Cooled by Thermal Siphoning The EcoBoost twin turbos are water cooled. Water cooling the bearings solved the problem. During normal operation, engine coolant is cycled through the center bearing. When the engine shuts off and the water pump stops, the coolant flow reverses and the EcoBoost uses thermal siphoning for water cooling. Coolant near the extremely hot bearing picks up heat, boils and flows away from the bearing water jacket. This pulls fresh, cooler coolant into the bearing water jacket, which picks up heat and cools the bearings. This cooling process continues silently until lower temperatures are reached, providing key-off protection for the turbo bearings. from: http://www.hendonpub.com/resources/a...aspx?ID=208618 and “The EcoBoost engine uses passive thermal siphoning for water cooling,” Plagens explains. “During normal engine operation, the engine’s water pump cycles coolant through the center bearing. After engine shutdown renders the water pump inactive, the coolant flow reverses. Coolant heats up and flows away from the turbocharger water jacket, pulling fresh, cool coolant in behind. This highly effective coolant process is completely silent to the driver, continuing to protect the turbocharger.” from: http://media.ford.com/article_displa...ticle_id=29657

"The EcoBoost engineering design life is 10 years and 150,000 miles. This series of engines uses standard grades of oil; synthetic oil is not required. The EcoBoost engine uses the same 5W-20 engine oil as most Ford gasoline engines. The EcoBoost engine has the same 7,500-mile oil change intervals as other retail Ford engines. It runs on regular grade, 87 Octane fuel; mid-grade and premium are not required. The turbos do not need any separate, different or more frequent scheduled maintenance. " Holy crap, that's pretty awesome. Do you know if the ecoboost engines run the same max timing on 87 and 93, or is it tuned for 91 and just pulls timing for 87? I can't imagine the ability to run conventional oil and 87 in a performance car would be necessary, but I guess when you're designing an engine for truck use these are valuable attributes. Cool stuff. |

Didn't really play around too much with the stock tune to know what the timing looks like with 87 octane, however I'm guessing the stock tune advances the timing and then backs off when when it detects knocking... I will say with the LMS 93 octane tune I'm running quite a bit more timing than I seen when I was running 87...

I agree this thread is pointless.

And therein lies the problem. The average car on the road today lasts something like 17-18 years. My current daily driver is 11 years old and is closing in on 160K miles, and still has a lot of life left. It still runs great, and doesn't use oil yet.
