## How much more horsepower does a supercharger add?

Now, understand that 50 percent is a perfect-world scenario, and a supercharger does sap some efficiency from the car.

So, on average, a supercharger adds a horsepower boost of about 46 percent of the engine’s original specs..

## Is a supercharger worth the money?

A supercharger can consume as much as 20 percent of an engine’s total power output. But because a supercharger can generate as much as 46 percent additional horsepower, most think the trade-off is worth it. … Despite their disadvantages, superchargers are still the most cost-effective way to increase horsepower.

## How do I increase the boost on my supercharger?

The simplest way is to increase the speed at which the supercharger spins in relation to engine RPM. To do this either you swap out the lower “crank” pulley for a larger one, or swap out the upper pulley on the supercharger itself with a smaller one.

## What is a 6 71 supercharger?

For example, a 6–71 blower is designed to scavenge six cylinders of 71 cubic inches (1,163 cc) each and would be used on a two-stroke diesel of 426 cubic inches (6,981 cc), which is designated a 6–71; the blower takes this same designation.

## Why does a supercharger whine?

Centrifugal superchargers provide the most efficient air compression system, and they’re the ones typically found in most vehicles. The sounds that they make can turn heads on the busy street! When the compressed air leaves the discharge outlet, the supercharger creates a whistling, whining sound.

## How much boost can a 6 71 blower make?

Weiand Pro-Street 6-71 and 8-71 supercharger kits come with drive ratios that will typically produce 5 to 7 pounds of boost. These boost levels are based on 350 or 454 cid engines. The 10-71 through 14-71 supercharger kits come with drive ratios that will produce 5 to 8 pounds of boost.

## How much horsepower does a 871 blower add?

Similarly, it is asked, how much horsepower does a 871 blower add? Running less than seven psi, the roots blower upped the power ante of the 496 stroker by an amazing 238 hp and 185 lbs. ft. of torque.

## What does a blower do to an engine?

A Roots-type blower pulls in air and compresses it in the engine’s cylinders. The speed at which the supercharger fills the cylinders depends on how quickly it is driven by a pulley and drive belt.

## Is Twin Turbo better than supercharger?

A turbo is more efficient than a supercharger since your engine does not need to work harder to power the turbo. Because a turbo is not connected directly to the engine, it can spin much faster than a supercharger.

## Do superchargers shorten engine life?

Assuming a properly tuned system, proper oil change and engine maintenance, and similar driving, supercharging generally will not shorten the life of an engine, just as is the case with OEM turbocharging (with proper cooldown for turbochargers. …

## What are the signs of a bad blower motor?

Symptoms of a Bad or Failing Heater Blower MotorWeak airflow from the vents. One of the first symptoms of a potential problem with the vehicle’s heater blower motor is low airflow from the vents. … Fan only blows at certain speeds. Another symptom of a bad or failing heater blower motor is a motor that only functions at certain speeds. … No air from the vents.

## Can you put a blower on a stock engine?

Large blowers, like the 6/71, can push the same engine above 500ft-lb. … Because superchargers push the air/fuel mix into an engine, they’re well suited to stock motors — provided you don’t get greedy with how much boost you want to run or how hard you want to rev the engine.

## Do you need forged internals for a supercharger?

You DO NOT need to have forged internals to have a supercharger. Anyone who has blown up an engine after installing a supercharger with less than 14 psi has done it because of one or both of only two reasons; 1) a tune that runs too lean or that disables or desensitises the knock sensors, or 2) excessive RPMs.

## How much HP does a Whipple add?

The industry leading Whipple Shelby GT350 system makes up to 875 (+350hp) engine horsepower and 660 (+231ft/lb) foot pound of torque on 93 octane fuel with only 9psi of boost!

## Is supercharger better than Turbo?

Which Is Better: Turbo- or Supercharger? Each can be used to increase power, fuel economy, or both, and each has pros and cons. … But superchargers can provide their boost almost instantly, whereas turbochargers typically suffer some response lag while the exhaust pressure required to spin the turbine builds.
