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.  |
I don't post on here much, but this is starting to get annoying.
So are you a Nissan engineer? Have you signed a non disclosure agreement with Nissan? Stillen engineers collaborated with NISSAN engineers what don't you understand about that? If they have information you don't have to make a decision on the design of a product then why are you questioning the design? I mean did you have ANY hand in the development of the kit? If so then you may have a leg to stand on, but if you don't have any proprietary information from NISSAN then why are you giving them a hard time? Are you an engineer for some other company and you're looking for proprietary information through backdoor means? Something doesn't seem right here...
