depends if you have drag radials ?
maybe 12.8

Justin_2000z28

Nope no drag radials, I don't want to brake my dd , but I'll run either 18in z06s with street tires, or 17in n555rs

Well the 555R's are a drag radial technically. Ever ran at the track before?

Justin_2000z28

Yeah it ran a 14.7 with the tb only opening 3/4 of the way. and 2.73s with z06s. Was not a good night... Lol

Yeah i'd say realistically high 12's considering everything mentioned here

get a stall and say hello to low 12s. 12.6-13 as you sit now is my guess

Big gears for a near stock A4. Get some long tubes and a stall in that thing. I would say 12.75 if she hooks.

Justin_2000z28

Yep but I'm running it tonight I hope it does good!

How did she do.

MikeWS6

Im going to say its around 320rwhp because the auto with 4.10s are going to eat some power. 12.9's should be good with those mods.

Justin_2000z28

Horrible , 14.4 @97mph had her dynoed Saturday , made 240 hp, 290 torque

cbr600rx7

iTrader: (12)

Wow. Any idea whats going on. Should have made at least 310 on a dyno jet or 285 on a mustang dyno and that's on the low side.

something is deff wrong with that car. those power numbers are way low

Other than you being an A4 with gears, we're pretty similar but you should technically be breathing better with the LS6 intake and ORY/gutted cats, so I'd hope you would run around what I ran. See my sig. Something is terribly off with that car though. Almost 200k on the clock, maybe it just needs a good freshening? Has a tuner looked at it yet? You're in stock LT1 category :-/

I mad 307/322 with a Lid, tune and cutout so start checking, something isn't right. The 4.10's will not eat that much horsepower. Is it throwing any codes, and where did you dyno it at?

Justin_2000z28

I dynoed it at vengeance racing, it's throwing codes, but just air egr
And rear o2s cause of the cat, and one other one I forget what it was about
That's what I was shooting for the guys at vengeance said my car should have made 310hp
I called spartan lsx and told him what my car is doing , the trans has been acting up and has been slipping, he thinks that that would have caused low #s due to the strain on it. And my car is un tuned at the moment but I don't think it will make a big difference. But I just got a beater for graduation so now I can start making drastic changes to it.
