Has anybody had any experience using water brake dynos? If so have you been going directly off the motor or axel? Also what brand?

Years ago I had some experience with an old Go-Power Dyno, that was a "water brake" system. Worked pretty well, until I overloaded it with Hp. The water turned to steam, and the unit cavitated. Engine went ballastic, and the thing flew apart.

There are some good Dynos out there, Land & Sea, Stuska, and probably a couple of others. I am currently using an Inertia Dyno I fabricated based on Tom Karuse's information on his website at TDK Motorsports. The thing works very well, using the Data Mite Dyno software from Performance Trends. Kevin Gertgen was, and still is, very helpful, and has an excellent software package that will work with inertia, water brake, or oil systems such as a hydraulic pump.

While an inertia dyno "works" the engine the same way you race it, there are some advantages to being able to bring the engine to peak torque, and tune the carb for max torque. A water brake, or hydraulic pump system will provide this function, in addition to giving torque and Hp curves.

Whatever type you are thinking about, remember that the information you will get is NOT absolute, and won't compare with other dynos out there. You will still have to do repetative testing on your system to determine if the things you do are a benefit or not.

Good luck with whatever you're doing, and maybe we'll catch you at the races some day.

The hot set up today comes from Land and Sea.

They are by far the best in the business. Complete automation of the controls so the run is completely repeatable.

All of the correction factors for barometric pressure, temperature all built within the program, air flow analysis. The list of features is to great to mention and they even have a chassis dyno.

Right now we do have a 8 inch water brake from land and sea but we want to hook it up right to the flywheel, so that we can do steady state testing. Dose anybody make a device that will conect the flywheel to the dyno (land and sea 8 inch,used for dynoing sleds)??

Hi Brandon,
I ahve a 9" Land & Sea water brake with all the bells and whistles. I have about 2000 runs on it. It has been super useful and repeatable (and reliable). It will sweep like an inertial dyno as well as step, stall or whatever you need. All computer controlled.
The guy to talk to at Land & Sea is Dick Locke.........
Also, if I can be of help don't hesitate to email.
I have some info and pictures of my dyno setup at my website if your interested.
the address is: atlantic.net/~inet6126
check it out.
Good luck,
John Gore
