All production is done in house, so a high standard of quality is assured.
Opening Valve Rate Improved – By improving the opening valve rate via the smooth acceleration and the smoothing of the transition from closed to open the period of time that the valve is open for is greatly improved. So by using the principals of quick but smooth actions more air can be drawn through the engine.
Non-symmetrical – The cam profile of both the opening and closing phases of the valve lift are not symmetrical, as the closing phase is extended slightly reducing the impact of the calve when it returns to the seat. Making the valve return quietly to the seat, reduces friction, improves reliability and at the same time reduces valve train noise.
Material Quality – We do not only pursue improvements in power output (via, mechanical design) but we also pursue material quality, in particular the relationship between the contact face of the cam, rocker arms and cam followers, so helping to reduce friction further. We also conduct research into the thermal process on the surface of the cam.
All this data forms the basis for the production of many prototypes where bench tests are carried out alongside actual racing. With everything done in house there is no room for compromise and so you can only benefit from our constant search for improved performance.
Up until now, tuning specialists have had to use the standard timing chain. Now there is a product that after reviewing the design and detailed modifying has gained improved accuracy and durability. This is TODA Racing's Heavy Duty Timing Chain.
With the extra demand of hi-performance driving even with the standard road engine and/or components such as camshafts that place extra stress on the valve train system, improved chain strength is important.
The highly precise side plates reduce friction and improve the revolution fatigue strength by increasing the area of the plates, a reduction in the burrs and the finish to each individual plate.
Moreover, due to the higher precision of manufacture, the hole size and shape in the plate have enabled the use of a larger diameter pin, this also contributes to reducing the stretching of the chain under constant high velocity revolutions by as much as 35%. (From Manufactures data)
To attain the most from the improved durability, reduced friction, improved camshaft timing accuracy, we recommend using the TODA Heavy Duty Chain Tensioner (K20A/K24A or F20C/F22C), in combination with TODA's Heavy Duty Timing Chain.
