More Power Needed, Help Me Out. Currently Have 400RWHP 379RWTQ
Like the title says I am looking to get a little more power out of my car.
The car is a 01 A4 Z28 that has 400RWHP/379RWTQ. I have Absolute Speed heads 10:8:1, TR 224/224 563 on a 114 cam, Fast 78mm intake and throttle body, 2800 Stall with 2.5str.
The car runs 12.1-12.2s but I am looking for mid 11s. I was thinking of bumping my cam up to a 580+ lift cam on a 112. I figure that would have to be good for soem additioanl PWR. I was looking at a STS turbo but it is $5,800 with a tune, Meth injection, injectors and a fuel ssytem upgrade.
I really don't want to do NOS.
Just wondering what peoples thoughts are for this? I may still end up with the STS Turbo kit if that is what it will take. I just hate to have thta much cash tied up if at all possible. I am also going to bump my converter to a 3800 stall.
Thanks for your input.

I say get a bigger cam and stall and you will see mid 11's. Same maybe something in the mid 230's/230's and you should certainly see big diff in your numbers and the stall should def make good use of the power. The STS kit isnt bad but its gonna cost you a lot more going turbo than just the cost of the kit. Turboing a car is so expensive, I would say just go bigger cam IMO.

The car ran a best of 12.1 @ 112mph with a 1.75 60'.
By the way, the car is running 275/40/17 Nitto Drags.
Thanks,

If you are going to put in a new cam you should think about a 231/237 type cam. With your stall and gears that power would be very uesable.
Just for reference: I have the TR224 on a 112 with PP stage II's, dynatech LT's that put down 395rwhp and 370rwtq through a M6 and 10 bolt. I don't have the FAST or pulley, but notice the similar setup yet you make more through an A4. Yet your ET and trap seem low for the power level.

Again I vote for bigger cam and stall. No need to go with something huge like a TREX or MS3, but you could easily run a 228/228, 230/232 (similar to an FM13), or something in the low to mid 230's intake and duration and with a good tune it will have great street manners. You would probably see around 425 rwhp and with the larger stall i think you would easily make it into mid 11's. As someone else said the stall alone will get you into the 11's, but a bigger cam would probably get you mid to low 11's IMO.

I know Bill, and for the people suggesting X3/4's or TREX, trust me he doesn't want THAT big. I'd say upgrade the cam a bit, maybe around the size of my F13, which is a great cam for a daily, and the addition of a 90/90 setup. Do those along with possibly a stall and I'd think you'd be mid 11's.
I also just noticed that you're running mid-length headers with cats. You could switch those out to a long-tube setup with high flow cats in addition to the above.
I'll be back up at work in mid May if you want a ride in my car to see what the cam acts like, or if you want help installing parts.
