ok 2327lbs (I added your 200lbs of um gas? haha)
say I had no mods at all and stock 160hp.
by the calculated 1/4 website I'll still run a 14.9
I imagin an exhaust, header, hyper ground system and the new crank pulley will add hmm 20hp? (low but your a dick if I go realistic) so we'll say 20hp extra will be 180hp.. ok so if I ran 180hp to the flywheel weighing 2327lbs I'll be hitting a 14.4 1/4 time. I didn't guess this either I took everything I said straight from your weight added and the calculated 1/4 time site. you can do the exact same and see for yourself. now... ***** about the facts
there's the site just so you know.
