Back at 2011 we decided to lunch a car and engine project - called “TX” - where the engine has an CNC machined crankcase and it is structural part of the car. The main idea behind this project was to make the engine as low positioned as possible to reduce the center of gravity of the car and to make the car 100% symmetrical.

The first test showed huge potential of this concept, by winning the 2011 European Championship by Martin Bayer. After the victory we decided to work more and more on this concept before we put it on the market, to be sure that everything was perfect. We decided not to use this concept in 2012 and 2013 at Big Races, where we run the T series cars (T12 and T13) instead of the Tx series car. But our development continued in the background and specially in the second half of 2014 and during 2015 we redesigned several time the engine and the chassis until it got its final shape. The 2015 European Championship was the last big test of the completely redesigned Beast engine and the Tx chassis, where it showed its potential against the best drivers, cars and engines all over the world in an sweltering heat (35+ degrees). The Tx chassis and the Beast engine proved their power during this event by making track record and winning the 2015 European Championship by Ales Bayer. The Beast engine was one of a few engine in the Austrian summer heat that had no problem with overheating and had no problem with fuel economy.

The Tx conversion kit allows you to put our all-new Beast engine to any RS5 Touring car from T12. The main advantage of the Tx seriers chassis compare to T series chassis are the followings:


Perfect symmetricity

The side part of the Beast crankcase are made of 7075-T6 aluminium and has the same bottom mounting points as the left side engine bracket, to make the engine structural part of the car. All the bottom mounting holes of the Tx chassis are 100% symmetrical. The standard Zenoah engine has a mass-produced mold cast aluminum crankcase and its tolerances are high. Sometimes these slight tolerance issues generates bending, so owners have to re-tweak the chassis after mounting the engine. The CNC machined 7075-T6 alloy crankcase is a way stiffer than a mold cast aluminum and provides symmetrical mounting points, which leads to an "easy to drive" chassis.

Lower center of gravity

The Beast engine sits 6mm lower on the Tx series chassis than the standard Zenoah engine on the T series chassis. This means the Tx car has lower center of gravity and this gives you advantages at fast direction changes and the car has less tendency of grip rolling at high grip conditions. Because of the low center of gravity you can use softer springs and anti roll bar setup because the car roll less. With the softer suspension you can use more the curbs and the car is easier to drive on bumpy tracks.

Engine fixing left side

The engine flange is installed to the left side of the Beast and fixed to the chassis with 3pcs. M5 screws.

Engine fixing right bottom

On the bottom the engine is fixed with 2pcs. M4 screws. The chassis has oval holes, which allows a perfect alignment of the engine.

Engine fixing right front

Right front fixing points of the engine are two adjustment screws with hexagon head. With them the the gap between the engine and the engine fixture can be fine tuned  to let the engine properly aligned.
