Anyone logging fuel pressure?

If so how did you go about it. I have a DEFI guage on the way and I think I should be able to do it with that and the datalogit cause it is an electric guage.

actually, I found an electric sensor that has 0-5 volts output, that is explosion proof, and is 1/8 npt connection, they are not cheap, but then again nothing is explosion proof ever is, its for gas compression duty and retails for about 210.Canadian, I may due that and just patch it into the spare a/d input on my haltech..max

Yeah, thats definetly cheaper.....They have also been discontinued, are the wrong voltage and plastic bodied, not something I want on my fuel system...I am gonna spend the extra coin on the all metal one...Max

Are you just talking about the plactic "T" under the transducer or the top part where the weatherpac connector goes Max? The thread on the transducers posted above is 1/4"npt.

I got 4 of them also Planing on loging all kinds of stuff with them. Fuel pressure, intake manifold pressure vs exhaust manifold pressure and whatever else I can think of.

That’s kind of what I was wondering??
What sensor did you get max, do you have a pic and a link to yours?
I plan on putting one of the sensor in a block that is easily seen and accessible with the fuel temp sensor. I am going to log fuel, boost before/after IC, want to know what this spearco core really is performing like and oil pressure

How do you plan on mounting the sensor for logging the exhaust pressure

Do you plan on extending a long tube off of the exhaust manifold to act like a heat sink of sorts? Or perhaps a nipple to a silicone line, to nipple and mount it in a block, or barbed fitting to female ¼ npt?

it would be nice to have a full metal body sensor in that situation.

Please get back to me as I would really like to know how you plan on keeping the sensor from not only getting fouled up from carbon, but keeping it at a happy temp for the sensor.

Did it say anything on the PDF file about the sensors operating temperature range?

Don’t thank me thank the guys over at the innovative WB forum. http://www.innovatemotorsports.com/forums/index.php

Its nice when a forum is so helpful and everybody is open to learning and sharing ideas, instead of on a big ego trip.

I have a -4 male fitting I'm going to weld to one of the main runners on my manifold. From that I'll have ~2' of tubing coiled up with the transducer at the end of it away from the turbo/manifold. I'm guessing it should work fine for the tests. I don't plan on permanently mounting the sensor.

Thanks setzup, intresting way to solve the problem.
Thanks for the link Max, those are the same sensors that the guys from an engineering forum that I peruse quite a bit recommended.

I just got mine today. I'm guessing they are used in air brake systems because of the quick release tubing T's that come screwed to them. I guess I'll find out how well they like gas and exhaust fumes I figured at $7.50 a sensor I don't have much to loose even if they do fail eventually.

Yeah, the ones that are hooked to my haltech I datalog that way. I don't datalog oil temp but I do have a oil temp gauge I look at.
