https://www.youtube.com/watch?v=rWmyKp91b8M heres one, there is more on my youtube page. its done this for two years.

itll turn 5000 rpm just drive down track. its as soon as its loaded on track it seems. as on dyno I can run it up to 4500. but the power band on the came maxes out at like 3500 and doesn't make sense to me.

no matter the gear ratio on the track, it will only turn 3600 rpm. it will free rev past no problem, it will go past on a dyno, just doesn't do it on the track. so I wondering with the load and the bigger cam if that is hurting it or not. trying to get it figured out for the spring.
