Before and After Dyno - ZR-1 Net Registry Forums

Dyno results from beginning of tuning to last session.

~+20rwhp/+10rwtq

Changes include:

SW Xpipe
DynoMax Ultraflow w Z06 flappers
Re-ported IH's

I think if I went back again I would lean out fuel just a bit morew some more timing at lower rpms. However, one thing that is disappointing is that it seems from the graph that the dyno operator was lifting at about 6800rpm rather than going thru 7K. Looking at the slope of the curve (blue), it looks like the trajectory may have gone a bit higher. Note how the before ad after lines are increasingly diverging.
