Then again, I doubt GM is looking for maximum power with their supercharged 3800, but rather a nice safe power boost that can be cheaply recreated with a mass production engine without dipping into the mileage too much, it runs only about 8 psi. I believe. Boost past a certain point would be detrimental without charge cooling, and that would increase expense. GM also wants the pinache of being able to say a car is
Supercharged!
The conservative setup that GM uses on the 3800 makes for an inexpensive and attractive option, and it really does spice up the performance. There are also aftermarket pulleys available for this application to crank it up a bit more.
