Gang, the new engine setup I have is a GT2860RS turbo with a Begi divorced WG downpipe. The WG flapper does not fully open because it contacts the wg tube. It opens ~ 3/4 of the way, which is better than on my previous setup with my GT2560 and Begi divorced WG downpipe. I had to grind the other DP significantly in order for the flapper to not get wedged open, but even then I could only open it about the same as this new setup and I did experience boost creep.
Will this cause boost creep at higher boost levels? pictures: http://home.comcast.net/~mcoupedude/BegiDP/BegiDP_wg-partialOpen.jpg http://home.comcast.net/~mcoupedude/BegiDP/BegiDP_wg-partialOpen2.jpg http://home.comcast.net/~mcoupedude/BegiDP/WG-partialOpen.jpg http://home.comcast.net/~mcoupedude/BegiDP/WG-wideOpen.jpg thanks, Mike
