Although we have race specification camshafts, a very small number of customers require very specific engine characteristics. One type of specialized camshaft was developed for Time Attack where the engine performance "below 4000 rpm is not required".
With the customers' requirements the Hyper-One camshaft Pre and Sec cam lobes where redesigned to be more closer to a Mid cam lobe in design to maximize the mid-range performance starting from 4000 rpm. With this design, new gains in the torque band and power curve of the mid-range to upper revs were found, via the use of Racing VTEC.
Manufacturer Notes:
*One prerequisite for using Hyper-One camshafts is that they have to be used in conjunction with Sports Injection KIT (individual throttle bodies). Operation of ECU recommends by throttle speed control. This is due to the very unstable nature of the airflow while idling, that the single throttle body will find it difficult to control.
*It is recommended the switching on of the VTEC should be at 5850 rpm, and the switched off at 5600 rpm for the best performance results from the Hyper-One camshafts.
*On installing please check valve to piston clearance, valve to valve clearance, cam lob to follower clearance during mid cam operation.
*Caution: finger follower (roller rocker-arm) may need modifying due to contact with the cam lob.
*The cam angles for Primary, Mid, Secondary are indicated.
*Standard valve spring cannot be used
*TODA Up Rated Valve Spring required.
*This product must be used in a set of intake and exhaust camshafts.
*This product is recommended to use in conjunction with the following Toda products: Sports Injection KIT, Free Adjusting Cam Gears, Heavy Duty Timing Chain, Heavy Duty Oil Pump Chain, Heavy Duty Chain Tensioner.
