Which offers more performance, more reliability, and overall drivability? Fuel Injection or carburetors? In this we will find pros and cons of each, and determine which one is the overall better of the two. I have always wanted to investigate the advantages and disadvantages of carbureted versus fuel injected engines. I really enjoy things that involve automobiles and engines, and as times are changing, are they truly better? Or are the old ways the best ways? As I am in my senior year I have recently purchased myself a truck that is road legal, and is a carbureted truck as well. And being that I could be in the market for a newer of different vehicle soon, I would wonder what is a better fit for a student like myself where I prefer to most …show more content…

The 4 barrel was common and muscle cars, and race cars. The two biggest and most common manufactures of carburetors were Holley, and Carter. Very common to see either of these two on GM’s, Ford/Mercury, and Dodge/Chrysler group. Barrels on carburetors are a small tube like cylindrical area in the carb that mixes the fuel and air for the motor. Most commonly more barrels mean more cubic inches in the motor and more horsepower. The other main parts in carbs are the jets, which squirts fuel into the combustion chambers of the engine, and the float, which manages fuel inside the carb. However where would you see carburetors? Really only today you would see this in the “Hot Rod” and or car scenes, where the older American or domestic muscle cars are the main center of the action.

Carbs are found most commonly in the old muscle car scene as they are simple and cheap to work on and they are the simple backyard mechanics friend. The average car guy will very …show more content…

The biggest question being, of course, who makes more horsepower? And the question really depends on the application your considering.

Where in the same case having EFI, nothing needs to be done an if it did need to, it can all be done by computer. Also the fact that the famous American sport NASCAR had been using carbs since they began in 1948, it wasn’t until 2012 they finally said goodbye and was replaced my EFI. The real only way to make big power in today’s scene is with boost. Which involves turbo or superchargers. Both can be set up with carbs and EFI, but tend to be more tunable with EFI. As well as today if you want to stay as an all motor runner, and use carbs, enormous power can only be made with a four-barrel carb, and if not the famous MOPAR “Six pack” will be used being three two-barrel carbs on top of the engine. And some drag cars still use carburetors today due to their simplicity, reliability and cost effectiveness. But in the majority of cases to be able to run your American
