There are a few ways you could try and do this. I think the simplest solution would be to design a separate module that could be hooked up to the output of the stereo. The 2-way radio would plug into this unit and would control the volume of the stereo. If a call came in on the radio then the stereo would be shut off and the radio would be played on the speakers. Seems like a lot of work and you are kind of reinventing the wheel. If the bluetooth kit is a separate module you could try and adapt it to your design. But if the bluetooth system is built into the stereo you could have a hard time getting everything working properly. Oooo another idea.... If the stereo has a aux input that you are not using, you could plug the radio in there and design a circuit to automatically switch over when a call came. That seems like the best idea. Depending on how the different systems are working it could still be fairly complicated. Keep us updated on this if you try and make it work. I am a Electrical Engineering student and can lend any help you want.

lol... common im trying to give the thread back

This thread got way off topic. I'm sorry... my bad Back to the original topic. This car is absolutely beautiful, I was at the MSA nationals and I somehow managed to just pass over your car. I think its cause I already have pictures of it on my computer I LOVE the intake manifold, looks like you have put a lot of work into this engine. I hope I get another chance to see this piece of work, it is going to have a huge influence on my turbo build.

I am not completely sure on this now but it makes sense to me that if a material is black in the visible spectrum it would also be absorbed by the infrared spectrum which is very close to the visible spectrum. I am again speaking in generalities, but i think they apply to the situation. If you were to go to the store and buy high temperature black paint I would assume that it would absorb more IR radiation than a similiar paint in a white color. You are right though, just because something is black does not mean it is not reflecting IR light, and visa versa. A material white in color may actually be absorbing IR light.I guess to be sure you were using a correct coating you would have to know more about the actual coating... I love this stuff... lol

I would not feel comfortable standing under that. I live in earthquake country.

That is wrong, I just noticed that you said that. Why do you think that the solar water heaters are coated in black. They are meant to absorb all of the energy possible from the sun. This includes IR light and UV light. Both of which are affected by the color of a coating. Light is light, if the wavelength is such that it wont pass through the object than the color will dictate much of the reflectivity.

That conversation about color of intake manifold was here, and there wasn't really a consensus. My opinion is there will be an effect but it may not be noticeable. Any kind of radiated heat will be reflected by a white color and absorbed by a dark color (This is a huge generalization, it also has to do with the properties of the material). The light does not have to be in the visible spectrum, visible light is a very small part of the spectrum of light. The wavelength of light radiated by an object is dependant on the heat of the object. The temperature of a human body is such that the light radiated will be mostly in the infrared spectrum. This is why IR goggles allow you to see the heat radiated by a person. The temperature of the sun means that the radiated energy peaks in the visible range. There is nothing special about infrared light that means heat. Its just that the shape of the black body spectrum means that almost anything which radiates energy will radiate some of it in the IR range. Blackbody radiation curve: http://en.wikipedia.org/wiki/Black_body A reflective coating on the underside of an intake manifold will keep the temperature down. The only way that you could find out if it is noticeable is by testing. I think that a heat shield would accomplish the same effect and would actually work better. The aluminum will reflect the heat from the exhaust manifold and will also limit the heat transfer due to convection. Also the aluminum will have a low emmisivity and so wont radiate as much heat as the exhaust manifold will. I would think that a simple piece of aluminum or steel sheeting mounted to the bottom of the intake manifold could have a huge effect on the temperature of manifold. Mounting it to the exhuast manifold would have very little effect because it would just heat up as the exhaust temperatures rise.

I liked the cell phone... lol I had to do one of those for a materials class, funnest project I ever had.

One of the best looking z's out there. That paint is beautiful!

What is your backround in electronics, is this stuff all self taught? I am an EE student at Cal Poly (graduating in June!!!) and I am just curious where your experience comes from for this kind of project. What kind of system is this going to be, are you going to be programming in VHDL, assembler, C... What kind of microprocessor are you going to do? This seems like a huge undertaking, sounds like a lot of fun though.

The CPS on my nissan pathfinder is mounted at the top of the transmission bellhousing. I know because we broke it when we pulled the transmission. The only way you could get to it is by pulling the transmission, even then you cant see it until you have already broken it... lol. I am not really sure what it would be for on your car. On some cars a CPS is used to electronically control the spark instead of a distributor, but I really dont think that is true on your car. The spark advance may be controlled by the CPS which could cause some running problems, not really sure though. As far as replacing it yourself, it totally depends on where it is. No matter what it is not a technical job. You just have to find it, pull out the old one, and plug in the new one. Really shouldn't be too hard, but it might be a huge PITA to even get access to it.

I have heard about hunting boar with dogs and a knife. There is lots of boar hunting in this area.

I have a good friend who hunts boar with a long bow. Its not even a compound bow (which is a popular boar hunting tool), its the good old fashioned simple bow. He brings home boar all the time too!!

I am a huge fan of the nissan pathfinder. We have a 97 with a V6 in it and it is so much fun to drive. Makes a beautiful noise too. Gas mileage isnt the best but that could be a result of an evap problem that our pathy has. Pathfinder is a really good size, not too big. Really fun for basic offroading. I have taken it to Pismo a couple of times, forded some rivers, and taken it on a couple of trails. It can take almost anything we throw at it but its still a comfortable cruiser with plenty of power.

Nice find!!! They look like they fit really well. How is the height? Did it bring your head any closer to the roof?

As was previously stated, there are three kinds of heat transfer: radiation, conduction, and convection. I would argue purely from a theoretical standpoint that this could have a noticeable effect on the temperature of the intake manifold. Whether it is enough to notice a change in the air temps I dont know. The exhaust is going to get hot enough to radiate a large amount of heat energy, a heat shield will reflect most of this heat but the exhaust manifold (or headers) is so close to the intake manifold that I would bet there is a large amount of radiative heat transfer from the exhaust to the intake manifold.

I used to play a lot more but my laptop is slowly starting to bite the dust. I even had admin on a few servers, thats when it gets really fun. Unfortuanately when I play now i am consistently at 10 fps. Kinda hard to play like that.

Hey Turbo Meister, I met you at the end of the day on Sunday. I have to say that your car was one of the highlights of the show for me. Hearing that engine was amazing, and thanks for taking the time to talk to me about that beautiful machine. I also took a glance at your videos (i actually downloaded all of them to show to friends... lol). Do you have any of you running the quarter? I want to see more of this monster. Congrats on having such a beautiful piece of work!! I hope to see you there next year.
