i have a '99 z-28 (a4, 3.23) with the following power mods:

-all free mods
-slp lid, y-pipe and single side cat-back
-k&n air filter
-gms maf

what et/mph should i be running in the quarter mille at sea level? as long as the pavement and tires are warm, the car seems to hook up well, fwiw.

and what should i be running after the following mods that i will be adding at a later date?

-slp ls6 intake
-shorty headers
-thunder racing 220/220 .516 114 lsa camshaft

thanks!

Shorty headers?? WHY get long tubes, otherwise you will not see max hp gains from that cam.
APPROX!!!: los 13's with what you have now MAYBE high 12's
After APPROX!!!:Mid 12's
(guessing) Go to the track and find out Thats the fun part!

 

thanks...

i'm getting the shorties because they are CARB certified and thus will pass the visual part of a california smog inspection, and because of ground clearance issues- my y-pipe already drags when i pull the car into the garage. =\

 

Guy here runs 12.6 with just lid, catback and drag radials. Oh well another couple years and LS1 will be in my price range

That sounds really LOW with drag radials, slicks?? maybe.
but he didn't say anything about drag radials or slicks now did he.
