nVision NVB321T 3-Port .21 Tuned Off Road Engine (2012) (Turbo Plug)
This is the nVision NVB321T 3-Port .21 Tuned Off Road Engine. The most unique feature of this engine is the crankshaft counterbalance porting. The nVision crankshaft is a design that is based on patented CRF technology. The crankshaft design forces the fuel through four angled holes in the counterbalance, using the g‐forces to push the gas‐mixture directly into the combustion chamber. Conical inserts in the counterbalance control the flow of the gases and the feel of the power delivery, which can be tuned through the use of different inserts. The result is incredible acceleration and top speed combined with maximum control over the power delivery of the engine.
Other notable features found in this engine include ceramic bearings, a billet aluminum piston mated to a hand tuned 3 port sleeve, a special alloy crankcase and an ultra-light cooling head. Plus, all nVision products are packed in sleek neoprene bags that not only look cool and protect the engines during transport, they can be used to store a variety of items over and over again.
