I think I’m a fast learner.....
I can’t get this stuff out of my mind
I had to rescale and add 20#. Using bathroom scales, a 6’ level and printer paper to adjust.
In practice we used the tires we ran the night before and ran 13.80 lap times. Kart would’nt turn and get off the (Flat tight corners)
Heat race it was even worse. 14 seconds laps.
3.3 psi left
4.3 psi right
front stagger @1.25 inches was off. (math error) I may need to use mm’s to keep from doing this again.
Going into the feature, I knew my stagger was a problem. I raised my stagger to 1.5” front and kept rear at 1.0” rear. We hadn’t lost any traction all night. I didn’t add any bite. Zero but I wanted to free the rear end up.
Front psi raised from
3.3L > 3.5 right
4.3 > 4.6 left
rear
3.3 > 3.8L
4.3 > 4.8R
Started the feature 7th and raced up to 3rd before getting passed toward the end. The kart improved but was still not turning like the leaders.
Everyone says tires tires tires....
here are my numbers on the official track scales which am told are very accurate.
FL 65# FR 87# Front 47.6%
Left 57.7%__cross 64.6%__Right 42.3%
LR 119# LR 48#___ Rear 52.4%
PRC’s tech guys words are echoing in my head. PRC told me that if I got good bite, good tire program that I can run up 68%~70% cross.
I don’t know if I locked the kart up. I don’t know if I over prepped my tires, don’t know if my duro was too low? Punched .46
or should I have had more cross% and more weight on the front right?
or .....
