REDS Racing 521 GTS GEN2 1/8 Nitro Truggy Engine

From REDS Racing:
REDS Racing is excited to introduce the new 521 GTS GEN2 engine specifically developed for 1:8 nitro gt class. The new 521 GTS GEN2 engine features high power, tuning stability and great fuel mileage. Combined with specific technical changes at the carburetor, combustion chamber and front bearing, this 5 port engine features higher power and better fuel efficiency compared to any other engine.

We developed 3 different combinations for this engine: 521 GTS with steel bearing, 521 GTS with ceramic bearing and 521 GTS Pro Tuned by Mario Rossi with ceramic bearing. You can order all of them with or without pre break-in service.

Available Models:

ENPS0015B 521 GTS STEEL GEN2 – Pre break-in service by Mario Rossi
ENPS0016B 521 GTS CERAMIC GEN2 – Pre break-in service by Mario Rossi
ENPS0017B 521 GTS PRO TUNED GEN2 – Pre break-in service by Mario Rossi
ENPS0015 521 GTS STEEL GEN2
ENPS0016 521 GTS CERAMIC GEN2
ENPS0017 521 GTS PRO TUNED GEN2

What is new and different?

New CG3 Carburetor: The biggest improvement is the brand new aluminum carburetor made from pressure die casting. The new GTS comes with a completely redesigned 3 needle carburetor for better and easier tuning in all conditions. Furthermore, thanks to its mid range needle, this carburetor guarantees more linear power delivery and greater power.The new carb has been specifically designed to fit the INS BOX homologated by EFRA and IFMAR. To match all the above features and improve product quality we have made a brand new die casting tool.

New Combustion Chamber: The new 521 GTS comes with a completely redesigned combustion chamber to improve power delivery especially at low RPM (torque). This engine can work with both 16EU and 25% nitro fuel.

New High-sealing front bearing: The new front bearing guarantees better sealing and high RPM range. The new front bearing assures a better idle stability since the rubber seal reduces leaking. Furthermore, thanks to this new bearing the engine and consequently the bearing itself is more reliable.

Furthermore, we have developed a new pipe kit for this engine. The new pipe kit comes with 2113 pipe and a conical manifold to optimize the 521 GTS GEN2 power curve.
