Why did you choose a procharger over a Hell cat type supercharger? Is there an advantage of the turbos over the roots style blower?
While that question alone has been argued and contemplated for years and years as every power adder has advantages and disadvantages.
The Roots blowers are full power at low RPM and usually taper a bit on the top end. These give a huge low end torque advantage, while that sounds great in a drag race this can make traction very tricky, but if you are towing this is by far the best in terms of getting things moving.
Centrifugal are like turbos, but instead of using free exhaust power they use a belt off the motor. How is this better than a turbo you ask? Its predictable and instant. At any said RPM you can tune for any pedal position as it will be the same every time. Where a turbo may need to spool to get to the peak performance which can be wildly unpredictable. These superchargers are better for top end like a turbo they are more geared for high RPM boost, and less on the low end. This is better for traction and they generally hold full power all the way to the top of the power band. Great for drag racing and highway driving.
Turbos are great for racing and power combined but harder to setup. They can provide great midrange and top end power, but usually take some work to getting low end as they need exhaust power to spool and at low RPM's this is harder on some engines based on turbo size. They do run off exhaust power where superchargers need the motor to spin them up so in almost all cases the same level of boost yields more power. The major downside is predictability aka turbo lag. You cant just push the pedal down and power is ready to go, it needs to build. Ive seen cars do this very fast in a second or less, some are a few seconds. I know your thinking whats a few seconds? Well jump over a lane to pass someone real quick and you realize someone already had that idea and coming at you in a hurry, in that case 2 seconds becomes an eternity. The good news is when the power comes on its there for the ride! The other major drawback is the setup, there are frigin hoses everywhere!
Hope that helps a little. Its not the end all, but generally speaking.
