Why a boost guage

[NSperduto]

I've been reseaching putting guages in my truck and I'm thinking of just trans temp and Pyro. I know the reason for those.

But my question is I see people putting in a boost guage.



Why do you want to monitor that? Or is it just a nice to have.



I know you monitor pyro and trans so you don't overheat them, but why the boost guage.



Then there's also people putting in a fuel pressure guage. Not sure if I really need that though.



Thanks,

Nick

Its another way to keep an eye on the truck...



Say you had Higher then normal pyro temps and you see lower boost pressures, that would make you look for a boost leak somewhere in the system. Just another way to monitor the trucks/engines performance.





Plus it looks cooler with more gauges Oo.

I agree

Boost gauges are just fun. You don't have to get a real expensive one. You can hook up something temporary.

There fun for bragging rights.

You can establish a base line norm for you drving style.

Helpls keep you awake on long trips ( something to look at)



Best of all when that Ford or chevy pulls up next to you on a hill you can judge how much you got left to blow there doors off. Gear ratio's and different things can give you the advantage or disadvantage. Just nice to know wether you want to put the hammer down or just hold.



For sensible reason like pulling a load on a hill in traffic I can judge better how much room I need to pass a 18 wheeler or just sit tight.



Can't ever have to much info. Especially with your new quiet ones. Ya don't have that prob in my old 1st gen with banks.

OK! So here's one more for you to cogitate.

I have a dash-mount 3-gauge setup with the standard boost, pyro, and one more. I also have another pressure gauge plumbed to the pre-turbo exhause. Crazy?

Well, I can watch it snap to 50 lbs. when the brake comes on at 2500 RPM. Better yet, I can tell if the brake is on when the stereo is too loud!

I put this setup on my old '96 and really liked it. Now on my 04. 5 I think it is going to have value. I am at about 10. 5K miles now and think I'm having a problem. Most of the time I am getting about 15 MPG (after the TSB). In this conditiion my exhaust pressure is generally two to three lbs. higher than my boost.

Occasionally, something happens and I see the boost run about the same amount higher than the exhaust. During that time I am getin 17. 5 MPG or more and significantly more response.

My current unknown is; am I having turbo problems or what???

NEVER TOO MANY GAUGES!!!

Boost gauges can also alert you to fuel delivery problems, indicate overall loading on the truck, and if you bomb it'll let you know when you're pushing that tiny stock charger too hard. If you don't tow heavy I would even say it is more important than a trans temp gauge.
