hi i have a 1997 mustang gt. it is a five speed. with rebuilt trans 2000 miles ago. brand new borg warner clutch. with out anything except k n filter i ran a 15.13@91 but since then i put 2 chamber delta flow mufflers. flowtech off road x pipe with mil eliminators. underdrive pulleys. cold air intake. steeda triax short shifter and 3.73 gears. what do think i will be running now. since stock was 15.13@91 do u think i could hit 13's thanks ricky

You might be able to hit high 13's. You should be able to hit low 14's if you cant make high 13's.

do u think maybe if i got a 70mm throttle body and a ported and polished upper intake and 24# injectors i could hit a 13.5

Razor19

I've heard 75mm throttle bodies are better. I dont know if the bigger injectors are necessary yet. The port and polish would definetely help you out.

Bro., you are nowhere near 13's. I'll say mid 14's, but that's it. Here's why...
K&N: May give you 3 more horses. Good for .2sec off your time
Chambered mufflers: Good for 5-7hp
O/R x-pipe: about 10hp
CAI: worthless...should have been a M.A.F. Maybe 5 horses if ur lucky.
Tri-ax: great mod, good for making sure you don't miss 3rd. May can get a better time w/this if you screw up lot w/the stock shifter.
Underdrive Pulleys: 10-15...say 12hp to be safe. March Performance, & Steeda are the brands I say stick w/it for these.

These are mods will cut your time, but you're best mods IMO have been your gear, shifter, pulleys, & o/r x-pipe. You want 13's, get a m.a.m., straight through exhaust, 4.10's, DR's & then holla back!

you'll need a little more than that to hit 13.5. your best bet is a PI head swap. that's the best mod for stock 96-98 GT engines. with the mods you have done, you should be in the low 14's.

I agree with GSXR. Good explaination dude!

Also I read about using a 75mm TB earlier on your stang. For your year, I wouldn't do it because that will hurt you, not help. Stick to the 70mm. Port and polish...priceless.

quarterhorse

so u are saying dont get the injectors yet. but do get a port and polished upper intake. also get a 70 mm throttle body. but which mm mass air should i get.

quarterhorse

also i have been wondering. i know slicks are the best way to go but i still have stock axles so should i go with drag radial instead
