I don't think the "official" WGT rules will change anytime in the next few months. The reason I started this thread was to find ideas on how to incorporate lipo into this class. The WGT rules will stay as they are for large races and at most tracks (from what I hear) for the rest of the "indoor carpet season". In Ohio, the indoor season runs till early/mid April. however, I'm going to start running lipo/17.5 or 21.5 at my local track in January. I may also try single cell/10.5 once more testing has been done with that combination in WGT. I don't get the feeling people want to change WGT over night. We're just looking to the future and slowly trying to integrate change. Slowly meaning in the next year or two. Maybe someone will come out with a 19.5 motor to match the speed of the 4-cell/13.5 cars.......but for now I'm just gonna go racin'!!
