I just installed some gauges, i put the fuel pressure gauge on the bottom of the fuel filter. Then I put the Trans temp gauge on the hot line to the trans cooler.
I will install a boost gauge when the correct bolt come in. Also have a EGT gauge to install when I get the time to drill it.

What ranges should these gauges should be reading?

Thanks for your help.

 

Fuel pressure idk I have a Rail Pressure gauge Mine is not hooked up in the same spot as yours
transmission temp is going to be lower then mine I normally run 140+. My trans temp sensor is mounted in the line and takes the temp of the fluid not the outside of he line... I bought a fitting and made it work..
Boost the if you have stock turbo you should see 32 psi floored
24-26 psi normal driving... lower when at 65 mph see below
EGT varies at 65 mph I am at 500-600 degrees F with boost in the single digits.. empty
unless i go up a small hill or a incline then everything goes up its kinda normal
Max EGT is 1350 or less... Cummins says that they have tested our common rails at 1450 degrees... I am not recommending you run your EGT that high.. 1350 or less and 1350 for a few seconds...
Do yo have any programmers or anything on the truck?

 

we have to have Pictures of the gauges

 

Thanks for the info.
My truck is mostly stock, just a cold air intake and muffler delete. I am installing gauges now so when i install a programmer this spring I have them and a baseline of my truck.

Will post pic when i get all gauges working, need to get the last bolt for boost gauge.

 

oh you have one of those... I didn't go that route I drilled & tapped my intake horn...

Your EGT's maybe a little lower with the cold air intake not very much.. When you get the boost hooked up Please post your boost numbers I really want to know what they are..... Thanks hope that helps Pizzo

 

I will post my boost numbers when I can. Do you think the boost numbers will be significantly different between the 2?

 

I am not sure, but that is what the cold air intake is supposed to do... If your boosting properly...

 

You're not going to see a significant difference in boost pressures with the intake vs a stock intake.

What you will notice is slightly quicker spool times and "slightly" lower EGT's.

Remember, boost is a measure of restriction not flow. Higher boost doesn't always mean more flow.

The true measure that indicates performance is lbs/min of air.

50 lbs/min at 26 psi vs. 90 lbs/min at 26 psi is a HUGE difference.

Think of it like this (I have to credit Nickbeek with this one).....

If you're filling a swimming pool, do you want to use a 5/8" garden hose at residential pressure or a 3" firehose?.....
