Let me help.
GM engineers picked 190 for good reasons, why do you shadetree monkeys think you know better ??
Yes I did stay at a Holiday Inn Express last night so there !

 

You need to go back to the 60's because your thinking is much like the reluctance to have flush toilets... your spuck pure bullsh|t from your back door experience, and try to convince people here that you know something about cars...
Ive devoted my life to progressive technology. GM didn't make this car by accident
back in the 60's Corvettes where getting 12 miles to the gallon and producing little hp compared to todays engines.. The PCM is your friend... show me a car from the 60, 70 or 80 that can produce 400 crank HP and still get 26 MPG. Those old cast iron blocks are dinosaurs. much like most of your post...
You should stick with whatever field you have taken in your life and leave automotive technology to people who know something about it...

You mention high temps for emissions purposes like it was a well guarded secret...and you were previe to this all by yourself.
WE designed that in so you would not have to pay a gas guzzler tax...we had to design the engine around those temps for the best overall performance, No gas guzzler tax was a top priority. the engine speaks for itself, so go back to the 60 where you belong. MOst people here bought their car because it was the best bang for the buck...that because we designed a 100,000 dollar sports car with a 50,000 price tag. The credit goes to GM engineering and project managment for keeping this car in budget and delivered on tme.

 

What I want to know is.....................

With the size of the typical C5 cockpit, how do these egos possibly fit?

 

You're a funny guy ET. The problem is that you don't know half as much as you think you do. Either that, or you've had your head up GM's a s s so long that when they fart, you speak. GM designed the Vette with multiple goals in mind, no gas guzzler tax, excellent performance, low emissions being some of them. (I chuckle at how small a part of that engineering you probably played) With multiple goals comes compromises, one they chose was lower NOx emissions with a small penalty in horsepower. And that's fine, most folks won't miss the HP they left on the table. But some folks want to change the compromises, and modify their vehicles for more HP. An easy, inexpensive way to pick up a few HP is to run it a little cooler. It's really that simple, but I'm sure that because GM didn't do it that way, "NIH", or not invented here will intrude on your thinking. Ask any of the big-name aftermarket tuners of engine builders who work hard to make HP, they will also tell you to run it a little cooler.

BTW: If you check on the C6 sections, you'll find they are also making more HP and running quicker times when the LS7 engine is cooled down.

 

Sorry I can't resist.

Who knows about the science?? My car definitely feels stronger in the morning after a few minutes of warm up but not actually HOT. And it feels stronger in the winter than in the summer. I thought it was making more horsepower when it was not fully warmed up to 190 - 195. so I put in a 160 thermo and the fans come on at 189.

OK, I'm all

 

Hi Guys -

I have a 160 in my Z - Lou Gigliotti recommended it when I had the headers put on.

The oil gets up to 195 on the cool days we have had around here this spring.

They told me it was to keep the pcm from retarding the timing when the engine gets hot.

I have had two of the better tuners in the country (my opinion) work on the PCM, and both of these tuners thought that a little cooler would make a little more power.

After the installation of my headers, and the 160 stat, I got almost two mpg better mileage on the 800 mile return trip thant I did on the drive down.

On a side note , I want to hear everyone's input so that I can make my own decision.

I can respect anyone's opinion without the need to call people names and use poorly masked profanity.

I ask that you gentlemen do the same, please.

best regards -

I agree with you on all counts. What do you say guys?

 

ET, why dont you show us an LS1 motor that has blown up because of a 160 stat? You cant! So why preach your line of thinking when you cant back it up with facts?

Again, your past career experience may look good on Monster.com, but it still will never prove your thermostat theory!!

Until you show proof, your theory on 160 stats is all "he said she said" BS.

 

So GM can pass emission standards easier on the production cars.

 

You guys are all smoking some good weed! I need to get me some....but can't remember if it will lite up at 160 or 190 degree flame......SHIET I hate it when that happends

I just put in a 140 degree.....................

 

With out my 160 t-stat, performance hood seal and chrome exhaust plate I wouldn't be able to run 10's with my stock LS-1.

 

Winter/Summer difference? Colder air is more O2 dense and thus the SOTP feeling that you produce more horsepower in colder weather... but that is irrelevent to water/coolant temps. I have to team with ET on this one. And I'm a Phys Ed major

 

I am going for a 100 degree one.......hell why don't I just leave it out?

 

Corvette Magazine, Jan '06 issue, page 36, Tech Nerd article titled "Fighting A Temperature"...sheds more light on this matter...

and I wanted to post so I could do this...

No clue!
I'm running a 160 because that's what East Coast Supercharging provided, probably reduces detonation.

Hell, I didn't know I had one. I thought it was air cooled.

SAAAAYY! Are you guys makin fun O' me? LOL

 

Two companies are closely tied to GM Racing -> LPE and Katech.
LPE recommends 160* TStat for High Performance apps.
I'm not sure what Katech would recommend?
I'll go with LPE's advice.
FWIW.

 

sorry for the hijack.

Oh, and lest I forget the requirement for posting in this thread:
