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. :th_coolio:

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/collections/t3-t4/products/t3-t4-turbo-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.

Buy an inexpensive non contact laser temperature gun and take before, after and during temps on the intake side of the turbo to see if it makes a difference. You would need to remove the blanket for the before, but it would be worth it to verify your theory.

obd2 reader gives ACTUAL intake temps.
I dont know what are the actual intake temps, but i have enough experience to notice Heat Soak.

I'll see this summer how it does, but today i did about 200 miles with many Full throttle pulls and it was better.

Do you personaly have a way to check your intake temps, because if you do and your deleted + race tune like me, we could make some comparaison.

i have a obd2 reader

so yeah can read actual intake temps

not deleted, yet...stock tune.

Ok, i think my Tuner from Fleece or Vermont tuning can do it too.

We could compare with stock car, but it wouldnt be accurate.

Ive been running for a few days now and im VERY happy with the results : The car is way more responsive and pull harder, even after 20min straith of full throttle runs.

Im gonna check Intake temps just to confirm how the car behave, but im 100% sure it is working.

It varies so much I doubt you'd get any decent hard number.
In all honesty i dont realy care, since i know its working. :)

Do you have a program that i could put on my Laptop to show all Stats for my car, like temps, torque, ect...?

Yep! Really the best 'scanner' you can get. Can't think of anything that comes close.


Also I know Levi makes top notch blankets or socks. His site is here https://turbo-performance-products.myshopify.com/

Not sure if his fit the cruze, I can't imagine why they wouldn't.

I just did a test drive with my Laptop in my car and checked some stats : Do you know where is the Intake temp taken? (Like b4 the turbo, after the turbo or in the intake)

Curious as to how a turbo blanket, which confines heat mostly to the turbo increases performance? Isnt the whole point to reduce turbo temperatures and not increase them with a heat shield or blanket. I would think that a heat sink or fan on the turbo would be more effective to " remove" heat. I know with my supercharged cars , I try to make the SC run as cool as possible.

A blanket may reduce overall underhood temps to the detriment of the actual turbo running hotter. I know when I run the car hard that I pop and prop the hood for an hour or so to let it all cool down , particularly in summer heat.
