160 Degree Thermostat and Car Issues....

GM does run the 192 t-stat for emissions, hotter the engine,cleaner it burns.
Oil temp does follow and heat exchanger tries to maintain it.Temp with the t-stat still hit's the range which will dictate the lower end engine temp -ie bearings ect.
BUT- why does GM run a big cooler on the Z06's? Most Z06's will run oil temp in the 140's all the time... HMMMM

For power, the 160 t-stat will cool the motor quicker than the 192 because it opens earlier. You see this very good while aggressive driving or more in a road race situation.The dyno could bring it out too.My car hit 240 degree's when stock,now it goes to 210 on full load pulls.From our testing the cars do make more hp/tq doing a pull at 185 degree's than 205 degree's.

Discuss.

A cleaner burn also means more power extracted from same fuel.

Thermostats DON'T cool motors Radiators and Fans Do.

I have done the testing on water temps time and time again and just have never seen anymore power at 185 than 195 in fact the other way time and time again.

Again unless your being more aggressive with timing I just don't see the advantage.

Your talking about a Dry sump system vs a wet sump system Oil temp on the dry sump is measured in the tank before it re enters the Oil Pump which adds heat then enters the engine, which adds heat, I assure you it comes out of the engine well over 220 degrees or more, NORMAL OIL TEMPS.

A wet sump system must expel it's heat through the cooling system so it is designed for that.

I am confused here. I have seen the stats for sale for years saying that they will add HP and now I hear they can ruin a engine. One guy says no good, one guy says good, what are we guys to do. I mean is this another rip off! I mean I see shootouts with different products and one seems to always win all the time, how are we the little people who look to some of you guys to know the true facts. You might even be partners with some of these other products for all we know. I know all I can do is read and make up our own mind but this gets confusing. We don't have a dyno in our garages so we can prove it ourself, but it does make me wonder at times.

Ted has me wanting to take mine out now! LoL! I know Ted knows these cars and has no reason to lie about any product. I don't know what to do!

Sorry to confuse you, Was not my intent.

My intent is FACT Finding, and So Far I have seen NO FACTS that a 160 Stat is better than a 192 Stat that the GM Engineers Designed in to they're engines.

Therma stats control the flow of water/temp control.The radiator/fan cools it. The waterpump circulates it. Works very well in these cars.The whole system working together controls the temp.

We have a few road race Z06's with multiple oil temp sensors. The engine oil temp is cool during normal driving.While pushed hard in a race the temps will reach 220-240. I too like oil temp 200-220.

For power production- We see more power from a cooler engine than a hot engine.Always have with the LS based motors.Tested it on a few new Camaro's and they all droped power on each run while doing multiple runs from 160 to 230 degree's. There are too many variable's to back this up 100% due to intake heatsoak ect.

So,thats my opinion about this. I'm always open to everybody's findings/idea's.

I believe it is just a left over from the days of the Old Small Block Chevy when engine cooling systems were not so sophisticated and it was an advantage to start lower before a run and not have boiling of the water or steam pockets forming in the heads.

Our Current Cooling systems are some of the most advanced systems on the market today, it all started with the Reverse Flow Cooling system on the LT1 designed by Evans Cooling Systems.

This is What allowed High Compression on Pump Gas without Detonation.

Evans Cooling System Rents my Dyno occasionally and I have seen Things Only GM Engineers get to See.

I will leave it at that.

subscribed....

eating popcorn and reading.... i like where this is going.


and to answer the person who asked before "who do we listen to?". I can tell you this.... both Ted and Slowhawk are very reputable with their knowledge of ls motors. I am sure here on camaro5, ted is more known, but if you go to the "mainstream ls motor forum (ls1tech)" it would be vice versa with everyone knowing who slowhawk is. I believe both parties would agree to disagree and that there is always more than one way to skin a cat. Every company has their own ways of building motors. In a predicament like this, you can either keep a "brand loyalty" to either company and say XXXXX is right, just because. Or you can play jury, and watch both parties give their arguement and make a decision for yourself (because neither one is right or wrong).

For myself, I'm going to subscribe to this thread and see what other information I can learn for myself

[JANNETTYRACING]

I just find myself constantly Learning and Understanding New Technology and I am not One to Get Stuck with It worked Before so it should work now.

And I am also Waiting to hear or see Technical Data that Backs up the Claims of the 160 Stat Theory ON The current engine offerings.

So would you guys recommend taking the 160* tstat out?

No, as I stated, we have sold several thousand of these over the years and never had issues. They only lower the temp 10-30 degrees and I have used them on my own cars for for years. SLP has been selling these for years , and included them in packages they sold for cars that they offered a warranty on. You will only have issues if you don't properly bleed the system. In terms of driving I have never even noticed mine..however anytime something runs cooler. Unless it's a Hemi, they like running hot and act funky with anything lower than 180.

Sweet, I'll leave mine in! As I said earlier, I've never had any problems with mine in soooo.... if it ain't broke I won't fix it

It wasn't broke to begin with

[john468]

So SLP has sold these for years and I do remember them doing so and still do. But my hopefully last question is what will I gain by changing to the 160 stat? I don't care if its 1 or 2 HP because at the end of the day it adds up. But tell me again will I gain anything or lose. i need to tell you i live in Florida where the heat is terrible and the A/C is always on, Thanks again
