What temps are you ls1 running. After like 25 min of driving my ls1 goes up to 180-200 and this is normal local driving shifting usually before 3k rpm. is this normal?

a little lower than OEM settings.

depends what thermostat you're running and fan turn on/off temps.
once my stock thermostat opens at 194*-195*, it (obviously) does not drop below. it can, however, get up to 220*-230* before the fan kicks on. these are normal operating temperatures (195*-230*) for a stock LS1.

I've been operating up in the 220* range and have had some concern. Is this really within the normal operating range? I was thinking I still had some air in the system.

OEM low fan turn on temp is 226 and high fan is 235.

+1
220* is fine IMO. GM lets the motor get to these levels for thermal efficiency (gas mileage) and reduced emissions.

But keep in mind, manufacturers nowadays are basically sacrificing everything else (like wear) in the name of mpg and emissions. That is impression I got from an article I read, anyway (It was about manufacturers specifying low viscosity oils, because it allows them to meet federal fuel economy standards. The author of this article actually speculated that total fuel economy over the life of the engine would be lower due to wear). Not that I know what configuration will yield superior wear characteristics...

I dont think my fan even comes on. havent really check but I know the fan comes on when I turn the car off and it stays on for a few minutes.
and thanx guys for clearing that up. I was concern that I was overheating. and the hood gets so hot you can probably fry an egg on it lol

Most people change there fan setting to 210 when they program their PCM. 195 -210 is perfect IMO. I think people who run 160 thermos are too low and there is no benefit. To each is own.

i keep mine at 195* all the time,
fan comes on at 200* and lower it back to 195 in matter of seconds

I'd rather have an engine running at 220 than 160 as far as wear is concerned, especially important to have the oil temps up in the operating range compared to low

ditto.
not saying the engine wear claim is right and i'm not saying is wrong... but, i will say this; extraordinary claims require extraordinary evidence.

So what should I set the high limit alert on my gauge to? 235*? 240*?

Well, I''m not actually making a claim, I'm just saying I got that impression from an article. However, even if I were to speculate, I would never suggest that 160f was ideal for wear (although I wouldn't be surprised if wear was decreased at, say, 10 degrees less than the temp. at which emissions/mpg are best (this number is totally baseless though)), because the oil film is dependent on a certain internal clearances, in other words expansion from heat. I don't know what that temperature is, or how much crankshaft journal clearances tighten up with heat, but I think the pistons expand in the cylinder bores quite a bit.
Does it really seem likely that long term wear, emissions, and fuel economy, are all best at the exact same water temp?
