So I decided to finally buy and install a boost gauge in the mini. I am getting severely worse MPG as I'm now addicted to watching the needle hit 15psi @ 7200rpm The install was fairly straight forward until it came to the wiring of the light bulb, in which case I have ZERO patience for hunting out a grey/red wire among ~50 other TINY wires in the wiring harness with hands the size of lunchboxes . But once you get the wiring done fire up the car, it all seems worth it! Anyways, take a look at the pics and let me know what you think, and if you have any questions about the install don't hesitate to ask!
its mechanical. and i used the $15 autometer 2 5/8" mounting cup (only need a longer screw to attach it back to the tach) and you can get these from summitracing.com
You guys do know that you can get the stock boost gauge out of an SRT-4 for cheap. They are an autometer 30/20 gauge.
Most Srt-4's have bigger turbos now & have switched to a 30/30 gauge (some need to read higher than that as well). You can find these in For Sale threads in a lot of Neon/SRT forums & on E-bay as well
