I don't think the 160 stat will give you a gain. My point was that I did not lose 18 hp on the second pull after the 160 stat. To give you the numbers:
Stock: 1st pull: 334 rwhp, 2nd pull: 316 rwhp
After 160 stat and LG Pro Headers: 1st pull: 359 rwhp, 2nd pull: 360 rwhp

The car is designed to run generally at a higher temperature for maximum efficiency and low emmisions.
All the 160 does, is lets the coolant circulate sooner than, say a 180. But the ultimate and equilibrium temperatures end up the same. The motor does not run cooler. We have no trouble here in AZ (with common temps over 110) with the std thermostat.

I find that to be odd because mine does not.

How much faster does your car go at 185 degrees?

Most of the people I have talked to said there is no downhside to going to a 160 thermo, and that there are distinct advantages. If that were true, then why does not GM simply use 160s in the car to begin with? My question is this. What are the advantages and disadvantages of replacing the thermo? I live in Chicago and drive in very cold weather (13 degrees last week). Any issues?
Something to think about. For those of us with automatics who get stuck in crazy stop and don't go traffic in the summertime. Very hot transmission fluid will form varnish. Once the fluid heats up it takes quite a bit of time to cool down.
A lower thermostat will keep the transmission fluid temperature at a lower temp and possibly make the trans last longer (automatics run the trans fluid through a cooler which is part of the radiator). On the minus side beating the car when the fluids are cold will decrease engine & transmission life.
Why the sudden interest in thermostats when there are new heads & a intake to argue about

When you drag race it will go faster because the problem of heat soaking the IAT will be reduced. When the car sits and idles the coolant temperature increases. A lower stat will allow the car to cool off quicker. Thus reducing the amount of timing the IAT would pull as it gets hotter from the radiant heat around it. You will actually see this if you run HP Tuners in the scan mode.

Roughly 2/10ths quicker with an almost 1.5mph faster trap speed in the quarter mile.

160 deg stat
Hi all,
I watch my temp all the time on the dic and it does run cooler in all conditions than before. Is it good ??????
LG in Dallas recommended it with the header install.
Hay Hoonose is that an old kawasaki H1 500 in your sig?

And I understand about the drag racing and icing it down.
But my main concerns are about the temp and everyday driving.

Great bikes for their time. I had a '71 (Blue) and a '72 (Orange). Worlds fastest production motorcycle in '70 and '71, then the '72 H2 750cc took the title. Terrible handling, poor brakes but un-godly fast in a straight line.

Terrible handling? More like evil handling (like it had a hinge in the middle). One of the worst chassis ever designed IMHO. But fast...

My '69 was wrecked and it had Bighorn (!) forks on it when I bought it for $800. It had a bad steering wobble over 120. Sold it for $800 6 months later. The '70 was rock solid at that speed. Also bought used and sold within 6 months for $800. I don't recall them being very good at cornering. But awesome wheelstands! My '71 Norton was much better in the handling dept. But topped out at less than 100 mph.

They were wheelstanders for sure, you couldn't keep the front wheel on the pavement. A choice from the Factory in '72 was CDI ignition OR front disc brakes, the lack of stopping power of front drum brakes at 1/4 mile speeds was scary.

my first mod was the 160 and cartek fan module. went back to track and went faster in way hotter weather by a tenth but also can hot lap no loss by heat soak have hot laped 5 straight runs went faster each run
