That does not sound right even converting Celius to Fahrenheit that is only 392.
Where is the probe?

 

10x C. I got it to 42 on the first day, hills, but i get it to 35ish max now. PO said dont go to 48

I take it yours is Fahrenheit

 

12 x 100=1200*
you don't want to run these IDI's past 1300, the cast and the aluminum cant take it.
don't drive the truck much right now, because I got things to do to it. and shes not ready, im also doing another truck too lol


don't need a trans temp with a ZF
I could use an oil temp....

 

Remember that the temps you see depend on where your sensor is. If it's pre-turbo, after the up-pipe? I think 1150 is a good long-term safe number. If it's right in front of an exhaust valve in the exhaust manifold? Might well be a couple hundred higher than that. Post turbo? Probably lower, like 950 or something.

Also, short jumps(60 seconds or so) above that shouldn't be a problem; while the exhaust might be 1300F, the metal around it takes time to heat up. And there is a decent bit of cooling for the aluminum pistons, in the form of oil jets spraying it from the bottom.
So try to keep long-term temps down, short-term spikes probably won't hurt much.

 

probe is inbetween # 6&8 cylinders on the manifold.


after my last set of heads cracked to shyte, better safe than sorry.

 

How does that tach hook up? Does it utilize the factory sender or is it like some I have seen that puts leads on the alternator?

I like the look of the Isspro stuff but it's not the cheapest!

 

Dash mounted gauges are in a box I built out of some scrap aluminum I had lying around. Not perfect but it gets the job done and I would rather build something than buy it.














I had to add a second fuel gauge, long story, and threw in a voltmeter at the same time. I modified parts of the original ash tray, fabbed up the rest and welded it all together to get the finished product. Since I don't smoke and had other plans for a aux. power plug this turned out to be a great use for the space. As a bonus the wiring for the factory light in the cigarette lighter worked perfectly as dimmable power for the gauges.

 

the tach has 1 signal wire,
I have not hooked it up yet.
still lots to do on the truck
