I ran a baseline dyno a little over a year ago with the Z. Weather conditions were much more favorable then. I now have a Stillen CBE and K&N drop ins. Exhaust has been installed for a while now, but I just got around to dynoing the Z after mods. Dynos were run at the same Dyno facility both times (dynojet 248). Overall I'm pretty happy with the gains
Here's the graph with the best baseline from a year ago against the best run with mods over the past weekend (SAE correction). With mods, best run put put down 301 whp and 251.44 wtq. Pretty happy with the gain over stock. Blue line is modded, red line is baseline.
Here are the graphs uncorrected. With no correction factor it shows that I put slightly more power down stock a year ago. I'm guessing this is due to the large variance in temperature( 73 deg vs. 89 deg) baro. pressure( 30.30 in hg vs. 29.84 in hg) and humidity (19% vs. 53%). Blue line is modded, red line is baseline.
Here's an overlay of all three runs over the weekend against the best baseline from a year ago. (SAE correction)
This graph displays the conditions differences between the baseline run from a year ago and the best run over the weekend. The weather conditions were much better when I dyno'd stock a year ago vs. this past weekend.
