Dry-Sump System |
|
Paul’s expertise as a development engineer means that the Caterham FireBlade has many unique items developed especially for it. Not least amongst these is the dry-sump system, which comes as standard - Paul insisted on this because of the FireBlade engine’s high output of 150bhp/litre combined with the Seven’s ability to produce high lateral g-forces. Without a dry-sump system there would be an increase chance of oil starvation, which is not desirable for an engine that revs to 11,400rpm. This isn’t a problem in the bike since the cornering forces always push the oil down into the sump as the bike leans into corners. |

The bespoke dry-sump is machined from lightweight aluminium billet and uses three pumps, the original Honda item for pressure and new twin scavenge pumps, which take oil from both sides of the sump avoiding any problems associated with constant cornering, especially on a long corner. In addition, the dry-sump gives better ground clearance whilst also allowing the engine to be positioned lower in the chassis, improving the cars centre of gravity, and maintaining the traditional Caterham bonnet line. |

The engine featured here is equipped with ultra lightweight NOMEX Oil Hoses - see options list. |

All the items required to fully dry-sump the FireBlade engine are included in the Starter Kit. |
