Depends a lot on the dyno, the drive-on ones are all different.
Good for pub points comparo on the day, but hard to compare to others, or even the same dyno at a later date.
Lots of variables. We found 8HP in a race Mini by swapping the sticky rubber for hard crappy road tyres.
Did it go faster with the new found horses?
Might have, until the 1st corner...
Like I said ^^ good only for pub points. Or engine tuning.
On the other hand, a `water brake' engine dyno has few variables, and is far more sensitive to minor tuning changes. So better for engine development.
