Interest, Hood Vent

[carsNskis]

Just get the seibon

Buying something and building something have different value to people. Anyone can buy your hood... not everyone can design and 3d print a unique item

The Seibon hood is nice looking, and good quality... but in my eyes the $40 plastic vent is WAY cooler #becausenerd

I took this pic with the other vent on just to show what is beneath it.

Also I plan to make a mold of a finished vent, so you wont have to worry about smooting it out.

So besides looks the primary benefit is letting heat out at that side of the turbo? How does one prevent water from rusting the engine components? We get a lot of road salt
and such by me.

wash your motor frequently and spray liberally with wd40 after a wash (and if you're that concerned you probably should already be doing)... Add a foam layer to reduce intake of water...?

I was reading other forums about that issue with road slats. Those with vented hoods mentioned no increase in salt getting into the engine bay than occurs naturally from the front or under the car. Some had pans to divert water away from sensitive items when the car is parked in heavy rain. I think my vent is already in a fairly safe location so i wasn't planning on adding a pan.


I would be somewhat concerned if UV damages the coolant reservoir or hoses.

The Seibon hood weighed less than half the OEM hood.

I never had a problem with salt entering the engine bay through the vent.

The vent significantly reduced engine bay heat.

Pretty neat. Bonus points for checking coolant level with the hood closed.

I am into plastic injection molding, molds are very expensive to get built, and piece price may also be expensive. I don't think you would be able to sell enough for a return, PM me if you would like any more information.

Less than half! Holy smokes. Way better than I thought. This is the thread I was remembering (incorrectly).

Hmm, I think their coolant relocation might be useful.

4lbs... That's like 16 quarter pounders bro #somuchweightsaves #racecar

Mmmm quarter pounders...

---------------------------------

Llia, it would be fun to see how much heat is extracting out of the vent by getting one of those cheap indoor/outdoor thermometers with the probe and tape the probe above the vent. I think you can find them for around $10 to $20. similar to the pic below. Great work!

I just might do that. Thanks

I just ordered two so that I can film two different locations. They were fairly cheap and had USB power cables which should work well with a dual USB outlet adapter.

Yes, I've noticed how expensive it is. I also looked into small quantity 3D prints in high quality ABS from other companies. Going that route I would have to sell at $260 a vent to break even.

Still I am hopeful that my local printer person can provide me with reliable parts that I can sell for under $100. The testing continues. Have yet to run on a hot day with all this rain so I can't see if it will warp or not. After a few runs I want to fill in the grooves with modeling putty as filing might not be the best option. Then coat with high temp paint. I didn't coat before installing the vent to keep a clean mating surface for the epoxy.

 

[nickalltogether]

Glass point for ABS is just a little over 100 celcius, so as long as your hood isn't literally boiling hot you may be alright.

 

[RMinNJ]

I think the hood vents..this or seibon are really neat. I only think the car makers don't put them on because the cheap engine components are not resilient to rain and such. Or they want the heat in the engine bay?

 

[Llia]

Too much cooling in the winter isn't good. May have to put a cover on the vent then. Not sure why car makers exclude vents. Even small ones. I would think it's more esthetics. Easier to sell a blank slate.

Chevy uses hood vents in some of its upgraded Corvette and Camaro lines, where performance is paramount and fuel mpg less important.

I had the Seibon on the Sonic RS for 3.5 years with no deterioration to the engine bay components. Parking in the driveway as the Corvair uses the garage, so exposure to Michigan weather conditions was the norm.

the seibon vents really work

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
