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.

Share theee secretss!!!

cough cough
Haha

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

gabe3d · 11-05-2012, 05:27 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.

Mike · 11-05-2012, 08:44 AM

just for clarification, my exhaust is straight pipes all the way back to two 12" glasspacks.

DR_ · 11-05-2012, 09:47 AM

Do you think 330whp is achievable with your headers and your tune with Berk HFC and Stillen exhaust?

I couldn't tell you that info for sure until I tune one with that exact set-up on our dyno. I'm sure someone can on a dyno other than ours as I see some crazy numbers for the mods.

daisuke149 · 11-05-2012, 10:50 AM

i know people with LTH gen 3 and CBE and tunes in person.. dont need to look at someone far away's profile. you do not just gaine 50-60whp from that.

So again, please provide some actual proof in the form of dyno sheets from multiple people.. as you stated.. typical gains are.. so to be typical it must happen alot.

well you are wrong as I did gained about 68whp without vvel tuning.
dyno sheet are also around.
doesnt matter what we tell you that it can be done you will just not believe.

as the guy previously look at my Journal and you will see what was involve to get this high.

-custom CAI & MAf tube (Stillen ver3 are very similar in term of adding power)
-custom TB
-custom HR intake manifold (which usualy give a lower peak power than the VHR)
-PPE step long tube header
-custom x-pipe & straight flow muffler
-Uprev tuned by me.
-lightweight crank pulley *NST*

there is still power to be had with a stock VQ37vhr engine but I blew the engine before I was almost done with the next project

edit; I removed the A/C delete from the list because that was after my last dyno session.

MJB · 11-05-2012, 11:22 AM

John, just to clarify since I went ahead and ordered the 350z headers from you guys,.. The only thing I need is either 350z test pipes or hfc's, no other modifications?

Nothing else is needed. You're going to love them. Thanks for the order!

SS_Firehawk · 11-05-2012, 12:06 PM

I'm running long tubes with every bolt on to the motor and exhaust. Only thing I don't have is a flywheel/clutch upgrade. I was at 316 with it's best run, but was untuned. I don't think a tune was going to get me 14whp. My baseline was 266-270 FYI. My tuned numbers are 10-12whp off, but I'm thinking it was heat killing the numbers.

Anything over 50 is doing great, over 60whp over baseline is an anomaly, a gracious dyno or a combination of low temps, full bolt ons, tuning, low elevation, and at least a dynojet. The dyno I've been using is reporting around 18-20% drivetrain loss in crappy Vegas weather and elevation.

I don't know where Mike is, but your numbers are severely negatively affected by power and elevation, even with very high CF's.

At sea level in FL, where I am, the summer heat and humidity will absolutely kill power, no matter how much correction is used.

The SAE guys need to develop better corrections for their estimates...
