this is why I dont touch the engine just spend too much and might as well get a true sports car.
I only spend on handling and looks for most cars

 

just came back from the redbull F1 it was great will post photos later, I was standing in a bad spot so hard to take photos.
sorry Jacky we did not meet up there but see still bumped into each other after in IFC.

 

Turbo cars just won't work well for HK mainly due to weather and Humidity

 

DY; did your temperature gauge stay or over 120 C, which I think definitely affect engine out put?
But I noticed that even recent hot days, the blades behind grill still close after normal running!
I intended to check this before shut off engine.
My gauge only indicated 110-115 C after pulling hard occasionally recent hot days, even at noon.
I saw those blades opened only when the car stationed with sunny days.
Could those blades be reprogram to open more time, cooling the engine or turbo?
Will this will help?

 

Yes mainly stay at 120C, also with the air-con on most of the time + traffic

What about the Fan noise? sometime its went -off loud for around 30secs.

 

Saw other forums that temp should stay 110 C, to which they even yelled too high.
Just small thing, have bmwhk reset it.
Didn't pay attention to that fan noise, but will check it out today

 

so far it is OK.
just look at Audi there Turbo is OK
check out kenji car next time the guy with 335 with 400hp

 

you guys with F10 have the blades behind the grill?
I had this on my pre lci and I took them off and the engine was alot cooler and the car was faster.

 

Didn't know this. So am I making the right choice to have the NA engine? Probably not, your engine has more potential for performance mods.

More specific on your 50K mod details please?

 

Yes, there are some 4 blades that is default closed, only when the sensor feels need to open occasionlly.
