Poll: What gauges to have on a Boosted car.

v10kingsnake · October 10th, 2007, 02:19 PM

The voter can choose more than 1 option if they believe it necessary.

The boost gauge is a given.

v10kingsnake · October 10th, 2007, 02:30 PM

I bought the dual pod holder from 1meansnake Mike Baxter and am leaning towards Boost for sure and fuel pressure over the A/F gauge since I am pretty sure the AEM will log the AF for me anyway. I'm thinking that once the tune is complete, the A/F gauge should be useless with the only real thing capable of changing it into a dangerous situation would be a drop in the fuel pressure. Temp was just used in the poll to fluff it out a bit. Don't really expect to see it hit over the other choices.

That's my take too, well stated.

Logging A/F with the AEM will mean you will need to have your laptop hooked up in the car. Once the car is "set-up" and tuned, you don't just forget about your A/F and monitoring it is far from useless. You still should get a good WB and A/F gauge (like AEM, WB/gauge) for monitoring while driving. Whether it goes in your gauge pod or mounted separately is up to you.

I got a Defi boost gauge for sale if anyone's interested. It lights up orange and has the bezel that spins.

boost and af.
if you lose an injector.. a fp gauge isnt goign to tell you... but your af will take a shit on you. but if you lose fp, the af gauge will go lean... letting you know you have a problem

Saying "forget about it" wasn't the way I meant it.
The AEM is constantly monitoring the AF and during hard runs lasting several seconds at a time I am thinking if I am only choosing 2 gauges the AF is fine being monitored with a laptop, after a run. Hell, even if I had the gauge visible by the time I saw it go lean it probably would be too late, right. I suppose I could do a single steering wheel pod too but fuck, I didnt want to turn the inside of this car into a Honda .

I'd rather a a/f and egt over boost and fuel pressure

Doesn't some company have gauges that will display multiple things (not at the same time obviously but it basically logs for 30 seconds or so and can show each one at a time)?

That would be a huge pain in the ass while going down the quarter at over 140mph.

I you could only run one... fuel pressure all the way. Most run only one AF gauge and therefore wouldn't catch a whole bank if one injector went. If you are leaning on it hard enough for it to hurt something, by the time you notice on your AF gauge, you prob screwed already. More chance of fuel fluctuations than loosing an injector in my experience.

put a pressure switch for fp and oil pressure. that way.. if it drops below a point, i have it kill the spark. if you want to be really safe...

tom86zt · October 10th, 2007, 03:23 PM

Ha, well you wouldn't be trying to see them all at the time going down the 1/4. Lets face it, when going down the 1/4 most people either only do/have time to look at one gauge. So A/F for me, it means the most.
Can the AEM alarm if something is wrong, or like turn on a display light if a/f goes lean/boost high/fp low/oil pressure low/ etc? That would be really nice.

Since you already have an AEM I would get the AEM "Serial Datastream Gauge" and skip the A pillar mess. The aem gauge is black and doesn't match anything so I would put it in the single steering wheel pod. You can have the aem gauge pop up the display for the output that is currently having issue, low fuel pressure, etc, it will pop up and show you the pressure. Really though if your having issues your gona be logging, and in my mind having the other gauges is not really helpful 98% of the time. If you really like the A-pillar look, add those too. With an AEM already on the car the serial datastream is just too cool not to have.

P.S. Think about changing the battery gauge for an oil temp. I haven't got around to it yet, but thats pretty useful daily for knowing your true hauling ass temp.

(from AEMpower.com)
AEM - Serial Datastream Gauge
read 19 channels simultaneously to provide reference for all outputs, including boost, AFR, EGT, H2O, IAT, knock, volts, RPM, vehicle speed, and more! Since it can read all channels at once, AEM’s Serial Gauge eliminates the need to buy a cluster of gauges, or you can link multiple Serial Gauges together to monitor additional channels or to divide your readouts across a few gauges.

thats fucking brilliant. what parts did you use?

v10kingsnake · October 10th, 2007, 03:40 PM

people been doing stuff like that with nitrous for years. Had fuel pressure switch on my GTS that ran juice awhile back. Thanks

If the car is going to be supercharged then a boost gauge is almost useless as the boost is constant at all speeds. In this case AF gauge and Oil or Fuel Pressure gauges.

If its for a turbo car then AF gauge and Boost gauge, i would add an oil pressure gauge too.

I have the single MBX gauge pod and originally had a boost gauge in there and to me it was useless. I have since replaced it with the innovative LC-1 AFR setup.

Boost will not remain exactly the same at all speeds. It will also make more boost in colder temps than warmer ones. I know from my 2003 cobra I had which had lots of work done to it. Made 2psi more easy in the colder weather. It is also a valuble tool to help see belt slip if you know what psi you should be seeing.

let me look them up. its on a srt-4 not a viper...

NOS Fuel Pressure Safety Switches: NOS-15685NOS - summitracing.com

im not going to go into the wireing, because i wont be responsible. but it isnt very hard.

most people use them in nitrous so that if there fp drops below a point, it shuts down the nitrous.
