Sure the front apex was ****?, it is just the second to last Pic is of the rear Rotor Housing and e-shaft.

Damn rats nest in the engine!

But really, that's an apex seal that took a **** like that?!

it seems that foreign substance like rocks went into the engine and **** everything up. Look at those marks on the rotor !

More infos on the engine?
Boosted with a tuning issue perhaps?

Yes, but the guards at the Renesis prison are not very easily persuaded to allow outside travel resulting in the troublesome inmates causing much uprising and unrest.

You can usually bribe them with a big shot of nitrous.

No, I'm not sure, that's just what he said. The engine was not boosted. Although he did sell a nitrous kit, I don't think he ever had it installed.

disoriented apex seal fragments under the influence of laughing gas and having a one fragment party inside a rapidly spinning party room.
Sort of like that thing that bounced out of control in the movie "Men in Black".

Under normal conditions only the amber numbers will be showing. I just don't like the look of bunch of different round gauges.

Look at the PLX Devices OLED guages...You can have 4 sensors on each display..

I have 3...and can run up to 12 different sensors So far I can only figure I need the 9 I have

I checked those out and they are very sweet. But really I just want oil pressure and oil temp, everything else I get through the Scangauge II. But maybe I will have price out everything i would need to get the PLX, it would be nice to only have one gauge.

180 to 200 is the usual oil temperatures for the RX-8 right?

I would say average under normal conditions.

I like it mate....I think it looks KOOL... do you have a website link?..

It does have more than one function? OP , OT, no more?

Personally (no offense guys) I hate all the add on guages over the dash, although the function is there it looks way too RICE..

I like this if it is an all in-one, I may even consider for my 8 and be one of the first to get S2 the OP and OT numbers..

I would like to see Mazda move into a small multi-screen LCD readout similar to the GTR...perhaps the new RX-??

Found it on ebay...


Automobile Multimeter for EGT, Boost and More..

This digital automobile gauge can be used to measure temperature, pressure and other important parameters such as battery voltage, current and air/fuel ratio. Its bright LED display is easy to read from a distance as compared with many dim LCD type digital gauges. The programmable alarm will turn on a blue LED in the front panel to get driver's attention if the temperature/pressure is above the setting point. It will also close a relay output port that can be used to turn on a buzzard, shut off the fuel, or turn on a cooling fan. The meter stores the peak temperature/pressure with time that can be checked later. It can also operate in the peak holding mode so that only the maximum value is displayed. The brightness of LED display can be synchronized with headlight. When the headlight is turned on in the night, the display will be dimmed by the illumination signal. It can also be dimmed directly from the key pad. Developed based on industrial grade instruments, this four digits gauge offers up to 10 times the resolution and accuracy than the most of 3 digits gauges on the market. Its compact size (24 x 48 mm or 1x2") takes less space than a 52 mm round gauge.

For EGT measurement, the meter will work with all EGT sensors on the market, grounded or ungrounded. There is no input impendence matching requirement. It can display the temperature in either Celsius or Fahrenheit. It is probably one of the most accurate exhaust gas temperature (EGT) monitor on the market.

For boost pressure measurement, the meter will work with all MAP sensors as long as its pressure/output voltage relationship is known. It can display the pressure in either Bar, PSI, or user defined units with high resolution. However, it will not display the pressure with two different type of units in one scale such as PSI for pressure range but inHg for vacuum range.

For water/oil temperature measurement, the meter can display from -199 C to 250 C (or -199F to 500F) with 1 degree accuracy when used with our RTD sensor. It will also work with our liquid tight thermocouple based sensor, In addition, it can work with VDO 150C (300F) sensor with a limited display range (50-150C /120-300F).

For water/oil pressure measurement, the meter can work with either old style resistive pressure sensor or the modern style pressure transducer with linear voltage output. The meter offers a regulated 5V DC output for the power supply of the pressure transducer.

For air/fuel ratio measurement, it can be used to display either air/fuel ratio or lambda when interfaced with Innovate Motorsports' LC-1 wideband oxygen sensor controller. Please note, the meter cannot work as a stand along AFR with the oxygen sensor unless you are using a controller.

I'll let you all in on a little secret... I'm starting work on a device that interfaces with several of the most common types of sensors, and can be viewed on any screen with a composite or VGA input (in dash DVD players, dash/visor mount LCDs) all at the same time. Although I don't suggest you hold your breath as it is still about 6 to 8 months away from a low-volume production run.

that is normal.

but it also depends on your engine load.

if you're cruising on a highway, your oil temp will be much lower.

if you carry a lot of weight, it will go higher.

depends. ya know

my oil temp range from 70-110 Celsius.

Last night I was cruising on 495 and my oil temp was around 75-85 Celsius. About 50 Degrees outside.

Three? Where the hell did you mount all the modules?

I have one DM200 OBDII hooked up right now(so I monitor 4) to my vent pod.
Because I am lazy and waiting for Winter, I haven't daisy chained the sensor module for oil temp/pressure yet.

I have the vent pod as well and a oil temp gauge but I agree with ASH in terms of the look and the fact that it draws attention. This gauge is small and I have some ideas for installation due to it's small footprint. You can also order the sending units if different lengths/types, etc.

Here is the place that makes them.
