Who are you dealing with on that custom cam? Just FYI there are a few Comp grinds available that are turbo friendly. They were discussed in Turboforums.com
Schneider Racing Cams/Dougherty Racing Cams . if you can send me the link from turboforums.com that would be great . thanks .
The only off the shelf comp cam I've looked at is this one (see specs below). it's solid roller . I like to stick with a hyd roller . and one from their XFI line up ( XFI292 ) . I spoke to Comp and they suggested one of their custom grinds 230/230 @.050 .560 lift/1.5 114+2 .
