hi all,

Thinking to install the Defi gauge in my 8 and I have done some research in the forum and the recommendation or sort of standard are Oil Press, Oil Temp, and Water Temp. also additional parts such as adaptor, main control unit.

Just want to check who had installed these gauges useful or not and I know the OME doesn't give you a good reading feel ... it simply HOT AND COLD are behave pretty much the same from my point. Likely I will install on the dash board any problem in term of heat or outside temperature cause any problem to the gauage ...

Apart from that any recommend workshop that can deliver a good workmanship and cost as well ... someone mention about the new MG Garage maybe I get quote from them later.

Any feedback are welcome ?

Thanks

 

It's definitely good ! I have a total of six Defi Gauges on my dash !
The reading are pretty accurate and I am sure you will love it.
(Do a search and you might get to the see a pic of it, if not I try to upload one later in the evening )

 

Coming Soon: From Racing Beat, a 3-gauge panel cluster pod! Mounting directly under the ventilation controls, this gauge cluster allows the installation of three 2 1/16" OD gauges. (Available early 2006)

 

watoke - 6 guages are just over kill. Even if you had a turbo in your car , which i serious doubt, No one really needs 6 guages. It is just ricer mentality to me.
ps; what no battery voltage guage ? :P :P

tata - The guages you need most , would be Water temp, Oil temp and oil pressure. Roughly in that order. You could get the defi display that would read both water and oil temps so what you need only one gauge. May be you could get the mazdaspeed dash mount. It has holes for 3 58/60mm gauges.

 

Slick8 - sorry man, we drive on the correct side of the road on this half of the planet :D

 

I only think that the defi gauge like Water temp, Oil temp and oil pressure only got use when u got turbo.Don't think NA needed wow.Unless like what mr.brown said zhgn ur car and ppls will scared

 

You will be surprised that maybe some people got turbo, just never say only.

Boost gauge works like intake manifold pressure anyway so can still be useful.

Fuel pressure is good for tuning.

So this makes five already including water, oil temp and oil pressure.

And not forgeting the oil pressure gauge is the single most important mod you can do, at least you have warning when the oil is too low instead on relying on the "idiot on/off" built in gauge.

 

Well, u probably felt "dun need" as most pple will feel the same way, which in a way or another I do agree, but till something happend, then u probably will say " Zha Chai" , if i got the guage and ample warning would have given me to avoid so much more $$ to repair

Volt Gauge? Yeah, I got a capacitor which will show me my battery voltage before and after starting the car (well i replace the battery every year, be it working or bad)

Anyway, rx8 is not my first performance car . hehehe....

 

Yoz bro emperor, me no turbo leh .... normal NA still ... heehee
But in the pipeline and plan to do it ......

 

to the turbo god!

 

watoke - Not that i don't feel a need, Just that that is too many. For any rotary engine, water temp; oil temp and oil pressure guages are very important. As rotary engines running hotter than most engines. Even mazdaspeed agrees cause if you buy their triple guage dash with defi guages, those are the guages you get.

Intake pressure/vaccum guage - would be good to see what kinda hg your engine is pulling at idle or with load to test how "healthy" your engine is. But if your engine really were to go, i doubt that guage were to help as you would be able to see and feel the difference.

Exhaust Temp Guage - There is a that you might or might not need. A good exhaust guage can help with your tuning along with a Wideband O2 sensor to correctly adjust your fuel and ignition. There are some thread about it on rx7forum.com. But the thing is that would only be for more higher tuned cars.

will not comment on your pressure guage :P ..hehe.. Still that is a lot of extra guages ..haha.. As for your turbo kit, Mm...i just hope it is not from greddy ..haha..


yohji - not true , NA cars even ours can benefit from having these three guages. To make sure even thing is running within operational limits.

 

I saw quite a few wrx with 7 or more gauges. Abit cluttered.

Most classic is a s15 that driven by a girl or lonh haired guy that has 6 pillars on both a pillars and quite a few more gauges on the centre.

 

Of course i know our car need some defi gauge but 6-7 is too many liao.Anyway,u guys really got see the gauge while driving or.....

 

Due to the popular demand ... I have Order and Install, another happy customer.

Someguy_Sg: Do you have any recommend setting for "Warn setting" for these gauges ... I have installed (Oil Temp, Oil Press and Water Temp).

Due to our unique weather in Singapore ... I cannot rely on US or other countries ... but I have the following setting

Warn setting
Oil Temp: 120
Oil Press: ?? Need help (making buzzer noise when Idling and I know it's normal)
Water Temp: 100

Again any suggestions are welcome.

 

My max is:

Oil temp at 100
Water temp at 100
Oil press between 2 to 5

I think it buzz when its too low. Maybe should check oil level first.

 

That was fast ... wish you are in customer service sure will get good raise.

I also agree setting oil temp around 100 ... but if oil press set between 2 - 5. I am sure will get the buzzer ... currently I set at 2 at the moment and already giving buzzer signal while the car is idling ... again I will monitor the setting from time to time ...

Thanks

 

What the hell is you guys doin' at 6 in the morning ..haha..

 

I am in sales. Too bad no one will give me a raise....

 

100*C for the water temp seems a bit high for me. A better limit would be 84-90*C

 

Actually the perfect temperature where the engine puts out most power is 92 degrees. Sometimes low is not neccessary better.

 

I know tuning for power can be done from EGT, but I never knew can use water temp for power tuning siah... so chun at 92 deg somemore. Emp... are u pulling my leg? I know I'm not very tall lah. Pls enlighten me how you arrive at this answer leh.

 

Bro... I never give false info one. I remembered it was 92 from my research some time back. What i can find now that supports my claim is found in the link below.

This is 1 small reason why its good in the long term to warm up the car before moving off.

http://auto.howstuffworks.com/cooling-system1.htm

"The engine runs best when its coolant is about 200 degrees Fahrenheit (93 degrees Celsius)."

* The combustion chamber is hot enough to completely vaporize the fuel, providing better combustion and reducing emissions.
* The oil used to lubricate the engine has a lower viscosity (it is thinner), so the engine parts move more freely and the engine wastes less power moving its own components around.
* Metal parts wear less.

I do not pull legs and on the contary i am getting shorter from reading and researching too much.

 

The thing I find hard to believe is a specific water temperature to indicate max power for every engine configuration especially since our engines aren't the typical 4/6/8-cyl inline/v/h.o. internal combustion types. Even when we use EGT for tuning, it's not relative to a specific temperature, but relative to peak EGT so it's quite strange that water temperature can indicate max engine power. Max cooling efficiency I can still believe, but not for engine performance.

Anyway, the only thing I saw in the article about engine performance is "The engine runs best when its coolant is about 200 degrees Fahrenheit (93 degrees Celsius)". It makes no reference that "best" = max power.

 

The max power part, i read somewhere sometime back. It somewhat like why fuel burns best at 14.7 a/f ratio no matter what engine you run.

And the figure i remembered was 92 degrees and the "howstuffworks" article is the closes i can find to justifying my claim.

Even if people are not concerned about max power, the article in itself is useful for people who wants their car to perform better, and longer.

 

Emperor - hehe...14.7 AF ratio or Stoichiometric Ratio is not the best. It is just that at 14.7 there is more air than fuel so there is a more complete combustion with little or no hydroncarbon left. Resulting in in a less polluting exhaust gas. If you read the articule from motec concerning the renesis engine, they found that it like a AF ratio of 13.5-13.6 or 0.92-.93 is the best over all.
