You may want to check out the general nitro talk forum before you break in the WS7II. My brother and I just broke one in week before last using Bess's heat cycle method and it is ripping. My Mugen starter box still has a hard time turning it over and it has about 1.5 gals through it. Another guy at the track used RB's recommended break-in procedure and his is noticeably not as strong, but it has about 3 gals through it also.
