High turbo noise

On my 2014 Ram 3500 the only gauge in my instrument "cluster" that has anything to with the turbo is a boost pressure gauge. Nothing at all that shows turbo RPM. I am scratching my head as to where this 20,000rpm figure came from.

I think I heard something like that on one of the TFL road tests. They had the Ram loaded up & went charging up the hill. Cant remember which one it was though , the guys on board were wondering what it was too.

20k is just looking at the turbo gauge on my instrument panel. It shows the rpms as they rise and fall, certainly not the same as my Silver Leaf I was used to with my 370 ISL. Perhaps it was the fan as well. Just an unusual noise to me but not alarming. I figured there are lots of folks here who are way more familiar with this rig than me.

Thx

we really need to know what the 20,000 stands in relation to. Maybe you forgot an extra zero? Were you looking at boost with the metric setting (Showing Kilo pascals), 200,000 kpascals is equivalent to 29psi which is about right.

The options are 15 & 20 psi on a boost gauge - no problem. Or 1500 & 2000 degrees on a EGT (pyro) gauge - problem.

Are you sure the noise you heard wasn't the radiator fan clutch ?

When those things lock up (at high temps and high RPMs) it almost sounds like a jet engine is under the hood.

I'm wondering the same thing.

20,000 what?

What are you measuring and how are you measuring it with? :h
