Hey tom I understand how the 180 tstat works, but does it really improve performance that much? I mean I would understand when you are running a turbo setup but do you personally think its worth the 30 to 50 bucks on our cars?

I'm sure it would be a fantastic mod for anyone when coupled with a retune of the fan engagement points. My car gets to 210* + and it's only 80*F outside right now. After the car gets to 200+ you can feel the power reduce. Could just be heat soak, but how could a 10-20*F cooler engine not help with that?

In that case, why wouldn't Ford have put on a 180 T-stat as a stock part? Is it to reduce noise or increase fuel economy? Could you run a tune without a 180 T-stat?

Higher temperatures result in better fuel economy. Yes, you can run a tune without the t-stat; I have been for a year now.

The higher temps is there mostly for emissions then MPG , I wouldnt do a 180 thermostat if you dont have or not getting a tune

By changing the thermostat and a tune you wont loose any MPG but if you run your Focus harder then normal then its a hugh safety factor , lower engine temps mean less chance of detonation / spark knock and better performance , a lot of times better performing engine gets better MPG so by doing this you could gain MPG

Yes, emissions is a large part of it as well. Don't forget to mention the increased warm-up times in the winter which leads to increased engine wear and increased times for the interior to reach a comfortable temperature. A large portion of wear on an engine throughout its life comes from pre-warmup driving.

As stated above, the main benefit for this is people that live in higher-temperature states to help keep the ECU from retarding timing; this results in a better overall fuel burn.
