sounds just like mine was. i thought i was gonna get creamed by cars after i pulled out. one time actually pulled back off road to let cars by because the thing wouldnt hardly move. i love my sport and i'll drive one till i die. but it is the most underpowered vehicle i have ever drove. the stock fan comes on automaticly under a certain rpm,with the ac on the compressor starts sucking horespower. between that fan and that compressor theres just nothing left for your foot. when im approaching long inclines on highway with air on,i turn off the green lighted button on dash which turns off ac, and can feel the extra power. sad thing is its still not enough to keep from having to floor it to get up the stinking hill. so i just drive my sport like i stole it. i haul an atv on a trailer.pack the car with gear. and it gets me where im going and gas milage isnt too bad. you just gotta get used to reving the engine to 5000-6000 rpm to get over any hills.

now...the primary prob. getting off the line quicker. put on electric fan.remove old pulley ,get shorter belt or you wont get the best results. turn ac off. and there you have it. thats as good as it gets. i wish we could get a stall speed for the autos.
