Yep. High intake temps mean lower power output.

Hot air is a barstewards with turbos, spring and autumn have ideal conditions I find in the late morning or early evenings when it's nice and cool but roads are still dry

Its just a way of life.

Hot weather affects N/A cars too.

WMI and a decent intercooler make all the difference apparently

I don't think my TDI is suffering too much, although I guess it depends whether your intake is a sealed standard jobby or one thats open to the heat of the engine bay.

I have noticed my TDI is a little less responsive when the weather is hot. Not massively but enough to notice. I was seeing intake temps of 40+ degrees last week with standard enclosed airbox.

Cold air is more dense therefore contains more gsm (air mass) for the same flow amount vs hot air...

More air mass + more fuel matched by the ecu = more power. This applied to all combustion engines, turbo and N/A.

I just turn my boost up!  :wink:

Seriously though, my R handles the hot weather much better than I thought it would.
Golf R gone.
