Hood Vents

[Cspencer]

Curious... I know they're not quite over the turbo area where most of the heat is generated, but has anybody just thought cutting vents where the 4 “recessed holes” are in the skeleton then place mesh in the open area? Would this help in any way?

Yeah, the OP thought of this idea on the first page of this thread. When done correctly (think louvers and creating a low pressure zone for them to extract air) they could help. There are two ways to look at venting though, the first is by simply removing hot air out of the engine bay to reduce heatsoak and second is to focus on specifically pulling air out from behind the radiator which is right next to the turbo. Those side vents being a little further back would mostly help with the former, imo. Heatsoak, while an issue on these cars, isn't the big issue, it's overheating from water temps getting too high. A properly designed vent above the turbo/right behind and above the radiator is where you'll see the most effectiveness against overheating.

I was referring to the grille part of the hood scoop, not the front grille. ?

And @Learn2turn , your version is actually letting air in and creating a high pressure zone in your engine bay, thereby decreasing how well your radiator works. Sure, you'll see heat radiate out of it from a stop, but it's not pulling hot air out at speed.

@JESFromASC 's design is theoretically a little better since the entire area isn't opened up and the scoop still feeds through the aluminum air duct and out the fenders.

Your assumption is incorrect, air does escape at speed and my scoop also still allows air to the duct. (which effectively goes nowhere)
I have also opened other engine bay air flow outlets, reducing pressure and enhancing air movement. Car stays cooler after mods, used to suffer heatsoak before.

Yes it would help. It would be tough to make it look nice though.

If the duct is still in place then I can see some air escaping then getting caught back into the scoop then escaping through the duct, but hot air is not just escaping straight out of the vent at speed. And yeah, if you have other airflow mods then I'm not surprised you're seeing less heatsoak.

Yes, I believe it is a turbulent tumble in that area. I may change it in the future but for now it does well enough with the bumper vents opened, cowl venting and belly pan removed to negate the heat.

I do have more tricks up my sleeve including an extra Ebay grille to mod and install and complete lack of fear when it comes to cutting the car up.

Summer is coming...

wish there was something like the Kamanari hoods for the WRX available

If you're looking for a similar concept, seibon has a hood for the base civic (you'd just have to relocate the hood latch to make it match the R)

This thread has me thinking of some how getting a hold or making vents that open and shut electronically...... Im always looking for a new project. any thoughts?

I'd probably start with a door or window actuator. They usually generate a good amount of force with low(er) current.

Found two hoods, Not sure if eaither are correct fit for Non SI sedan. i gather from the forum i would have relocate latch, but Im leaning towards the black one A: for Price B: I like the cut.
any thoughts?
which one would you pick?

Thats brilliant. I could run a line to cabin and figure out placement, easy enough, until i start the job, Then thing go array.... lol but Im gonna try it.
