i ran 15.5 w/a slightly modded 92 xsi b16, and itr’s can’t even hit 14’s up here (usually around 15.1-15.4’s) so i think elevation has a lot to do w/things
not too bad for the first time at the track but i think you can still do better. i had a 92 gsr with a b18a (blew the b17) w/ a short geared ys1, short ram intake, crappy 2.25 crush bent exhuast, no ps, no ac, back half gutted ran 15.4 @ 86 on all season yoko yk420s. work on that 60ft and try using OEM ngk spark plugs & wires and im sure you can cut a low 15 or maybe a high 14
whos the guy next to u and where can i get an intake extension like that?
K&N Makes a “filtercharger” intake. i have one, it connects to the stock rubb piece, and is made of course plastic on the inside so u get lots of differnt frequency’s of air through the intake. comes with a K&N lifetime Cone filter, and Velocity Adapter as well as a Metal bracket bar to stablize the cone head. It screws into where the stock air box bottom is screwed down if that makes any sense. i have pics if u want to take a look
