    dude.......1 thing...dont campare your car to european or japanese cars...cause in all honesty......a german engineered engine will out perform a american engine if they are rated the same........................and did you JUST get your car or something? cause it seems like all you wanna do is race your car................................its a sunfire man.

    Weight does matter, but audi kid is right.. an ening that is a 2.2l made in america can not beat a 1.6l made in japan. Americans are narrow on the "pushrod" thinking. A 2.2l gm engine only makes 115hp at the crank, with no accesories on (including an alternator)... you will be looking to run high 17's in a stock sunfire, with a 2.2l and manual transmission

    I think what you want to know is this. On average for every 100lbs of weight it will effect the 1/4 mile times by about .1 of a second. So if your car weighed 3000lbs and you ran 17.00 then stripped 200lbs of weight out of it you *should* run about 16.8.
    You start with a bag full of luck and an empty bag of experience. The trick is to fill the bag of experience before you empty the bag of luck.

    If you take off 200lbs, you can lower 2.0 seconds on your 1/4 so you'll probably be hitting the 14's easily in your Sunfire. Those cars are really fast.

    Ya man, no problem. It's all about power to weight and those cars are damn light.

    You want power to weight ratio? Try taking an mx-3 that originally weights 2500lbs, now put a 2.5L v6 that's all cast aliminum and put it in the car ---> making it around 2350lbs

    Now take 2350lbs + 200hp +190lbs/torque in a fwd japanese car...

    btw: my engine arrived at the shop last week, we are just about to change the seals, gaskets, etc... can't weight until its in the car!

    weight and torque figures arent enough to make a call...

    u need to factor in a lot more things; and heres a few:

    the torque CURVE
    hp curve
    drivetrain losses
    gearing
    unsprung weight
    driver skill
    wheel size
    aerodynamics
    gasoline being used
    tires
    etc etc etc etc etc!!

    that is th ebiggest load of shit i have ever heard! you must be retarded! i sunfire ( 4 door?) even with 200 pounds shaved would still run slower than 17.0. go to the track and dont get you hopes up. your headed for low 18's high 17's ...
    me vs you: i know you didn't say you could run 14's gpomp is the dumbass giving you very false info.

    are you guys serious or joking? i read somewhere 100lbs=0.1sec so 200lbs would = 0.2 sec. don't know where you guys got 2 seconds from. a 100shot of nitrous probably doesn't even cut that much off.
