Under the technical supervision of Italy's Mario Rossi, GRP developed a series of tuned
and non-tuned racing engines for 1/8-scale Buggies and Truggies.
GRP's line of Mario Rossi Tuned Engines is designed using advanced mechanical simulation
software that has the ability to reproduce the effects of high temperatures on engine
components and materials. During the research and development process at GRP, each individual
engine component is tested for maximum function and durability at peak engine performance.
GRP uses the finest materials available for their tuned engines, to guarantee the maximum
amount of performance and longevity under the most intense racing conditions.
GRP's line of non-tuned engines represents a high-quality line of Italian-made engines
at a lower price. All of the components used in the non-tuned engines are interchangeable
with the parts used in the tuned engines. This allows the engine to be customized for
increased performance, while eliminating the need to purchase a new engine.
Losi is proud to offer these racing engines from GRP. We also look forward to the
continued success of Yannick Aigoin, Adam Drake, Mike Truhe and other world-class drivers
who will be dominating the tracks with Mario Rossi-Tuned engines from GRP.
