how fast has your car run at the track?

i stand with ted and jannetty racing!

I saw the link below a few years back when researching the subject on cooler thermostats. It was common for people with L67's (supercharged V6) to drop from a 195 to a 180, drilled 180 or even a 160 tstat. This was done initially as a bandaid to squelch knock before tuning was available.

To date, 10.19 @ 130.++ and that was before more mods. The car is 100% street trim and a daily driver and the car will be well into the 9's on its next pass. And thats with the stock 20's on the front.

and the other guy?

Oh, sorry, you meant fastfaster. I thought you meant Jannetty. That car is going under the knife again for a LSX 454 with a YSI blower and nos. No times yet. He keeps adding parts.

I go with ted. I have a 610wHP daily driver. I have already put on 25K miles on the car. Mostly all hard miles. I floor the car constantly. The car run flawless.

Question is 160 gets you more HP why not 140.. why not 120..

[blackonblacksls]

Ok well if 190 is better than 160, why not 290 why not 390?

I am still Not Saying I am Right, but I will go out on a limb here and say that I don't think Anyone Has More experience with the 2010/11 Camaro Than I do.

Again I could be wrong here.

I have tuned 244, 2010/11 Camaros to Date, combined HPtuners, SCT, Diablo.

I have Logged Thousands of dyno Runs Just on 2010/11 Camaros.

My Experience still Tells me For the Majority of all Street driven 2010 Camaros there is No Advantage to a 160 Stat.

In a Drag Race ONLY Car There may be a Small benefit.

There's a thing called...Law of diminishing returns!

Ted, I for one have not and will not challenge your skills and knowledge. The subject matter of the thread deals with the question of whether or not it is beneficial to run a 160* stat. If you read the portions of the tuning book I made reference to a few posts back, you will find these "technical" facts you requested. Raising the coolant temp from 160* to 180* requires a two (2) point increase in octane number. That's technical, not an opinion. Why is this very important? Guys tuned for performance are close to the detonation point. When exposed to high ambient air temps, IAT's, and high coolant temps, all you need for the finishing touch to take you over the detonation line is a tank of shit gas and you never know when you are going to get one. On top of this guys in states that only sell 91 octane are even more susceptible because they are locked in two octane points lower to begin with.

Guys who do not log regularly do not even know when they are experiencing detonation, KR. Moderate KR cannot be heard or felt. Furtherfmore the butt dyno would not distinguish a one or two or three degree KR when the ECM pulls the timing, especially on the street. In the summer I have even logged brief .5 KR in CRUISE.

In conclusion one additional benefit for the L99 guys is much cooler transmission fluid temps. This is another technical fact....high automatic transmission fluid temperatures wreak havoc on the fluid and internals. This morning I did some running around putting on about 50 miles. The highest tranny fluid temp I reached was two needle widths below the 180* guage line. I invite any automatic transmission professional to comment on being able to run 20* - 30* cooler automatic transmission temps. When I was running my stock thermostat I almost always over the 180* mark.

If these two technical points don't sway you...... then we'll just have to agree to disagree

160 Stats in a street driven 2010 Camaro are fine. I have driven many street miles, logged may passes and been on the dyno more times with more LS Engines than I can count.

When the weather gets cold of course get the stock stat back in the car. I have never had the temps run lower than 178 with a 160 stat in my personal car. They will vary dependng on the combination.

Ring gaps are tight from the factory on the LS3. About .011 to .012 from what I have measured. The aluminum blocks expands like crazy the higher the temp goes. Every test on the engine dyno that I have done on LS crate engines the leakages have been less at the lower temps. As we turn the stat on the dyno down the measured blowby (crankase pressure) has dropped and the power has increased.

Maybe I missed something......

Is the higher crankcase pressure responsible for the amount of oil a catch can accumulates, or for that matter, the amount of oil that passes to the intake if you don't have a catch can?
