BTW, not dissing your cover or estimate pricing...just thinking about the weight and can't remember any items adding to ~200 lbs.


I can't find that comment on the tapatalk app. Not sure if it was deleted but I was trying to say ~20lbs. If I wrote ~200lbs that is definitely a typo lol. The engine cover is 7lbs, sound carpet is like 6lbs and self was another 6lbs.

dghii 01-19-2014 07:45 PM

Heck. I might have misread the quote. 20lbs sound about right.

What will help me bring the price down is if I can purchase wholesale sheets of the plexiglass rather than commercial sized ones that I have to cut down and subsequently waste a lot of material. If I can get an idea of how many people would be interested in the cover, I can start considering a final price. I'll also update this comment with an initial ballpark price (it will be the higher end of what I will offer and it will go down as I can get parts in bulk)

EDIT: ballpark will be $250-$300

EDIT: the setup saves you ~20lbs, if that means anything to anyone.

My bad...really need glasses!

Beat to the punch.

epapp 01-20-2014 12:48 AM

I think you said YOLO at one point in reference to this engine cover. Just for that, I think I'm required to order 10 minimum.

When we waited in Taco Bell drive through line, the cover warmed up, BUT it wasn't hot. The thermometer readings will put this concern to rest.

The sound increased, because the heavy sound and heat damping carpet was removed. The sound level equivalent would be to remove the rear shelf and remove the carpet cover while leaving the engine hatch cover sealed. Shehadehd's engine cover seals the compartment just like the oem hatch cover.

Would your kit come with the lights? I need me some of those

I have started saving money for a slightly larger project on my boxster, I think I found a Winner! Keep us updated on the temps, living in the Deep South with lots of expected city traffic may be a problem haha.

It's pretty thick and with the engine fan on, it stays pretty cool. I think temperatures need to be north of 200 degrees before any forming takes place.

I just bought some stick on thermometers that I'm gonna attach to both sides of the cover to see what the temperatures get to and if heat will be an issue. So in short, I haven't had that issue and I've put around 800 miles so far.

The gray tinted idea sounds pretty cool, like using really light window tint.

The Plexi will need a bit of a heat margin because after a hot Auto-X run and with the engine sitting after the car is off and the fan not running it could get quite a bit hotter in the engine compartment. Perhaps a plastic with a higher temp range. Lexan? Plexi softens at 210F and Lexan 257F

If you use the tint that you apply yourself then you will have that protective coating as well that you were considering for the engine side.

So if I get one of these I'll have to start carrying a feather duster in the trunk as well.
Not sure what the guys or wife will make of that when they see feathers in the trunk.
I'll just have to tell the guys that the french maid uses it to clean my engine bay
and the wife, that its a special surprise :cool:

Chuck W. 01-20-2014 06:54 AM

Evidently, this is not uncharted territory. I have never heard of it but there are a number of posting on Caymen owners doing this mod with great results. I am guessing they have worked out the material and heat issues. Below is a link to Google Imagines with a number of photos.

Thanks for the input. I'm trying to consider these situations but the weather right now doesn't really have the capability of taxing the plexiglass like you mentioned. One consideration is that the plexiglass does absorb and dissipate heat across its surface fairly efficiently. If I use a heat gun at 235 degrees or a bit hotter, the plexiglass never gets hot enough to form because it spreads the heat out and transfers it to the other side of the glass. As a result, I need to bend the plexiglass in a forming oven that heats the whole thing at once.

Lexan is in no doubt a more resilient plastic, I'm looking for both plexiglass and lexan as material sources. if I notice that the plexiglass gets to forming temps after hard drives like track days or A/X, I'll offer the cover in both lexan and plexiglass, depending on wether you plan on tracking with it or just daily driving.

I know high temp plexiglass exists which can withstand consistent temperatures near 300 degrees. I haven't found a local supplier of it though. I'll post test results to engine bay temperatures sometime this week or next to give you an idea of how the inside and outside surface of the plexiglass does under about 1 hour commute time with San Francisco/ Bay Area traffic

rp17 01-20-2014 08:51 AM

Without a doubt, this isn't new. Peeps been doing this on Caymans for a while. So worry not too much about the heat thing. Don't think those can fit a 987 Boxster though and definitely not a 986. I think they were priced ridiculously high also which I never even bothered looking into any further.

BYprodriver 01-20-2014 09:08 AM

How about a mod with dual payoff?

Heat reflecting gold foil. Makes engine look better & keeps intake air cooler.

Shehadehd 01-20-2014 09:42 AM

I'm going to start a new thread to track the ordering process for the covers.

Hardware: I've been able to find a source for all the hardware and I have a couple installation procedures that I think are simple, straightforward, and allow you to switch between the regular or clear engine cover without much work. I'll have a couple people test them to find the best one. I'm also working on find a way to offer the bolts and caps in chrome or any specific color that can match your car exterior, no guarantees though :).

Seals: I just ordered a bunch of different type of rubber seals intended for high-heat use and I'll be testing which one gives the tightest seal and best noise reduction.

Cover: As mentioned earlier, I'm still working on finding the best material to use and still keep costs down. I don't think I'll be going any thicker than quarter inch plastic because forming becomes increasingly difficult. I'm most likely going to offer both lexan and plexiglass covers; lexan will have to be a bit more because it needs to be cut and formed differently. Depending on how much demand there is I may be able to offer cover that are tinted in a particular color. This is only a plexiglass option. The tinting will be built into the plexiglass because I think any film applied might peel off under high temperature conditions. Examples

Shipping: I haven't worked out anything with shipping yet.

Porsche9 01-20-2014 10:16 AM

If you want to do some real high temp testing Phoenix is the place. In summer I regularly see temps on the I10 of 135 (ambient in the mid teens plus heat reflecting from the asphalt and all the cars immiting heat). I am sure the engine bay temps exceed anything you will see in the Bay Area. There a reason a number of manufacturers test here. Let me know if you want me to test.

particlewave 01-20-2014 10:40 AM

I'll beta test one for you...and I won't even charge you for it! :D

Seriously, I must have one in clear with multi-color lights (I like to change things up a lot) so hurry it up already!
It's been a day or two and I'm sick of waiting :(
What's the darn holdup?

:D :p

The engine compartment itself doesn't get any hotter because you went from wood, carpeting, etc to Lexan, but the passenger compartment may be a little warmer as the Lexan wont insulate as well as the OEM materials.
If the Lexan is warping or melting at the track or if that's a concern, can you use slightly thicker Lexan?

Shehadehd 01-20-2014 01:42 PM

Haha, I watched the gif before looking at who it was from... Now it makes sense lol. I've pinpointed a good source for plexiglass and even lexan so tonight I'm going to try and get things together to make a small batch order for the first set of prototypes. Also, I have to do some testing with the LEDs to make sure they work reliably with the engine temps they're subjected to. I'm sure I'm being overly cautious but the last thing I want is for someone to message me saying something failed.

Also, the LEDs are going to be socketed into the rear defroster switch to reduce the amount of wiring needed for the installation. Whoever orders leds can manually wire them to a separate switch if they wanted. I'm also in the process of adding a switcher at the junction where the rear defroster connector is. The goal would be to allow you to plug in both the rear defroster and LEDs into the plug and switch off the defroster or LEDs so that the dash switch will activate one of them or both depending in how you set it up.

The motivation for this was to keep power draw to a minimum but still allow you guys to retain defroster capability if needed.
This will probably be an optional add on since I don't want to wire the setup if I don't need to, e.g. You have a plastic soft top and no use for the defroster.

Awesome mod!
As long as it seals the compartment like the OEM cover (no fumes or heat inside) and it is "kinda" safe in a car accident...

I personally like the blue lighting, but would prefer AMBER just like the interior gauge lights.

Just another little idea: How about creating a see through plexi glas cover including a classic 356/911 chrome engine grille...that would be my favorite...
...oh pelicanparts are offering those...cool...hmmm...lets see:rolleyes:

These LEDs do continuous RGB coloring. Name it and it will do it. I didn't take a picture with Amber but I have this one.

who's going to offer painted manifolds like the custom speedster in the current Excellence mag?
oh, and if you need any cold weather testing....;)

When you get this working the way you want, I am definitely in on a buy :cheers:

With that being said, the noise is less than what you get with the top down or even the windows down. With the top up, you mostly hear the intake howl, the "whoosh" of the air rushing past the throttle body, and a small hum from the timing belt. In other words, I would say that the noise that comes through, is the noise that everybody tries to amplify by removing the snorkal. Of course, I'm biased though... epapp has ridden with me with the clear cover on so he can give you an objective critic on added noise. I'll also try to post sound clips comparing the two.

Yellow986S: I'm thinking of possibly selling a couple of these since I ended up making the equipment needed to mass produce them (like molds, heaters, frames, etc..) in the process of trying to get it right and have it fit with an OEM feel replicate dimensions. But don't expect them to cost an arm and a leg. Honestly, I think it would be cheaper for you guys too, because unless you have acrylic bending tools and a precise way to measure the engine cover in three dimensional space, it'll take a couple of tries (which with this size of glass is expensive) before getting it perfect. Also, the one in the pictures is also not perfect, but it's getting close. Butttt, with that being said, it depends on the demand for them as well. I also don't expect to be able to quit my job from the money I get and so I'm not going to price it that way; expect, hobby price... Just enough to let me do other DIY mods to the car.

And thank you all for the compliments!

Sounds awesome!
I am definitely interested in buying this once you have made a final product. I think it would look awesome if you painted the intake manifold or laid some carbon fiber over it. 2 Thumbs up!!

thstone 01-21-2014 06:58 AM

Just a suggestion - double check the grade of material that you plan to use; there are several grades and the forming temperature (when they start to become pliable) ranges from 185°F to 329°F.

epapp 01-21-2014 08:22 AM

Uh huh! Look who decided to use the rear defrost plug for power.

I seem to remember a certain someone naysaying the idea all the way home.

jmccjr 01-21-2014 07:27 PM

Great looking addition. A very cool concept indeed.

Shehadehd 01-22-2014 05:15 PM

So I've made my choice on two distributors for plexiglass and lexan and I'm getting some samples sent for cutting.

I've also located three sources for rubber sealing and I'll be testing each for heat resistance, sound deadening, aesthetics, and to make sure no fumes leak through.

The mounting method I'm using now requires you to swap out the OEM clip nuts for a different set that the bolts lock into better. I'm currently looking for a set of bolts that let me keep the original clip nuts without loosening on bumpy roads.

It will be at least a week until I get the samples I ordered and possibly a week more before I'm satisfied with the dimensions, seals, and hardware. I'll keep you all updated and probably get a formal count on who is interested so I can send out a batch order of plexiglass or lexan.

Porsche9 01-22-2014 05:54 PM

Thanks for the update.

Absolutely perfect.

AP328 01-26-2014 09:13 AM

I have only been a member of this site for a few days and I must say the innovation and expertise are just amazing. I don't know how I wasn't aware of this site previously. I have seen the mod on a Cayman and it looked fantastic.

Great work!!

I have done no modifications to my car since buying it new, but I would consider this. Do you know if the storage unit is difficult to remove? I assume this would all be reversible to stock if one decided to go that route for a concours event, correct?

Porsche9 01-26-2014 09:32 AM

AP328,

Removing the existing cover is easy. Once you done it once you can do it in about 2 minutes (do a search on this forum or Youtube). Having said that this mod is super easy to reverse when it is time to sell the car. Assuming the clear cover is in good shape I sure you could resell it to recoup some of your money.

I am usually very good about doing searches, but didn't in this case. I did a search and found several Youtube videos that showed the process, including the storage box removal. Thanks for the help. The whole process certainly appears reversible.

I was also looking at a Cayman site (HIP Design) that offers the clear engine covers for the Cayman and the painting of the intake manifolds (silver for the runners, read with white Porsche lettering at the top) looked great. HIP also offers a cover for their clear engine cover so that items can still be stored on top of the clear cover or one can simply protect that clear cover when there isn't a desire to show off the engine. Interesting.

Getting your intake manifold painted is almost a must to take full advantage of the clear engine cover. HIP's storage bin is pretty cool. I don't know if it's $300 cool though.

Since some have the Bose system and would rather keep it in, I'm looking at a way to let you guys put the rear self on the cover if needed. It would get rid of the engine view from the cabin. You should still be able to see the engine through the rear window with the top up.

Mark_T 01-26-2014 12:17 PM

A cover for the plexi is good. i'm wondering if this could be done in such away as the orginal cover would fit back over the plexi and then just be removed when wanting to show the engine? That's probably getting a bit complicated...
