I have a 96 camaro z28.
Its automatic has 88k on it.
I have a cold air intake and a slp loudmouth II.
Does anyone no about exactly what i would run with just those 2 things?

 

Depending on elevation and track prep probably flat 14 or just into high 13's. Upgrade suspension, drivetrain etc. and mid 13's should be attainable.

 

i think high 13s. i really depends on who is driving the car though. if you really need to know just take it to the track

 

i am in the spring time.
i just wanted to no cause theres alot of hondas in my town who think they have 12 second cars when i beat them...

 

It will depend on which rear axle ratio you have. If you have the 2.73 rear axle (base ratio), its not going to be as fast as if you have the 3.23 "performance rear axle" ratio. You can tell by looking at the build code tag in the glove box - 2.73 is "GU2"; 3.23 is "GU5"

 

i have the gu5 3.23

 

Personally, based on the road tests I have from when these cars were new, they were not 13-second cars when stock. With a really good driver, and a really sticky set of tires, and a good launch, you might get into the 13's, but I never saw it happen. The magazines were getting mid 14's to low 14's. That's what I'd expect a stocker to run. With the CAI and catback, 14.0

 

whats a simple mod that would get me under 14s in 13s?

 

Change the rear gear ratio to 3:73 or 4:10. Most guys with Auto's like the 3:73 gear.

 

wheres that going to put me with 3.73s

 

Should be around .5 sec. quicker.

 

A friend of mine went 13.95 @100 with an automatic, 2.73 geared, 1996 trans am. Cold weather. It had a K&N cold air and welded in flowmaster muffler. Funny thing is, it was nearly impossible to do a good burnout because of the gearing. It barely made it to 3rd gear in the 1/4. The 1-2 shift looked to he at the damn 1/8th mile.

In hot weather, stock, it ran 14.4 @97-98mph.

 

Some good soft tires so you can take complete advantage of the available power, and seat time.
