How much horsepower does a 177 supercharger add?
Using the supplied 3-inch blower pulley and 6-inch crank pulley, the Weiand 177 supercharger produced a peak of 6.3 psi and increased the power output of the 350 to 405 hp and 446 lb-ft of torque.
How do I identify my Weiand blower?
On Weiand’s smaller blowers, the number represents the volume of air in cubic inches that the blowers move per revolution. For example, the144 series blower produces 144 ci of air per revolution. On the company’s larger 6-71 and 8-71 blowers, the number refers to the original GMC labeling scheme.
How do I know if my blower is 6 71?
In GMC diesel nomenclature, 6 represents the number of cylinders, while 71 represents the cubic-inch displacement per cylinder. So the displacement here is 426 cubic inches, and that is the approximate displacement of the blower as well.
How do I identify a blower?
1. Blower Identification Plate. When your blower originally shipped from the manufacturer it would have an identification plate with information about the unit.
How do I choose the right supercharger?
You need to know the make and model of your car, and the year, size and type of the engine. Superchargers are available for many different types of engines, and you will need this information to find the right types of superchargers or blower kits for your car.
How much boost can a 6-71 blower make?
Driven 11 percent under, the 6-71 produced a boost curve that began at 4.2 psi at 3,300 rpm and rose to 8.3 psi at 6,400 rpm. This pulley combination produced peak power numbers of 602 hp at 6,400 rpm and 551 lb-ft of torque at 4,700 rpm.
Why is it called a 6-71 blower?
Can a blower motor freeze?
Blower Motors can freeze.
Which type of supercharger is best?
Here a centrifugal supercharger is the winner, operating with superior efficiency over a positive displacement supercharger – particularly at higher boost levels. This means that for the same boost pressure the intake air will be cooler with a centrifugal supercharger and we can expect more power.
