Rb Cb66 T7

The RB Concept C6BB is now as popular as the world famous and 3 time’s world Champion RB Concept WS7III! This engine drives the racers crazy during the international events with its wide power band and incredibly smooth accelerations.

For the international team drivers it is the best off Road engine ever designed! During the year, they made thousands hours of test to prove a new combustion chamber with turbo plug to improve the overall yield of the engine, and a 7mm ventury to improve traction. With these features, the fuel consumption drops and the drivability is increased specially on the low traction tracks. This helped the International team to catch most of the national and international events all over the world.

That's why RB decided to add these features to its world famous RB Concept C6BB and released the RB Concept C6BB 7T in order to offer to anybody the opportunity of driving the same engine as Guillaume Vray, Yannick Aigoin, Daniel Reckward, Linus Thern, David Crompton..... or yourself!

This new C6BB T7 crankcase has been designed and developed by Rody Roem. It is light, rigid and strong to achieve optimum performance. The crankcase material is a highly developed alloy, which provides greater stability. It is formed utilizing a vacuum system, which avoids the creation of air cavities during the moulding process.

The internal porting of this new crankcase has been improved and optimized to provide a more efficient gasflow in combination with the 5 intake ports of the sleeve. Included in the crankcase carburettor spigot you will find an o-ring system which prevents the carburettor o-ring from being damaged when removing and assembling the carburettor from the crankcase.

The piston and sleeve combination are "ABC", which is short for Aluminum/Brass and Chrome. The piston is cast from aluminium and the sleeve is a brass cylinder that has been hard chromed on the inside to provide superior life. You will also notice the porting of our Multi Exhaust System (MES), which was originally an RB innovation and has now been adopted by most of our competitors. The sleeve itself has a total of 9 functioning ports. There are 5 intake ports and 2 bypass or scavenging ports, working along with the additional 2 Exhaust Booster ports, which help to create improved fuel consumption, while giving unmatched power also. The C6BB T7 comes with a redesigned Multi Exhaust System creating high torque even from low RPM thus ensuring incredible acceleration from this Buggy engine. Despite the massive horsepower available from the RB CONCEPT C6BB Turbo the fuel consumption is also more than acceptable!

This multicomposite carburettor is mainly made out of nylon to prevent overheating of the fuel entering the engine (vaporlock) when the engine is very hot. The base of the carburettor has a new steel insert, which goes through to the top of the housing, so that its strength and stability is assured. This carburetor is supplied with an 7mm venturi and can receive the following venturis of 6, 8 or 9mm diameter depending upon the power you need and fuel consumption you want to obtain. The idle screw has been repositioned and the slide is now easier to connect to the throttle linkage.

Very Nice Engine
