home made dyno results

heey my brother has made his own dyno, it is made using a micro phone and some software he downloaded although it isnt for automatic scooter ( he is using on vespa pk 135) it still worked ok but gave me a higher reading. fort i would post the results for you to look at.

 

are you trolling?

 

what is trolling supposed to be

 

trolling is like luring somebody in to a faulse pretense to gain a reaction. I say this because there is no possible way of getting an accurate dyno printout by using a microphone

 

i know you can work out speeds of cars using a microphone so maybe its possible?

 

its called GSF dyno its supposed to be quite accurate, here is the website

There's no way in hell that's even slightly accurate, probably about 6-7hp off.

 

You have been trolled my friend

 

i have learned how to use it better and these are the results

 

and no i have not be trolled quite a few people are using this program

 

I don't see how anything can be accurate just using a microphone??
Surely it'll be louder the closer the microphone is, or further away, so different readings???

 

you attach the black to earth and the red to a power source then plug it into the microphone and press record, it is not just a microphone it attaches to your engine and produces a sound graph

 

have also tested this on a my brothers piaggio nrg mc3 50cc with a pm tuning exhaust
