system, with the injectors plumbed in a carburetor-style intake manifold and the throttle body mounted in the conventional position of the carburetor, which allows for a traditional air cleaner and a classic appearance.
How much horsepower does an EFI kit add?
Most aftermarket EFI kits are designed for naturally aspirated engines making less than 650 hp. The size of the injectors included in the kit (typically four), the airflow capability of the throttle body itself, the fuel pressure, fuel pump, etc. determine how much horsepower the engine can produce.
Can you convert a big block Chevy to EFI?
When converting to an EFI system that offers the ability to manage the timing, you need to choose ignition components that are compatible with the system to allow it to do so. I used these MSD components when converting the big-block Chevy in my Olds to EFI.
What happens when you convert your car to EFI?
This means that you’re also running a high-flow electric or mechanical fuel pump. As you convert to EFI, you may need to replace that fuel pump with a high-flow electric fuel pump capable of much higher operating pressure.
