Rev-Shift Timer

Keep your engine Cool and Calm.

REV-Shift Timer does it all for you.

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.

Battery Voltage Display

Battery voltage can be displayed on the

LED display, along with battery change
status

Red LED screen

Rev-Shift Function

The engine's speed (RPM) can be captured through either the alternator pulse or directly from the ECU. The shift light can be set to turn on and off at any RPM. For indicator purposes, the LED will flash in bright white when the user preset shift point is reached.

Timer Function

Auto Mode calculates (by driving style) how long a turbocharged vehicle's engine should run after the ignition has been shut off. Manual mode allows the driver to set the desired idle time manually.

A/F Ratio Display

A/F ratio can be displayed numerically on the LED display and in color ranges by the LED indicator. A/F ratio is calculated from the factory O2 sensor. Because most OEM O2 sensors are designed for emissions, the RST readings may vary compared to a wide-band A/F meter.
* A/F ratio readings will only work with Zirconia type O2 sensors.

Keep your eye on the prize, not your gauge.

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. The A/F ratio is displayed in a numerical value on the LCD, and also as different colors on the LED indicator.

    • Hi guys, has anyone either purchased or built themselves a rotisserie for their car before? I can only just justify the need for one hence why I should just make one but at the same time, if I make one I can kiss another 4 weeks of potentially productive car working time goodbye because I'm building a bloody rotisserie....  I mainly want it for the application of the body deadener.  Cleaning the old stuff off, priming and then colour over the deadener doesn't worry me, it's just the application using the Schutz Gun that I feel would achieve a significantly better finish painting it side on and keeping the Schutz Gun upright.  I don't think they would work well on the side let alone almost upside down for some areas.  If the product I use (Terosun, etc) could work through a HVLP ok then it might be ok to apply without the rotisserie.   I can get one of these style ones for about $1200 which is pretty good value-     I reckon if I made one it would cost around $500 but it's more the time that it would take is more of a killer than the cost.  They look to hold their value pretty well second hand so I could always sell it after using it and realistically only lose $200-$300 at worst.  Or keep it and buy another project when this one finally sees the light of day... Anyone selling one...? Cheers!  
    • While it is a very nice idea to put card style AFMs into the charge pipe (post intercooler, obviously), the position of the AFM and the recirc valve relative to each other starts to become something that you really have to consider. The situation: The stock AFM is located upstream the turbo, and the recirc valve return is located between the AFM and the turbo inlet, aimed at the turbo inlet, so that it flows away from and not through the AFM. Thus, once metered air is not metered again, neither flowing forwards, or backwards, when vented out of the charge pipe. When you put the AFM between the turbo outlet and the TB, there is a volume of pressurised charge pipe upstream of the AFM and there is a volume of pressurised pipe downstream of the AFM. When the recirc valve opens and vents the charge pipe, air is going to flow from both ends of the charge pipe towards the recirc valve. If the recirc valve is in the stock location, then the section between it and the TB doesn't really matter here - you're not going to try to put the AFM in that piece of pipe. But the AFM will likely be somewhere between the intercooler and the recirc valve, So the entire charge pipe volume from that position (upstream of the AFM, back through the intercooler, to the turbo outlet) is going to flow through the AFM, get registered as combustion air, cause the ECU to fuel for it, but get dumped out of the recirc valve and you will end up with a typical BOV related rich spike. So ideally you want to put the AFM as close to the TB as possible (so, just upstream of the crossover pipe, assuming that the stock crossover is still in use, or, just before the TB if an FFP is being used) and locate the recirc valve at the turbo outlet. Recirc valve at the turbo outlet is the new normal for things like EFRs anyway. In the even of a recirc valve opening dumping all the air in the charge pipe, pretty much all of it is going to go backwards, from the TB to the recirc valve near the turbo outlet. But only a small portion of it (that between the TB and the AFM) will pass through the AFM, and it will pass through going backwards. The card style AFMs are somewhat more immune to reading flow that passes through them in reverse than older AFMs are, so you should absolutely minimise the rich pulse behaviour associated with the unavoidable outcome of having both a recirc valve and an AFM in the charge pipe.
    • Yep, in my case as soon as I started hearing weird noises I backed off the tension until it sounded normal again. Delicate balance between enough tension to avoid that cold start slip and too much damaging things.
    • I'm almost at a point where I feel like changing the alternator. Need to check the stuff you mentioned first though.
