Help reading dyno sheet

[mcOZ]

Hi guys, just having troubles reading the dyno sheet. Not sure what the numbers in yellow and green represent, does it represent a before and after reading?

Sorry for the noob question! :o

Thanks!

The engines a B16A2, just running I/H/E and previous owner stating that it has been tuned

is that what a b16a2 torque curve looks like.

I dont even know hahah i dont know anything about dynos besides the numbers before the letters kW, km/h and rpm

and also, could you please explain to me why the torque curve looks weird? would be nice learning from someone who knows :)

I'm no expert on b-series but a k-series is has a bigger bump when aggressive cams kicks in and is less wavy through out the rev range. never seen the b16 torque curve before till now

Doesn't look too bad. The smoother the better. Means its been well tuned and you have good power delivery throughout the range, not weak down low then a huge boost around vtec time.

Nice power too :)

It is tuned good, I Love It!

the reason this graph isnt as smooth as others is:

its tuned on a hub dyno with corrections to show kw @ the wheels,
However, the graph is uneven due to no slippages or interference like a roller dyno has, which will show a much smoother graph...

So your saying that in a perfect world where there was no slipage, an engines torque curve is meant to look like that?
