Written By: Andrew Cilio. Anyone who gives you the line "there's no replacement for displacement" when asking about a supercharger has probably never driven a boosted Mustang before. Neck-snapping power and the feeling of control over the road are only two of the many awesome byproducts of installing a blower on your Mustang.

This amount of power is what places superchargers at the top of the wish lists of many enthusiasts. The centrifugal supercharger became a very popular option for the Fox-Body Mustang , although its first use on the Mustang date back several decades ago. Carroll Shelby starting using Paxton superchargers on certain Shelby Mustangs back in the sixties. These particular Shelbys command a very high price tag among car collectors today.

The centrifugal supercharger is best suited for producing higher RPM horsepower, as it generally starts providing noticeable boost around 3, RPM. This made the centrifugal supercharger ideal for the 5. The centrifugal supercharger is placed beside or in front of the engine, with air entering the front of the supercharger.

This pulley spins the impeller, which is found inside the supercharger. The impeller looks like a series of blades, and can be seen through the air inlet. As the impeller is spun increasingly faster, the motor's RPM increases as well, and the impeller produces enough force to overcome the vacuum that normally pulls air into the motor. The supercharger then forces air into the motor. Boost is represented in psi pounds per square inch. Typical boost is in the psi range, although highly modified engines can see boost much higher than this typical range.

The biggest advantage of the centrifugal supercharger is fitment. It mounts to the front of the engine much like an accessory would. They generally use an air- to- air intercooler. The compressed air is pumped through the intercooler before it enters the intake plenum. The intercooler mounts to the front of the engine bay and is also similar to a radiator just like the air-to-water intercooler. A centrifugal supercharger spins at very high speeds, thus, creating heat. To combat this, oil is required to lubricate it.

The official correct way to change supercharger oil is to remove the blower from the engine. Then, remove the plug, and drain the oil. This can sometimes, depending on the model, need the supercharger to be tilted a certain way for a long period of time. This is to let all the oil drain out.

Once completely drained, fill with the correct specification. The two most commonly used centrifugal superchargers are Paxton and Vortech, although there are still many other manufacturers to choose from.

It should also be noted that a centrifugal supercharger and a turbo share the same basic operational concept. Positive displacement superchargers are easily recognized as they sit directly on top of the motor. There are some exotic cars, however, that use a positive displacement charger mounted on the side of the engine. With a positive displacement supercharger, air enters it, and ends up at the rotors. From there, the rotors whether twin-screw or the rounded Roots-style compress the air as they spin inside the supercharger.

From there, it enters directly into the intake of the engine. Roots style blowers offer excellent torque at a blip of the throttle and provide boost all through the rpm band. Ford uses them as their stock option supercharger for their durability and consistency. The twin-screw style superchargers perform similarly, but twin-screws have tighter tolerances than the roots.

While great for high boost applications, the tighter tolerances means more heat produced by compressing incoming air. Needless to say, excessive heat can hamper performance and require increased cooling, so there's a tradeoff. Depending upon the exact type of positive displacement supercharger, there may be more than two rotors used. With the modern positive displacement superchargers used on Mustangs, twin rotors are normally employed.

Just as with the centrifugal supercharger, the rotors spin at high speeds and lubrication is required inside the supercharger. Positive displacement nearly always use a self-contained oil system, which will requires oil changes on a regular basis.

If throttle input is decreased, the boost pressure must be relieved. Sometimes with smaller boost installations of 5 psi, a blow-off valve may not be used. As boost pressure increases, however, the ability to relieve the boost pressure becomes increasingly important, as engine damage could result.

This equalizes the pressure on both side of the rotors and increases the efficiently of the supercharger when boost is not required. This comes into play at cruising speeds or slow acceleration; basically, times when very little throttle is being used. Heat lessens the density of the air, and can potentially increase the heat in the engine.

The intercooler is typically placed after the supercharger, and the compressed air is forced through it. Intercoolers are fed by engine coolant most of the time, although some race setups have the ability to facilitate the use of ice. While the air passing through the intercooler will cause some minor loss of boost pressure, the benefits of cooling the incoming air far outweigh the disadvantages of an intercooler.

A centrifugal supercharger uses an intercooler that is placed into the piping that connects the supercharger to the intake. In the case of a positive displacement supercharger, the intercooler is placed between the supercharger and the motor.

The air exits the underside of the top mount supercharger, is moved through the intercooler, and then into the intake. While the use of a bypass valve has helped with this aspect, there is still a small impact to fuel economy. A supercharger has several advantages in its favor, however. The first of these is the fact that, unlike with nitrous, bottle refills are not necessary. The power provided by a supercharger is also always ready, requiring nothing more that the throttle to be opened up.

Because of this, and the fact that the use of nitrous on the street may be illegal on some areas, supercharging is one of the most popular options for street-driven Mustangs. With an increased amount of air pushed into the engine, fuel delivery must also be increased.

This can be accomplished through a higher volume fuel pump, or a pressure booster like the Kenne Bell boost-a-pump. Larger fuel injectors may also be needed depending on the application.

Both supercharger types are belt driven, meaning they operate off a pulley. The pulley usually spins faster than the engine, but is directly proportional to engine speed. The size of the pulley dictates the boost levels.

Many aftermarket companies such as Metco offer different sized pulleys to attain different boost levels. Since the Cobra Mustang came stock with a supercharger, a popular modification is swapping out the pulley on the nose of the supercharger. Like the underdrive pulleys mentioned above, this changes the ratio the crankshaft spins the supercharger.

Some manufacturers claim changing the pulley can net you 50 HP! However there's one big hang-up: the serpentine belt. What size do you get? Below is a handy chart for the Mustang's. For each crankshaft pulley and supercharger pulley combination we've listed the appropriate serpentine belt size. As with any engine modification, the need for a tune cannot be stressed enough.

A good tune will not only keep the engine operating safely, but will also take full advantage of all the available horsepower. The tuner will be able to set timing and fuel parameters to get most out of the boost, without having the engine go poof.

If high levels of boost are the goal, be prepared to install a forged rotating assembly in the block. The more boost, the more power. Not to mention some pretty extreme pressures on the engine internals. The stock rotating assemble can generally handle about 8psi with a good tune. That is enough boost to really throw you back in your seat.

Get a bigger blower, of course. The Kenne Bell upgrade Kit simply offers more HP and boost potential, with plenty of room to grow, without expensive bolt ons. The blower dyno allows Kenne Bell to regulate all of the variables to properly evaluate the supercharger, namely blower speed, air temperature and pressure into and out of the blower, and the parasitic losses associated with driving the blower. Subscribe to a Magazine. Adiabatic efficiency on the inlet side is the next step in the equation. The same was true with the engine coolant temperature; the idea being to hold all possible variables constant so only the power or supercharger would change. More details on the 3.

Ford Mustang Supercharger Tech Guide

That segment just whet the appetite of our power-hungry readers. Today, that craving can be satisfied. We discuss some of the features and benefits of this style of positive displacement blower, as well as the pros and cons, research, design and development. Positive Displacement. Twin-Screw Supercharger Benefits. This pressure increases as the air flows through the supercharger is described as its pressure ratio. Whipple has its own in-house CNC shop where everything from twin screw rotors, to billet inlets and even billet rotor housings are machined in this facility.

Streetable Benefits. Not everyone has a full-tilt racecar, and some of us even drive our hot rods on the street. For those reasons, we inquired with Dustin about the maintenance involved in a twin-screw application. Other than that, we recommend changing the belt every 20, miles. In terms of general maintenance on a street application, everything is pretty much the same as stock.

Enthusiasts who may not have access to a boost gauge right away are unaware of this; but the daily driving fun factor is greatly increased with the positive displacement for this reason. Not all Whipple units look the same, either. Engineered Intercooling.

Whipple pays a lot of time and attention to the flow of air above the intercooler. After that, Whipple determines the actual size of the intercooler. With the front feed inlet, we were able to design a more efficient manifold as well as the plenums above and below the intercooler. Compressor Sizing. The rotors are inspected before and after machining, as well as after coating in batches. With in-house manufacturing, we are able to develop new technology at a much faster rate.

We currently have two new generations coming, and many different sizes. The new rotor development is also for private label and applicable to OEM applications, something will be seen in the very near future. Whipple continues its quest for the highest flow possible by maximizing the most power available on pump gas first, and that starts with the correct sizing of the inlet and screw compressors.

For example, if you only want to make horsepower today, you have the confidence of knowing these blowers are designed with a 1, horsepower inlet system in mind, built right into the whole package. We try to maximize the flow by matching the inlet size directly to the compressor size that we incorporate into that system. If you oversize a supercharger, you may sacrifice some low end power. You may stay at the same horsepower or slightly less at the top of the RPM range. Adiabatic Efficiency Explained.

Terms like adiabatic efficiency AE and volumetric efficiency VE are thrown around a lot when discussing the different types of forced induction, but what exactly do they mean? VE is very critical on the airflow side. Adiabatic efficiency on the inlet side is the next step in the equation. Whipple spends countless hours on a supercharger stand measuring everything from IATs, VE and AE to determine the correct size of the components used to create one of its supercharger packages.

We spend a lot of time on VE to ensure that the compressor flows as much volume as possible. That in turn keeps the compressor speed down, lowers the power consumption and the intake air temperatures. The front feed system reduces losses by limiting the bends, kinks and pinches typically associated with rear feed types. Taking Your Temperature. Postitive Differences. Both of these supercharger versions are similar in appearance, and even construction — but that is where the similarities end, as Dustin told us.

With the roots not having internal pressure, the leakage is much greater, meaning its specific power is higher than a twin-screw. As Dustin reiterated to us, these kits are designed to each vehicle platform specifically, and are meant to grow with an increased power level as enthusiasts continue to modify their cars. Everything is virtually new with this kit, and almost nothing has carried over. Blue Oval enthusiasts keep an eye peeled in the near future for a tech article on a Whipple supercharger install.

Dustin also relayed that the third generation of superchargers is coming quickly. And finally, for Mopar enthusiasts, you can crank your Hellcat up to a massive 4. We will safeguard your e-mail and only send content you request.
