Thanks for updating this topic, nice complement to the information on the Packard FI you made available earlier.

Glad you enjoyed seeing the car. We plan on bringing it to Galena. Have not had a chance to get it running (always seems there is something else to do). The setup pictured is one of the prototypes, not like the one I have. This one has a welded up intake manifold by the look of it. I do not know if that is a filter under the bracket. Our Executive has factory air.

You are a brave man! From what little I know of these FI systems is from race cars running at Bonneville. As long as full throttle at warm temps are the only criteria, they work great. Trying to tune the cold start, idle, part throttle at varying temps is a challenge no factory engineers ever conquered. Let us ride along with you. Thanks for the photos.

car test data fuel injected vs carb. Looks like they were driving it at all speeds

Roscoe,
Does any of your paper work list the fuel injection as code (RC)"Racing car equipment" or (HR) "High speed car equipment" ?

Thanks for posting these Packard/Bosch FI engineering papers!
A couple of things that jump right out are: 1) Optimum BSFC curves are very difficult to obtain with the manual controls of the day. Obviously, computer control with sensor feedback solved this problem on modern engines. 2) According to the report #374 paper, Packard engineers installed a vertical divider on the siamesed center exhaust ports in order to minimize exhaust mixing between 3&5 and 4&6 exhaust ports. Hopefully, this would have lead to a recasting of the V-8 head in order to achieve true separation without the constriction of simply a vertical divider. Craig
