Dyno'd my 2010 Z w/Stillen catback and k&n drop ins
 

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.

Nice numbers. A/F is looking goo also. Are you considering HFC/ TP and a tune in the future?

Nice. Sooo the hotter it is the better it runs?? <---NOOB

Next power mods would probably be test pipes and an uprev tune. Not sure when I'll get around to that though.

And no doom monkey. The runs at higher temps were with a Stillen catback and k&n drop-in filters. The lower temp run was a stock/baseline run from a year ago.

Isn't 286hp rather "high" for a stock 370z? I thought most people were seeing 260-270 at the most (non nismo)?

Nice.

Usually you make more power in cooler weather.

It is on the high side, but as we know no dynos are equal, just as some cars will make more power than others due to differences in manufacturing.

The important thing is he is running on the same dyno he did his baseline on, so his run comparisons will be fairly accurate.

For reference, a stock 350z puts down about 229-235 whp on the same dyno. And an e92 m3 put down around 350whp.
