Nitro Engine Z.28R Pullstart Spec.3
There are many big block monstertruck engines available on the market. But the least of them are as successful as the LRP Z.28R Spec.3 Pullstart. Its wins are uncounted. E.g. it finished in first place at all Monster Mania events in the last years.
With its 3.89HP and a maximum RPM of 33.500 this engine is ideally suited for monstertrucks on every kind of terrain. The throttle response and the power band are specially optimised for trick jumps and races on off road tracks. Due to its compact construction the engine can be used as a direct replacement to the .21 and .25 engines.
