its kinda not actually
... its 400hp to the crank not the wheels....it says it in the description of the site
....
Excerpt from Z1 400hp package description (https://www.z1motorsports.com/z1-pro...-p-7223.html):
"Nissan advertises 332 horsepower (350 for the Nismo) as the output of the VQ37VHR engine found in the 370Z & G37. Auto manufacturers rate horsepower at the flywheel. From our testing, new stock 370Zs produce around 280 rear wheel horsepower on a DynoJet, which is consistent with Nissan's claims assuming 15% drivetrain loss. Given this drivetrain loss, 340 rear wheel horsepower equates to the engine producing 400 horsepower.
In conjunction with a Z1 Cold Air Intake Kit and a quality high flowing exhaust system the Z1 VQ37VHR 400HP Package can produce 340+ rear wheel horsepower on a DynoJet on 93 octane fuel when properly tuned with Uprev Engine Management. We have not included the intake, exhaust, or engine management systems in this package because many people have already purchased these items. We recommend installation and tuning through Z1 Motorsports."
i hope this clears the air for MANY folks here....

I have posted this video several times. This was a dyno session at Uprevs facility in Austin. I have ordered ECS Tuning 70mm throttle bodies and will be doing a few more secret sauce items that I do not want to disclose, other than they are are all readily available "bolt on" parts. I will also be experimenting with a couple different intake configs and will post the results on my build thread.
You can see the list of stuff done to the car in the description of the video and this car does use the Z1 400HP kit with HF cats not test pipes.
We can argue all day about dyno numbers but i think it is fair to say, you can achieve 340RWHP/400+ crank NA on these cars. It is a major function of $$

But it takes more than just the Z1 kit to do it.

this thread can be argued all day long!
but in the end i think all that really matters is there kit makes power..
IMO dyno numbers should only be looked at on how much power you made before and after putting parts on.
we all know every dyno is going to be different and put out different numbers.

Agreed with Chuckie also, Do you mods, use dyno for before and after+ tuning, then hit the track and come back with ET and MPH. That + curb weight will tell you exactly what the car is making. I did this with mine and the 13.5@ 105 + the 3800 Curb weight( AWD sedan) = 302 WHP, oddly enough that was exactly what my dyno said 
. But it was proved at the track.

Does anyone have the Z1 kit yet? I already have Stillen exhaust, Z1 HFCs, and DC Headers. I have their intakes sitting in my garage and plan to order the intake manifold and the tune soon.

No good tuners in the area and they have a tune specific to the mods on my car. The tune probably made the biggest difference out of all the performance mods I have done to the car so far.

Just remote tune with someone like Seb at SpecialtyZ. He can take your mods into account. I'm sure he's seen or tuned for every single mod available for the VQ platform and then some.
