I've set up both for drag cars and I'll tell you this:
The turbo is A LOT easier to control at launch.
The Procharger creates boost instantly which (at least on the engines I have done) blows off the tires or causes wheelies you don't want to do. With a turbo you can launch easy, hook up, and then the boost comes in for the rest of the race. Can be the difference between life and the alternative.

On the street the Procharger is more fun for the same reasons...





I have to disagree with this. a properly set up procharged car will go right down the track without any help. I do it regulary and i'm on true 10.5's

A procharged car can leave off idle, a turbo can't

No need for a boost controller with the procharger as the boost is directly associated with RPM

i have more but lets let the turbo guys come up with their pros




Our 135 Procharger ran a best speed of 210 at 45 pounds of boost. Our twin turbo car with the exact same engine has gone 225.50 with 44 pounds of boost weighing 200 pounds more. Guess which makes the most power?




You didn't list the ET, so i'm going to guess the procharger ET'd better. Plus what was the comparative size of the twin turbo's inlets versus the single procharger?
