Nitro Engine ZR.32X Spec. 4.1 Competition
The new Spec 4.1 has a new piston and connecting rod design, a competition-specific turbo combustion chamber with appropriate plugs and improved timing, the performance was further increased, especially in the medium speed range. With the new, thermally decoupled 3-needle carburetor, an even finer tuning of the fuel/air mixture is possible for a more efficient burn which results in slightly more power over Spec4. The included aluminum venturi inserts in 9.0/8.5/7.5mm make the tuning options perfect.
The ZR.32X Spec 4.1 engines come incl. a free LRP Turbo WT4 glow plug.
The Spec 4.1 was race tested by our own team driver as an assurance of real-world basher and racer’s application and tuning.
