How Much Horsepower Does a Whipple Supercharger Add?

How Much Horsepower Does a Whipple Supercharger Add?

Horsepower is a major factor when measuring a car’s performance. An increase in horsepower will make the car go faster among other benefits.

Using a Whipple supercharger which is a type of supercharger is one way to increase a car’s horsepower. However, it is important to know that the power produced by the Whipple supercharger varies. So, how much horsepower does a Whipple supercharger add?

A Whipple supercharger adds between 300hp to 1200hp depending on the size and how much power you want.

What is a Whipple Supercharger?

A Whipple supercharger is a type of supercharger that ensure the engine gets a steady supply of compressed air needed for the right mixture of fuel and air. A mixture of air and fuel in the right proportion improves an engine’s performance.

Whipple supercharger is an aftermarket addition to an engine in order to increase horsepower and torque. It can be used in diesel or gas engines.

Whipple supercharger varies in size and power and is designed for specific engines, therefore, if you want to get a Whipple supercharger be sure to get the one that is specifically designed for your vehicle.

If you are using a supercharger you can be sure to get an estimate of a 30% to 100% increase in horsepower.

How Much Horsepower Does a Whipple Supercharger Add?

How much power a Whipple supercharger will add depends on how much power you want, the size of the supercharger, how far you want it to go, and the type of vehicle.

It also depends on the build of the supercharger, however, if all is right in the fuel system, exhaust, and tune and a 20psi pulley is on the right engine you can b sure to get 1200hp.

Using a Mustang GT as an example, a Whipple supercharger can add 300hp. Therefore, it is safe to say the Whipple supercharger is able to add between 300hp to 1200hp.

How Much HP Does a 3.0 Whipple Supercharger Add?

The 3.0 Whipple supercharger is capable of adding an extra 100hp to the average 1000hp a Whipple supercharger can add originally.

The absence of a jack shaft in the 3.0 Whipple supercharger has increased the maximum RPM which in turn boosts and increases the horsepower.

We can therefore say the 3.0 Whipple supercharger can add 1100hp to an engine all things being equal. The 3.0L Whipple supercharger is an improvement on the 2.9 Whipple supercharger.

How Much Horsepower Does a 2.9L Whipple Supercharger Add?

The 2.9L Whipple supercharger is capable of adding 1000hp which is 100hp lower than what the 3.0L Whipple supercharger can add. It can also add as low as 577hp at 19psi.

2.9L Whipple horsepower has the capability of adding between 500hp to 1000hp.

What Makes More Power Whipple or Procharger?

In order to tell which makes more power, whether the Whipple or Procharger we will first consider the similarities and differences between this two.

The Whipple and Procharger are similar in that they have the same function which is ensuring the flow of air into the vehicle thereby improving the engine’s power and performance.

Despite the similarity in function, they both have different parts and units that work differently in order to supply air.

A Whipple or Whipple charger is said to be able to control the amount of heat present in the air passing through the engine intake manifold. Therefore, the power added when the Whipple supercharger is in use is dependent on how cold the airflow is.

The Procharger on the other hand must have cold intake air in order to maintain the boost pressure level.

Major differences between the Whipple and Procharger are;

  • Irrespective of the RPMs, Whipple will perform excellently but Procharger doesn’t do so good with low RPMs
  • Whipple is suitable for street driving and drag racing while Procharger is suitable for daily driving.
  • Installing a Whipple takes longer time than a Procharger is being installed

Now talking about which of the two chargers makes more power, the Whipple makes/produces more power than Procharger. This is a result of the size of its impeller, the Whipple impeller is 71.5mm while the Procharger impeller is 65mm. Owing to this estimated 10% difference in impeller, the Whipple produces more power.

Pros of Whipple Supercharger in Cars

Of the type of superchargers, Whipple is said to be better, and for good reasons. Here are some advantages of the Whipple supercharger

1. Increases Horsepower

This is an obvious advantage of the Whipple supercharger. The presence of the supercharger in a vehicle brings about an increase in engine power, increase in acceleration and the vehicle becomes faster.

An increase in horsepower is a good measurement of an engine’s performance.

2. Power is Maintained Even When RPM is Low

With the Whipple supercharger, you can be sure to have enough horsepower even when the rpm is low i.e. the vehicle is not moving fast at a given time.

3. There is no Turbo Lag

When a Whipple supercharger is installed in an engine, there is usually no delay between when the throttle opens and the boost is being delivered by the supercharger.

The reaction and feel are almost instant, you get to instantly feel the difference and rush of the torque.

4. Makes Less Noise

Compared to the blower, the Whipple supercharger makes less noise. Blower also known as a centrifugal fan or Blow Fan is responsible for the movement of air in a direction and angle that’s perfect for the fluid flowing in.

5. Requires Little or No Maintenance

Once the Whipple supercharger has been installed, little or no maintenance is required. However, this is dependent on if the supercharger is well installed.

A wrong connection during installation will most likely cause you not to feel the expected outcome and may lead to the need to constantly check the charger.

6. More Efficient and Effective than Root Type

Although both Whipple and root-type are types of superchargers, the Whipple supercharger is more efficient.

Having a Whipple supercharger in a car is an assurance that there will be reduced parasitic loss, low consumption of power, and internal compression.

Not forgetting the modern design of the Whipple which makes them better for improving the car’s performance.

7. It Doesn’t have any Business with the Exhaust System

Whipple supercharger doesn’t influence the exhaust system in any way because it has no business with it. They work independently of each other.


Before installing a Whipple supercharger in your car, ensure it is one that’s a perfect fit. Whipple superchargers come in different sizes hence the need to get one that will fit your car in order to avoid problems. Also, if you do not have the know-how to install the supercharger, let an expert do it.
