Stock 2011 370Z Nismo Dyno
 

First I want to apologize if this post is in the wrong section. I searched for a listing of just dynos but did not find anything, plus I am new to Tapatalk and don't have a good feel for it yet.

Anyway, I have a stock 2011 370Z Nismo that I just had dyno'd in preparation for my Stillen SC install. Will dyno again after install.
My car has 17,400k miles when dyno'd, pulled 3 runs. Over 3 runs, room temp was from ~65-68, engine oil was ~225-235. Dyno was set to 3% load.
Run1: 291.4 Hp @7300 rpm, 247.6 ft-lbs @ 4530 rpm
Run2: 289.9 Hp @ 7300 rpm, 244.8 ft-lbs @ 4565 rpm
Run3: 288.2 Hp @ 7325 rpm, 241.4 ft-lbs @ 4630 rpm

Interestingly, all three runs showed a a small but consistent dip in torque around 4800 rpm. However, I believe these aren't too far off from manufacturer specs.

I will try to post a pic of runs...note, the value is 250 on left side y-axis of graph, it got a little cut off.

Let me clarify, the left axis (horsepower) has a number about an inch down from the top of the graph...that number is 250 hp...the very top of graph is 300 hp.

Isn't that about as much as a non-Nismo makes? Where's the +18HP?

I think most non-Nismo's make about 270-280whp depending on dyno/conditions. OPs number seem to be right on for a Nismo.

Good luck with the Supercharger install OP.

Quick check-in...install is soooo much fun! Stillens instructions are almost perfect! A few areas that are too vague for me (I need instruction like...remove the triangle thing located between the two round things on the side of the motor) but my mechanic knew everything so far to a tee! Only bad part was having to hand file a huge chunk of frame metal at the original DS air vent to get the SC and inlet boot to seat properly. Two of us switching on/off filing for an hour...at my age...I didnt feel too good that evening and the next 2 days.
Anyway, waiting to figure out where the SC heat exchanger get mounted in conjunction with the oil cooler. During my down time, perhaps I will translate my install experience from paper to electronic and post.
