Default Infrared Testing Volume 4 **featuring GRIMMSPEED turbo heatshields**

In this installment of testing we will be looking at the GRIMMSPEED turbo heatshield for the WRX. We will be comparing the differences between no turbo heatshield, and a regular GRIMMSPEED turbo heatshield. The temperatures of the turbo area, TMIC, and the heatshield will be referenced in testing. Also the temperatures after the car has been driven will be compared with just idle temps as well.


The car is a 2011 WRX with a basic stage 2 set up. The downpipe of the car is a aftermarket brand with thermal wrap around it. The TMIC has gold reflective foil on the turbo side.


The environment in which the testing takes place is outside in 48 F weather. The low outside temperature will give great results that will not be affected by a high ambient temperature and will better show the effectivness of the products.

This study is geared towards the customer that upgrades their downpipe and finds that the OEM heatshield no longer fits, and no longer runs a turbo heatshield.

Product Information

Enhanced Turbo/Downpipe Coverage
(Keeps radiant heat out of engine bay)

Fits all Factory and Most Aftermarket Turbos on LHD cars only
(Designed to work with your future upgrades!)

Durable 304 Stainless Steel Construction

Intercooler Stays MUCH Cooler
(Turbo is very close to IC)

Fits Most Downpipes
(Even the HUGE 4" TurboXS!)

Only Heat Shield that works with External Wastegate Up Pipes
We knew when it came time to design this product we didn't want to just create another heat shield to add to the mix, but create another level of product. The basic heat shield would not cut it, we wanted every fitment of turbo, downpipe, and up pipe combination we could work into one design. We measured, cut, bent, welded, riveted, and after many tested prototypes we arrived at a heatshield we are extremely proud of. Other heatshields had problems with cracking, poor fitment, or poor heat coverage but we would not settle for this! So here it is, elegantly simple in style, but painstakingly engineered in design. It's what you can expect from GrimmSpeed™ Please note that this will only work LHD vehicles

As you can see there are tremendous benefits to running a turbo heatshield. The differences are shown below.

TMIC side idle temps
bare turbo--101
shielded--74

TMIC top idle temps

bare turbo--93.9
shielded--67.5

Good post and good data. You would be suprised how many people take the heat shield off when they install a downpipe. It can cost a huge amount of power when I tune the car.

I always recomend modifcation to the stock shield or an aftermarket shield like the GS unit here. A blanket and the shield is even better.

This is very cool that you have access to some cool infrared cameras like this. I'm glad to see the results turned out so well. It is very important to keep all of that heat suppressed as much as possible. Its such a cheap fix and easy install!

Thank you for doing this tests Brian!

What happened to the ones with the ceramic coating? Looks like you deleted all that info and locked the thread.

I totally agree and am very surprised at the amount of subarus out there that do not run a turbo heat shield. Hope this is the results they need to see to realize how hot it really gets under the hood.

There are other benefits to reducing underhood temps to surrounding componants as well under the hood, not just the tmic for power and response.

The scope of the thread changed and I created a new one catering more to the people that do not run a heat shield instead of being a heat shield competition. The ceramic coated heat shield is still undergoing testing.

I've been seeing a lot of new faces around here with new cars the past few weeks. The thermal questions are starting up again and I encourage you all to research before you buy and ask as many questions as you can. Ill bump the infrared testing threads and please contact me if you have any questions.
