Whats The Difference, Please Help... What is the difference between mechanical and electrical gauges for the pillar pods, i am looking on JEGS trying to get my boyfriend some 2 1/16'' gauges for the pillar pod i bought, and i might sound stupid or it might be a stupid question but please can someone help me out on what the difference is!!! Thank you..... oh and which would be better and more accurate, thanks!!! and why are the fuel pressure gauges so much more expensive! :confused: :devil: |
Re: Whats The Difference, Please Help... A mechanical gauge gets its reading by actually taking a measurement of whatever is being measured AT THE GAUGE itself. For example, if you are using a mechanical oil pressure gauge, a tube runs from your engine to the back of the gauge. This tube fills with oil and gives the gauge a pressure reading. The same is true for a mechanical oil temperature gauge. Using mechanical gauges, as you can tell, involves running tubes through your firewall and to the engine or whatever is being monitored. It is for this reason that there are no mechanical Fuel Pressure gauges - it would be pretty stupid to have a tube of gasoline running into your dashboard! Electrical gauges, on the other hand, use an electrical sending unit at the source of whatever is being measured and send a signal across an electrical wire to a processor in the gauge, that converts the signal to a reading. Usually an electrical sender uses differences in resistance (ohms) to send the signal to the gauge. Installing an electrical gauge involves installing a sender at the source (like oil pressure) and snaking an 18 gauge wire through the firewall to the back of the gauge. Electrical gauges also require tapping into your car's 12 volt power to "power" the gauge processor. There are also various grounds that might be necessary to ensure a clean, closed signal. |
Re: Whats The Difference, Please Help... why are the fuel pressure gauges so much more expensive? It is because of the sending unit. ;) |
Re: Whats The Difference, Please Help... so i should probably get them installed professionally then.... dont want to **** anything up!!! so i am definatly going to get him electrical...... anybody know of any white face gauges that are digital??? i need white faces and digital reading, that would be sharp as hell! thanks toxic for the info!! |

Re: Whats The Difference, Please Help... yea but the man is being picky, i saw those earlier today!! have you ever seen any digital ones that have white face gauges? |
Re: Whats The Difference, Please Help... http://www.dakotadigital.com/products.cfm?Category=131 I can't find white face digital gauges. I think you need a black background for digital gauges. http://www.click-smilie.de/sammlung/...smiley-013.gif |

Re: Whats The Difference, Please Help... http://www.clay-magic.com/ and a good wax. I use https://www3.autozone.com/images/pro...rg-7016003.jpg Get him a bunch of Mobil 1 and filters. A ported TB. New TSP carbon fiber lid....... :D |
Re: Whats The Difference, Please Help... I know I've seen a white faced A/F ratio gauge... but as far as mech gauges go, there are mechanical fuel gauges. It just involves a diaghragm in the line that transfers the fuel pressure into a line of anti-freeze/water that then goes to the gauge. If I can find that white faced digital A/F guage, I'll post up a link... it definately looks :pimp: |
Re: Whats The Difference, Please Help... thank you! |
Re: Whats The Difference, Please Help... I've never seen a white face digital guage, good luck finding one. |
Re: Whats The Difference, Please Help... yea i need it! i haven't seen 1 either |
Re: Whats The Difference, Please Help... Boy Josh with all that gauge knowledge youd think you stare at gauges in a plant all day... |
