Full plain text message | Fixed font - Proportional font Subject: homebru hydro update Author: z Date: 11 Feb 2008 Got the thing running this weekend http://www.jeffersonfreestate.org/hh/ Its making much MUCH higher RPM and between 11.5 - 12.5 volts. Still fine tuning the jet angles, but that part is working great. Man just a little change in angle can make a big difference in power. Still have shaft coupler issues. Need to drill and tap the new coupler so I can bolt them together. The coupler wasn't designed to run virtical so I kinda suspected it'd be a problem. Its the only one I could find that would transition from the GM alternator to 1/2 inch without having a special coupler built. Getting rid of the right angles and increasing the pipe diameter feeding the jets made a huge difference. That and I bored out the jets to 1/8th inch and polished them on the inside. I think its as good as I can get for now. As for the shaft I have a plan to weld up a small support around it and add a bearing if the cupler drill and tap doesn't fix the problem. thats all! -z
