Supercharged Camira..

Craig and Adam\’s attempt at adding an SC12 to a JE Camira wagon

DIY Boost guage..

Posted by superchargedcamira on June 21, 2006

As you have probably guessed we are all about DIY here. We are going to make our own boost guage measuring the voltage output from the 2 Bar MAP sensor. Anything above 2.5 volts will be considered boost and can be tracked accordingly via a chip called the LM3914. It has 10 LED outputs that will light up when certain voltages are reached. Here is the prototype board Greg is making for us to house the chip and the LEDs. If you want more information on how it works or how we are going to get the signal from the MAP sensor, drop us a line. We will show you what it looks like when we actually do it but for now its just an idea.

  1. You guys are really up for the DIY stuff are you.

    You should try and get a chip that outputs a smooth signal that a mechanical gauge can read and display like it were a real boost gauge.

    Of course, on the other hand, you could just wire up LEDS and then you know when the last one turns on the engine will blow 🙂

  2. C’mon Mark, you think it will blow at the end one? im thinking sooner! hehe.. the last one is 1 bar which is 14.7 psi. Id like to see a stock n/a engine handle that.

  3. Haha yeah i’d love to see a 1bar Camira.

    Talk about sleeper! 🙂
