Subject: home bru hydro: new jets make 13 volts!!

Yup!

Today I spent some time trying different nozzles just to see if I could
wrangle out those last few RPMs needed to get past 12 volts ..

I bored two out to 3/8ths and dremmeled the crap out of them, finishing
the interior with some fine gauge steel wool wrapped around a dremel
shaft and polished it till the battery died on the tool. I made sure it
was a smooth angle to the tip and got rid of all the scratch marks from
the drill bit.

Put them in and just ran the hydro with a multi-meter and was getting
around 7 volts with a single jet. Pretty sweet .. the most I ever got
before was around 5.5. With both jets on and with some fiddling with the
angles I hit 13!!

So I turned connected them to the batteries and whadya know.. its
charging. The battery bank is at 12.4 and when I hit the switch to
complete the circuit the alternator comes under load and keeps on
spinning!!!

So thats that then. Now just have to keep tweaking things to gain more
performance. I might bore some out a bit bigger and see how that goes.
The nozzles i'm using don't have much room left .. any larger bores and
i'm risking going through a side wall, but they're only like 2 bucks each
so its not a huge deal if I screw one up.

speaking of which think i'll have to get to town and buy a few more to
play with.

Hey

I can't thank all of you enough for the advice and telling me i'm doing
something bone headed once in a while -- its been a huge help.
