If he's running 9lbs and making 527whp, thats approaching turbo efficiency on race gas. The Fast Intentions kit made 550whp at just under 10 lbs on I believe 100 octane. Every supercharger kit I know needed 11lbs or more to break 500whp.

The fact is that the 9lbs pulley actually can push more then 11lbs of boost as I noticed after installing mine. Average is 10-11lbs, its just 9lbs is the minimum.

Stillen supercharger kit- stock motor

What is the max boost, hp etc I should be looking at for my g.

I just put another stock engine with the supercharger because my last one blew up. (Connecting rod snapped)

I was running 9 pounds of boost and making 453 rwhp max with uprev tune on an engine with 60k miles. Supercharger only on car since 58,000 miles.
