STILLEN 370Z Supercharger System - Announcement!!!

That really cost Stillen a lot in the Titan community. It shows how much of an impact the internet and forums can have on a company with respect to a specific community. I'm glad Stillen found a remedy to the problem.

Cool, thanks.

any dyno vids yet? I looked through the thread briefly but figured they would be on the first page if they were going to be anywhere at all.

Kyle -

Firstly, let me say kudos and congratulations. It seems you guys have done your best to put out a solid kit and I look forward to hearing some feedback from the soon-to-be new owners.

I do have a few questions, if you will indulge me. You stated that Nissan recommends "draw through" setups for their MAF. Granted, I will not argue the point that both F/I cars that you mentioned and all N/A Nissan cars do come with a "draw through" setup. But, the two F/I cars you mentioned are OEM turbo cars and their ECU programming has been stringently coded to accept the fact that the temperatures being read by the MAF sensor are certainly not the temperatures of the charge going into the intake post compressor. This is, arguably, not the appropriate setup for an aftermarket F/I application running on an N/A ECU.

When utilizing an ECU that is designed for N/A applications, how do you figure that it is better to run "draw through" as opposed to "blow through" when blow through gives actual IATs to the ECU to utilize via the MAF temp sensor versus the colder, denser air pre-compressor of the "draw through"? When the ECU believes the intake temps are 70 degrees, but the charge entering the intake is really 180 degrees, this can be a very detrimental thing.

Also, I take it you guys are using a recirculating bypass valve, as well, and no venting to the atmosphere or BOV? I didn't see anything mentioned about this in the release.

Thank you, sir, for your time.

G35s-Q8

One question in mind, when well we see this kit for the 2007+ G35 Sedan, and the G37 Sedan? I assume the kit well fit both cars, and the only difference should be the tune, and if someone bought the tuner version, then it should be no problem if it's installed on a G35 or G37 sedan.

Here's video with some of the clips we had of the two cars, testing, dyno, etc... look for some in-car 370Z video coming soon..

Kyle@STILLEN

When we say that Nissan recommends a draw-through setup we're not just using other vehicle's as examples, we mean that their engineers told us that the O.E. MAF sensor is not designed to be used as a blow through. We have a very good releationship with Nissan North America and we do talk regularly with their engineering team and this is what they recommended to us.

The NISSAN MAF sensor is not designed to read the air blowing over it because the sensor can not read air density. It only reads air volume. If you compress the air through the compressor then blow it through the MAF sensor the MAF is unable to read all of the air going by it so you're not getting an accurate measurement of air. Again, this information came from Nissan.

Yes, in order to achieve CARB legality we can not vent to atmosphere so we must use a recirculating by-pass valve. However, a blow off valve could easily be adapted to the kit if someone wanted that.

Impressive that Stillen has achieved all the plumbing to fit under the factory hood!

We really just need time and a test vehicle. We plan on test fitting this kit to the cars you listed as well as the 07-08 350Z's.

Hm. Another question -- how much stress is this putting on the auto tranny?

I'd imagine the force means that obvious wear will happen faster, but will it be an excessive amount? There seems to be a lack of upgrade-ability so far for it.

Thanks for the video!

Hey if its good enough for an ex LeMans driver, its good enough for me.

Wow, man. Either Nissan fed you some misinformation or your engineers misunderstood what they were told. Nissan uses a 'hot wire' type mass air-flow sensor which most certainly does measure the density of the air. It does so by denser air causing a temperature drop or pressure drop. This, in turn, requires more voltage from the hot wire to equalize the intake temperature with the temperature of the hot wire itself. Nissan is not using a 'vane meter sensor' which would measure only air flow instead of air density and flow.

The reason Nissan uses 'draw through' on the OEM turbo cars is for longevity of the MAF. That and because a MAF in laminar air flow is much easier to tune. Granted, 'blow through' designs will certainly diminish the life of the MAF, but not drastically.

BTW, if anyone decided to adapt a BOV to your kit, the tune would fall on its face and the car would probably not even idle. "Draw through" MAF setups do not allow for anything but recirculation. You are not a tuner, so I will let you have a pass on that one. But, I certainly wouldn't recommend it to your clients.

holy smokes man... looking good... wow... its really cool that steve still is an active part of the design / testing process - I am really impressed with your company

stormcrow

Kyle - One other request. Loving the videos. But, I was wondering, could you post one of the car at idle without music? In the past the Vortech blowers have sounded like "rocks in a blender" and I was curious if the V3 sounds the same?

Thanks!

Red370

Great video, and as the others have said, hell, if Steve gives the stamp of approval, its good enough for me.
