Gauges

We all want to change the world. But when you talk about destruction, don’t you know that you can count me out. Don’t you know it’s gonna be alright?

How Many & What Type?

First off i can tell you forget trying to read your gauges on the fly. A 20 second run at 18 mph your only concern is keeping it out of the soft patches and between the lines. I am on my third set of gauge trying needle and bright digital to no avail.

Now I have switch to gauges that have recall. At the end of your run you can  recall your time stamped peaks and as a added bonus you can also set alarm levels that will flash when exceeded. The alternative that a few of our richer competitors are running is data acquisition system. These are of course great because you can plug in your laptop and get all the real time info displayed in a chart.

Dual Boost Gauges

The idea for running two boost gauges is to measure drive pressure and boost pressure . This will give you a pretty good idea if your turbo is well suited to your engine setup.

Ideally drive pressure should be a little higher than boost but very high drive pressure is hard on turbo shaft and not efficient . Anyway a short explanation why two pressure gauges.

Exhaust Gas Temp (EGT)

So one important thing to keep in mind is your egt probe must be a fast reacting type. I run a 250 mil a second probe. A good way to tell what type you are looking at is the probe tip. How hot is safe? that is the million dollar question that will all depend on your setup. If your around 1450 F you should be ok but some guys run hotter.

Water Temperature

Plenty of spots to thread in a temp sensor on most engines. Keep it under 210 F by end of run you should be ok.

Tach

I ran across a neat unit that will allow you to run any tach it basically uses a magnetic pickup off your front pulley then converts the single to what ever type of tach you have. Its about 80 bucks on ebay will save you buying a pricey diesel tach.

My Recommended Gauges

I am going to revise this statement after a year of running these gauges. I have found they are difficult to setup and don’t like the vibrations. I am still using them for now but might look for alternatives  

I use Auber gauges great value for the money and have great features. You have peek time stamped recall, also adjustable alarm that can activate a light or buzzer. Another cool feature is it can be set to active a 12v device at a given temp let say like another water injection nozzle. The one model gauge will do 5 different readings so just buy three of this gauge and set them each for different function.

Data Acquisition System

I don’t know a lot about them but the charts are great. You can see egt and boost in relation to each other very good for dialing things in.

Wiring

Summit sells a nice switch panel that will make your wiring a lot simpler. Fuses are build in for each switch and light shows switch is active. The wiring and switches are heavy enough to skip using relays. I find keeping it simple is best. 

So main power switch would power the complete panel. I like to run water pump and fan on one switch.

The fuel pump on one and water injection on another. You should change out one switch for a momentary for glow plugs not good idea to use regular switch.

A few switches left over for flux capacitor and other secret devices.
