good solid 15.20's. Take it to the track and find out.

If you have never been to the track before, don't expect good times but if your an A4 it isn't that hard. My guess is around 13.4-13.5 with a 2.2 60ft.

Good luck!

My buddy has nearly identical set up to you.
00 z28 with Loumouth cat back, and a lid. He has 275 wide tires tho.
He also took out about 100 lbs of weight last time at the track. He ran 13.5's all night long. His best is a 13.3. I wouldnt expect much better.

Sounds about right, i've been to the drags and seen quite a few fbods. i'm looking to get in the mid 12's without heads/cam.

i'm sure i could hit high 12's right now just with some street radials. it's mainly a daily driver so a stall might be a little too much.. but thanks for the suggestion

depends also on your elevation and humidity . . . i got a 13.2 with lt's, full exhaust full intake on street tires and a a shitty 60' time so i'm thinking 13.4 or 13.5 for you and a stall will help you

stall it and you can expect those times mid 12's

what rpm stall would i want if i got one? i would want to launch any higher than 2500 would i? don't wanna break the rear end.

i wouldn't want to launch any higher than 2500(my mistake)

LS1 Terror

i would launch like at 1200 dont wana break the rear end

jam01

i have an 2002 ss 6 speed, i was running 13.3 108mph. no modiications done at the time i had just about no traction off the line i was launching about 3000. rpm. start with a set of drag radials yes a converter will def help i wouldnt go higher than a 2500 stll for street use. if you do get a good trans cooler. and start saving for a rear now these arent the strongest, altho it could last but just in case.

If a stall makes the street driving that much worse then why does everyone say get a stall and it will be more fun than driving a stick???

don't waste your money with a 2500 stall you're only going to want to go bigger latter, get a Yank 3600 SS.

i can see a 13.1 if you hook. otherwise probably 13.3-13.5 or so.

also the rearend will be fine if you don't let it wheelhop. i pulled MANY MANY 1.6x 60' on the stock rear with 373s and a dif cover. car had 45k on it when i bought it and i think 63k on it when i sold it. the last 15k miles weren't what you'd call easy haha.
