Default Are aftermarket gauges on N/A car Important?

I was just wondering what everybody thought about after market gauges on a N/A car. I was seriously considering getting some gauges for my car. I'm not sure if I'll ever go turbo but I am doing some pretty extensive N/A mods. I currently have a Cobb/PRM CAI, I should be getting my Brullen headers, high-flow cat, and catback installed within the next few weeks. I'll probably get cams eventually and will probably also need some sort of upgraded fuel delivery. I thought that Fuel Pressue, A/F, and maybe EGT might not be a bad idea.

Do you think gauges are important or is that just a turbo thing...

Oil Pressure, Water temp, EGT's... A/F wouldn't hurt, but with an S/AFC you can always do the blue wire mod and save yourself some cash.

Oh, and Turbo or not gauges are always a good idea, ask a 9 second mustang owner if he thinks gauges are useful

Well, if you're thinking about controlling fuel ratio, then EGT is a must have (or at least an A/F meter). Maybe a fuel pressure gauge, too.

Besides that, oil pressure is a nice gauge to know if your engine is losing pressure or not. Vacuum/Boost gauge tells you how healthy your engine is.

Depending on what the intended usage of the car is, I agree with Korey. If you're doing extensive mods and intend to whip the car pretty hard (ie 30min sessions at open track events) then gauges would probably be a wise investment. Oil pressure, oil temperature, and water temperature are always good to have, and maybe fuel pressure and EGT. Those last two would depend on how serious your modifications get.

Oh, and the above gauges (minus EGT) are what I'll be running on my soon-to-be-naturally-aspirated-again street/auto-x/open track Mustang.

I'm running A/F, Oil Temp, and Oil Pressure. Although I know that the stock temp gauge and a water temp gauge are different, I trust in the stock gauge to warn me of that... or the oil temp gauge. I don't see a need for EGT gauge unless you've got a tech II and some serious engine work... If you've got a turbo I understand.

I just ordered a Lotek A-pillar triple gauge pod for the install. I'm not sure if I'll like the gauges on the A-pillar but since the pod is half the price of any dash pod I figure that I'll give it a try. I'll do my best to document the install when I get everything together.

I should be getting the 0-100 psi fuel pressure gauge not the 0-15 psi one right???

Default S/AFC

Just curious...

I am finnaly to the point of getting a full catback exhaust, and cams... along with a fuel pressure riser.

With S/AFC i understand i can control fuel pressure?

Is it hard to configure? will it work with J/C torque chip?

Nor sure, but I don't think you can control fuel pressure with the S-AFC, you might need a Rising Rate Fuel Pressure Regulator for that. Some of the people that make these are Cartech and Bell.

I'm having my probe put in for my EGT gauge tommorrow afternoon. I'm paying $75, which I think is a pretty good price. I'm still NA, but this is an important gauge if you plan on going turbo or messing with your A/F ratios. Also, I'm putting in a Fuel Pressure Gauge, you can see that all this is in preparation for a turbo. Anyway, just lettin you know whats I think.

Keep it Sticky

It doesn't measure anything 'exactly'. More like it 'roughly' measures the temp. I heard it isn't very accurate. And where does subaru get off not even giving the outback a voltmeter?!? How will I be able to see a bad alternator coming? When my sonoma started acting up, I had a few days to keep an eye on it and prepare to replace it and/or the battery. Without one I'll know when the igntion goes 'click, click, click'... I would also like all the gauges that most cars have, like oil pressure, etc...

Coolant Temp is very important. you don't want to drive your car if it's overheating. It's a good indicator to see if you have a leaky cooling system or dead head gasket.

The stock temp gauge is very inaccurate. It's more like a cold-normal-hot gauge. If cold, it stays at the bottom. If at normal tempereature (doesn't matter what temperature it's operating at), it points at middle. If too hot, then the needle goes to the top.

Default Exhaust Gas Temperature

It tells you if your engine is burning up due to lean mix. Anyone have experience with a 2.5 SOHC with Cobb street cams and exhaust gas temps? I'm hoping the MAP can handle them but considering a EGT too.
