Interest, Hood Vent

[laborsmith]

Also, I would discard the hood blanket since its two goals are to keep heat and sound in the engine bay to "improve" mpg and provide a quiet ride. A hood vent would compromise both goals.

I want to leave mine on. I feel It protects the paint too.

To each there own, the hoof bracket does not really do that much tbh. Using the thermal camera the hottest spot of the carbon hood is still the vents. The hoof itself is barely warm

couldn't you cut a sheet uni-foam to act as a waterproof filter to ease the worries of water/salt ect?

BTW this is awesome, glad to see people thinking outside the box!

That would make sense. Carbon has different conductivity than metal hoods.

Not wrong!

I'll try and get a thermal of one of my other Sonic's, now in curious

I like this idea, but I think adding a few more vents like you did will look better. Very interested to see where this goes

A few more tweaks to the design. I will offer a second vent mirroring the first because a few are asking for the other side. Probably will Photoshop it onto my car. I like the asymmetry. My car smells like shrimp all of a sudden.

Centered, much better IMO

While the holes, and the 3D printer bed size force me to make left and right half. I can make a center piece to make them look like one... or not. just running it by y'all

Ok, I am really liking these. Both with the center piece and without, these look good. The passenger side vent seems like it would vent more heat than the drivers side, what with the turbo over there, wouldn't it?

I like the 2 piece look better. I would think there is heat on both sides of the turbo up there..

would like to see someone test one in a canadian winter . also id like to see if ur mpg changes with the vents in

I am skeptical to say it did even though it did. I was around 30-32mpg before and 34-35 after. However the weather has changes and it's cooler in the mornings now, so I'm not sure.

I think they are too close to make much of a difference when moving. The air moves around, mixes, then vent out. I feel it would be the same unless you are sitting still.

Wouldn't you want the vents as close to the radiator fans as possible? So like in between the fan(s) and turbo?

One of the vent design considerations Llia has is to not chop up the supporting structure under the hood.

Meh don't be a *****, the hood isn't gonna bend. I mean if it's there then some ducting from the fan going through there wouldn't be too bad of an idea

The air moving over the top of the hood and vents will create vacuum, drawing the air pushing through the radiator and intercooler out. The location a few inches forward/back won't really change much.

Most functional hood vents do have something under the hood directing air but these should still be effective.

Just get the seibon, it's not that expensive and you have the weight savings. I love mine

Screw the Seibon! Tell me about those flares! Did they involve any fabrication? Or just riveting them on?

 

[JesusTheAgnostic]

I like the look of the two vents but I don't quite like the way they're positioned. I think they would look better rotated 180 degrees so the corners point upwards. Though I understand that you chose that spot to avoid cutting up under the hood. Still really cool though!
