The number one cause of turbo failure is oil "coking". Oil "coking" occurs when a turbocharger is not properly cooled down and the oil that normally lubricates the center cartridge heats up and forms solidified oil deposits. A turbo timer allows an engine to idle for a preset 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. In 1982 HKS was the first company to offer a commercially available turbo timer, and has since been the leader in turbo timer technology.The HKS Turbo Timer Type-0 is a basic turbo timer that features an auto mode that adjusts engine idle time according to the most recent driving pattern, multiple preset times, audible alarms and a volt meter. The easy to read back-lit digital LCD display flashes between orange and red during the countdown The Type-0 is ultra compact, less then a 1/4 din in size and available in a black or silver case.
