Anyone running 9:0.1 compression ?
I'd like to know what the map sensor vacuum reading is at idle on a engine with a similar set up as mine.
I'm using CP pistons 9:0.1 compression with stock cams I'm getting between .48 ~ .52 BAR

Have a look here >>>>> http://www.gregsengine.com/using-a-vacuum-gauge.html
Convert .48 to .52 BAR to inches of mercury. You're currently around 14 to 15 HG which is below what you want. Could indicate vacuum leak or ring issues. |
