Made another trip to Otto's today to finish up on some tunning. Our initial dyno runs two weeks ago limited us to only 838 RWHP @ 26# boost due to fuel pump issue. After replacing the pump and fixing some minor wiring issues I made the trip back down to Otto's to hopefully get some big numbers. The day didn't start very well with some elusive missfiring issues we had from the week before. I was considering putting it back on the trailer but Otto pressed on to fix the issue. I have to say that Otto took the upmost care and detail in my car but at the same time knew how far to push it. So, after Otto fixed up my crank sensor issue, we were up and running with some clean runs. We made 917 HP at about 30#. We turned up the boost slowly and made a few more runs until we hit a maximum boost of about 35#. The car didn't pick up much power @ 928 RWHP. With only picking up 10 HP with a 10# boost increase is telling me that I am hitting some mechanical limitations. My best guess is that we may be into valve float and could use more spring.
I just want to say thanks to Otto for doing a great job on the tunning, troubleshooting, and just plain helping out on resolving the issues we were having. I can't forget about Bison(Brian) for the help he has given me. I think he is sneeking in my garage as I'm writing this with his own plans on changing the valve springs.
If I can figure out how to post the video than I will try and get it up here.
Edit: We were using XFI closed loop boost control with no CO2 to get these boost numbers !!
