I took my car (2007 HR) to the dyno back in October with our local club, just after throwing on my Stillen Gen 3 CAI. I was very happy with the results. I meant to post this before, but just getting around to it now.

'07 350Z Base (vq35hr)
Bolt-Ons:
Stillen Gen 3 CAI
Stillen HFC
Stillen True Dual CAI
NO TUNE (yet)

A/F ratio was a consistent 12.1 throughout the pull (slightly lean IMO). I pulled out a 279.8 rwhp (let's call it 280). 4th gear pull shown in the video. I'm happy. This was in Ogden, UT, and I'll be taking my car back home to Cali soon, where I will dyno at sea level. Any guesses on the dyno results I'll be getting there?

Depends on the dyno and the temp. Those numbers don't seem too bad for reg altitude, but they could be way inflated due to dyno calibration or correction factor. Do you have details on those?

Agreed, def a correction in an attempt to make it comparable to sea level. Also, 12:1 is not lean.....in fact its rich for an NA car.

Either way, those are good numbers for NA bolt ons. Impressive.
10:1 is normal am I correct?

Yea... i definitely want to see my numbers at sea level. Dyno was a dynojet. What i should really do, obviously, is dyno completely stock and then dyno again with these mods, on the same dyno, same day, etc., as a relative HP gain would tell me much more than an absolute single reading. I doubt I'll go to that extent though.

No, 12:8:1-13:1 is more normal for a tuned NA car.

I got my tune done and @ 13.1...any benefit in going a little lower closer to 12.8 as you stated??

Not really....it's a just a little fatter (richer) fuel curve. No real difference.

i hope to correct my A/F with a good tune soon. I have headers ready to install, but I probably won't install them.
