I did some minor porting today and bumped the head up to about 255cfm at .450". The pitot still isn't working and I'm not going to get crazy with it until I can see what exactly the air is doing in there. So all I have done so far is fill some of the bottom of the port, enlarge the radius on shortside turn, alittle work on the guide and cleaned the port up some. It still has a long way to go.
