Do you think this psi gauge will melt in this location?

[DROPthatCLUTCH]

Wondering what you think. I absolutely live the spot I have got it in, but am worried about how it'll react to the heat from the manifold.

I have another line I can run the gauge to another spot if need be but I'm a little worried about accuracy if I add another 2 foot line coming off that. Opinions are appreciated!

The pressure at that port is essentially static. You should run a line off of that location and put it somewhere else where you can isolate that gauge from engine vibrations. It's less the issue of it melting and more the issue of it cracking from vibrating and heat cycling. Boost gauges have more than 3 feet of line and they are still very accurate, so you'll be fine with 2 feet of line. If you don't believe me you can prove this to yourself by running it like that on a dyno, then trying it again with the 2 feet of line.

Are you leaving it there permanently or just to see what oil psi your turbos is receiving at idle?

Okay great to know! That spot is just so sexy, but that is very true about vibration. I'll move that take-off port down to the OFH after the restrictor, run the line up and zip tie it somewhere in the bay.

Permanently.

Permanently.

Why? Do you have an oil pressure gauge at the OFH also?

 

[Leonthefaded]

Dude... how much heat can that gauge withstand... cause I see that B exploding imo

Don't see a point for monitoring the oil pressure at the turbo. Not like you can see it when doing a pull anyhow.

Adding some line won't effect accuracy, I've got 2-3ft of line coming off my OFH to feed my Oil pressure and temp senders, never been an issue.

Why wouldn't you want to track oil feed pressure? It's a must for any modified motor or turbo combination. Every motor is different, and every turbo has specific requirements from the manufacturer.

This however I agree with, I measure oil pressure in multiple spots. But I use sending units as I don't feel like having high pressure +200*F oil all over me if something fails.

You can dead-head the gauge out on a separate line plumbed in where you have the gauge currently.

Yeah, what I'm going to do actually is put the take-off port down at the OFH just after my restrictor and run the gauge up somewhere else with my spare -4an line. Thanks everyone!

 

[T is for TURBO]

I would not run it there, or permanently

The way I have mine set up is I have two short #4 AN lines. In between the two lines I run an FP line filter with a #4 AN male to female fitting with a 1/8 NPT test port machined into the middle of the fitting. I'll see if I can find some pictures.

When I want to check my turbo oil pressure, I unhook my sending unit from my OFH and hook it up to the feed line adapter. Normally my sending unit is attached to the OFH.

Once you know what your pressure is at the turbo, all you have to do is monitor the OFH pressure and you should be fine.

**Pictures added**
Not the best photos, but you can see how I have it set up off the OFH. The blue fitting has the test port on it and will be moved to the opposite side if the inline filter at some point so I can see what kind of drop in pressure I will see from the reducer built into the filter. (There is also an #4 male to male AN fitting between the test port fitting and the filter.)
