Status as of 10/10/06, headed over to the machine shop Friday and pulled the spacer out to change the bore size. While we had it all torn apart we made some precise measurements on the inake and throttle body bore diameters. We then proceeded with making the changes to the drawing in solidWorks, created some new CNC code and reworked the spacer. I have now been running it about 4 days and can feel a bit more midrange power from the spacer mods which now has the bore matched to both Intake and Throttle body openings. The intake opening diameter was larger than the throttle body diameter so there is a nice outward taper to the spacer bore. At this point I dont feel inclined to do much more on it and need to decide if we want to run a small quantity of units for others to try.
