Actually the turbo only car has a better curve power band. If we look at the dyno graph and look at the points from 110mph – 135mph that represents about a 1500-2000 rpm range (depending on if it’s a stock ring and pinion, tire size etc). Now that is a good indication of real usable racing power. The rpm drop on the t56 if shifting at 6500rpm is 1st to 2nd has a 2150 rpm drop (what that means is when you shift from fist to second your rpm will drop down to 4350 rpm) 2nd to 3rd is 1750rpm drop 3rd to 4th 1500 rpm drop.
So you can see that 1500-2000 rpm range is very important because that is where the engine is going to be performing in a race.
So looking at the T/SC combo we have 110 mph =890hp, 115mph= 1050hp, 120mph=1188hp, 125mph= 1140hp, 130mph= 1090hp, 135mph=1000hp,
The average power =1059hp
Looking at the Turbo only car we have 110mph=930hp, 115mph=1050hp, 120mph=1120hp, 125mph=1150hp, 130mph=1150hp, 135=1171hp.
The average power for the Turbo car is =1095

Where's your beef? Now you want to compare power with equal PSI? That's not the point, never has been. That's just like the ricers arguement well if I had 8 cylinders...

That is a weak argument, for a ricer to get 8 cylinders, would take a engine swap, to turn up the boost on the turbos is a turn of a knob, not even close to compare the 2.
The bottom line is that 1188hp is impressive until you take it into context. Look if you added the twin turbo system you can keep the SC on and make your 1188hp @44 psi, or you could remove the sc and run the turbos up to your 44 psi and make close to 2000hp, or drop the psi down to around 30 and make over 1200hp. Remember the more you compress air the hotter it gets, with increases the chance of detonation. So why not remove a heavy supercharger to increase your power?
