I take it, that the flat section of the port must remain... Well I guess that the port will not be drilled out, but will now be hand ported (Enlarged and edges smoothed).... : Link to comment Share on other sites More sharing options...

I enlarged the wastegate hole and ported the housing today. I have taken the housing to a local machinist to mill the lip off the housing and remove the interferance material where te shaft goes through. This will create a better seal and allow the Folapper to be set into the correct position. All up, it has taken around 2 hours of me just dawdling along. I have taken Rattlers advice and shaped ported the housing similar to getting your heads ported. This will minimise turbelence in the housing and increase the flow through the wastegate.... I have sent the to a machinist to mill the lip off and remove the interference material from around the shaft where it comes through the housing. This will allow for a larger port and better seating of the flapper. I will post up some pics of the porting when I get it back later in the week...

I decided to get the raised factory lip removed and we machined the housing so that the flapper will seat level with the housing. Unfortunately it is a bit too late for some pics and it is overcast also.. So it has made it impossiblr to get any good shots of the porting and machining.. I will post some up tomorrow...

I will make it clear now, that I am no expert in this field. I ported the housing without seeking professional advice. Only Rattler (Thanks Bud) has been kind enough to post some comments with advice.. I have used my own reasoning and ideas on it's flow characteristics. I am hoping that someone with some knowledge will comment and correct me if I have made any errors... I have made a photbucket folder... I know that some of the pics are not the best quality. But you will get an inkling of what I have done...Porting Pics Link to comment Share on other sites More sharing options...
