seems a tad slow for 240kw in a corolla - need to remove those subs and i reckon easy 12s :) Actually for a FWD car, this is quite impressive. Maybe we can get a group buy on TRD Superchargers for 1zz's :D Actually, If you read the 9th gen forums you'll find that adding a TRd supercharger along with a heavy list of other mods, you'll be running between 14.6 and 15 quarter miles. so basically its like adding lift that the stivo already has. Although i'd love ot have one on my 1ZZ just so i can keep up with Bill :P
