160° 'stat.
Hey look at all the C6 guys running 150°'ish temps.

I think before I buy another car I'm going to ask if it has one of those suckers in it!

The most interesting thing I saw was the post by Buffy on the first page...
"Changing the thermostat won't affect the fans, they'll still come on at the same point (points, actually, as the C6 uses a proportional fan control where the fans run faster the higher the temperature)."
Is this really true for the C6??????
I have often wondered about both a variable speed electric water pump and variable speed fans the would optimize the control of coolant temperature.....has production technology finally caught with one of my daydreams???

Hot diggitty, this guy's gonna single handedly put Ron Davis, DeWitt and BeCool out of business.
I wonder how many of those guys have the "Tornado" installed in their intake.

I installed a high capacity SLP radiator in my Camaro SS a few years back. Absolutely no difference at all in coolant temps, until I also installed a low-temp thermostat.

P.S. I read the C6 Thread. I don't see anything comical. C6 owners have $$$. They don't have to work on their cars. That explains their lack of experience in technical matters. I do agree with running a 160 thermostat.

With my 160 T-stat drilled, my coolant temp would be 155 degrees when its kinda cold in the morning. Off-idle response, especially with 12 degrees of timing felt like some SOTP you'd feel with a TPI. Tires seem to spin too easily, even on dry pavement. The ECM must also add more timing and fuel enrichment when the coolant temps are cold like that.
When I had on a 195 degree T-stat, the car would feel like it had much less SOTP power and would occasionally ping when hammered off idle. I had to back down timing 6 degrees to avoid hurting something when the motor was that hot. Plus I think the ECM commands less timing advance in the chip when coolant temps are 190 degrees and above.
There has to be at least a 20 hp/10 ft-lbs of torque difference between the coolant temps of 155 to 195 degrees. Low coolant temps certainly feel more robust off idle, especially when the air is cooler. Just a quick observation.

how/where to drill thermostat?
[QUOTE=kopbet89c4;1558599839]With my 160 T-stat drilled,
hi kopbet89c4,
i was just wandering mate about you mentioned the 160 t-stat drilled!
what does this mod do please?
any pictures on how/where to drill it?
is it worth while doing?
thanks

Basically to drill the T-stat, what I did was drill 2 1/8" holes on each side of the shell plate. What a drilled T-stat does is help burp air bubbles out of the coolant easier. Bad thing about it is it will take the car a little longer to warm up and will seem to level the temps about 10 degrees lower than it is rated. Sometimes in cold weather, my 160 T-stat will have the coolant temps stay at about 150. Although cooler temps cause the car to use more gasoline due to being in open loop mode longer, nevertheless, you feel a snappier throttle response around town due to the extra spark advance the computer adds when the engine is cool. After 190-200 degrees, the computer uses a less aggressive load/rpm/spark advance table, hence less power. I have programmed my fans turn on at 175 and off at 165 so my ECM can use a more aggressive timing curve.
