Why the C8 trunk is hot and the easy fix!

Please subscribe to the channel so I can keep bringing you great content! Here’s a great how-to guide for fixing the issues where heat from the engine bay warms up the rear trunk on the C8! This project can be done for under 50 bucks and in about 30 minutes. For those concerned about where the heat will go, it will rise out the vents on the coupe trunk/ hatch lid and the vent on the HTC lid. If you are concerned about heat on your air box, wrap it too.

Glad I could be of help, smash that subscribe button and check out my other c8 videos!

[@Gmoney6272]

great vid, now do one on how to kep water out of the engine bay.

[@GhostSpeedShop]

I mean, I did one for strut covers to keep the water out. Other than covering the vents and rear glass there’s not any great methods.

[@Jacob_LV]

Just did mine.. it looks so good…, thanks for the tip!!! ✌🏾

[@C8bluebandit-yg4mc]

Great video and definitely a better and cheaper option than the kits out there. Thank you

[@GhostSpeedShop]

Thanks!

[@DewinVega]

I wonder if this increases engine temperatures? Would be nice to have seen temperature test results for both the trunk, and engine bay. Overall great DYI.

@@GhostSpeedShop gave me ideas for convertible. Idk if the temps are the same to start cuz the convertible top kinda folds up partially right there between the engine and the trunk. Gotta see what I’m workin with

[@frankiebpr]

Thank you

[@GhostSpeedShop]

You're welcome

[@markhooper2]

That’s a good partial fix. Inside the trunk on the backside of the bumper there are two vents and they’re letting hot air in off of the exhaust pipes into the trunk area. Put some duct tape over the vents..

[@GhostSpeedShop]

I cut that part out of the video, but they don’t really make sense. Why did GM put them there? They don’t function as a positive pressure vent like they would in a front engine car so pointless imo. Good call on covering them, they are one way from the inside out.

[@markhooper2]

@@GhostSpeedShop I think they are there to allow air to escape the boot upon closing swiftly. This keeps the Delois from rebounding when slammed. Most people close it softly and let the latch draw it down. Keep up the cool videos.

[@GhostSpeedShop]

@@markhooper2 ah with the soft close though I’m not sure it’s possible to slam them. Thanks!

[@convair21]

Got a ZO6 and the frunk gets as hot as the trunk. Can the material be used in the front? Thanks for the info.

[@GhostSpeedShop]

I’m assuming so, that strange though. My guess is the son hitting the top is heating it up? Maybe insulate the bottom side of the frunk lid? Even the front brake ducts push air right past the trunk so I’m not sure what would cause it to heat up.

[@JohnMatthew1]

Thanks, did you do any measurements on before and after?

[@GhostSpeedShop]

I bought the sensors to do further testing but it’s winter now where I live and I won’t get accurate temps.

[@TechnoloG84]

Any idea by chance what the difference in temp is? I just got a c8 and I’m low key concerned if the car could handle a trip from Atlanta to NC

[@GhostSpeedShop]

I’ve heard it’s a 30 degree difference, I have the tools to measure them but need a bone stock coupe to compare to.

[@TechnoloG84]

@@GhostSpeedShop mine is bone stock, what tool do I need to let you know the temp?

@@TechnoloG84 you’d have to be local to me, but they are these Bluetooth temp sensors. I have something lined up, here in a couple of weeks.

[@ParagonPerformance]

Great video but why is the Maxton kit on the wall and not installed? 😭

[@GhostSpeedShop]

Because compared to other kits, it hangs low in awkward areas below the car rather than just outward from the car. It rubs on damn near everything. I only put it back on the car for shows at this point as driving the car with it installed is no fun.

[@ParagonPerformance]

@@GhostSpeedShop Are you lowered at all? We have no issues on the roads and are lowered 2"

[@steveng8314]

Can you do it on a HTC the same way?

[@GhostSpeedShop]

Yup

[@ProtectiveDadPranks]

You’re must be getting hot. I have the Eventuri Cold Air Intake with the clear cover and it doesn’t get hot at all. Good mod for those that feel they have this issue.

[@GhostSpeedShop]

Yeah, every time I look at that beautiful intake I just think of how that’s 1/8th of the cost of Forced induction for this platform. I messed up and dropped 5k on something for the car, should be in a video soon! 😅 but yeah, long term goal is FI

[@ProtectiveDadPranks]

@@GhostSpeedShop great video BTW. Atleast you chose red too lol

[@GhostSpeedShop]

@@ProtectiveDadPranks thanks, I was between this red and the darker one when I Spec'd the car out.

[@DavidJCarrell]

Just hoping that GM engineers weren’t relying upon that area as a heat transfer surface to evacuate heat from the engine bay. Seems unlikely, but there must be a reason as to why they didn’t spend $10 to eliminate the problem of hot trunks as delivered from the factory. That said, nothing worse than melted ice cream!

[@GhostSpeedShop]

God, that would be a terrible design if so.

[@badcholesterol]

That sounds like an idea so bad, that only a GM engineer would be willing to implement.

[@dcdanger6151]

I have a concern this may create more heat in the engine bay specifically around the air box and mass airflow sensor area. I just put any heat sensitive items on the passenger side floorboard or seat

[@MiguelCedenoLozano]

Your theory is unfortunately absolutely correct. What are the long term effects of restricting heat dissipation in such a critical area? The engine bay may overheat, more than it already does, and create far worse problems over time than having a hot trunk. This just seems like a natural consequence with mid-engine cars. Having storage in that area is already a convenience in utility that breaks the rules and, therefore, should be appreciated with its natural deficiencies in mind. Perhaps it went down like this: Chevy executives pitched that they needed a mid-engine car that has a trunk and is $65k. Chevy engineers said "That's not possible". Chevy executives replied "Make it happen". Corners had to be cut. It's Chevy after all. The unreliable company protected by the government whose CEO blatantly lied about being the number one EV manufacturer in the world about a year ago.

[@DavidJCarrell]

Yeah I’m thinking it might be easier just to get one of those soft-sided insulation ice chests and keep it in the trunk…that way engine heat can still transfer into the trunk but it won’t affect any cold food items. Probably wouldn’t even need ice as the cold food items would provide the cooling effect

[@davidcurrens9869]

What was temperature difference after install?

[@GhostSpeedShop]

I’m not sure but deodorant no longer melted in the trunk afterwards. It was difficult to get measurements because I didn’t take them before I insulated.

[@kevinjohnson-ig8uy]

so the intake air is absorbing allot of heat from the engine? So much for a cold air intake.

[@GhostSpeedShop]

It could be, but the air box material is a bit thicker than even the panel that goes into the trunk. I’ll bet the thickness insulated the air box pretty well. I’m sure enough airflow throw it helps keep it cool as well. I might need to test some shielding on the air box in the future to see if it makes a difference.

[@derekb5749]

Every intake is subject to the heat of an engine...CAI isn't cold air, it's cooler air. LOL.

[@bradmason8334]

Have u did an update to see how it works?

[@GhostSpeedShop]

There’s definitely a noticeable temperature difference in the items I place in the trunk. I’ll have a part 2 to this video out soon with the temp data

[@GhostSpeedShop]

Make sure you get grille guards for the front too!

[@georgek719]

Simple thermodynamics would say that the heat has to go somewhere. So if it's not dissipating through the trunk, it's staying in the engine department. To the detriment of the engine??

[@GhostSpeedShop]

This assumes that the engine isn’t designed to keep itself cool

[@joelpierce3940]

It’s necessary in Texas

[@GhostSpeedShop]

Understandable. I think most of the people who disagree must live in climates where it’s considerably cooler throughout the year.

[@HellcatM6]

Aren’t you now making your engine bay hotter?

[@GhostSpeedShop]

Potentially, but the fan will quick on if it’s anywhere near too hot

[@mikestrickland2707]

If someone's concerned about blocking heat from engine, put a small cooler or insulated bag for cold items and eliminate those concerns you have.

[@GhostSpeedShop]

Yes and no, some people throw suitcases back there and various things melt ie deodorants, toothpastes and medications. Owners shouldn’t have to unpack just to store their bags. This could have been and easy fix from the factory.

[@out2flip]

Now your engine is gonna over heat! Should of just left it alone.

[@GhostSpeedShop]

Show the world data that backs this statement up. There has been no recorded increase in engine temps.

[@biffbifford402]

Only takes me 10-12 minutes to get home from the grocery store, and it doesn’t effect the temperature of my food at all. Not even ice cream. This may be different for you if your drive is over a half hour long. Another thing you can do is put the cold items in the fronk and the rest of the groceries in the back.

[@GhostSpeedShop]

I keep the frunk fill of camera gear and cleaning supplies so there’s no room to throw stuff in there. But even on long trips if you throw your suitcase in the rear, your deodorant will melt.

[@GhostSpeedShop]

Also we live in Hawaii where it’s hot all of the time, so it’s extra toasty in the trunk.

[@williameger3229]

Just use the Frunk for cold items.

[@GhostSpeedShop]

Dang, never thought of that 😂

[@dagrinch8921]

I think this is a bad idea or GM would have done it. Seems to me you will be reflecting heat back into your air box causing heat soak to the airbox and a loss of power. If you need to carry groceries or something else that needs to remain cool, drive your other car.

[@GhostSpeedShop]

The airbox sees constant heat from the engine bay already. I think alot of people commenting negate the fact that the airbox is a very thick plastic that should be insulated enough from engine temps. Additionaly there is a constant flow of air through it that should stay cool. Unless anyone has data to state that IAT temps have risen after simply insulating their trunk, then I think the argument is bogus.

[@bluesmurf22]

because GM does everything correct no?

[@derekb5749]

The spot next to the exhaust gets hot? Get out.

[@GhostSpeedShop]

The heat is coming from the engine bay, not the exhaust. There’s plenty of heat shielding below the trunk, just not on the front side facing the engine.

[@gregorypryer5275]

what is with people,, its a trunk next to the engine ,,, of course it is going to get hot, and who cares if it does, no one is riding in there, and if you say oh my ice cream will melt,,, aaaaahhhh there is the frunk you know..... put the ice cream in there.. waste of time if you ask me, sorry just dont get it

[@GhostSpeedShop]

Then why even comment? Even things like deodorant melt in suitcases in the rear trunk.

[@puny-tinsucks5102]

that's not good, adding more heat to the intake where air goes in can make for a bad combustion cycle, it is well known the cooler the air the better the fuel burn

[@GhostSpeedShop]

well, yeah. I would argue that if anything, GM made sure the intake was drawing in cool air regardless.
