Comparing N02 to PSI

[Mach 1]

...theres quite a few variables to consider here. Blowers, turbos, etc...dont produce the same horsepower increase on different engines. A 15 psi blower will roughly double the horsepower of the engine its on. If its on a 200 horse N/A 302, and tuned properly, you should make around 400 horses. A 15 psi blower on a naturally aspirated 90 horsepower chevy cavalier will make around 180 horsepower. In one case, the blower makes 200 horses, in the other, 90 horses, both with 15 psi. Are you starting to get the idea....
