Q&A Forum
I have just built my self a water brake engine dyno.
I would very much want the start of the run to be more like superflow`s way.
At the start of the run it holds the set start rpm in a steady state untill "start" button is pressed. then it releases and does the sweep...
This would make the run much more repeatable i think.... now i had to use very long "wait" time to make sure it had stabilised the rpm before it started the run, sometimes the start time had timed out before i got he throttle fully opened and so on....
or is this allready an option?
Best regards Einar
@mach_1
i hope you people didnt understand me that wrong.i just want the start rpm to be locked until hotkey is pressed.
so when you lead in to the run the dyno will hold the engine at steady state start rpm until user lets the sweep start...
yes exactly, i think we all want the same feature, as it is really the best method for rolling the engine into the pull when it comes to engine tuning
Did anything happen with this or did it move back in the line with other requests?
Not a problem , just curious it being just a normal butterfly style valve. Ty
@mach_1 I'll take one , but it is a standard butterfly and not a customized globe style valve
I have another project that I want to to use this system for that will reqiure a record bottom . Record while buttom is depressed and stop recording when released.
Hi Manyponies , do you have a actaul picture of the internals of " milwaukee 1 1/2" butterfly valve" ?
thanks

@mach_1 He used a milwakee 1 1/2" butterfly valve. I am using a stepper planetary gearbox
Ok , what valve did Dave use ? Do you have a part number and manufactures details.
You've aware there are planetary gearbox stepper motors avaliable in different ratios and sizes nice and compact units.
@mach_1 I have a Stuska 800 . I still have the load control but have not hooked up a stepper to it to see if it works. . The stepper motor and the control valve were destroyed. I have the purchased the same stepper and valve that Dave used and hope to be able to make the yourdyno system work as smooth.
I am gearing the valve and stepper differently than Dave did. He used a gear and belt drive to ratio the valve slower than the stepper and add torque. I am using a stepper gear reduction box
Hi and welcome to the forum ManyPonies.
Yes unfortunate circumstances the way Dave passed away. Looks like Dave had no backup plan for existing depac systems out in the fields.
What brand/model dyno are you retro_fitting YourDyno controller onto ?
This clip maybe familiar too !

I totally understand you MjPower. You want to control the load at a pre_set selected RPM manually.regardles it be light load to WOT.
Just study the way he performs six power runs and how quickly the dyno responds to clamp the engine while the operater holds the engine WOT.
The clip i posted is exactly that but in graphing mode to run a power run from minimum to maximum selected sweep RPM's.
That method works very, very well, I owned the exact setup in the six pulls video and it worked flawless...... We had a shop fire and the Depac was damaged.......Depac Dave had since passed away and there is no one to repair the systems. I bought this system to replace the Depac. We are still installing the system in the dyno room. look forward to getting this system up and running, I think it has alot of promise!!!
