Whatever man - Not attacking anyone, just telling the guy to look at what he wants to do with the car vs just listening to hype. Nothing I stated was in-accurate.

1 - Shipping weight on MY kit was 75lbs, Magnuson shipping weight is 125lbs. Not everything in the box goes on the car, but less parts that weigh less means it weighs less.

They must include a jack and the wrenches?

2 - the efficiency will all be determined with the speed in which the S/C is turning. The changes that Vortech has made to the Ti level products lets them move more air in the sweet spot of their efficiency curve, hence not needing to spin them as fast for the CFM required. My setup is moving almost 1100CFM at 6500RPM, but still under 10lbs of boost. My tuner has tuned hundreds of LT4 cars, but this was his first setup on a Vortech, said he was blown away with how much air it moved at such low RPM for a Centri setup

3 - I made a comment about how MY Camaro with MY S/C setup is - the torque comes on very hard at 3500, but casual driving it is hard to keep it in the power as you are always crossing just into boost and back out.

4 - I guess I have borderline stupid vision as I run every weekend on the street with WAY more power than I do and way better tires than I do but they still have to lay off so much so they don't haze the tires. I launch at 3300 on a 2-step and get consistent 3.2-3.4 0-60s. These are 1k HP cars and they all have to roll race as they can't do nothing from a dig (even with drag radials)

5 - Pilot Sport Cup 2s - he is the first one to tell you that 1st is really just the gear to get the car going and then get into 2nd to start making grip.

6 - not up to speed on all the Procharger stuff, but on MY setup, you can run any head unit from Vortec from the SCi (1050CFM) to the YSi(1800CFM) on the same bracket and intercooler setup (Vortec only has one I/C for the camaro, a big one).

As far as the pulleys go - with the design of the Vortec setup (uses a jack shaft vs a crank pulley setup like ProCharger) you have a lot more belt wrap, and according to Vortech / ECS, the stock width belt will work fine to 1000 wheel. They do have a 8-rib setup but they say you dont need it until 1200hp

Not all Centrifugal S/Cs are ProChargers, however their kits / technology are the most popular so that is the baseline that people compare to

2) A centri kit will not grow in efficiency to 8,000 rpm.... it will depend on the blower, inlet path, heads, cam profile, etc etc

3) Hard to keep on boost? Fundamentally you dont understand how the blowers work... centri builds to peak psi towards redline. Higher you spin (again based on variables) the more boost you will get....

4) Saying a PD blower is hard to drive and get traction is beyond ignorant. It’s borderline stupid. Look at graphs of the average 550-650whp P1X/Maggie/Whipple on an LT motor...they are very similar even torque curves. At a certain point they both will need stickier tires... as far as launching, again, at a certain point the Centri’s will need a converter to aid that....

5) Sounds like your friend needs better tires or driving lessons on how to launch a manual car on a non-prepped surface. Either way too many variables to use in an argument of power adders.

6) Your example of upgrading is confusing. Upgrading to a bigger blower also usually comes with the requirement of changing from a 6 rib to a 8 (preferably 10 rib if you are making real power on decent sized blower.) and upgrading cooling options. Also the bracketry is different depending on what kit you start with. Also to address your “one and done” comment about the PD blowers: the 2.3 Maggie, Whipple 2.9, Magnuson 2650, and Edelbrock 2650 have ALL hit 900+whp and the bigger units going easily over 1000+... so yes one and done but 90% of buyers won’t ever need/fund more than 800...

Ultimately each blower setup will need the same steps as you increase power: better belt wrap/grip options/better cooling/better supporting components to push more power. Look at your ultimate power goal and decide from there.
