Well so far so good...

Install went off without a hitch.

Here's some pics of the pump.

I swapped out the stock 35" alternator belt and now have a 28.5" belt which does the trick just fine.

I already have a newer alternator from an 81 ZX.

So far so good as far as that's concerned.

Morning was cold and grey for once here in L.A. so I can't report back yet on any kind of temperature savings...

notice any difference in power, now that you aren't driving the pump anymore? I would think in combination with an electric fan it should free up a few ponies.

I can't comment on the cooling side of things because all of a sudden it's been like 15-20degrees cooler than in the previous weeks... Barely hitting the 80s right now so I am not having any cooling issues whatsoever...

Like you pointed out though, now that my crank only spins the alternator and nothing else the engine certainly feels a bit more peppy... hahaha... very enjoyable so far.

As a safeguard I've put that fuel pump and water pump on the same switched-to power circuit figuring that if one blows a fuse that will stop the car before any damage can be done.... What do you all think?

Hey Eric, could you shoot a pic of the installed pump? Just curious. Is your cooling fan a pusher or puller?

I think your shut off method sounds okay to me.

Thanks,

Chris

I've got a 14" diameter PermaCool puller fan mounted slightly off center of the radiator such that the fan motor doesn't interfere with where the stock water pump used to be.

If, when getting ready to leave for Monterey Historics, I can take and post a pic tomorrow morning I will do so. Otherwise I'll get someone to take a pic over the weekend and post it on Sunday evening.

Thanks Eric, much appreciated.
