Nitro Motor ZR.32X Spec.4.1 Competition
How do you improve an extremely good product even more? You let the experience and voices of the customer influence the design allowing the product to constantly evolve! We are proud to present the successor to the ZR.32X, which is especially popular with monster truck bashers.
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.
