Help me with my abysmal ignorance

Are you going for the land speed record?

Of course your car will have faster 0-60, 60 ft, and 1/4 mile times with more power.

Best bangs for the buck are:

1. K&N panel filters plus smoother intake tubes (cobb or HPS).

2. ebay test pipes (get ones with extra long defoulers to minimize chance of CEL; can also cram steel wool in bung to filter exhaust gasses further)

3. A better flowing Y-pipe, or pick up a used Nismo cat back exhaust (OEM or or S-tune version).

4. Osirus uprev tune to bring it all together.

That will bring to around or just over 300 whp on a dynojet (typically begining around 273 +/-5 ), and should cost you under or around $1500 - 2000 in total.

Happy modding

Not trying to hi-jack but the ARK website has vids of their CBE on a dyno producing 302 whp alone. There's no baseline run, but most 370's seem to be dyno-ing around 279 stock on dynojets (of course conditions and corrective factors play a role). They're working on getting before and after's, as 23 whp from an exhaust seems like a lot.

That seems high as others are claiming around 18. Although a lot of conditions do factor in like you said.

That's nice.

Do independnet dynos confirm that? Are they using SAE correction (conservative) or STD correction (overcompensates for NA).

Anyway, with no baseline run, you cannot determine anything about the % improvement from their exhaust, so a value of 302 is meaningless.

I'm amassing a database of 370Z and G37 bone stock and modified dynos, so I know what I'm talking about. Moreover, I am making reference to SAE corrected values, not happy overinflated STD ones or randomly high/low uncorrected estimates.

I'm a data driven, "bang-for-the-buck" kind of guy, so those are the recommendations I make to anyone who cares to listen.

Of course, people are free to base their decisions on whatever criteria they want and people can spend their money however they choose.

I'm not selling anything, so it's no biggy to me -- I'm just looking out for other car guys who may not have the wherewithal to consider all these factors before laying down their hard earned cash for stuff that may or may not live up to expectations.

P.S.
273 +/- 5 = as high as 278, 1 whp less than you noted. In other words, that is close to the range I have found, albeit on the higher side. I have also seen multiple baselines closer to 268; they tend to dyno higher after accumulating 2-5K on the motor, most likley due to continued wear-in.
