I can't speak about the Procharger but I have run blowers, nitrous and turbos on different toys and the turbos were the most impressive for ultimate power and reliability. I seen a guy at a huge car show in Mi. with a similar engine to your's in a prostreet S-10 pickup .
He had one big turbo on it and dynoed 1050 hp. He stomped a guy with a 6-71 blown big block Camaro.
