I DD my car to work and low to mid range power and torque is a main target (After all that's why I chose screw-type superchargers instead of Turbos) to have as much as possible low to Med range Torque and Power.

1st thing to say is any power over 280Bhp is playing with fire on stock internals
some folks get away with it but its a lottery as to whether your particular set of rods will go pop or not

so yes if you want 330 bhp / 300whp then it best to replace the airbox with a larger filter element part
if you can find a larger diameter or more free flowing throttle thats not very overpriced ( cheapest I've seen is $1000.....) then go for it as it will pay dividends

and yes a 1320 will come on boost earlier than a 900 unit, its bigger
but the 900 can be spun faster to compensate
