Yeah I can see how that should get covered by warranty - my "issue" probably won't.

 

And I agree it's very dangerous to drive with unpredictable power.

Actually they did do some work to have it warm up faster as well according to Ford's press material: http://1l-ecoboost.f...stEngine_EU.pdf

 

"A compact cast iron cylinder block design 
features a small cylinder bore (71.9mm) 
and a long stroke (82.0mm), contributing 
to impressive torque figures. It’s also 
extremely strong, allowing a gap of just 
6.1mm between the cylinders – helping 
achieve faster warm-up and improved 
fuel economy."
 
But yes the iron will warm up slower than aluminium, and retain the heat longer.

alexp999: How did it improve the drive-ability ? (for instance turbo lag, low-end torque or similar?)

 

The reason I'm considering getting it done, is because of turbo lag - but of course there's no guarantee it'll change that.

I never really thought about the affect of the outside temperature on the power of the engine, but it makes sense when you think about cold air intakes. Does this mean that in winter cars should me noticeably more powerful than in summer? And what about fuel efficiency? I'd think if cold air is better then MPG should go up in winter at least once the engine is up to temperature, but I've heard cars are supposed to use more fuel in winter, I never really noticed myself.

 

The reason MPG goes down in winter is largely because the engine takes longer to warm up, and thus you drive longer with auto-choke enabled.

 

Furthermore you usually have the heater all the way up, which further prolongs the engine warm up (the heater "steals" the heat from the engine), and finally heated windows use a lot of power, so the generator has to work harder, which in turn also costs fuel.

I'd actually expect a NA engine to lose more power than a turbocharged one, since the intercooler should help drop the air temperature a bit.

 

But I've no idea whether this theory holds true.
