About 7psi of boost. Basically any entry level supercharger kit with the largest pulley they offer. My opinion would be to buy whatever supercharger you can get the best deal on and apply the savings to a full LT4 fuel system upgrade. That will give you a little breathing room instead of running right near the stock fuel system limits.
My car drives like stock and could be driven across the country...there is no compromise with the mods I have selected. I simply spent the money on fueling so I could run pump or E85. I only run about 8-9psi, but the E85 and extra timing makes a significant difference in power. My guess is probably 60-70whp over 91. I dyno'd 600whp in 5th gear on lower timing. 6th gear pull with 2-3 degrees more timing it should be mid 600's on E. No headers, just primary cat delete pipes. When the NPP valves are closed it sounds almost stock...total sleeper.
