The New Swiftune SW8 Billet Camshaft
The all new SW8 camshaft has been designed to fill the gap between the legendary Swiftune SW5 road cam and the equally popular SW10 (which is similar to a 286).
This will suit the customer who wants a more powerful cam without taking the large step of using the SW10. We have delivered extra power but, keeping the requirements of road usage in mind, the SW8 easily achieves the MOT emissions and during Dyno testing at wide open throttle, it would pull down to 2300rpm.
The dyno test figures we achieved were from a 1380cc unit which was fitted with twin 1.5 SU carburettors, 1.5 ratio rockers and a Mini Spares cylinder head using 35.7 in and 29.5 ex valves. These were deliberate choices to replicate the specification that many home tuners might use when building their own Mini and Midget. our test engine also delivered 110 bhp at the top end.
On the technical front, this cam has been developed on the latest Lotus software. They are cross-drilled and produced from a steel billet using state of the art CNC machining.
The characteristics of this camshaft make it suitable for engine sizes of 1275 upwards.
