I have a 99 Trans am A4 with 50,000 miles on it. Will The coolant bypass, egr mod, air box chop, lid, filter, maf, spark plug wires, throttle body velocity stack, and an exhaust cut out get me into the 12's? Thanks in adavanbce for the help 12's are my goal for high school, and then the big mods come.

Throw on some decent tires and you got 12s easily.

i disagree with this statement.

more often than not, full weight automatic cars need 1 of 2 things to go 12s in stockish form:

headers

stall converter

with the mods you've listed, i would guess a 13.1 at best, assuming a decent hook.

Realistically, I doubt you'll see 12's. If your car was a 01+ and tuned I would say it's possible. Torque management really held my car back. Before tuning I was running 13.0s. I went 12.8@108 with a lid, cutout, and tune in almost perfect weather. What gears do you have? Goodluck.

I dont think you will see 12's with that setup. But you can do low 13's. A stall would really help you. Another cheap but good mod is porting your throttle body.

That setup is probably only going to net you a 13.2-13.4 and that's with a decent launch. I too have a 99 A4 so I know how much the stock manifold, stock converter and stock weight hold us back.

You will need to add LT headers, ORY and probably a tune in order to see high 12's. Or you could get a 3000-4000 stall torque converter, tranny cooler and drag radials to see high 12's. Get them both and see my sig

That's at 900 feet elevation BTW so you may have to adjust up or down depending on how the elevation is at your track.
