The 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 larger 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 or Midget.
All SW8 camshafts are machined from custom steel billet blanks! At the heart of it, a brand new blank designed and produced using the highest quality steel with specific base lobe shapes to suite road profiles which eliminate excessive grinding of race X-drilled blanks and removing the vital surface hardening. The end result is a camshaft with deeper surface hardening and superb wear resistance.
The Swiftune SW8 camshaft was developed using Lotus Engineering's latest valve train computer software to enhance the cam profile. Manufactured using the latest CNC cam grinding technology to much closer tolerances which are so important for achieving the optimum dynamics of the cam profile. The same machine is grinding cams for Top level Motorsport customers worldwide.
The SW8 is Swiftune's exclusive design and is not available from any other source.
Why use anything else?
The same followers we have used in all our engine builds for many years. Suitable for both road, race and everything in between.
For the best quality and reliability, our in house designed followers feature an oil drainage hole and extra length for more stability. Finished with no chamfer around the contact face to give extra diameter.
It is strongly advised that these followers are used with all SW camshafts, they have been designed specifically to suit – providing the best performance and reliability compared to other generic followers.
Please be aware - historically, if any damage is caused to the SW camshaft, it will almost always be due to non-Swiftune followers being used.
