There are several ways to increase the ET.The 2 main ways are more HP and less weight.While I'm enjoying my expensive membership to Jenny Craig,I am approaching the next hurdle of being legal to 8.50.I anticipate that waving finger that will occur at 150 MPH. I have the CM tubing to fab the 'chute mount and will be getting the parachute,release handle and cable from Santa or Hanukah Charlie.I went 6.0 in the 1/8 and 9.3 in the 1/4 with 6 lbs of boost.Me thinks about 10 lbs should get me close to that 8.50,,,,,,we'll find out in the spring.I am going to really enjoy that 8 second time slip
