Star Motor Engineering have been in contact to let us know about their new 3.5cc on road engine, called the S21 CL7 R. This 7 port engine uses ABC construction and is of the same quality level as the company’s CL7 R STI, coming supplied with a rear ceramic ball bearing for high performace and reliability. This motor is aimed at racers that want a reliable, easy tuning engine, while retaining the same technology that has won 2 World titles in this class.
Sirio Engines have announced that their new S12 T3 EVO4 STI engines will include ceramic ball bearings in both the front and rear of crankcase. The use of ceramic balls is said to provide better reliability and performance of the engine and these bearings use only the ceramic balls, which makes them also extremely light. Available seperately, they can also be used in all of the company’s S12 T3 engines that have a 12mm crankshaft.
On Saturday we showed you the first pictures of the new Sirio BK Evo4 STI, spotted while track testing in Italy. Sirio have been in contact since and were kind enough to supply us with the first pictures of their .21 range of engines for 2008. As well as the green headed BK Evo4 STI (above), the new line includes other buggy motors such as the CL7 B, the CL7 B STI and the magnesium headed version of the BK Evo4. For circuit racers there are 2 motors to choose from, the RR STI and the CL7 R STI. Later this week we hope to bring you more information about the new Sirio engine line, as well as internal pictures of the motors, taken at the Nuremberg Toy Fair in Germany.

Current British 4wd electric buggy Champion and World and European finalist Lee Martin has signed to use Sirio engines. Lee will make his debut with the Sirio 21 CL7B-STI in Florida next month when he will run it in his Associated RC8 1/8th scale buggy. Lee had this to say about the deal:
I loved the Sirio 21 CL7B-STI! It felt instant and smooth! Gave me a greatly increased confidence with engines and can’t wait to use this at the next meeting I attend. I think the EP guys will prefer this pipe S21.200123 (EFRA 2057 high torque with smooth mid range power) on clay or dirt surfaces. I would like thank Sirio & Kyosho UK for their support.

Sirio have released their new power clutch set that is suitable for use with the Xray NT1 and the Kyosho RRR range of 1/10th scale cars. The bell housing (above) is sold as part of the set and features cooling fins that allow the temperature of the clutch to stay low without the removal of material which could compromise strength, and reduce clutch shoe contact area. The bell housing is also available seperately and doesn’t come supplied with pinion gears, those that come with the Xray and Kyosho will fit.
