Sometimes it sucks posting our failures and struggles, but since I am planning on doing something similar I really appreciate the open sharing of info. Mine will be a basic BBC and I already have a Kinsler stack injection setup with EFI injectors so your info is valuable to me. I also appreciate the info regarding the Holley system as well as the TC and crank and cam sensor. All info is appreciated.Newold1 wrote:In-Tech, my Dominator Holley ECM has very nice individual cylinder fuel trim and that was what I spent way to much time on the dyno trying to even out the cylinders when I finally realized fuel trim would not work as when I trimmed fuel in the cylinders where the throttles were robbing charge from the other in body throttle it would not hold or be controllable at any higher rpm point and I still ended up with such different cylinder trims I knew at that point that something else was going on!
I am just about finished with the Kinsler modified system and I will post some pictures of that in a few days for interested Speedtalk contributors.
I am using a different timing cover than the one you posted that is for the 58X reluctor as the one I used is for a 24X smaller diameter reluctor. I will post a picture of that cover, cam sensor and reluctor as well as a source for them for you.
Bill, thanks for a good description of what I was suffering from "CHARGE ROBBING"! This is something all builders and fabricators should take care to identify this possible issue developing based on the engines firing order and the ITB fabrication with respect to throttle entrance adjacency. It does really affect things and it can be hard sometimes to identify just based on power and torque results. The individual EGT's and A/F meausrements on the dyno wer the only way I was able to start to see and identify "What's wrong with my damn beautiful engine"!!
I am sizing the length of the new system and it will be a 14.5" long intake tract, end bell to valve.
