I would like to hear from other Robi dyno users how they setup their dyno for measuring Monster stock motors for TC sedan class.

And how they analyze the data.

Thanks

That is a heck of a loaded question. First thing is to put it back in the box and sell it.

The Robi isnt bad for a flywheel dyno... much better than a fantom... I would say next to a Turbo Dyno its the best available right now :)

So far I really like this dyno. I can use it without a laptop and get all my results on the dyno display and fast!

As for putting it back in the box, no thanks !

While I cant suggest what to look for a TC motor. I can tell you what we look for on the robi dyno for a Monster for Oval racing.

Set the dyno options to calculate the average watts from amp steps 18-26.

Spin the motor up and then on the main page you will see this calculation in the lower left hand portion of the screen - 18-26 watts - Look for anything over 100 watts. That usually weeds out the good motors from the bad.

Some dont like flywheel dyno's but lately after using this thing for about 5 years we are starting to figure out exactly what to look for. Also once you get a solid benchmark motor and rollout for it, their gear calculator is pretty accruate for stockers and 19T motors.

I will try the 18-26 amp average and see what gives. That's a good benchmark test I can use on my lot of new Monster motors.

Thanks

also set all your amp values in the 2nd screen to what you see on the track.like 16,17,18,19 etc..look for the motor that has a good average that is strong in all those numbers.if two motors have identical power numbers go with the one that has the higher rpm.

I will have to figure that out. I run TC indoor on carpet and I was kinda thinking that something between 18 and 28 amps would be a good range.

Just dont get sucked up in the max power and max rpm number..
like erock said use the right average and that dyno will be dead-on.

Yes MAX don't means much in my book.

I was looking at a 25 amp reading on my monster and got this:

RPM Power Efficiency Torque N
19754 103,2 63,7 49,9

I'm going to try the average reading on the motor. I think I can only set the average up with the software and not on the dyno itself. Need to learn it.

Are you using a laptop or just the robi box itself?

I have the robi hooked up to my desktop and using the windows software. I am able to change the average amps in the software no problem. I just wanted to see how to do it directly on the Robi because I do not have a laptop for the trackside.

The average on the robi seems to default on 20 to 80 amps.
