It's either psi or bar 2 Link to comment Share on other sites More sharing options...

The gauge in the picture above does NOT indicate that this is the case for the specific gauge, so the only safe assumption is that the value is completely in "in/HG" on the gauge in question. (unless I'm blind, there's no mention of "psi"). You could possibly infer that they are different scales by the different increment sizes, but which scale is it?

I'm sure Marcos gtx is only pushing 9psi at 3500rpm as well.... 1 Link to comment Share on other sites More sharing options...

In saying all of that, it's says "x1000" on the revs, so the gauge is showing he did 3,581,000 revolutions per minute at one stage haha, so I doubt the overall accuracy of the "legend" on any of the displays because of this.

The live digital readout is lime green, clearly to make it distinct. Hair splitting FTL. Keith you're doing it again dude... Whatever feeling you have right now, try to use it to remind yourself to stop posting. It's not adding to the forum experience in a positive way.
