XS Longtubes/ory/catback
XS Longtubes/ory/catback We got a good solid tune on the car last night. We had made some quick adjustments at the track on Sunday, and we were surprisingly close as you can see by the baseline. I'm sure the stock tune would have been about 10-15hp lower than our starting baseline. Car is an 02 Z28 A4. Mods are XS Stainless Longtube Headers, ORY, Hooker Catback, and LS1Motorsports Lid. I was very happy with the results. I was definitely not expecting numbers as good as these.
342.7rwhp and 359.1 torque. Not bad for a car without a ported tb/smooth bellow/underdrive pulley/etc. I think I have another 10whp or so with just simple add ons.
This confirms that the 28" tire on that heavy 19" wheel is killing me at the track. My best pass on Sunday was a 12.99@108. I think I have the power for a mid to low 12 as it sits right now. I'm going to be getting some 255/50/16 drag radials to put on my stock wheels for my next visit out to the track. I don't think 12.50s is an unreasonable goal.
