    yep the turbo lives just below the strut brace so id expect it to be really hot after a burn

    stays hot for ages too... If you open the bonnet at night after some spirited driving, you can see the exhaust manifold glowing red hot too....

    Any pic's? Did it help reduce heat and did you do it mainly to cool down intake?

    Yeah I heard a chap talked about it a couple of weeks ago, he also did it to reduce heat at the air-intake manifold. I'm fitting a FMIC soon and maybe a BMC CDA so I'm gonna tear apart the entire front anyway. WILL strip all unnessecary plastic :w00t:

    Cool yeah i undertsand the turbo is just there, i could not belive the heat what was coming from the engine when i popped the bonnet, and that strutbrace was too hot to touch and took so long to cool down, i was just curious as if it was totally normal, i supose with a remap too the turbo is working harder therfore gives off more heat,

    It will be very hot, even more at this time of the year. You will really feel the heat even on the bonnet.

    And as said above, the turbo is right there underneath, so expect it to be really hot.

    I travelled about 4 miles to a friend's place when we swapped the turbo. After 5 hours, the area around the turbo was still warm...lol

    After a proper drive you can make the turbo glow red hot. So yes I'd expect it to be slighty warm.
