Don't know what EP is but pretty much any motor that drives a electric car will do or even a electric screwdriver motor . If you where to take a elec. motor and hook it up to a volt meter then spin it with a drill the motor will produce voltage just like a generator . Anyway Ill throw one together tonight and post the pictures so you can see it

HELLION

Ok guys I threw this together in a hour because I wanted to test it before dark! That said you should really take your time and build a nice one . I normally put a airplane prop on the gas engine to cool it down. If you use lets say a 9x6 prop then you can lock your throttle wide open it can't over rev with that kind of a load (great for breaking in new engines) If you choose not to use a prop then make the tests quick and atleast use a fan to cool it down. If something goes wrong and its over reving then just block the exhaust and shut it off DO NOT RUN YOUR ENGINE WITH OUT SOME KIND OF LOAD!!!! In one pic the engine is not running but it is turnning over with the starter motor and you can see the voltage this is a good test to see if its working

how do you rate the hp ?

Hellion,

Please look at the diagram I've uploaded. So all you do is connect the nitro motor to the slave motor via belt?

HELLION

To answer your question Marcos: This is a very crude dyno It wont tell you horse power its just a way of testing your engine with a load on it. The more voltage it produces the more power it has. As far as horse power rating I truely don't believe any .12 engine can produce 1 full horse power! They just dont have the torque to pull that much power I have done a lot of testing on this and have come up with this conclusion !!! I also have seen the high buck dynos and if the test was accurate they had the same results as I and engine companies started saying there engines where producing more then one HP are getting away with it do to the fact that there is not a way of proving them wrong even thowe they can't prove they do produce that much power! I hope that someone reads this and can prove me wrong but I dought it

HELLION

Yes revs that looks like the same thing only it tests electric motors

But if you hooked up a nitro engine to the slave motor then we got a Nitro Dyno right?

HELLION

You got it Rev

Here's the web site I got the picture from. engine dyno

after viewing all the pictures from HELLION and the link provided by REV... i think i got a better picture and idea on how to make a DYNO for myself.... and i dont know how HELLION can do a DYNO within an hour!!!! whoaaaa!!!

thanks guys!

and now i know the DYNO that we are making is not displaying any HP reading. Its just displaying voltage on the volt meter and before we do the MODs on our engine we need to do some PRE-MOD reading on the DYNO so that we know how much POWER GAIN we acquire.

am i right?

thanks HELLION

i look back in HELLION PICTURE and also i donwloaded a DYNO SHEET in the web link provided by REV... in the DYNO SHEET also it mentioned about LOAD.


what is the LOAD mentioned?


in HELLION's picture what is that LOAD actually?





thanks!

here is a pic from hellion.

in this pic hellion marked the VOLT METER as LOAD.... but why the volt meter as load? is the volt meter as a POWER READER?
