O.S. have announced 2 new engines to fill a vital niche in the stadium truck market with the release of the 12TZ (P) and the 12TG-P. The 12TZ is a turbo engine with a 3-port ABC liner and 3-needle rotary carb, for optimum adjustability, and this motor meets all IFMAR and ROAR 3-port specs. The bore and stroke of this motor provide the widest possible power band and with it the ability to adapt to any track. The 12TG-P is also a ROAR legal motor and works well in cars like the Associated GT2 and HPI Firestorm, and like all 12TG engines it’s easy to break in and very economical, expecting to get up to 14 minutes of run-time on a single tank of fuel.
