Well welcome to the forums
do you understand how turbos/supers work?
If you do it is easier to explain
but to make the most sense of this, you can only put as much compression into a cylinder as what the cylinder can handle
so for example if you are running 15 pounds of boost off a turbo, and your engine's compression ratio is 8-1 you are only going to fit 8 pounds of pressure per cylinder
its kind of like money, you can only use what you have
turbos are good for hi rpms
supers are good for the full band of acceleration
a risk is that if your bottom end isnt strong enough or built to handle what youre trying to do you are only going to blow the bottom end of the engine and it can be a costly repair
I have watched mustangs blow bottom ends out because they turboed an engine that wasn't capable of handling 28lbs of boost at 4600 rpm's
Believe me its funny when it isnt you and youre sitting in the corvette and a guy with a v6 mustang thinks he is going to beat you in a race, but when youre the guy in the mustang and you have a useless motor you can only be furious like he was
just food for thought!
my recommendation though, super charge it if you are sure your engine can handle it
i cannot tell you whether the engine can or cant but the supercharger is always packing boost
when you are at idle, you can be running 1lb of boost just sitting at a light and when you put the loud pedal down it only goes up in boost! my xr7 supercoupe is supered and it blows people away when i leave a light rollin the tires to pieces and ramming through gears (a mustang and a subie raced me, not a chance off the line, in the end the mustang ran me out)
