I will let you guys posted once I send my upper manifold to Z1 and get the headers from them in July. Last summer I made 323whp/ 247.5wtq with my 2011 MT/IPL from Dynapak dyno. I used Stillen Gen3 CAIT, Fast Intention resonated test pipe, Stillen standard light weight pulley and used my OEM 2.5" true dual IPL exhaust system and Uprev tune. My dyno sheet is posted on my garage pics here.

 

Any updates on this? I was looking at their kit and I'm thinking about getting it.

 

Z1 have their own CAI so it'll make more sense that their intake be in this package instead of owner's choice...

 

Yea as long as you dont have a X sedan this kit will work. The headers wont fit. I have everything on their list except the headers. Had to use Stillens.

 

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."

Interesting...Its a nice little package.

 

You'll never see 340 with their 400HP kit, unless the change the dunk readings to make you happy.

 

How do you know? Have you ran such a set up?

 

read this thread there are very few over 340 with similar setups..

N/A HP BRAG thread - Nissan 370Z Forum

im running everything but test pipes.. if i was still running stock gears i would say i would be right around 330ish whp..

just because they offer a something that says 400hp package doesn't mean you will see it..every car is different and every dyno is different

 

I'm offering 500hp package for only $100, it includes a printout with your name and you car showing 425whp on a dyno sheet. And just $200 for the next step up, 1000hp printout. Also have a slightly used bridge for sale.


In all seriousness, you will never see 400hp out of their BS 400hp package, it's very misleading.

 

its kinda not actually... its 400hp to the crank not the wheels....it says it in the description of the site....

i hope this clears the air for MANY folks here....

 

^No kidding, thanks for that observation, captain obvious. Still misleading and you will certainly not be seeing 400crank out of this little package because as they themselves state, IN ADDITION to the package, you need to buy intake (for your info most intakes actually lower your whp) and exhaust, then buy a tune and pay someone to custom tune it and then maybe if you are on a very favorable dyno and all the stars align and the weather is perfect then maybe you will almost see 400 to the crank but only with the hood open so that you don't have heat soak and lose hp to that pos intake. I call that complete bull****, you can call it whatever you wish. From my own personal experience of having all of those mods and more, no way you would see 60whp gain out of it.

Yes without the TP's running HFC's but we all now the WHP difference in TP's to HFC's in only lilke 4-5WHP at the best. An I'm making 314 WHP. If there is any WHP difference in their shorties and stillen's that's maybe a 4-5 WHP if anything, so just for argument sake add 10 WHP to me and 324 WHP with that exact set up. Oh an I have a ported lower, not even part of their kit.

Like Chuckie state he has is minus TP's and hes's not there either.

 

One of the best quotes I've seen in a while"you are on a very favorable dyno and all the stars align"

Then go buy a lottery ticket! You'll win!

 

They're probably referring to a manual trans G or 370z. The 7 speed auto soaks up some power for sure.

 

not as much as you think. I'm with in 5 WHP of my buddies 370Z,( manual) car, same mods!
