You could always add a switch and use your trans temp with an additonal sender to monitor differential temp. But, since you have two differentials, you could add a new gauge and a switch to monitor both front and rear. Or, add an oil pressure guage. They also have clocks.
A Hobbs meter would be real cool. I just wished I had put one on when I got my truck.
It sure would be great to have a full complement of gauges like my uncle's Macks always had.

100 psi is plenty for oil pressure.
What pgilles meant by drive pressure is the pressure inside the exhaust manifold. A 100 psi gauge will be OK for that as well, but you will need to run copper line off the manifold, coil up a couple feet of it to isolate the nylon tubing from the heat. You'll also want to put a needle valve in line to steady out the readings.
I'd rather have the oil pressure gauge.

What should I get for my 5th gauge? I've got Fuel Pressure, Boost, EGT, and transmission temperature. I was thinking oil pressure next. Does ISSPRO make an oil pressure gauge? My goal with this truck is 600 rwhp daily driven so what do yall think would be the best gauge to get? Thanks for the help yall.

Oil Pressure is good.....but drive pressure (TIP) gauge would be awesome...especially useful as you add power...get a reading on each change. To have ongoing comparison between EGT's and TIP would be very educational, IMO. Would also need an inline filter to keep gauge clean.
I have Oil Temp & Differential Temp gauges (on Dash Pod w/ FP) and, while useful, they a amazingly stable and boring on the CTD. The differential probe mounts in the roof of the cover and only registers a reading while cruising (due to needed splash) and after fluid warms up!

I use a intake air temp gauge for a fifth. Interesting gauge, it moves, was using the sender for oil temp, boring about the same as the coolant temp.
Just tap a port in the air horn for the sender. You will need a gauge that reads down to zero.

Any data on how much it climbs when pushing the turbo at its upper limit...as you pass the top of the MAP for your HX-35(?). Say above 30 or 32 psi?m Does rate of climb get dramatic at this point...as one might expect?
I've seen your posts comparing under hood temps with OAT...but I don't remember seeing anything about this?

RJ, optimum intake air temp is 50-90°F. Most often the IAT is always 20° higher than the outside temp.
I rarely see it exceed this range except when:
1) It's below 30° or above 90° outside
2) boost exceeds 40 psi, then it can get up into the 200° + above anbient range. 30-40 psi boost raises the IAT to around 100° above ambient. Below 30 psi boost and the 20° above ambient rule holds true. The intercooler works excellent when the boost is under about 35 psi, I've seen drops of over 250° from the inlet to outlet.
3) idling stopped with the A/C on in hot weather can cause the temps to exceed the outside temp by over 100°

Great info...about what I would expect but more dramatic (double) at high turbo rpm.
This would make a great 6th gauge!
Sorry to sidetrack the thread.
