Auto Meter 5704 Phantom Mechanical Boost Gauge by Auto Meter

here is your phantom to boost pressure this is a mechanical gauge it's phantom number seven five zero four has a backlit display I'm currently in park but the vehicle is running so you're not going to see any pressure build I'll go ahead and put the car on the road and I'll splice it over so that you can see that and you can see it change I'll also do another splice where it's actually dark out and you'll be able to see the gauge when it's darker out as well alright so now that the car is moving a little bit we'll come into the throttle and you'll actually get to see the boost come up on the car and it's mechanical it's the only one of the gauges that I have it's mechanical so as we come up and then it drops right back down just to give you an idea of kind of what the cars doing when it's connected here's the phantom to boost pressure gauge and you'll see here I've got a blanket tossed
