bugblatterbeast Posted July 27, 2008 Share Posted July 27, 2008 During the process of debugging a boost control issue I made some measurements of the stock BPV. Here are the stats: valve preload 23.4 lbs valve diameter 1 inch actuator diameter ~2 inches (had to estimate this one as I'm not near the office where I could x-ray the thing) assuming no pressure loss between the BPV location and the spot where the skinny hose is connected, the cracking pressure is 29.8psi assuming 1 psi drop between the two locations the cracking pressure is 25.8 psi with the pressure reference line disconnected, the cracking pressure is 5.96 psi Link to comment Share on other sites More sharing options...
