i ended up making 606whp on 16lbs, and ran a best of 9.995 at 139mph. best 60ft was a 1.55 (big tire car with 4 link, so it is a horrible 60ft). converter is way to tight and could only get to 2900 (about 300 hp) off the line. got a new crank pulley coming, but think that is going to be it for this year.
