hydros.biz Lowrider hydraulics information

Here was the main reason why I bought the car. Once I seen  PIC of the reinforcing, I was sold.

And that coil was so straight, little did I know...

Here's the original set up and the battery rack..

Using both front pumps and 24 volts, I could only get abou 4" max. Which I thought pretty much sucked, since I knew I could get 8" with just one of my older pumps using 24 volts. (4" a battery)


Once I plugged in another pump, which was not really a hopping pump, I got about 22" with 5 batteries. (4.5" a battery)

I then made a hopping pump (http://hydros.biz/forum/uploads/av-1.jpg) with used parts and a new Adex, that's when I got 28" (5.6" a battery)  The goal is 7.5" a battery

I still needed to:

Tie the batteries down as they were flying all over the place, and

I needed to fix the rear to avoid hitting the bumper. At that time the test pump I had in there had an external leaking dump valve.

I also needed to add chains or shocks as I had none.

Plus, I really need to pratice hitting the switch,

So all in all, I think it did pretty good for 5 batteries at 28"

What's Up Tony?


I was wondering how those dumps hold up? Or are you running Adex dumps now?

What are you using your square on with the aircraft check that blew apart?

Those dumps pretty much did OK, no leaking, but I would not trust them for any real hopping. The casting seam is what has me concerned. I think someone told me they crack at the seam.

Yes, I am using the Adex and yes the larger aircraft check did fly apart then.

Man I'd like to run all those aircraft valves I got. I want to run the Big Green Hydro-aire and the #8 Hydro-aire and then for the rear, the #6 Hydro-aire straight through without "T" ing. Just run them like they were originally designed for.

For now the Regal still sits in the shop. The Piston pump needs to be removed to push the piston back to check for damages and then add oil, The new Parker check is already installed, and I still need to install the 3.5 tons. Then let me at it again. My switch timing is getting better. Can't wait! Damn


For those that don't know, the piston inside this BMH (Black Magic Hydraulics) pump can fly into the gear head. There is no stop to keep the piston away from the gears. When the check broke, the air pressure inside the gas chamber forced the piston forward all the way into the gear head. As there was then no longer any fluid to keep the piston away from the gears.

Looks good so far.. I didn't rwalize that the piston in the pump can make contact with the pump head. Does Prohoppers' piston pump do that too?

I bought one of the first piston pumps to come out. BMH may have updated the design by this time. And I think some other retailer does use a type of stop.  

I didn't know about that but it makes sense...I havn't really seen any piston pumps up in the northeast.

Intresting dumps, from the "gates era". cant rememberthe name, but i kno ive seen them in Edmunds thread about the 70s units.
How the cars almost 8 years into the future?

well now it is no longer hoping the highest mentality.
More with less is the way to go, the original batts are all dead. Now I have 4 small 24F series batteries.
This is what I have in mind, if I can get 10" per battery then let someone else do the multiple volts stuff,  I am no longer interested. It's been done, now, on to a new frontier.
