#15201 - NITRO STAR K4.6 ENGINE WITH PULLSTART

4.6cc/ABC/8 port/8.5mm composite slide carb./Aluminum heat sink head (Purple)/Rear exhaust/R5 Glow plug

标准配件 | 选装件

Available from HPI Racing, the Nitro Star K4.6 engine, capable of propelling the Savage monster truck to speeds of 44 mph and wheelie off the line. The K4.6 is a 4.6cc (.28 cubic inch) big block engine that features a machined billet aluminium heatsink head for extra cooling, dual bushing aluminium connecting rod, true ABC chrome sleeve construction for durability, and a three needle 8.5mm slide carburettor with a composite body for better performance at higher temperatures.

The carburettor features a factory re-set line on the high speed needle and “flushed” needles that make re-setting the carburettor to the baseline factory specifications quick and easy. This powerful new engine has 10% more displacement than our Nitro Star S-25 engine and is rated at 2.9 horsepower! This is a direct bolt-in replacement for the 21BB and S-25 engines; we recommend 17/47 gearing to prevent excessive wheelies. A pullstarter is standard equipment, and the K4.6 is compatible with the #87126 Roto Start System and #87127 Roto Start Backplate.
