Highest hp 370z NA??

Nobody else got numbers that high with their headers. Z1 makes good stuff, but they seem to have a very "marketing-friendly" dyno.

yea i've noticed lol

also when mike said his 342 dropped to 320 when on a different dyno that wasnt Z1's dyno kinda says a bit towards that. dont get me wrong i love their products and amazing customer service. just a big number is all.

Yep. Never trust the guy who sells the parts to tell you how much power it makes. They've got a vested interest in making that number look as good as possible. I'm sure that the Z1 parts make more power than stock or other options. I seriously doubt that it's as high as they claim.

hey if it is power to them but i just dont see it.

i mean headers and plenum added to mine i would love to break 340.....just 20WHP addition with just those seem tough.

That was not on a different dyno. It was on the same dyno during a dyno day at Znationals.

Z1 does std correction. 66 degrees vs 77 in sae I believe. It will always show higher. Sae is industry standard. Take off 4% is what you need to do. That's why the motor shows 332 stock vs low to mid 270's at the wheel on dyno jets in sae which is the correct numbers and 18% drive train loss.

Mike has and other cars have gotten within the range as well. It is not just the headers in that package that make more power... The modified plenum is crucial.

Z1 used their intake (which is similar to a gen 3) and a tomei single exhaust + test pipes. If you have gen 3 or equivalent with a High flow exhaust the 400hp package works as advertised.

With just the headers and a tune from someone other than z1 you are right... cars haven't been hitting 340+. But they don't have the manifold or a Jon Parham tune LoL.

And as far as the accuracy of z1's dyno ... I doubt there is a dyno out there that has run more 370z's. They have a wide range of results and would not market their kit at 400 crank HP if they weren't ready to stand behind it.

Do you have a dyno in SAE from them? Because you can't stand behind STD. I 100% believe the dyno is accurate. I love dynojets!! But STD is just not the factor to use.

I'll ask Jon. They just hit 338 again with the package. #checkoutthez1motorsportsyoutubechannel
