So about a 16% improvement.
Watch out for gear oil blowing back up the air line and out the air compressor inlet. If that happens then the large diameter seal on the ARB either has a twist in it or a small tear. This is a know issue and ARB did change the seal design several years ago. I need to tear into mine and fix it.
