if the argument here is what can put power to the ground more efficiently i would go with a turbo...
yes you can have 1.3 psi at 1500 rpm with a supercharger... but you will only get your max psi at 6000rpm...
with my turbo setup... i'm putting 10psi (full spool) between 3000 and 3500... lets see a charger with a 10lb pulley do that...
in terms of stability... SC all the way... a constant build in power... a steady torque curve... make the engine feel like it was built that way... with the added whistle of coarse
more boost throughout rpm range = turbo = constant power to the ground
(it can really kick you in the ass if your not expecting it... try sitting in 3rd... then mashing the gas at about 4 grand... 10 psi puts you in your seat)
stability and a steady torque curve = super charger = max boost at max rpm range
(not a constant psi throughout most of the rpm range.)
just my thoughts...
and matty... you shouldn't be afraid of the dyno... (unless you think the SC will not prove itself to the turbo protege's) although so far it looks like it will

plus... a dyno and some good numbers will sell your kit... just saying its drivable isn't going to sell anything...
most of the people on this forum build their cars to toy around with... and make them faster... not more drivable (although both would be nice) lol
i know that if i'm gonna spend 3 grand on something... i want to make sure it does what i want...
COME ON MAN... MAKE AN AC RELOCATION BRAKET!!! that would make the car even more drivable... summers get humid man...
