Turbo Temps

[Ford_Power]

if you dont want to fang why the f*ck are we talking about more timing from lower temp engine???

99% of people here will not drive their car hard enough, and LONG enough for engine temps to rise above what the heat dissipation of the cooling system can provide. For most people they want maximum power when overtaking, or shooting off from a set of traffic lights... not for a race track where high sustained load is encountered.

To put it simply - given that engine timing advance is a direct function of engine coolant temp:

Engine temp at 92degrees, (allowable timing = 'x' degrees) car put outs *195rwkws, and;

Engine temp at 87degrees, (allowable timing = 'x' + 'y' degrees) car puts out *205rwkws

THEREFORE when you want to FANG it from the lights or for overtaking, maximum power is available due to maximum timing advance being allowable!

* = arbitrary values

well, its of little relevance to me and the tropical climate I live in, as I dont need to drive hard or for long, before the cooling system cant keep up. as I said before, the car will active thermofans sitting in traffic or looking for a park in a shopping center etc... soon as I get some airflow it sweet again. so if I wanna fang it from the lights, do I get any benefit? NO! hey goldie, if your still reading this, does your car with the cooler thermostat stay at the lower temp when your not on the M1? lets say your drivng down the gold coast hwy in traffic, what temp does she run then?

so, just regular driving thru town etc, even with a cooler thermostat, the car wont run cooler because its pretty much at the stock cooling systems limit capacity the whole time.

With folk down south, im sure this wouldnt be the case and you would get some benefit esp in winter or at night.

ive done some reading and found some interesting things on this subject. if you decrease the waterjacket temperature by 10 degrees, it lowers the RON requirement by 2. I was surprised that it was so significant!

I also found that car manufacturers have increased the thermostat temps and running temps deliberately in an effort to reduce emmissions and meet standards! bad luck for turbos hey?
