Highest hp 370z NA??

Jordo!

Without insanely optimistic values, if we're talking dynojet and SAE correction (STD tends to inflate on NA cars and there's many fudge factors on load bearing dynos), I'd say around 315-325.

That's with EVERYTHING. Full exhaust, lightened pulleys, tune, intake, reasonably nice weather, etc.

Z's with the more basic bolt-on's + tune will be in the 300-310 ballpark on a dynojet, SAE corrected.

Anything much over 330 would raise my eyebrow (and even THAT is really high).

Although... Nismos may dyno a bit higher. Still trying to confirm whether that's an artifact of there being few dynos and all in 5th gear (tends to read more torquey than 4th) or just different VVEL tuning, as the other changes can be accounted for.

Definitely. Then look at % improvement from baseline rather than raw values to get more easily comparable estimates. Also, run conditions need to be close (e.g., similar air temps, similar humidity) to make meaningful comparisons, even with SAE correction.

They have a dynojet (I think) and yet they do seem to have a reputation for finding rather high values relative to other dynojets... not sure what to make of that.
