The supercharger is any device that pressurizes the air intake to above atmospheric pressure forcing more air into the engine to produce more power for a given displacement. A supercharger is a form of forced induction that is mechanically powered, usually by a belt connected to the engine's crankshaft.
The advantages of using superchargers are:
1) Increased horsepower: adding a supercharger to any engine is a quick solution to boosting power.
2) No lag: the supercharger’s biggest advantage over a turbocharger is that it does not have any lag. Power delivery is immediate because the engine’s crankshaft drives the supercharger.
3) Superchargers produce good power at low RPM in comparison with turbochargers.
Types of Superchargers:
1) Roots Type Supercharger:
This is the oldest type of supercharger, and it is simple and widely used. The roots-type supercharger is known for producing large amounts of boost while spinning at very low speeds. The primary function of this is that it compresses the incoming air before sending it to the engine.
2) Twin screw Supercharger:
They are quite similar to the Roots-type blower as in the basic mode of operation. Compared to the Roots-type blower, the twin-screw supercharger is vastly more efficient since it moves more air inside the engine and is denser.
3) Centrifugal Superchargers:
It is a specialized supercharger that uses centrifugal force to increase the manifold air pressure. The increased pressure allows the engine to burn more fuel, which results in increased power output.

Modern advancements in design of the Roots style Supercharger by companies like Eaton have greatly improved the thermal efficiency of the the design to approach that of the Twin-Screw. The Roots principle is the true "blower", in that it does NOT compress any air within but merely pushes greater volumes of air into the Intake manifold where air-compression can occur. The Twin-Screw is where air is squeezed between the lobes of the screws within the Supercharger to raise compression. So when no boost is required on the Roots, you just have a valve installed that when opened can divert the excess air to atmosphere with minimal parasitic load on the engine. The Twin-Screw is always acting so a blow-off valve is needed to lower the intake charge.

I have a supercharged CTS-V coupe. I recently had headers installed and a larger exhaust system. I noticed that even though power output increased on the dyno the boost pressure had dropped. This is because the restriction on the exhaust system was reduced, allowing for a more free flowing engine offering the same power output at a reduced pressure. I had expected power output to actually increase significantly but I really only gained about 40 HP (540 Wheel Horsepower). I think this is because I am not burning enough fuel to match the increased airflow so next will have to be be larger fuel injectors and fuel pump. Once this is done I can then speed up my supercharger with a smaller driven pulley to get more power. Point here is, as the article stated, just sticking a supercharger on an engine doesn't mean you get a lot more power without changing other parts of the engine as well. In fact, too lean can cause all sorts of engine problems and increasing airflow too far without increasing fuel can cause serious damage to your engine.

@bowez9 Жыл бұрын

Couple issues, Roots do not compress they are just positive displacement. Screws rotors are not identical, one is the negative of the other and the increased efficiency comes from that it compresses and is also positive displacement. Centrifugal supercharger do have lag as they only compress and are not positive displacement, are essentially a belt driven turbocharger (the worst of both worlds).

@needmoreboost6369 Жыл бұрын

What do you mean “The worst of both worlds”? Pro charger would disagree and the on track results in circuit and drag? And any time air is pushed into any engine at any increase in pressure it’s compressed air isn’t it?

We're looking to replace our 2016 1.0 Peugeot 108 in the next couple of years and it has to be small, but with a bit more power.. However most manufacturers have stopped making this segment of cars. It was going to be a 1.2 Kia Picanto, but on paper at least, the added power will be coping with a slightly heavier car. The turbo version has ended production, so it looks to be a two or three year old example. It's GDI too and I don't like going down that route but EVs aside, I don't see any real options (test drives notwithstanding).

Centrifugal supercharges; belt driven or electric suffer from same boost problem found on turbochargers.... when you double the rpm of impeller, boost is not twice as much it's 4 times as much. Boost increases exponentially, 2 times faster = 2 squared = 4. Roots and twin screw have a linear boost curve. Twice the rpm = 2 times more boost. The electric supercharger has great promise. It can deliver precisely the exact level of boost managed by engine computer. Small surge storage tank can capture over pressure and store, rather than venting to atmosphere.
