    glad to see you found/confirmed your leak.  you must have been burning some low-grade leaves otherwise you wouldnt have needed the water spritzer.

    You should see my garage. There are too many fire hazards to whip up a bonfire. I tried but I don't think I have any leaks except for the turbo cold side. (Video on instagram. Here soon.) Once my silicone dries up tomorrow I'll smoke the turbo side and see is she puff. #ifshesmokesshepokes

        Todd, TCD, came by the garage the other day and put my mind to ease about the leak.  Everything is a-ok!

        Now do I boost it up?!?  What to do...what to do...  If I do change the spring I'll out in a 20lbs one in there.

          check the compressor map.  I know absolutely nothing about turbos but, check the compressor map.

            I think we are in the same boat.

            Here is the map for my turbo.  This is a foreign language for me.  HELP!

              Looks like 2 Bar (29psi) would be my optimum boost for the turbo?  That's 14psi more than I'm at now. 

              Oh god if this is right this will be crazy!!

                I found this on you tube and this guy states you should consult the compressor map when choosing a turbo for you car. Anyway, I watched it and this guy knows what he is talking about.

                  That video was a great help.  Todd, TCD, picked out the perfect turbo for what I wanted to do with the car it looks like!  (I never doubted him!)

                  I'm thinking start with a 20-24psi spring in the wastegate and see how that works with the setup.

                  I emailed TRM to talk to them about fine tuning the tune.  I would like to get it dyno'd at the high boost to get the air/fuel ratios documented and have them take it from there.

                        On compressor maps, the y-axis is the pressure ratio which is (intended boost pressure + 14.7psi)/14.7psi.   so a pressure ratio of 2 equates to ~15psi boost pressure and a pressure ratio of 3 would be ~30psi  etc.

                        On the x-axis, the target horsepower can be approximated by multiplying the flowrate in lb/min by 10. so 40lb/min being about 400whp. You want to land in the middle of the highest efficiency island. 

                        TCD or anyone that isnt a total noob with turbos, please correct me and expound, I am here to learn.

                          I was not calculating my pressure ratio correctly. 20psi would put me at 2.3 PR and that puts me right in the honey hole for the turbo! Well, maybe I guess.

                              When the hood bulge is accentuated by those highlights and the headlights arent a focal point, it kind of looks like an E21.

                              You'd be tempted to think the E30 was made after it or something.

                                      Actually let me know how the vibration is.  Better yet, I need a ride when they are installed. 

                                      As for motivation. Get some warm clothes on, Get the jack out, put a stand on one side, Get your 12 or 13mm wrenches out, support the trans with the  jack, replace them, and be done with it in under 15 minutes. 

                                      I dare you.
