    And not to get OT in my own thread, but why havent you added cams to your track beast?
    Gearing played a small part. Both cars had same transmission/diff though mine had 205 tires while the 3.2 car had 245 tires and a larger overall diameter. On several pulls, my 3.0 would slowly walk away from the 3.2. We didn't 'drag launch' the cars, just ran then from about 10mph in 1st--so I did have the gearing advantage, but was at a disadvantage on traction. Had we tried starting from 2000rpm in 2nd or 3rd, the 3.2 would probably have been stronger.

    Plus, my 3.0's dyno plot shows steady power all the way to 7200. HP peaks at 6700 but is pretty much a flat line to redline. This is helpful when you're rowing through multiple gears. 3.2 car had a passenger when we ran them, so after a few runs we put the passenger in my car and yielded similar results. (edit: meaning i still pulled on him just not quite as much)

    About cams, I pretty much built the motor on a budget when I was in high school, so a $1000 payout for Schricks wasn't really possible. I could probably pick up a good bit of power with cams, but it'd be diminishing returns because the car really needs brakes and other things before it needs more power.

      e30polak, you are thinking of the aluminum m52 found in the 2.8L Z3
      Perot isn't a Hillary hater, but he's not a fan either, relating the bumper sticker he received that reads: "Monica Lewinsky's Ex-Boyfriend's Wife for President."
