Here are the most resent results from a tuning session we had with the Nismo Z with the Vortech upgraded Stillen supercharger kit. We were loosing boost up on the top end during our last session so we tried to take some steps to make sure we were getting everything we could out of it. We replaced the belt and swapped out to the Turbosmart dualport bpv. Also since the last tuning session we switched to the GTM Resonated test pipes and the Berk Technology dual exhaust. The car sounds absolutely ridiculous now! Our customer Nate was amped up and from checking the forums he said we seem to have helped him create the highest HP supercharged 370z ever posted. The car pulled 484whp and 400wtq on the first pull. The graph looked decent but we continued to clean it up some. After working on it for another hour or so we rolled off the dyno with right around 465whp once the heatsoak took hold, but with a smoother graph and more power in the mid range thanks to the VVEL tuning.

Can you elaborate a little?

So this Stillen SC kit is no longer a Stillen but a vortech correct?

Chuck33079

I thought it was always a Vortech blower.

As you can see the graph wasn't perfectly smooth like some of the others we have posted. It might be tolerable This was our highest peak power run, but it was also one of the first pulls of the day so there was much less heat soak. We continued to adjust the VVEL, fuel, and timing tables after this initial pull. I'm confident the car would make even more power on a cool run at this point. However by the time the tuning session was totally complete the heatsoak was robbing us of roughly 15-20hp peak power, but with the additional VVEL tuning we were making more power everywhere else on the graph.

Yes this kit uses the V3-SCi trim blower. The 928Motorsport impeller does not fit this particular blower. Vortech however has a factory upgrade impeller that is larger than the one included in the out of the box stillen kit. This impeller seems to make good power increase over the 928Motorsport impeller, which we have also tuned, that puts out around 420-430whp.

It is and always will be a Vortech blower, there's just not much left that is Stillen about this particular kit outside of the intake manifold and their bracket


Thanks for the comments and questions guys!

Actually, I was hoping for a little more in depth expanation of the changes to the VVEL specifically. A lot of us boosted guys have been waiting (im)patiently for the results of tweaking the VVEL.

Ill see if my tuner can chime in additionally this afternoon for a more in depth explanation or what was done. We have been meaning to do a little write-up on it. Every Z we have been playing with we have been picking up power in the mid-range, and making the torque curve fatter. Great technology, I'm just not the right person to tell you what exactly was done and how the software works. Also once he is done in the dyno room I will be able to grab the other graph and overlay them to show the changes in the midrange.

And now I have wood.

wow, 400 tq on Stillen kit, that's amazing.
So the only upgrade is the Vortech impeller kit, no other pulley, tubing, MAF upgrades, right?
is it possible to see the pre-VVEL dyno graph on this?

But job well done Motion Lab.


BTW, you've two CBE's listed.

From what I think OP said was its pretty much no longer a Stillen kit. The title will be confusing to some.

FireDan50

Cant wait to get my Z up there for y'all to work on! Definitely thinking about doing that impeller upgrade now. Do you think I should go with the Turbosmart BPV you guys used here?

Motion Lab

We upgraded the original Impeller with the largest one that Vortech offers for the V3-SCi blower. We also swapped out the injectors and fuel pump to make sure we weren't running high IDC when approaching that 500hp mark. Along with the impeller he also already had the smaller pulley. We have not exceeded the MAF sensors yet, however I think during the last session we were getting pretty damned close.

Well we tuned it when it made 460whp and had already began to play with the VVEL. We were able to pick up even more with additional time on the VVEL calibration, but I would really need the original charts from where he made around 420 or 430whp to reflect the true differences in the mid range. Not sure if he still has that or not.

Also thanks for pointing that out I corrected the list. We moved from the NISMO to the Berk. We also swapped out the Motordyne ART Pipes for GTM Resonated test pipes.

Its still a Stillen kit regarding where it sits and the pipe routing. However since installing the original kit we have upgraded the injectors, fuel pump, supercharger impeller, supercharger pulley, and the BPV. Hes been modding the kit since he got it haha.

Dan,

The impeller upgrade made the power jump up pretty good for sure! He is also running the smaller pulley. I think adding the turbosmart into the mix isn't a bad idea. The Stillen valve isn't bad, its just not designed to be pushing as much boost. It would be a good addition to ensure we weren't leaking boost out of the BPV, but not %100 required for what we have discussed doing on yours currently. I think only until we were pushing 10+ psi did it present an issue. 9-10 psi it seemed to behave fine. The turbosmart also makes cool noises .

Also I will have your Quaife diff sooner than we thought. Itll be here Tomorrow! Ill send you some pictures when it arrives.

Original stillen blower with a modified wheel, stillen intake manifold, stillen intercooler pipe. Why would this not be considered a stillen kit? Kind of reminds me of the GTM 1.5 kit.
