How fast roughly is a 2009 gt/cs with a tune, intake,373, x pipe, exhaust

and what would it take for my 87 gta, headers exhaust, shift kit ported runners right now I cant seem to touch my friends car and it just walks never tracked what do u think it would run

 

any ideas ?

 

2009 GT mustang? 4.6 mod motor? Ones i've seen run around low 13's with those mods depending on the air and drive.

My friends old 01 4.6 stang went 13.2's I think with all the bolt ons, well driven and cold winter air.

L98 GTA with full bolt ons should be a lower 13 second car in good air. Depends on the setup. If you went slicks/drag wheels, with 2800 stall or so, with a siamesed TPI runner with aftermarket base, 1.6 rockers, well tuned, full exhaust, it should run near 12.9-13.1's depending on the air. My full bolt on stealth ram L98 went 12.95 in november air but summer it would be 13.3's or so. Good match for stangs.

 

thanks man for the help looks like i still have some work to do... but yea that is the 4.6 with some minor mods though the 373 gears are when the beatings have seem to have gotten ugly lol appericate the suggestions on mods pz
