Reds Racing WR7 2.0 7-port engine

Reds Racing have introduced their new WR7 2.0 7-port nitro off-road engine. It is a 7 special porting extreme power engine based on the WR7 Diamond edition and the power plant comes with the same sleeve and piston, crankshaft, crankcase, etc. as the first generation of the WR7, in order to keep its power characteristics unchanged. However, Reds Racing decided to update the previous version with improved idle stability and tuning options thanks to a new 3-needle setting carburettor, an improved mid to top range power curve and feeling thanks to a special low speed needle and mid range spray bar as well as an improved cooling system specifically developed to widen the operating range so that the engine can work well in extremely hot conditions. Furthermore, the new cooling system has been created to guarantee a more consistent tuning in every track condition. The engine is available with a DLC coated or with standard steel crankshaft and also as pre-broken-in and Racy Ready by EB variants.
