Yea not even close man....turbos take a LOT of power to drive, just slightly less than a procharger.
Just for comparisons sake, the inducer on an F2 is 114mm and exducer is 171mm. A PT114 turbo has a 114mm inducer with a 141mm exducer. Dont know what the max speed is on the turbo, but I bet its pretty close to the F2.
They are essentially the same thing, centrifugal compressors. The procharger is driven off a belt from the crank, the turbo from an air turbine in the exhaust.

Maybe another thread would be a place to get a bit deeper into this but procharger requires power to make power, turbo takes very little event at extream hp levels.
So at the same PSI you should net less hp correct? Only a dyno will give us the final answer, and the track will let us know who can run fastest on any given psi.
This is a killer truck and I am not taking away from it but I don't see a logical explanation how it could be better then a massive turbo on the same long block. I would think a properly set up turbo will make similar or more boost at the line and should spool as fast as the charger or faster. Things don't always work out in the real world like they do on paper.

Would I be quicker with a turbo.........probably not.......I don't know how they work and my eyes are round. I'd probably screw it all up.

Turbos spin a lot faster than centri blowers. And you could never really dyno test them for comparison, as there are other variables you'd have to change to optimize output from each forced air application... For a turbo to really shine above a procharger, the turbine has to get pretty huge. High backpressure (faster spooling) turbo applications can certainly rob a significant amount of power though.

F2 has max speed of 65,000rpm. Not that thats the choke rpm, its probably the limit of a good efficiency zone. True max rpm where you get compressor choke and/or rub on the housing is probably 70-75k. A turbo compressor of the same size will have the same limits for the same reasons, because like I said, on the cold size, they are the same thing.
