Last year, i noticed that my Diesel performed badly in the Summer because of the heat. (90F and higher with 80% humidity, classic Montreal summer)
So i decided to make some small changes this year to try to reduce the under-hood heat and intake temps.
1st i removed part of the intake piping situtated under the Front bumper. (I was lucky that someone scratch my bumper while i was parked at a gas station)
I noticed that the car was taking most of its air from under the hood and by removing that section of piping, it would now take its air lower and on the side away from the hood :
You can see where the stock setup take the air and by removing the section you see on the picture, the car now take its air about where the Red circle is. If the bumper is removed, this is a very easy thing to remove.
The 2nd thing i did was buy a Turbo Blanket, the link is to the exact model i bought : https://www.ptpturboblankets.com/col...-blanket-black
Here some pictures of before and after :
The size is perfect. The only probleme i had was that i couldnt tight the left side of it, since too many things are in the way. So i just fasten the right side of it and be sure envelope as much of the exhaust side of the Turbo. After installing it, i went on a test drive and pushed hard. When i cameback, it didnt move by a milimeter, since its very snug already w/o securing it.
My goal with the Blanket was the reduce the heat transfer of the Turbo to the surrounding items under the hood, especialy the Intake side of the Turbo. If you look in the picture w/o the Blanket, you can see the pipe for the Boosted air going to the intercooler passing right under the Turbo. If with the Blanket i can reduce the intake temps by just 20-40F, it's worth it.
Only in the summer i will know if this made a difference, but im sure it wont be worst.
