I just completed free ram air mod, descreened my maf, and as of now im looking at a potz ported tb. With those mods and lets a lid and cutout could i run a 13.0? The car is a 01 z28 a4 3.23 w/ aluminum driveshaft i guess its the fastest auto z28 gm offered with getting into the ss package. when my local track opens the car will have racestar 15x3.5 and 15x8 w/ 275/50r15 nitto drag radials i have left over from my lt1 car. The car is bone stock except for the free mods as of now.

 

Going on a complete guess I would say if you put it on a diet you might have a chance. Drop the seats and spare and you'll all ready have lighter wheels. A friends lid only 323 geared WS6 went 13.3 once. If it doesn't I wouldn't worry about it. Throw in a stall and you'll be more than there.

 

stock catback????? That will rob 1/2sec

 

I know several lid/exhaust birds that have gone 12.9

 

If you would have left the maf alone you would probably run faster.

 

I would love to see someone drop .5 with a catback.

 

^^this. I can see half a second from a full exhaust, but not just a cat back.

 

i knew they were bad but GEEZE lol

 

He has a cutout anyway so that catback doesn't matter. Assuming a good DA high 12s should be no problem especially if the car has been tuned for the cutout.

 

A great driver could hit 13.0's w/ those mods. I would throw a set of long tubes on and hit the track.

 

very feasible. not easy, but possible. i've seen many bone stock cars go 13.3-13.2 with nothing but drag radials in not so great weather.

 

With a lid, cutout, and a Diablo canned tune, my full weight 2002 SS went 13.42 @ 106-ish with a 2000' DA (it was about 85-ish degrees in Alabama that day). That was on crappy street tires cutting about a 2.1 60'...so with better tires and a really good DA, I'd say it is possible.

 

my 01 camaro when it had an auto stock 3.23 gears ran 13.0x with a lid bellow and a edelbrock cat back and no cats no free mods on street tires i believe with a set of radials it would have went 12.8

 

do you have to have a tune after getting a ported tb for a a4 car?

 

No
But a tune would get u mid 12s with ur mods

 

I say it BETTER RUN 13.0h or FASTER! I have lid and free mods only. my 8.37 should be 12.85-12.95@ 108
