JUN had developed JUN HYPER LEMON R III which carried RB26DETT engine to participate in 1997 USA Bonneville Speed Trial. In a F/BGCC class The new record of 383.715 km/h was achieved and we became a world champion splendidly. Although the engine power was over 1000PS, it proved the durability which bears the continuous full throttle in 2 minutes. We feed back such technology to a user and high quality engine processing is offered by JUN.
As for the head portion of RB26 engine, the cooling-water-line which continues from the burner upper part to an intake port side is very narrow on structure. According to circumstances, the water line is closed. At JUN, the trouble by water temperature rise is prevented by performing original processing to that portion. In addition, we have much original know-how about RB26.
