To answer some of the questions. It's a glide, 1.76 gear. Leaving off the brake at 4500. 6200 converter. I've tried the rear bar from as low as 1.5" off the ground up to about 5". up. With the bar at it's lowest, it was quick yank up on the front end then instant spin and hard left turn. With the bars up about 4" it's still came up hard, but I was able to ride for 60ft or so before things unloaded and more bad spin. It's was running 5.40's before the timing change. Car should be easily capable of 5.00's or a little better. The one pass I was able to pedal it and get down the track under power it went 5.35 so it would appear that the timing change has helped the hp, if I can just figure out the right combo on the car. I like a car that takes a little skill to drive, but I also like to be able to make it all the way down the track too
