Rear wheel ports

[Jinba ittai]

Wait, we’re talking about those horizontal slats? I don’t have my car in front of me, but I pointed a light in there before and I thought they were blind holes, not connecting through to anything. Maybe I’m wrong. I was just against increasing the hole to the wheel well from what was designed in the wind tunnel.

I initially also thought those may be ventilation slats for the engine bay. But looking at my car and going through old pictures I don’t really see how much can flow out of there.

The slats sit right up against the fender liner. Only the inside corner of them is open to behind the liner. And if you peek through them you can see the corner of the trunk. The trunk does a sharp 90 towards the chassis. There isn’t a direct path from the engine bay to those slats. Fender liner sits right up against the trunk and chasis so not much room for air to flow either.

This is what it looks like behind the fender liner.

That's great picture, nice to see all the drilled aluminum.

Think what Kitkit is saying their may be a bit of negative pressure created as air passes through the port from the wheel well. Which may be pulling air from between the liner and potentially some of the air from engine compartment area. From your picture the coolant tank is about 2 ft away and heat rises, not sure if those small slits would be able produce enough negative pressure to pull hot air from that large volume of space; which isn't sealed up tight.

Was the liner easy to pull out? Looks like once the liner is out the port is probably easy to push out. What do the tabs on the Port attached to? I don't recall seeing any fasteners around the Port in the liner when I peered in last.

The rear vent without a louver is present in the Evora GT, the 430GT, the Exige Cup 380 and 430, as well as the Evija and Eletre. Therefore, I don’t believe it will be an issue.

not sure that logic follows from other car models/designs, but I think your conclusion is correct.

Yeah, I understand the concept and thought same. But after looking at the actual car, the path from the engine bay to the slats behind the fender liner is so restrictive that you’d need ALOT of negative pressure to effectively pull heat. But then again, I’m just a guy on the internet who doesn’t have the credentials to say if that’s really true or not.

Yeah the liner is really easy to remove. Bunch of clips and a couple of bolts.

The tabs around the open portion of the vent are used to attach it to the fender liner. It uses 3 Christmas tree clips. I assume tabs more will need to be added to the top if the port is enlarged so the fender liner is not flapping around.

Perfect.

With the vents being a controversial topic and I'm personally unsure of specific purpose, I just asked Aeries if they are able to easily add two small slits to the top interior of the port. In a inconspicuous spot to try and mimic original slits.

They just sent new pictures of the mold. Interior wheel well port appears much big and should provide a decent view of the rear tires ! (Ports on Evija look great)

Thoughts - - Yes / No ?

I imagine more tabs in these locations would be needed so you can secure the liner.
