Mod Results
I have recently put some basic mods on my 02 A4 and I wanted to share how they did. I installed a vararam intake system, ported and polished the TB, tuned with hypertech, and put on a Borla catback with full mufflers. Wow! what a difference from stock. My car feels quite a bit faster. From a dead stop with no TC on It will just spin through 2nd. Traction was never an issue before, but now it definitely is. My car feels quite comparable with my friends 02 Z06. What kind of HP do you guys think I might have gotten.

I would guess about 25 -30 RWHP( that is on the generous side) I really don't think you are in the same ballpark to keep up with a z06 unless your a4 was a s4 and had about about $10,000 in mods then you will be about even

SOTP performance gains can be very deceptive. I also doubt that you are in the same ball park as a well driven Z06 with the mods you have. Install a good high stall converter and some gears (at least 3.42s) and you will take a big step up in performance.

But if you do some basic additional mods you will be even with a Z06 2003. Using the same mods + 3.42 gears and a SY3500 (stall 3500) TC, I would take a Z06 out of the hole and he would never be able to catch me by the 1/4 mark. The Z06 was always trapping faster then i was though by about 4-8 Mph. The Z06 therefore had more RWHP then I but my vette was quicker not faster.

I agree ZO6's are a great car.. but lets not think other cars cant stay with them...
I'm not trying to put down ZO6s but look at my ET with a STOCK LT1 A4 .. I still have the stock exhaust manifolds & cats on my car !

You probably picked up 20 - 30 rwhp with your VaraRam, ported TB, and Borla cat-back. I wouldn't get cocky with a Z06 - provided he knows how to drive he will stomp you. The Z06 has better heads, cam, gears, etc, etc, etc ..
I agree, but, keep in mind if you're trapping at 110 MPH a Z06 will easily beat you on the street. Running low 12's at 110 MPH is doing *very* well.
Cheers,
Mark

It onlt took us app. $2500 IN MODS (ALL BOLT-ONS....NO HEAD/CAM) to get into the high 11's.
