The REV Shift Timer was developed specifically to combat improper engine oil cooling and over-revving. The RST is a full functioning turbo timer with an integrated shift light, plus additional monitoring functions. All these features are built into the same compact size unit as ARK Design's Advanced Boost Controller (ABC) so the REV Shift Timer and ABC perfectly complement each other in any vehicle's interior.

The RST's auto time function automatically calculates how long a turbocharged vehicle's engine should run after the ignition has been shut off to prevent oil coking. By allowing a turbocharged engine to run at idle, engine oil is circulated through the turbocharger, effectively cooling the oil. If the oil is not allowed to circulate, the oil will sit inside the turbocharger and can solidify into small crystals (a process known as oil coking) which, over time, can damage turbocharger seals and reduce performance or even destroy your turbocharger's oil cooling system.

Over-revving any engine can lead to disastrous results, but with a turbocharged engine the risk is even greater due to the additional air being forced into the combustion chamber. The integrated shift light in ARK Design's RST allows driver to know precisely when to shift to avoid over-revving. The RST's shift light is a bright white LED that can't be missed when in a driver's line of sight.
