All turbo manufacturers rate there turbos as crank HP. However some cars actually push the limits and make that to the wheels. There are a lot of variables that goes into that though. You are for sure out of turbo Xona turbos are similar to Garrett turbos looking at a compressor maps of any 61lb/min what you are making right now is way pass the efficiency range of any comparable turbo especially with the smaller turbine housing.

My Stage 2.5 turbo's are now called the Stage 2 turbo's.

What get's me is Moses's car (aka Carbon Z) with the larger stage 3 turbo's and a 4.0 stroker motor only made a little bit more whp than me. Explain that one.

Who's knows is there even a dyno graph of this car ? I wonder how many pounds of boost so variables not enough data to go off of.
