I went a couple of weekends ago and ran a 16.2 1/4. I only got to run once due to the jr. dragsters taking up the lanes. Mine is stock except for a K&N 4.8L 2002 RC Sportside/stepside 2wd. I think it was a 2.5 60' but it wasn't hard to get traction.
Engine and turbo go on in a couple of weekends. I'd be interested in what you do and the times you get. I also want to mod the supension like you posted in another thread.
