SW23 Camshaft

SW23 – The most successful Historic race camshaft in the world!

We developed the SW23 cam for our own Historic FIA race engines and its proved to be very successful by winning all the major races including the 3 Goodwood all Mini races over the last 12 years. Also used in many of our other race engines from Formula Junior to Hill-climb 1380’s.

This incredible win rate has proven that its not just from the top-end power figures but an impressive spread of power over the whole rev range. The old saying “torque wins races not just power” still stands and the records prove this!

Power graph #1 shows a typical Historic FIA 1293cc race engine running with H4 twin SU’s topping out at over 130 BHP @8000 RPM and pulling strong from 5000 RPM. On the track this will pull from 4500 RPM

Power graph #2 is a typical 1380 race engine running with a 45DCOE weber. Peak power of over 140 BHP and pushing 110 FT/lbs of torque.

The success of the SW23 has led to many other engine builders using this profile. Trade enquiries always welcome.

All SW23 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 race profiles which eliminate excessive grinding and removing the vital surface hardening. The end result is a camshaft with deeper surface hardening and superb wear resistance to add further durability the SW23 is Tuftrided after final grinding.

The Swiftune SW23 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 SW23 is Swiftune's exclusive design and is not available from any other source.

Why use anything else?

Swiftune Followers
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.
