Gimar Saturn 9 Evo .21 nitro on-road engine

Gimar have introduced their all-new Saturn 9 Evo .21 nitro on-road competition engine built from OS. The power plant utilises the new patented M.E.S. (multi exhaust system) sleeve, which has 9 ports with 4 exhaust booster ports and the special shape ensures maximised performance. The crankcase is specially machined from OS to work perfectly with the 4 booster ports sleeve and the crankcase has been hard black coated to increase hardness and stability. Also new is the DLC-coated crankshaft with triple tungsten balance weights and silicone insert. The updated design optimises internal mixture flow while the lightweight shaft improves agility. While the 3-needle carburettor allows for better idling and quicker returning to low RPM after throttling. The engine’s features are rounded out by a new combustion camber insert specially developed for the use with 16 percent nitro fuel. A 25 percent insert is available separately.
