i had a 98 z28 a4 with lid, no cats, flowmaster muffler,nitto 555 and ran a 13.19@106.i see no problem for high 12's with your set up.

its possible, the springs might hold you back, but i ran 12.9 on street tires, the biggest factor most likely being the stall...

i ran 13.45 @103 2 wks ago < 98 ls1 a4 3.23 > just put in yank 3200 stall hope to hit 12s<12.6-12.7>other than that car is all stock <94000 miles>

i am having installed ls6 intake, jet hot lts and ory, took off all emissions and had it dyno tuned by fbody central. i was told to expect about a 12.80 what do you all think.

ya you should be doing real good i went 12.90 @107 with lid,cat delete,cutoff,shorty headers,on street tires...so you be able to do 12.60-12.80....

if stall was a 3400-3800 i think you would be there already

Like everyone else says more stall would help. You could always put a nice shot of nitrous on there.

i plan on installing a 3000 to 3200 stall. i want to keep the stall small because i drive the car everyday. it has to be streetable. i have not ran the car since it was nearly stock. i should get the car back tuesday evening. i plan on breaking the new parts in for a few miles and then going to the track friday. tthe guys at fbc told me to expect 12.70s. i cant wait to be in the 12 second club. i'll keep you all posted. Also if i did run 12.70s how much more could i expect with a 3000 stall.

The eibach spring would decrease his time????

yep^^^^lowering a car with stiff springsmakes it harder to hook....how is that converter???is it looser than stock anyat all....
I used that same converter in a 5liter fox i had once and it barely compensated for the cam i was using....on spray it worked well though....
In good air id say you will bust 12s wide open....

good luck....

got the car back today. it dynoed at 308hp and 318tq with a baseline with new parts installed before tune was 283hp at the wheels. not bad. the car feels like a hole new car. you can feel a huge difference mainly in the top end power. the car had a lot of dead spots now it is smooth throughout. once it hits mid 2nd gear and thru 3rd it is a rocket. i am very impressed and very satisfied. cant wait to go racin friday.
You can feel a difference in the converter over stock but not much. i put an order in for a 3200 stall.
