Guages (from left to right) are: Boost, EGT, FP, AF, Oil Temp, Oil Pressure.

 

nice

just wondering...how do you interpret the oil pressure reading?

 

What do you mean?

 

like....is there a low and high limit? what do you expect to see when you boosting?

thx

 

Ah. After the car is up to temp I its around 15psi at idle. Crusing its around 50-60 and WOT boosting is closer to 80. Not an easy guage to read accuratly, because of the spacing of the numbers/marks.

 

ic....if it is too high or too low...does it mean anything?
too low means not enough of oil to be pushed around?

 

It it started to drop too low I'd turn the car off. Odds are there's a leak somewhere and the SC would stop getting oil shortly. Also the oil pressure dash light would be coming on any second.

Dunno what too high would mean. Don't know if that's even a problem.

 

thank you~

too high means too much oil? or the oil return hose is blocked? will the blower get damaged if the oil pressure is too high?

 

Pressure is independant of quantity of oil...unless you run out then yes, your pressure will drop.

 

Is that how you've had the oil temp sender set up all along? It looks like oil should get to the sender just fine that way. I think I'm going to change my location from the oil pan to where you have it, it's good to know condition of the oil going into the blower.

BTW, do you get confused sometimes with all those gauges? I have one less than you, and sometimes I'll glance at the EGT gauge and wonder why I'm getting 14 psi of boost.

 

No, that's after I corrected the problem. I had the 90* elbow with the feed line where and the temp sensor swapped originally. Its all good now.

I like to pretend I'm flying a fighter jet!

Truth is I wanted Boost, EGT and FP on the pillar because I felt that they were that important. Oil Temp and Pressure are more for reference, so putting them down out of the way was cool. The AF guage is more of a place-holder. I don't care for it really, but its more useful than a voltmeter or something. When I have a need for another guage (maybe a J&S someday), the AF will get yanked!

 

Looks like a c0ckpit. You're missing water temp, voltmeter, tach, clock, fuel level, etc. Might as well complete the series.

 

No. 1 cyl head temp, no. 2 cyl head temp, ...., no. 6 cyl head temp, no. 1 main bearing temp, no. 2 main bearing temp, ...

 

Why didn't I think of that guys?

 

 

Glad you solved your Oil Temp problem...

However, aren't you worried about all that weight/stress on the S/C fitting? That puppy is weak to start out with.

 

Not until now I wasn't!

I think I'll be okay. The feed line supports the other end of the plumbing. The feed line is secured near the headlight, and doesn't really have anywhere else to go.

 

ejj and Stephen or whoever has an oil temp gauge:

what's the oil temp reading on your cars? will you guys let me know what is it like after a long run (say, cruising for 50miles) or after boosting?


thx

 

I see around 160-180 after extended driving or boosting.

I have an oil cooler waiting to be installed at the next oil change. Although I find that the feed line acts like a mini-oil cooler. Having air moving around the line and oil pan cools the oil down about 20*. After I stop driving on the highway, my temps hop right back up to about 180.

 

I'm seeing about the same. Sitting a long time at a light on a warm day I've seen it get up to about 200.

 

Considered an oil cooler?

 

If I ever see it get above 220 or so I will. Oil has an optimum temperature range for maximum lubricity, and you don't want to be too far below that range or you may do the blower more harm than good. Anyway, I'm waiting to see what happens this summer.

 

What is that temperature range?

 

Uh-oh, good question, and to be honest, I'm not sure. I have a reference at home that might say, if I can remember to look it up.

 

Me too, just wondering if you knew off hand. Something to read up on when I get home I guess.

 

180F, I believe.


I am looking into an oil cooler also. I am thinking about using a thermostat sandwich adapter. most of them are set to 180F. But first I want to see you guys's readings.


summer's coming up pretty soon.

 

If/When I install mine I'm going to get the same thermostat sandwich adapter (the one Kevin used). Much cleaner than permacools, and if you're going to make your own SS lines for the cooler (as I plan to), it will actcually cost you less to get the sandwich thermostat than permacools.

 

ic

so the B&M cooler itself is about 80 bucks?
mocal sandwich adpater with thermostat = $80
DIY ss braided oil line = ? (btw, how do you do it? I have seen those at Pepboys or Kragen, is that the right kit you use??)


thx

 

Ugh. Kevin sent me a detailed writeup via PM, which of course I deleted.

I figured doing the lines would cost $80. The reason I say the sandwich thermostat is cheeper is because to use a permacool type one would require 4 more fittings for the SS lines, which are about $10/each.

 

thx....I will ask Kevin later.

I checked several places online...seems like they are selling braided oil line for 8 - 10 dollars / ft.

 

Diet Coke adds a nice touch.

 

 

How do you hook up the oil temperature gauge? If you(or anyone else) please help me with a full how to, that would be great.

Thanks

There are 3 posts on the back of the guage. 12V, Ground and signal. I got the 12V and Ground from the cig lighter. The signal is just from the wire that's connected to the top of the temperature sensor in the pictures above.

Pretty simple.

 

Thanks for the quick response!! Where is the temperature sensor located?

Thanks again,

-Nick

 

Look at this picture:

http://www.ericj.org/maxima/img/oil_senders.jpg

There are two senders (follow the red wires). The one on the lower left of the picture is the oil pressure, and the one on the upper right is the temperature sender.

You'll need to find a location to mount yours.

 

I need a location to find to mount the temp sender? Did it come with your gauge? I dont think i have one? If not do you know where I can get one? Please help

Thanks,

-Nick

 

Yes, the sender comes with the guage.

I put it there because it was easy. If you don't have a SC odds are you'll have to drill and tap into the oil pan.

 

Do you know any alternative to drilling into the oil pan? Considering im not SC'ed ...maybe someday

Thanks for the help,

-Nick

 

You could 'T' into the stock oil sender location. Don't know what size fittings you'd need though. I do know that the temp sender is 1/8 (male) NPT. I don't know what the sender threading is though. I'm sure you could find out by searching though.
