I've posted this many time... Heat is necessary to keep the oil and additive package from being destroyed by shear. There is a reason why the LSX design can get 400,000 miles. And it not because it runs cold.
There is some truth to the emission issue, but Heat was the denominator to make the First 200,000 mile motor design on the planet. when the oil is hot and flowing there is no shear..Running below 190 is a motor killer.
You can listen to those who got their knowledge from their grandfather who worked at a Buick dealership in the 60's or you can get the truth from an actual insider to the design of this car..
Tuners???? you pay them to give you more HP... they cool the motor down to allow for more advance, which gives you more HP and they know that the factory tune is rich as a protective measure, and they take advantage of that rich mixture. What they don't tell you is that running an LSX motor too cold will shorten the life expectancy by a more than anyone would want... since a cold motor reduces the clearances and puts too much shear pressure on the oil which destroys the additive package...you motor runs unprotected, especially the top end.. WE have seen this in GM engine test lab where a cold motor will burn through piston # 7 and its been documented here for that very thing.... the OLM and the heat specific additive specification in cooperation with Mobil Oilin the LSX Y body engine where part of the certification of complaisance for the first 200,000 mile production engine on the planet.
Like I always say.. Be very careful who you listen to on this forum.. Lots of urban legend and especially " Alternate Facts" untrue facts

As a tuner here I would like to respectfully discuss this with you given your back ground.
The discussion of stats is something I typically stay away from because in a sense everyone is right and everyone is wrong, but I would like to explain to you in our level of testing why we use a colder stat. Although I do agree with everything you posted.
We have just about every record for fastest stock LS1/LS6/LS2/LS3/LS7 and the LT1 now. Maybe someone has surpassed one of these, if so I apologize to that person, but you get the point that we test these engines at a HP limit that I don't know if GM does? You would have to answer that.
If those vehicles were raced with a stock stat I firmly believe that not one of them would be together and still being raced today.
Not from oil breaking down, but from detonation. Does anyone disagree that increasing HP will lower engine life? I doubt it, but I can argue that detonation will take that engine out much faster when being ran over 200* once the HP is increased.
Oil is changed much sooner on those type of builds then GM requests, and often better oil the Mobile 1 is used.
Here is an example of a car that is hard to dispute that the colder stat is the right direction for this build. (IMHO)
That car has over 2500 passes on it and is daily driven on nice days to work by the owner, Jersey to NYC. It has won more races than I can remember including season championships. The engine has never been out of the car or torn apart for other than a cam install. I will go to my grave with the firm belief, from years of track testing, that if we left the stock stat in it that would not be case.
It's I guess what you could call the better of the two evils, just depends what side of the pendulum your on as to which evil is your best option.

I have a question about stats. I think I understand how a 160* stat will work at the drag strip but if my car is driven on the street for say half hour or so and gets up to 235* with tough driving and the fans are programmed to stay on and working isn't the only thing I could do is increase cooling capacity ie bigger radiator? Sorry for the run on sentence. I have solved the problem with a dewitts and spal fans but many were telling me to change stat but could not explain how this would help on the street.

I've asked this in many threads so others could see a better explanation and understand if you are over taxing the cooling system a lower stat is not going to do a thing but I got mostly condescending answers from people saying "well my tuner said to do it so I did....and I don't have a problem so it must work".
