Injection vs. carbs

Is there any big HP gains from using one or the other? i assume carbs are easier to work on then MPI or DI fuel rails. How would if effect forced induction as well? Supercharges seem to benefit due to the straight downwards flow from the intake to the centrifuge straight to the carburetor.

Properly tuned port injection will always make more power with better economy and better emissions than carbs.

Properly tuned DI will do those 3 things better than port injection.

I personally prefer port injection as the simplest to work on and service.

intake manifold design makes more difference than carb or injection.

they all behave very differently. an engine with webers like this, has no plenum. it means that UNLIKE a 4bbl each cyl sees only one venturi.

so it can get away with a bigger cam and so on, and act "tamer"

a 4bbl intake, single plane, means each cyl can suck from all 4 venturi at the same time, giving it a good breathing.

Thank you for your post, In your opinion what would be the most powerful of the tree options? Im not worried about emissions or economy due to the laws in my area involving older cars.

really depends on money and goals. i personally like a flat plane v8 with webers
for that sound, who cares about speed when it can sing?

I can agree with you on that

Taking what you said would a supercharger (take a roots for example) overcome the more restricted intake manifold? Or would it be better to leave the throttle response at a good rate with NA?

Port injection will make more power than the carb, DI more than port - ALL ELSE EQUAL.

Take a car with a stock ecu map and a shitty intake, put a ram style manifold on it with a free flowing carb and it might make more power. Give the port injection a similar manifold and ECU tuning, it will beat the carb every single time. DI wins over port via, directly injecting the fuel. This cools the combustion charge, and very evenly distributes fuel. DI tuning is much different, since you can run more timing and (if applicable) more boost, due to the cylinder cooling effect.
Carburetors are "simple" to the average joe. To properly tune a carb, you need an AFR gauge. Tuning it to run fine, start decent, and get acceptable economy can be tuned by the seat of the pants, MAYBE a vacuum gauge if you want the best you can get. Nothing beats knowing the true AFR though.

Yup I like carbs for the sound and ease of backyard tune.

How do carbs sound different? Say you have a fuel injected engine and carb swap it, how will it sound different?
