    EGT...elec or mech?

    What is the advantage of getting an electrical EGT gauge as opposed to a mechanical one? Does it have something to do with wiring or tapping? As always, thanks in advance

    They make different kinds??

    I just installed my Blitz EGT gauge and it was electronic. Had to connect 4 wires to make it all work correctly. Really not all that hard to install.

    I'm really not concerned so much with the difficulty of the installation. I want to use this gauge, but it only comes in mechanical. I wanted to see if it would work just as well as an electric gauge.

    I dunno if you want hot exhaust gasses coming in the cabin. I don't even know how it would work?

    I can't believe HKS doesn't make any electrical gauges. I want them to match my indiglo gauges. Oh well, I suppose I'll just go with the Blitz BL gauges.

    Nobody routes hot gasses into the cabin. There is a probe to install in the exhaust manifold with wires leading to the cabin. The function of how the gauge provides its reading is the the "electronic / mechanical" aspect.

    Now, get somebody smarter than me to explain the difference between an electronic and a mechanical EGT gauge. I'm almost certain I know the difference but I'm not up to explaining this one except to say, the read out on the mechanical gauge is analog - a moving needle. The electronic gauge would probably include a digital read out and have no moving parts. In my mind, both are electronic devices of a sort.

    Wow. This is easy. There is absolutely NO SUCH THING as a mechanical EGT gauges. All of them ar thermocouples. WRXin' Who the he11 tried to sell you a mechanical EGT? Do you mean the display or something? That would be analog vs. digital.

    Here is a full listing.

    Thanks, Jim. I thought I was getting a little nuts when I read the "mechanical" EGT gauge stuff.

    If you clicked the link on th HKS page, they call the gauge "mechanical"!

    What the hell are they thinking?

    BTW, Joe, you have to press your forehaead against the hot gas. Like when you check a kid for fever. Hand's not sensitive enopugh.

    some companies have manual and electric gauges for fuel pressure, and for the manu. you have to run a fuel line into the cabin.

    Yeah, that link is what I was referring to. HKS makes a nice looking gauge, but it's mechanical. That's why I wanted to know the difference if any. So what do you guys think, go with the HKS or not? Again the link is in one of my posts up top.

    TeamShiftPoint -- yeah, I've heard horror stories of the oil line bursting and people having oil spills inside their cabins. I'll py the extra $$$ for n elec fuel pressure gauge
