Quest for cool part 2a

[rattlsnak]

Well, I have installed the second oil cooler in the left front and installed SPAL fans on each cooler. The addition of the second cooler lowered the temp by 1/4 inch, and the with the fans on, it stays in the middle! Hence the next request. My temp gauge does not have numbers on it, so could someone take a pic of the gauge so i can see where my temps really are??? (im going to change to a numbers style soon!)
thanks, Marc

Sorry to Jack for stealing your title!

Centrigrade equivalents of each mark are written in extremely tiny digits way over to the side at the base of the lines. A magnifying glass and a lot of patience may be in order.

In a previous post about this, Emcon5 wrote:

The temps in C are marked on the edge of the guage, very small. The top edge of the bottom white strip is 60, the first narrow hash mark at about 8 o'clock is 90, the next mark (10 o'clock) is 120, and the start of the red is 150.

These convert to roughly 140, 194, 248, 302 F.

But different non-numeric gauges have different marking schemes, apparently.

This is from a web page I found:

The following is the numerical value of the various zones on the gauge; the letters denote various marks on the gauges.

911 SC/Carrera
A 140
B 194
C 248
D 302
E 328

C2/C4/993
A 104
B 140
C 194
D 248
E 302

1978 to early 1982 SC used a different gauge and I could not find the calibration data.

And by the way, the "Quest for Cool" topic is all yours, Marc. I'm done with it.

Marc,
There is a slightly less expensive alternative to the numeric P-gauge. Tweeks (Pelican maybe, Idunno) sells a sending unit that has connections for the stock gauge AND for an aftermarket round gauge. If you are using a gauge cluster or have a spot for one this might work for you. (I saw this setup recently on a modified 930).
Why do that, you ask? Well - it gives you the option to use a gauge with a more desirable temp range. The full 280 semi-circular sweep on this gauge went to 250F max, like you would see in an American car. I just like a more usable sweep, easier to see the needle move.
Haven't decided if I'll get one myself yet or just upgrade the stocker. On my stock gauge I can barely see those little numbers stuck in the corner. You'd think as long as they were printing them they might be put where you could see!

My 88 coupe typicall runs an arrow width 1/16- 1/8 inch above the mark about in the middle. Does that equate to 260 deg. F ? Seema alittle hot to me.
Where does your dial lever (Arm) average on a normal run say after 15 min. Above- below the middle mark, how much ??
