OS Speed VZB V-Spec Alu

Neo Buggy have some news from World Champion engine maker O.S. about their new 3.5cc VZB V-Spec Alu headed buggy engine. The engine appears to be the same as the magnesium headed VZB, however features a more conventional aluminium head for those racers wanting the power of the V-Spec but on a tighter budget. The head’s styling also differs from the distinctive magnesium version as a result of the heat conduction characteristics of aluminium, which mean a smaller diameter can be used, and also allows for a new engine head shape. The weight difference is also kept to a minimum with the alu head only 25g heavier than the Magnesium version.
