ok, please keep in mind i DID put this in the n00b section LOL

i have 2000 Z28 auto. assuming decent tires and a good hook day at the track

once i have a cat-back SLP loud mouth (still with cats)
and the slp lid kit. how would my car fair at the drag strip?

 

Depends on the track, conditions, altitude, how well your car is running, gears and your ability to drive.

All that aside the biggest variance will be gears, the regular 2.73:1 geared car will not be quite as quick as the optional 3.23:1 geared car.

13.6 - 13.9 @ 102-104mph would be a fairly attainable estimate but considering all the above variables you could go quicker or slower.

Bench racing and magazines have piloted a manual LS1 Fbody to low 13's several times and there are even a few in the high 12's trapping 108mph, but these are more the rarity than the norm and are more likely to be a lightweight optioned z/28 rather than a fully loaded one.

 

That article brought a smile to my face

 

hahaha me 2

and to answer the question. you will probably run 13.3-13.9

 

I have a 00 WS6 A4 with a lid and a LM1 catback......see my sig. for my 1/4 mile time. 75 degrees, 50% humidity and a 15 MPH head wind.

 

kid i know near by has a 2000 z28 a4, only mod is an ls6 intake, factory everything with
2.73's and street tires, ran a 12.9

 

13.48 @ 104.87 is what I ran with a lid and a catback, with 2.73s

 

like said above all depends on the tyrack and conditions....if you are close to seda level and can pull off a 2.1 60ft or better mid to low 13s...

for example our track here is slow ls1s run low 14s high 13s stock....summer d/a is usually
3500to5000+
oh and congrats on the purchase...

 

Nice!!!

 

I did alright...

I have also seen a couple Auto cars claiming high 12s and numberous auto cars pulling low 13s bone stock so if you race in the right conditions (DA of 0 or better at a low elevation track) you could crack a 12 or low 13 (low 13 with ease)....

 

alot of it depends on the driver too

 

There are a million variables, but chances are on average you'll see a 13.3-13.6 at 104-106 with the catback and lid, being an auto.

Of course, it's very possible you may run a bit faster or slower, especially if you've got some drag radials, but those are what I've seen on average.

My buddy's 2000 Z28 M6 with a catback and lid did a best of 13.3 at 106 on a rental day at a mediocre track and he's a good driver. That was also the best of the day and his range was 13.3-13.5 at 104-106.

PS - that is one sexy car you have there.

 

Not in an automatic, the driver doesn't matter, all you have to do is push the gas peddel down lol...... as long as your not overweight running with a full gas tank you should hit low 13s

 

Getting in the pewter line...

O and I'm with everyone else here, mid 13s. Unless you're at 5800ft like me then low 14s.

 

Wow, that sucks...

I couldn't live there just for that reason.

 

Yea I just moved here a couple of months ago. I had to mod just to get back to where I was before lol.

 

My car stock with that exact same setup (SLP Loudmouth Catback and SLP Lid/Ram Air Kit) went 13.28 @ 107 mph with a 2.0 60' thanks to the 2.73 gears.

 

d/a at bristol is normally that high in the summer and the track has an incline...took alot of power to get 11s...

 

You should be in the 13's period depending on altitude.

I did a 13.7 at 107 with 2.3 60' on my bone stock '00 z28 m6, who knows what would have happened with some traction (other than blowing the rear end).

Good luck, your in for a great ride nonetheless.

 

Trust me, a bad driver can slow down an auto.
