Afterburner Posted June 28, 2008 Report Share Posted June 28, 2008 I saw a video somewhere on here or youtube showing someone revving their engine in neutral and the boost gauge moving up as the RPM's came up as well as hearing the sc spinning up. My car only shows boost when I'm driving but not when I rev the engine in neutral. How does that work? Just curious. Link to comment Share on other sites More sharing options...

You need the resistance against the engine through the driveshaft. Link to comment Share on other sites More sharing options...

It jumps up to about 8psi if I am just revving the engine in neutral. Just one of many things that I haven't gotten around to doing yet. Link to comment Share on other sites More sharing options...
