Blowing tires off can be fun.
Really, there is just a massive difference in driving experience when you have that kind of power down low. The feel of the instant power is amazing. No, you can’t just mash the throttle from a dead stop on the street with street tires.
Your assessment is right on that both when tuned correctly are amazing. We have a bunch of back and forth on this forum where people have made the decision to go with one or the other and as a result they feel the need to argue and justify their decision. For most, they have never had the other option. That is why I am so confident in saying that you are right...they are both awesome. I have had both, running similar peak power.
The driving experience is much different. With the PD blower, power is there and is directly tied to the pedal smash factor. With the centri, it starts much closer to stock and builds power as the RPM climbs (like a turbo)...there is lag between the throttle hit and power delivery. I am not sure how else to describe it, with the Centri, I often thought I had traction, smashed it and had it break loose after the smash. With the PD, I smash it and if it’s going to break loose, it happens immediately.
Since you are an Na guy, I would say the Pd blower makes it feel like you have a much bigger Na engine...think smash 4cyl vs smash stock LT1. That doesn’t make one better than the other. . .just depends on your personal preference. As I said, my personal decision one way or the other would be determined by who you trust to do the work.
