I'd say that you should be able to get a high 14 with a blower, you've gotta gain 1-2 seconds I guess, If you can get the traction it'd be a good start.

Hi.. the blower takes about as much power as when u stick ur air con on..all these ppl that say blowers take power to give power **** me..ULTIMATLY are gaining or loosing power? think about wat ur saying when u say, ur giving power to get power. Anyways, me and some mates were out and measure out the 1/4 mile on a cold nite... roughly... using stop watches i was constantly pulling low 14's that was spinning thru quit a bit of 1st gear. The reason turbos are progressing to be better and better is coz there are not alot of blowers out there that can spin 30,000 rpm++ .. a blower and only spin as fast as ur engine can turn it, with a turbo its different. I am selling my car..but if i was to keep it, keeping my setup the things id be doing to start breaking 13's and getting into the 12's would be incrasing the boost so i never get below 6 psi... understand with a supercharger, 6 psi... is 6 psi from the moment ur foot hits the floor... with a turbo u have lag but to compensate u get bigger boost.. so my goal with my setup would be to get a cam grind to work for top end speed.. and get the car dyno tuned witha new ems, bigger injecotrs... and shorter diff gears.. if my car did not pull a high low 13, or a high 12 id be suprised. this would be running no cooler, and only 6 - 10 psi. thats my opinions..... but im moving from the whole forced induction thing and going V8 for a while PS, buy my car Some original photos have not been recovered yet.
