This is the Jammin Products .28 off-road truggy engine by OFNA. Jammin Jay himself did the R&D on this engines and paid special attention to the details that are so important for off-road R/C racing. Such as durability, ease of tuning, and driveabilty. Tweaks to the materials, crank timing, and tolerances all played a part in getting the engine to the high performance edge that Jammin Jay requires. The OFNA Jammin .28 engine delivers excellent bottom end power with great top end run out and includes a Turbo Plug type head. The Jammin .28 is all out big block performance but still very easy to drive and gets surprisingly good fuel mileage. Turbo Glow plug included. Made in Italy.
These engines run best with a hot Turbo plug, such as the OFN51006 plug, an O.S. P3 plug or a Novarossi C5TC or C5TF plug.
