Ultimate Racing have introduced the ‘Team Edition’ version of their previously released M5S Ceramic engine. The ‘Team Edition’ concept uses the same Ultimate engines that are for sale, but the engines are assembled directly in their factory, completely broken-in and then thoroughly checked by their competition team to extract 100% of the performance from the engine.

Having previously teased the new K303 engine, FX have released some further details on this new .21 buggy motor. With a focus on longer runtime, this 3-port motor has a DLC coated crankshaft which has been balanced with two tungsten inserts and comes as standard with a ceramic rear bearing.

From AEA Performance comes their new 1/8 Vartax clutch system. This new clutch system uses 4 channels in the flywheel, along which weighted rollers run and engage the clutch plate. This gives you a very strong clutch engagement as well as consistent function throughout its use. The setting of the clutch can be changed through the use of different rollers as well as through the clutch spring itself. The flywheel as well as the clutch plate have been machined from high quality 7075 aluminium.

The new motors continue to come from FX Engines with another new teaser, this time for the K303. Again we have little information to go on, however the name would suggest a follow up to the previous K302.1 3-port buggy engine, while the silhouette also points to a new cooling head. We will know more soon enough.

Hasi Tuned have released 4 new manifolds for .21 engines, the first of which is a conical manifold that guarantees easy tuning and low fuel consumption. This is great for middle fast track were there is normally high fuel consumption. The 2nd is a conical 90° version and offers more torque in the low and middle rpm and is a perfect choice for fast tracks. The 3rd version is a conical 90+90 and has extreme torque making it a good choice for super fast track and there is a 4th version which is slightly longer for a little bit simpler tuning and with less consumption than the std version.
This is the new iRacing GTX5 .21 GT engine, based on the well known O.S. R2104 engine. The motor sports a new crankshaft with redesigned counter weight giving the engine better balance and has been given a special DLC treatment for longer life. It boasts 5-port line for improved torque in the low to middle power range giving lots of power, even in high traction tracks. The new cooling head comes in a silver finish and has been machined to reduce weight while the cooling head button now sports a silicone O-ring to prevent dust from entering the engine.
