Superchargers VS Turbos – Whats the Deal and Which is Better?

Turbochargers VS Superchargers

Welcome, brothers and sisters. We are gathered here today to set aside all of our differences and unite as one to genuflect before the Altar of Boost. Now like with any religion, there are different sects and congregations with their own differences and creeds. Whether you follow the Temple of the Turbo or the Shrine of the Supercharger, we are all children of the Patron Saint of Boost (praise be).

So whether you’re wondering what exactly the difference between these two methods of forced induction are, or which is better for any given purpose, we’ll get into the how, the what, and the why of that juicy, glorious boost.

Forced Induction, the Short Story:

The point of a supercharger or turbocharger is to cram as much air into the cylinders as possible. More air allows the ECU to add more fuel, more fuel means more boom, and more boom means more smiles. Who doesn’t like smiles?

The TL;DR on the difference between the two is this:

Superchargers are intake air compressors that are belt driven off the crankshaft.

Turbochargers are intake air compressors that are driven by exhaust gasses.

Now the Long Story:

The amount of power your engine can make effectively comes down to how much fuel it can combust, and how fast it can turn that heat energy into mechanical force. Oxygen needs to be present in order for fuel to burn, and that mixture between air and fuel is a very specific ratio. The most efficient mixture for gasoline engines is 14.7:1 air-fuel, this is called the stoichiometric ratio. At this ratio, the fuel has enough air to burn completely (under ideal conditions).

A lower air-fuel ratio is called running rich, because there is more fuel to be burned than there is oxygen as the accelerant to burn up all the fuel. Running rich is less fuel efficient but in some cases can produce more power, and tend to run cooler. A higher air-fuel ratio is called a lean condition, where there is more air than the fuel needs to burn. Running lean is more efficient, but means the engine tends to run at higher temperatures. There are other side effects of either, but those are for another time.

Compressing the air before it goes into the cylinder allows the ECU to add more fuel to keep up that ideal air-fuel ratio, giving you more power potential. Now let’s get into a few different methods of getting that done.

Pros and Cons of Each:

Though both are common to see, turbochargers are the decided favorite of manufacturers for a few reasons. In the muscle car and old school crowd, superchargers seem to be the favorite. So why is this? Which can make more power? Which is better?



  • Linear power delivery with no lag
  • Easier to install in the aftermarket
  • Less likely to interfere with smog equipment and be street legal
  • More power at lower RPMs than a turbo


  • Parasitic drag on the engine makes them less efficient
  • Less potential for software tuning



  • By making use of otherwise wasted exhaust gasses, turbochargers make power more efficiently
  • Big power gains can be made with software tweaks alone


  • Bigger turbos require time to spool up creating turbo lag before power hits
  • Complicated to install in the aftermarket
  • Not many bolt-on kits available

My Verdict:

I carry the banner of the turbo.

The overwhelming majority of R&D dollars from the auto manufacturers have gone into developing and manufacturing turbochargers. The reason? Well, mainly efficiency. Take Ford’s EcoBoost line of engines as an example of smaller displacement turbo engines edging out the classic V8s of old.

Say what you want about Ford, but if there is one thing they do right, it’s their pickup trucks. Messing with the formula of the best selling vehicle in the country for the past 30+ years is not something that any manufacturer would take lightly. Yet Ford replaced the V8 with a twin turbo V6 for the top-tier engine in the F-150. This allows them to hit higher EPA ratings for mileage while making more power than ever before.

Garrett Turbochargers, the gentleman’s choice

Case in point, you can get a 450hp version of the 3.5 EcoBoost in the Raptor or Limited trims now, making them far more powerful than even the old Lightning models were, and second in the running for most powerful pickup truck ever made (that title goes to the Ram SRT-10 with the engine out of the Viper).

Here’s a more detailed comparison:

Ram SRT-10
Engine: Naturally-aspirated 8.3l V10
Horsepower: 500
Torque: 525 lbs-ft
MPG: 9 city, 15 highway

Ford F-150 Limited
Engine: 3.5l twin-turbo V6
Horsepower: 450
Torque: 510 lbs-ft
MPG: 17 city, 22 highway

Now whether customers will actually see that 22mpg in the real world is another story, but it should be noted that in Doug Demuro’s review of the SRT-10, the MPG readout was displaying 5.7 mpg, so I would take any number with a grain of salt. The point is that turbochargers allow manufacturers to see big power numbers that don’t come with the same mileage penalty that they used to.

You do, of course, still see a few of superchargers on the market still, GM makes good use of these on the Camaro and Corvette, the ever-present Hellcats sport superchargers with more displacement than a Honda Civic’s entire engine, and even the turbo-obsessed Ford threw a supercharger on their new Shelby GT500. Notice, however, that these are all applications where fuel consumption is not exactly a priority.

So now you can tell your grouchy uncle there actually is a replacement for displacement. No matter if you carry your shield in the name of the turbo or the supercharger, we do it in the name of Boost. Praise be.

What do you think? Do you disagree? Drop a comment below!


  1. Interested in a Turbo Charger fir my 2019 Dodge Challenger stock 5.7 Hemi R/T with the Shaker hood. Also recommend brakes for maximum stopping power Ceramic or other?

    • Hey George,

      For your Challenger I would recommend a supercharger kit over a turbo, as there are a few complete bolt-on kits that you can install yourself, VS a turbo which would require quite a bit of custom work to fit. For brakes I would recommend EBC YellowStuff pads, the EBC Sport rotors, and any good DOT 4 fluid. That should set you up nicely to handle the extra power.


  2. I have a 2016 f-150 4×4. It is a twin (turbocharged most excellent vehicle. Has plenty of power in the top end. I drive it like a pawpaw. Whatcha is unfamiliar, partly because I know it’s there. Not a mustang gt, but it is there when needed if the plugs allow for the boost. Why do these trucks use spark plugs ? Do they not build the plugs like they used to, or something else. I have never ever had to change plugs in the timeframe that I have to with this truck

    • Hey Josh,

      Hmm, is it always the same plug or different cylinders each time? That should be a warranty issue, but I wonder if changing out all 6 of the OEM plugs for a different brand would help./


  3. Chipping the engine is often an “easy”, convenient, and quick way to get more HP.
    I’d like to see you discuss this after market option as well, + and -.

  4. I’m Team TURBO…. no doubt all that you said is very true. But you fail to speak of the Growl of the Supercharged and that Distinctive Whirling of the Turbo, which the latter is a much lower in sound (of course) of that when Chuck Yeager barrier breaking TURBO-JET engine beast 1947 .

  5. Hello there fellow car meddler,
    I recently bought a 2020 venue se(manual trim) for various responsibility reasons, but that doesnt mean I wont make irresponsible aftermarket choices hahaha! Also its an interesting challenge to make this car a good looking tuner. (Biggest challenge is finding parts that fit…)Any recommendations for turbo kits or superchargers for hyundai engines?

    • Hey Carl,

      Congrats on the new ride! Unfortunately it doesn’t look like we have much in the way of performance parts for you so far, with this being a new CUV on the market. Couldn’t find a tuner for these, much less a turbo or supercharger kit. Maybe in a few years these parts will start rolling out!
