If speed is your vice , then RB have developed a fix. The new V15 features the same design attributes of the V12 but it produces the sort of power associated with a Big Block .15 engine, but housed in a small block case. Not suitable for legal races, but then who gives a damn!

Crankcase
The new crankcase is made of alluminum with casting procedures. The design has been made to obtain the best rigidity possible (engine mounts, reinforcements) and a the best cooling with additional ribs. Rigid, the new crankcase of the RB CONCEPT V15 series improves the mechanical efficiency of the internal components. The fixation of the carburetor provide a very reliable attachment with low possibility of damage of the carburetor.

Porting
If you look attentively at the shape of the transfers in the crankcase, you can notice the presence of a small separator in the middle of the side-ports, this separator increases the speed of the gasflow just before entering in the cylinder for a better filling. The porting is made to fit perfectly with the porting of the liner.

Piston Liner
The drawing of the porting gives the best balance possible between torque and high rpm. The machined piston is perfectly adjusted to the liner in order to obtain the best efficiency with the lowest fuel consumption possible. Of course, the V15 series keeps their legendary qualities of reliability and lifetime as all the RB CONCEPT engines. The liner fits smoothly inside the crankcase and the ports of the liner are perfectly lined up with the ports of the crankshaft.

Conrod
The conrod is manufactured using a special strong and high quality aluminum and checked by ultrasound. With its special aerodynamic "knife" shape, the weight is reduced to increase the accelerations at low rpm and to optimize the internal gas-flow. Due to the two bushings in bronze, the conrod is perfectly lubricated, even if the engine is working under heavy racing conditions.

Crankshaft
Result of a long experience with high competition racing RB CONCEPT engines, the new improved crankshaft "Bi-Turbo" of the RB Concept V15 is one of its secrets getting available a usable powerrange. Its special and unique design has not been equalled. The shape of this Bi-Turbo crankshaft is also designed to be fine balanced and to increase the efficiency of the gas-flow.

Bearings
The use of high speed ball-bearings is what we have found the best for the RB CONCEPT V15, the front-bearing features a rubber shield to prevent dust from coming into the engine while the main-bearing is also a high speed type for very high performances and reliability.

Cooling-head
The V15 series are very easy to recognize with its orange-gold cooling head, nicely engraved with the V12 logo. Due to 4 additional slots machined on this head, the RB CONCEPT V15 series can be easily removed from its engine mounts.

Carburetor
The carburetor of the V15 is an aluminum type for more stable and easy adjustments. It has an exclusive system of removable venturi (supplied with venturi 6.5 diameter) which allow to change easily the diameter of the carburetor (optional 5.4 mm & 5 mm).

Glowplug
The Turbo glowplug delivered with this V15 engine is specially adapted for this type of engine.
