Well the X motor ran well this past weekend. I was able to try it out on a large flowing outdoor track. It had 767's and red springs. I geared it about a 6.4FD. It had very nice top end. I still have some tuning to do with it. I think this will be a very good large track motor in rubber tire TC.
yes i tested mine on a small track it had very good rip but no punch
in the coners f-brush and red and red , i will try 4499 red and green
next time but still had better numbers on the dyno after i ran it
