I'm trying to understand why (or how) a pressure change caused a severe whole kart hop.
I was in a race this past weekend where it was run in 2 parts. 20 laps counter clockwise, a 5 minute break, and then 20 laps clockwise. Toward the end of the 1st 20 lap segment, the kart seemed like it started developing a slight rear hop. Starting pressure was 12psi. It grew to 14psi in this 20 laps. We decided to drop it 1 pound bringing that down to 13psi. After doing this and the 5 minute break, the kart developed a severe whole kart hop in even the long sweeping turns, binding and bogging down in sharper slower turns. I was 1/2 second off from the first 20 laps to the last 20 laps.
I'm trying to wrap my head around why there was such an extreme effect. The thought was that if some kind of hop was starting to develop as pressure was rising that we could drop pressure to predict this.
Can someone help theorize what went on and how 1lb less could have made such a dramatic change?
