Japan’s Nuclear, the brand of multiple Worlds Finalist Masao Tanaka, has released the latest addition to its ASM range of .21 race engines with the new Ultra Torque. Designed with an emphasis on medium to high speed circuits, in addition to surface treatment processing such as WPC it has also undergone special processing for increased piston strength. The sleeve, connecting rod and piston pins are also surface treated helping to reduce all friction resistance.
