The trays are held in place by 4 studs that are attached to the vent frame. Attaching/Removing the trays is very simple.

What steve said....no water issues

I will definitely be choosing this mod over an Aftermarket hood, and feel confident that it will come out great!

nice

Ok Just watched that video and sorry I am not convinced about the water deferrment take that cup and replace it with a five gallon bucket and you get the type of rain I deal with and drive with here in south florida. And there is a large following of us in the region so as nice as it is my car lives outside and unprotected most of the time So unless you can find modify it to take rediculous amounts of rain water I wont be in the market and I will say that I am impressed with its functionality and purpose but the rain is the reason why I still have a stock hood. Sucks to be me..

Lets try to take a look at this issue by the numbers. If anyone is interested in the math behind the numbers I use below let me know, but I don't want to confuse the point I'm trying to make here.

The splash trays will contain and expel more water than will enter the HEX Vent ports during even the most severe rain storm. For details on that claim, continue reading.

First a couple key metrics on the splash trays. The volume, for one, is 24 cubic inches and it's drain orifice will expel water at a rate of 0.25 cubic inches per second, or 900 cubic inches per hour.

On an average day during peak rain month (August) in Miami, the rainfall is measured to be 0.29". In terms of water volume captured by a typical rain gauge, that's 0.141 cubic inches. So, in a 24-hour period the rain gauge captures 0.141 cubic inches of water. The HEX Vent opening is 47% larger than the opening on a typical rain gauge. So we can assume 47% more water will enter, which makes the average volume entering them, in a 24 hour period, in Miami, 0.207 cubic inches.

It would take over 10 days for the trays to overflow even if they didn't have drain orifices. Moreover, it would take less than a second to drain the rainwater that would enter the HEX Vents on an average peak rain season day in Miami.

Finally, let's assume all the rain for the peak month in Miami, 8.63", fell in one hour. That's a rain gauge volume of 4.2 cubic-inches, and a HEX Vent volume of 6.2 cubic inches. The splash trays can drain that volume of water in 20.8 seconds.

Now all we need is a damn blackboard so we can check out these equations!! Brilliant Professor!

First of all so everyone knows,I absolutely LOVE my Hex Vents and was one of the first pre-order consumers.

This is truly a TOP quality product and have posted here on various threads spreading the word.

What people have to realize is that if you CUT holes in your hood you no longer have a waterproof hood over your engine.Water resistant,yes,Water proof,No.

That being said,I chose to deal with the side effects of cutting holes in my hood as my car is a weekend garage queen.The engineering calculations above in theory work but but don't expect your engine compartment to remain dry,It does not.

Don't lets this keep anyone from enjoying the benefits of this great product,just be aware of the permanent changes made.To some people it is not an issue if the engine gets a little wet especially with the stock engine cover.

For some folks it will matter a lot for reasons like water spots,supercharger belt slip,billet valve covers and other under hood pretty things.

The only way to effectively deter water entry would negate the purpose of the Vents in the first place.....Vent the heat through an opening

Now I have tried several different ways to utilize the provided splash trays to keep ALL the water off my engine with no success.The water dumps rite on top of the power steering belt.I added tubes to direct it away.I added 2 tubes.I tilted the trays so they were level when the hood was closed.Nothing got all the water as the water overflowed the sides of the tray because the walls are about a 1/4" tall.

The trays would have to be so large beyond the edge of the opening to catch all the water that effective venting would be lost as well as clearance issues.

Steve did a great job with this compromised sized splash tray..actually all he could do.

Even when washing the car and rinsing very lightly residual water gets past the trays.

I finally made external covers and that solved the problem completely....Water PROOF when I want to be and FULL venting when I
want it.There are pics of them posted around here.

Just wanted to share the results on my real world experiments and would recommend these to anyone.

I wanted to chime in on this as well. I have had some minor issues with the trays and clearance issues the whipple, but for the most part the rain has not been a factor and I have been in some down pours (it's a DD). The trays do a pretty good job of deflecting the water, but it does still splash/slosh around a bit. A set of rotofab coil covers can negate this and make everything look better in the process. . The only real problem for me has been the drain pours right on top of the whipple pulley and belt which can cause slipping. I like 67motorcat have been trying tubes and hoses to route the water away with out much luck, but I think I am going to ask Steve if he can make me a tray with the drain port on the side of the corner instead of the front. This should get the water off the pulley.

Lets not confuse the real purpose of these things is to get the heat out and they do that extremely well. I will take a little water splash and some modifiying in return for extending the life of the SC and motor any day.

[Steve@HPE]

SSlim....thanks for the comments. We just made it back from the Fest and after having talked with many new and existing customers I've decided to improve the splash tray design a bit. Since maximum heat extraction and water protection are opposing design criteria, the new design will likely be focused on enabling the owner to quickly open/close slots on the trays or allow for quick attach/detach of the trays. I'll solicit feedback from each iteration of the design from those of you that are interested in participating.

It was great meeting those of you that stopped by our booth at the Fest!

[zkdreads]

when will this new design come out? the only thing i can thing of is like an airfreshner vent. when you want the airfreshner to smell good u turn/open the vent when your not using it you close the vent. if this was some how incorporated on the bottom side



kinda like this one. you turn the lil knob thing and it close the vent so the smell wont come out. hopefully u get what im saying lol

[Ringo]

I think these are well made, and the videos and install help looks top notch. But I'm not a fan. If I were to do a vent I'd go with the ACS version.

I did both, and let me just say. The hex vent finishs first in every way possible. Quality, craftsmanship, install, and function.
