damn this thread is making me want more gauges...only got boost and wideband...but im thinking get 2 more just for the hell of it...

 

IAT = Intake Air Temperature
- It's not really needed, but you would know if your IAT were extremely high and to let you know to take it easy.

Boost
- Easy to tell if you have a belt slipping/under boost or if you have an over boost situation. Good gauge to have for preventive reasons.

Fuel
- Low fuel pressure = lean conditions and can be sudden death to a supercharged or turbo motor. This is a must have gauge to easily detect fuel system failure and protect your investment.

Air/Fuel ratio aka wideband
- Yet another gauge for preventive care. This will allow you to detect lean or rich conditions quickly. In turn, you can diagnosis the problem before it kills your engine.

Hope that helps.

 

if you want to get technical...blowers dont really need a boost gauge...boost will be constant...only thing you MIGHT really need is a wideband...if you got an issue with tuning...nothings going to stop the motor from going if youre WOT...fuel pressure is good but i think the wideband is more worth it...plus most have a warning feature...which is pointless unless you can get off the gas within a split second...

i just think gauges just look cool as hell...chicks dig pretty moving lights...

 

So what happens if you're not producing max boost because of belt slip or if you're overboosting...? A boost gauge is definitely a necessity on a car with FI.

My buddies car was saved because of one. He put on a new (supposedly) 10lb pulley and when he took the car out for a test run he hit 12psi... turns out the retailer sent him the wrong pulley. He would have blown his motor real easily had he not been watching the boost gauge.

 

Yeah, I have Boost and IAT but want to get the SOS pillar pod and get two Aeroforce gauges so I can monitor all sorts of fun stuff... :-)

 

haha yea gauges are fun...

well if the car is not tuned then perhaps it can help...but FI i would definitely pay to have it tuned...

 

I talked to a guy at a good performance shop down here. He said that a fuel pressure gauge isn't very necessary, because if you have a wideband A/F gauge you will know when you're running lean right away. A fuel pressure gauge is like double security...
