I'm doing some thinking. I'm not a slave to fashion, but I am to
function. There's enough shaft space on the top of my v4's flywheel to mount another pulley, and I'm considering mounting about a 50-75 amp 12volt alternator on an external bracket and running a belt though the cowling. The reason why is because the meager 10 amp stator on the engine itself jsut isn't going to cut it. I can modify the brackets so the external alternator is independant of being under the hood with the gas fumes. I know the 85 will suck gas anyhow, so what's a bit extra drag? And I know the contraption will look like a tumr hanging off the side or rear of the engine, but I can do some specific cowling work to modify it so it isnt' so 'tacky' . Even Rube Goldberg had good ideas... sometimes. But also like what Gfretwell pointed out, once can make a charging system off a small gasoline lawnmower engine contraption. I've done this too. But there are some really neat, small and highly efficient alternators ont he market noow that have less drag of horspower to produce the same amount of wattage as apposed to even the automotive units made 20 years ago. In other words, I can make a simple 30 amp, self regulated unit run off a 40cc chain-saw engine.and the exhaust can be quieted down so you don't hear all the buzzing racket, and this can be an advantage because both engines would share the same fuel mixture. OR, I might ust go by an 1800w gasoline inverter power pack. Even though they may not go very far, the wheels are turning |

I mean, I have the parts and it is in my line of work, and I'm an auto- electric mechanic so..... It just seems I should be able to come up with something I know about instead of paying a wad for somebody's stuff. And I believe I can do it for a 10th of what that Honda would run....if not less. Like I mentioned. I'm not a slave to fashion, and we're going places where fish poop, and not a gala outing at the Yacht Club. Besides, if it goes overboard, there's no real loss, but the Honda? I'd probably have to go diving for that one. |

Why not just get a spider coupler and mount it directly above the crankshaft. Then you could lift it straight up and remove the cowling. Less danger of finger damage too. Put a little top hat cover over it with slots so it will breathe. You would have to build some kind of bracket but you were doing that anyway. Set the alternator down on studs and tighten it down with castle nuts and cotter pins. Greg, I'd considered a love-joy connection, but there's a lot of alignment issues and vibration issues, plus the extra bracing etc, so I had to rule that idea out. but I will confess it would make a neater package. However I didn't totally strike the idea. With some of the newer and more compact units like the 45 amp Nippon Denso internal fan alternators that run very smooth and are at least 40% smaller than the old Delco 10-SI. |
