  • DC12V Negative Ground (Operation Voltage: DC10V~16V)
  • Large Capacity Relay Equipped
    Ignition: 25A / Accessary: 25A
  • Stand-by Current: 10mA or lower
  • Operating Temperature: -20~60℃ (-4 to 140°F)
  • Setting Time Range: :1, 3, 5, 10, and 30 min.
Example of One Minute Time Range: Frequent after-idling for daily use.
Idling takes place after street driving, commuting, etc.
It is convenient when a driver has to leave the car right after the engine is shut off.
Example of 3 Minutes Time Range: Effective after-idling after driving a highway.
After idling can cool down the turbine and/or engine oil heated up by continuous high speed driving, and the engine shut off without imposing a load to the turbine and/or engine; therefore, the durability of the engine and engine oil is improved.
Example of 5 Minutes Time Range: Effective after-idling after circuit driving
When high load is applied to an engine, and an engine runs at a high speed, the engine and turbine may become in a condition close to a limit. With Turbo Timer, after-idling takes place even if the ignition is turned off by mistake so the engine and turbine may not be damaged.
Example of 10 Minutes Time Range: To keep the interior temperature when leaving a vehicle for a short time
With Turbo Timer, a driver can lock the vehicle door even while running an engine; it allows the vehicle interior temperature maintain when leaving the vehicle for ten minutes or so while reducing a load to a battery.
Example of 30 Minutes Time Range: To maintain the vehicle interior temperature in summer or winter
Maximum timer duration is 30 minutes. A long after-idling enables the vehicle interior temperature to be maintained for a long time.
(A long after-idling may not be allowed depending on the area, facility, local regulation, etc.)

In October 1973, two talented and spirited young engineers had a vision; to design and build high performance engines and components that major OE manufacturers could not or would not produce.

Led by Hiroyuki Hasegawa, a former engineer for Yamaha Motor Company, and his partner Goichi Kitagawa, the two secured a capital infusion from Sigma Automotive Co., Ltd. (hence the name “HKS ”), and began tuning gasoline powered engines in a dairy-farming shed at the foot of Mount Fuji in Japan. A year later, Mr. Hasegawa designed and built the first aftermarket turbocharger for passenger cars and has never looked back.

HKS pioneered the Japanese aftermarket performance industry by delivering a host of exciting new products, including the first commercially available electronic turbo timer and boost controller. Other early products included piggy-back fuel computers and sophisticated fuel management tools. Clearly HKS was Driving Performance trends for Japanese vehicles.
