1. The roots charger is all torque when you get in the boost (just search some dyne sheets) and most cars can not put that on the ground, instead they get a pile of wheel spin. I ended up peddling it just to get it moving. The instant torque feels awesome on the street, but makes going fast without spinning a science. I had a CTS-v at 814rwhp (Whipple conversion) that I can compare to my 6th gen now with much less rwhp.
2. The guys I see screaming for a T.C. are the roots guys, and I was one of them. My stock T.C. could not handle the torque in my CTS-V, my stock T.C. in my vette handled the vortex without any issues and posted fast track times than my V did with 100 less RWHP.
3. I have never had a pro charged car with any lag what so ever, you get instant boost as the pro charger is always "spooled up" so long as it's turning. It's nothing more than a bypass valve closing giving you instant boost. You should not try to slam other members and make accusations like they are internet queens and have no real world experience when your answer shows you clearly are one of those. There are a number of good examples on here I'm sure an experienced guy as yourself can find negating exactly what you are spitting out.
4. Out of all the options, I think they are all close/great options just different enough to sway someone based on what they are after manner wise, all of the options drive the same when the valve is closed, this about when you hit the gas and open that valve to actually allow boost to your car.. Each have their own mannerism to it.
The turbo set ups are the best IMO. They are faster and you can tune them to run what boost you want and set up a boost button to bring the power on as hard as you want. They seem to be the easiest on your motor and the most capable. This is an area I have the least experience with in gas cars though. Most of my turbo experience is in diesel trucks, diesels at work, and one G8 we boosted.

my comments throughout speak for themselves. I am not guessing. 2 Prochargers, 1 Vortech, 2 twin turbos (including my current daily driver), and 1 magnuson. I specifically called out the BS argument about traction and lag...
1.I assume that you realize the difference between roots and twin screw, even though you are using the term interchangeably?
2. Please check the fast list, twin screw guys are not adding a higher stall converter, but every centri blower on the fast list will, because it helps them jump into the peak power of the centri blower.
3. You can look at the power curves from any centri car, including your Procharger. If a pd blower has 100rwtq more torque from the jump, then someone who is used to the Pd, will perceive the build in boost as lag. It’s just how they work, a centri builds boost with rpm. A Pd blower runs full boost throughout.
- that being said, if you read the thread, you will also see that I called the lag argument BS because when you add a converter to the Centri, it jumps to a higher rpm range where the torque curve is higher...making the power instant.
Again, I was only playing with OP. I said the LT4 blower was an excellent choice...I also advised that all of the blowers were excellent choices and finding the tuner you want to use and following their recommendation was the way to go. So, thank you for calling me out, but next time, please read the thread before doing so, thanks.
