Looks interesting Justin. Even in 32 degrees back in my home state your still wearing t shirts!

[@HorsePowerObsessed]

Lol I wasn't outside very long! 🥶

[@raymondchandler697]

Theoretical Question: If the engine generates heat that partly seeps through to the trunk but now is blocked, will the heat dissipate through the vents &/or or will extra heat remain in the engine compartment longer than planned, possibly causing some unintended negative consequences? . Would love to hear back from any engineers / physicists on this.

[@jamesmcclane9333]

Great question !!

[@HorsePowerObsessed]

I'm no engineer but this doesn't make any sense. The heat that would normally radiate into the trunk will be reflected and radiate out the top vents instead. We aren't talking about hundreds of degrees either.

[@giuseppesmith2320]

I had the same question, and it will probably void the warranty if it goes left. I don't think I'll be doing that to my C8!

[@bryceerban947]

Big like on this one. Last summer when it was 85 out on a 3 hr drive it was about 125 in the trunk. I thought about doing this but just use the Frunk more. Definitely will be a great product GM should do this stock.

[@HorsePowerObsessed]

Thanks! I agree, GM should do something with it.

[@tjmoneybags]

But what's it weigh? Im sure it was easy to justify weight savings. But for a daily... I'm with you.

[@HorsePowerObsessed]

LIterally weighs almost nothing. That's the best part. All that I installed wasn't even a quarter of a pound.

[@tjmoneybags]

@@HorsePowerObsessed i totally get it. But how many of our parts are plastic for the same reason. Ounces add up to pounds and every pound reduces speed. This ain't a Cadillac... it's a Vette!

[@sherlock1895]

Heat is a concern in the trunk. Not just for food either. You certainly don’t want to keep electronics, meds, etc in the trunk when traveling. In the Summertime mine hit 134F. I’d like to see the test in the Summertime. Wintertime temperature is no concern at all. Cheers!

[@Entrastang]

This will be my next project

[@JBsC6]

Thanks for the heads up. Looks to keep the trunk cooler.

[@HorsePowerObsessed]

You're very welcome. Definitely a good idea in my opinion.

[@budhorstmeyer9336]

Great concept. Now if they could just develop precuts like XPEL does for their PPF, it would enhance coverage and cut down installation time. Thanks for the product intro.

[@HorsePowerObsessed]

That would be cool! Maybe we'll see that in the future! Thanks for the support, my friend!

[@pinmagic]

For those worried about raising the engine temp by blocking the heat to the trunk, keep in mind that the engine is releasing heat from 6 sides, and you're only blocking part of one side. There's so much dissipation area around the engine, I would guess you couldn't tell the difference in engine temp with or without the heat shield.

[@HorsePowerObsessed]

Great point!

[@hotballer02]

Just use the frunk no money spent

[@jimihernandez2184]

I’ve notice that on my first drive to PCH, (80 miles) drive. My Canon 5D with extra lens was so hot I moved them to the Frunk. I thought about doing the same back in August 2020 but been deployed. Thanks for showing this and sharing.

[@HorsePowerObsessed]

You're very welcome! Thank you for watching!

[@RichW240]

I would install a layer of the foil material on the metal engine cover (behind the carpet) as well as the back of the carpet. A doulble layer of the foil should help to cut down on the frunk temperatures!

[@rudymontoya5298]

Thanks for sharing. Good to see there is an option to address this issue. Too bad GM doesn't have a recall on this problem.

[@HorsePowerObsessed]

Thank you! Maybe one day they will fix the issue!

[@randywilliams3195]

Thanks. I’m picking up my z51 htc this week from kerbeck and my golf clubs will be a permanent resident in the trunk so your video definitely enlightened me to a potential problem I wasn’t nt even thinking about. Might not be too bad in the winter but I’m sure those temps in the summer here in nj are going to be far worse. I will definitely be checking this out.

[@HorsePowerObsessed]

Definitely should!

[@richa9719]

Curious if you just increased the engine heat by blocking the heat escaping with that product? While it’s not optimal that the trunk is getting warm, it allowed engine heat to escape. With the heat shield you are trapping the heat next to the motor which will make the engine compartment to stay warmer which will make the engine be less efficient. Curious if you considered that?

[@stevedolan5065]

That seems to be a simple, inexpensive fix. I bet someone will come up with a molded heat shield that would simply replace the factory part and could be even more efficient. In the meantime, that’s a good way to go 👍🏻

[@corvettesupercars902]

*Great Tip and measuring it spells results.*

[@HorsePowerObsessed]

Thank you!

[@wazzman8760]

Have you done a follow up in the summer to see temperatures? Thanks

[@corvettesupercars902]

For sure an easy DIY and if you doubled it up it might also be even better

[@HorsePowerObsessed]

Very true. I may do something different with this come summer. Stay tuned.

[@jamesm.3338]

Any updates on this product as far as cost and design? Have they produced a pre-cut and fit model? And cost?

[@keppthorn2997]

Same question here...are these now pre-cut to fit?

[@45auto82]

GREATvideo Justin! I was wondering what mid-engines will do to trunk temps! Perfect timing! And, I really like the scientific approach you took to actually compare the before/after results. Definitely worth the effort and cost, especially if we carry temp sensitive Eq like camera film (yes...I still use some film cameras!), beer cooler....😎 haters just shut up! Heard it all before. Thanks for the information and testing. I wonder if you could get your supplier to custom cut the fitment? I bet they might!

[@HorsePowerObsessed]

Thank you! I will look into getting them cut to fit!

[@audieforet1443]

Good edit, nice video. Looks like some really good results!

[@HorsePowerObsessed]

[@adrianleusink1970]

Looks like a good solution. GM will likely follow suit and amend this rear cover with something similar in future production runs. Question tho: Where are the ACS wickers you installed recently? Noticed they're no longer on your car.

[@HorsePowerObsessed]

I agree, I hope GM takes notice. This video was actually filmed before I installed those. Good eye, though!

[@adrianleusink1970]

[@youcdtube]

Now when the ZO6 comes out if GM desides to put duel exhaust up high, I'm gonna have to figure out a way to grill hot dogs just.over each exhaust or a radiator system that can boil your water for tea or nespresso coffee delivered to the cabin. Then Wala!

[@HorsePowerObsessed]

🤣🤣🤣 I will have to see that!

[@superchief15]

A heat Sheild for C8, I like the idea! The Tesla Roadster they shot into space didn’t even have a heat sheild!

[@harrysmith2431]

That seems promising! 😎👍

[@HorsePowerObsessed]

Definitely! Interesting fix for a strange problem.

[@SquireSCA]

Do the entire bottom as well. Why? People with stock exhaust have that giant muffler box directly below the trunk, and a lot of that heat rises and comes into the trunk that way. Everyone focuses on the engine heat, but that exhaust heat might be as much or more of an impact on trunk temp.

[@cobyking144]

Cool !! So if you double up on the heat protector it should drop the temperature another 10 to 15 degrees. Thanks Brother !!

[@HorsePowerObsessed]

Thank YOU!!

[@73makoshark]

I doubt the heat differential will be as large in the summertime because the engine compartment is not going to get that much hotter while the trunk space would get hotter due to the higher exterior temperature. Just a thought. Be interesting to redo the experiment in July.

[@louisszabo9061]

Be sure to repeat it when the ambient temp is above 85F. I wonder if the temperature differential is constant, that is, limited to about a 30F rise above ambient.

One of the first things I did was put Dynamat and Dynaliner in my whole car.

[@HorsePowerObsessed]

Dynamat is a lot heavier and harder to work with than this stuff. Dynamat is also more so for deadening sound vibration than canceling out heat.

Sadly, you can't tell after yesterday and today's temperatures that this was actually filmed in January lol

[@fortijr]

Thanks for the great info. Is there a particular reason why they decided to line the carpet rather than use the material on the engine wall itself? I think it would provide better coverage and also be easier.

[@HorsePowerObsessed]

I'm not sure how much easier this would be other than installing on the removeable air box part but most heat insulation is not able to get wet. If it gets wet, it loses its functionality.

so what is the brand of heat shielding and how much did you buy?

[@HorsePowerObsessed]

It’s on my site, link in the description. I buy directly from the manufacturer.

[@richarddobreny6664]

Why not put that on that next access plate? I believe you removed that one when you did the air filter. That way, your shielding is right at the heat source. Do that in addition to the carpet.

[@HorsePowerObsessed]

I actually cut that part from the video I originally recorded because I wasn't sure if it could be installed there since it can get wet, etc. I'll find out though, because it definitely would help even more with heat if it could go there.

[@rm-dc6tx]

My question is will this cause potential long term engine overheating due to lack of dissipation of engine bay heat thru the rear of the car and the trunk

Would it be of any additional benefit to also line the left, right and back side of the trunk?? Is it just as easy?

[@HorsePowerObsessed]

It probably wouldn't be as beneficial because that's not where the majority of the heat comes from but it can't hurt.

[@jamesmcclane9333]

So you're testing this method on the coupe, would you venture to say that the heat index would be even higher in the trunk compartment on the convertible model?

[@HorsePowerObsessed]

Probably. I think the heat in general is probably higher in the convertible due to less passive heat dissipation.

@@HorsePowerObsessed Either way this fix should help with the heat pretty well with the convertible too.

[@arlenegaines5478]

How much different would it be to remove the HTC trunk liner?

I just looked at it in my HTC. Should be easier than the coupe. We don't have the mounting brackets they have. I just saw the 4 cargo net hooks, which just unscrew. There are probably the same plugs at the bottom, tho I didn't pull up my mat to check. But installing the heat shield should be easier on the HTC, because the carpet is more flat.
