tire pressure

Ryan, If you get up to 40+ lbs in your front tires and your average RT's are still slow, consider shorter front tires, higher launch RPM and/or a looser converter. Carb tuning the accellerator pump circuit can also help RT's, giving it more "snap", as well as frame connectors, torque strap to limit engine movement, aluminum or poly front spring eye bushings, more air in the rear tires IF you don't compromise traction (contact patch), but a wider rim with the same width slick can allow for more pressure to be run, and probably a few other things. Every little bit helps.
