idk where to post this but this but with 28x10.5 tires in rear changing form a 346 to a 456 gearing should increase 1/4 mile time buy how much on average saying make stock hp full weight car running 13.2-13.5 stock with perfect shifts?

 

In my A4,changing from 3.23s' to 4.56s' I gained .5 in ET(26" tires all runs).
Going to 28",I.m guessing a .4 gain changing your 3.42s' to 4.56s' and a heavier 12 bolt.
