okay, so i been wondering this....

how come every dyno reads different? calculating horsepower is just a mathmatical formula....so what would cause different brands of dynos, to read higher or lower? how would you know what dyno is exactly right?

 

Some are loaded and some aren't, they are mechanically different.

 

i understand that...but of course there needs to be a load on them, cause theres a load on yuor car when the wheels are touching the road. why would some not load them enough, or load them to much?

i just hear way to many people saying "if i was on this dyno i would of made more power, blah,blah,blah...."

 

im interested in learning about this as well

 

heres an article I came across on why dynojet numbers are the way they are.

I know dynos are just a tuning tool, but I agree with you.. 1 HP is a set unit of measurement just like 1 foot. Every measuring stick measures 1 foot the same, dynos should measure 1 HP the same.

But thats just not the way it is, so compare your numbers as you go along to the same dyno..
