I have a 17% pulley for my SC.. im guessing thats roughly an added 17 hp to my 168 base...
would 187 hp make a huge difference in my cars performance? like 0-60 timings?

what would be the next cheapest high performance upgrade?- maybe a new crank?...

im also thinking of messing with my resonator... but does that actualy add to your cars performance?

 

i dont know about 17 HP from a 17% pulley, sounds kinda high. and yet a 17% pulley will yield a significant difference in 0-60 times ( being reasonable ), for the most performance for the least money id say lighten the vehicle up and get rid of those runflats. as far as creating HP upgrades mabe look into intake/exhaust/tune.

 

reomoving the resonator -- probably not. some have claimed 2-4 hp from the reduced back-pressure. . . but I'm not convinced.
Having said that, it is money well spent if for nothing else than the improved exhaust note
