Regal on the Prowl

They are! (and we're not even modded). The levels of boost you can get out of them are unreal.
I don't know of any other L67-powered car that'* lighter and smaller from the factory.

For some reason, the whine is not very pronounced in our GS. You can barely hear it...even when I maxed it out one time at 9.8 lbs.

None. Bone stock. It'* how we roll in all our cars.
I wasn't too clear when I made my initial comment.. On a stock H-body, the whine is much more pronounced. Maybe it'* just due to cabin insulation differences.

Maybe I'm being stupid here - How can you make more boost on a certain car with the same motor as another? Is it just because it'* lighter, RPMs pick up faster?

IMO, Regals tend to make more boost because there is more restriction in the exhaust because it has the u-bend. If you removed the u-bend, you would probably see the same boost that a stock Bonneville L67 has: 6-7 psi. It has nothing to do with the weight of the car.

More boost is bad since that'* the pressure not doing much, right? If you were to start porting and polishing, you'd justifiably lose some boost. That is good, though. It'* all the more air actually moving through the engine.
So, is there also more boost on other W-bodies like aftermarket-supercharged Impala and Grand Prix cars?
