In 1982 HKS introduced the world's first Turbo Timer to assist in cooling down the turbocharger to prevent oil coking in the centre bearing cartridge assembly. Oil "coking" occurs when a turbocharger is not properly cooled down and the oil that normally lubricates the centre cartridge heats up and forms solidified oil deposits. A turbo timer allows an engine to idle for a preset amount of time after the ignition key has been turned to the off position and removed. By allowing a turbocharged engine to idle, oil continues to pass through the turbo until it has cooled down to the point where oil "coking" will not occur. Re-designed for 2008, the all new Turbo Timer Type-0 and Type-1 feature a new, slim low profile design with a separate LCD display and control unit following the same design concepts as the current HKS EVC and A/F Knock Amp.
The Turbo Timer Type-0 features a red LCD backlit display for easy visibility, 2 timer modes, and a battery voltage meter with a peak value indication and warning function.
The Turbo Timer Type-1 features a light blue LCD backlit display and has the same basic timing and voltage features as the Type-0 plus several monitoring and measurement functions. The Turbo Timer Type-1 features an Auto mode for the timer function allowing the Turbo Timer to automatically calculate optimum idling time according to the most recent driving pattern. Vehicle speed and RPM can be displayed on the Type-1's LCD monitor and a speed warning level can be set. A two-stage RPM warning can also be set and used as a shift indicator. When a warning level is reached the Type-1's LCD monitor will blink and an audible beep will sound. The HKS Turbo Timer Type-1 also features various measurement functions including 1/4 mile timer, 0-60 timer and a stopwatch function that can be used for lap timing. The Turbo-Timer Type-1 can read in either MPH/SAE or KPH/Metric.
The new HKS Turbo Timers are compatible with all HKS Turbo Timer harnesses to make for an easy installation.
