but its right in line for an LS2. Mine was 340 stock and 385 after intake, headers, exhaust and MTI tune.

actualy when SG closed I did a Dyno vs Dyno (same day within 2 hours) (his dynapack Vs a dynojet) it ended at 324whp dynapack and 321whp dynojet

so that 324 whp was from the same dynapck that when I got the baseline.. you read the thread wrong and didnt do any research before trying to bash on this.

all number I gave here are SAE not STD

330whp STD was on the dynojet as per one of my first thread in this post.

oh and if you meant that a gain on a dynapack is actualy lower than a gain on the dynojet becase the dynapack are known to read higher

first; you are wrong, a gain is a gain no matter what
second; read my previous post about my dyno test
third; a dynapack can also be set to read lower than usual .. its all depend how it was setup in the first place.

I'm definitly doing this beyond a doubt. The tune has to be done else where cause of sponsor deals and all. But I will net same results. I already know the little secert behind the VVEL. It's really not that much of a secert. among tuners. It's just adustments in several ares. I mentioned it to Z1 today and they went silent on me. He he.

Megan370z · 11-03-2012, 07:11 PM

Cant wait to see your result Spohn !!
and maybe it could be even better ! haha

LOL at the "secret VVEL tuning".

For reference, this is the Z1 370Z dyno graph from the beginning of September (before VVEL tuning was unlocked). NOTE: Our car has a Nismo exhaust, which is believed to be what made the major power difference on Mike's car. Due to Z Nationals, and other trackdays we have not had a chance to put the Z1 car back on the dyno for more testing, and to tune the VVEL.

We have a few modifications we have found through extensive testing, that gain additional power on the VQ37, aside from quality bolt-ons.

Thanks for sharing this piece of information. From eyeballing Mike's and your dyno there isn't much difference in the power delivery in regards to how it slopes and how far it extends. Mike's car seems to have a nice vertical bump of a few wtq everywhere, perhaps due to better scavenging from the exhaust manifold, which later translates into that slight edge in whp. Would it be possible for you to overlay the two graphs? Also, from a scale of 1-10 how far along do you think mike's tune is in regards to VVEL tuning?

The jump in the low end looks like a considerable amount with VVEL tuning.

gabe3d · 11-05-2012, 06:27 AM

^Which part of the lowend are you talking about? When I look at both graphs, the similarities I see can be partitioned into three sections, 1) 3500-5500rpm 2)5500-6000rpm 3)6000-onward. If they overlay the two together we might be able to better distinguish but from my eyeball that's what i noticed.

I take reference from honda's VTEC when it changes in lift configuration. That feeling that everyone refers to "dayum VTEC kicked in yo" but here it's the inverse direction which might have been intended by nissan to give it a better low-mid end response. Not knowing what can be accomplished by osiris in tuning in that department, i can only ask the experts like Z1 to see how they feel the progress might evolve from here on out since they've been exposed to the capabilities.
