Bolt ons with a2a supercharger kit

Think of it this way. You take a large turbo and put it on a 6.2L V8. You are going to make 800whp at 10psi. Take that same turbo and put it on a 2.0L and you will make 400whp at 30psi. There is literally just less boost being consumed by the engine since it cant move enough air in and out fast enough, but the boost numbers are still much higher.

Now as far as pushing up the boost vs bolt-ons, would it more make sense to push up the boost and bleed off the excess if we wanted to emphasize lets say mid-range power vs say using bolt-ons that emphasize the midrange if we aren't exactly looking for peak numbers?

I mean when your sitting at 500whp in the midrange and pick up 5whp with plenum work are you going to notice a change in the car at 505whp?

Honestly I dont have the numbers for this but am guessing for the time and money it may not be worth it. But if your looking to squeeze every last drip of power from this thing in the mid range and money is not an input then I guess its worth it.
