The Patterson side pipes were symmetrical. Bob only had to design and build only one header model---they would fit on the left, right, front or rear. Did require tailpipes of different lengths, tho---

Some Aeromarine engines had special front gear drive setups that also drove the metering unit. Think of the Lucas metering unit as a fuel distributor. The output at the injector is timed or pulsed as the metering nozzles spin in the housing passing each injection port. The faster the engine spins the more net flow you get. The fuel output is also multiplied by the throttle position with a mechanical linkage from the throttle shaft to the cam linkage on the top of the metering unit. Think of it like a vacuum advance mechanism. These were the hot ticket back in the day and I believe Lucas had a patent on them. Richie Powers adapted them for marine use when he worked for Kiekhaefer. Jeff |
What SB said, Absolutely a cool thread with some very special contributors. Thanks for the history lesson guys. It's very much appreciated.

Jeff Thanks for triggering my memory--Jeff-- The first units Richie built used the Crower manifold----and the right angle drive---and used a Gilmer belt to drive the high pressure pump---and an electric high pressure pump to be used for starting and low speed operation---the belt drive was troublesome---but they did perform!!! Mr. K. was soon making his own manifolds (pictured) and then the gear drive 'accessory' section that could drive the high pressure pump, alternator, water pump,distributor/or/metering unit---all without belts. Mercury Marine soon came out with a similar unit using the Crower manifold--but used the Hilborn constant flow system---just like the one used on my airplane!! |

Looks a little different to me, the engine hatches look like the boxes on a 35 or a 40.......pretty hard to tell though but those motors sure look pretty! Here's Aero III as Realite Charger. [ATTACH=CONFIG]534417[/ATTACH] [ATTACH=CONFIG]534418[/ATTACH] |

Jeff, my understanding was that Crower made the early systems with Lucas. I don't know if Jim Kinsler worked for Crower but he ended up buying the tooling and a load of bits from Crower and it is now all branded as Kinsler. I think the Kiekhaefer units were basically just Crower/Lucas units......with of course the infamous red stacks!!
7xChamp...........Tell us a story!!!! Jeff |
