I would start with your basic bolt on's(Lid,headers,Exhasut,ETC....) and then get gears that's a big one ohh yeah don't forget about stcikey (NITTO"S 555).Anyways after you get all that on you will need a rear end rebuild or a new one! Go with a 12 bolt if you are A4 but if you are M6 go with the 9in if it don't bug you toooo much. but that should give you some good times........

 

I'm an M6 with a Lid, Long tubes, ORY, magnaflow and 80mm tb I ran 12.8 at 113 with a 2.2 60ft. I just got the car tuned and it feels much stronger, I am puttin on drag radials and going for a low 12.

 

one of my buddies had an all stock 98 ws6 a4 like mine, he put some welds on it and some sticky tires and it ran 13 flat to 13.1 all day long. i seen this with my own eyes. not saying mine will do it but thats just what i saw....

 

My 01 WS6 with just a K&N filter went 13.3. With some type of drag wheel it might have went 13.1. So what you saw might have been possible if it were a newer WS6.

Mine went 12.9 with a lid, catback, ram air kit and tune. Now I'm running 11.8 with a ported TB, electric water pump, skinnies and a stall. Headers will likely make your ETs worse without a stall.

A good stall and some tires will help you most of all in the 1/4. If you are concerned with track times I recommend saving any money you were going to spend on lid, exhaust, TB, etc... and just buying a good stall.

 

I ran 13.49@107.8 with a cat-back and lid only. Got headers and ORY now, and will have 315's by spring. Hoping to hit high 12's.
So basically id say somewhere in the mid-high 12's with the mods u listed.

 

Bone stock I ran a 13.21, with just a lid 13.01 and with a lid and catabck 12.97. It takes some good air and you have to be able to hook, but you can get in the 12s with minimal mods.

 

i have some kooks headers with true duals on the way, how much hp at the rear wheels will that bump me up to? thanks for the comments guys this is the second ls1 car i owned but the first one i decided to put mods on. there are several mustangs "**** stangs" which i call them running around where i live. i've done alot of street racing with my other cars but they always bitch about me beating them cause they say my cars are all out drag cars, so i bought this ws6 to build up and and whoop some *** this way. any tips and hint are helpful.... thanks

 

all i have is a 8.68 in the 1/8th when my car was stock.. havent ran it with the mods, my car gets a lot of street action! hopefully ill get it on the track more this coming season.

 

Back about 6 Years ago my 1998Z went the times in my Sig, shows you that some of them are just freaks.

 

I'd say with the mods you have listed you will be very low 13's on street tires. Maybe even high 12's depending on if you have 3.23's instead of 2.73's.

 

my car has 3:42's
