No, the first is about 3,000 and the second is about 2,000. The two are not really apples to apples on rpm nor springs/shocks, as the second video is on the monos with the shocks set at 8. The first is 6 cylinder springs/shocks set at 6 and spring just touching the pin. I will try to post a video with the old springs and a gap (no pre-load) to get a truer apples to apples. Even with the same spring/shocking setting and rpm, the difference in separation prior to launch is pretty significant. The preload really seems to make a difference.

Thanks for the info . I'm getting ready to tune my CalTracs again...first outing broke my spring perches and bent the rear housing. I almost have it back together again, but this time with a MO875 and a back brace.
