im finally getting a motor with some decent power(ns3) compared to my omega/picco xt12) but i first have to figure out how to fix the stripped head screw. but i watched an x12 with the same gearing, same car(mtx-3) pull the ns3 down the straight with authority. if they are the same motor, the timing and some other things are definatly different. the fuel was the same(sidewinder 30%) and the x12 was possibly tuned a little better, but not that much. damn, what an engine.
