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. Last edited by stormcrow; 03-16-2010 at 10:37 PM. |

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.

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. |

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.

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. |

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! |

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