71 Dart / 5.9 Magnum / Procharger

I'm running 10 lbs of boost. Using the Wallace racing calculators I've added approximately 100 horse to the crank. Was hoping for an addition of 200 horse at the crank with 10 lbs. Again, hoping the exhaust might make a big difference.
The centrifugal chargers tend to take a percentage of HP but a 100 horse power is a pretty good gain.
