GT Motorsports: 370Z Supercharger system development

Sam do you think the larger manifold that comes with the Stillen kit will hinder the VVEL's operation and performance in general? Back in the previous gen Z's, those upgrading to FI manifolds needed cams to get that extra air into the engines efficiently I believe

Let me take my GTM hat off for a minute.

I as a Tuner have some serious concerns about what stillen did with their manifold disghn and yes it will hinder the performance and drivability of the car in general.

issue # 1

The mass air flow sensors contains the air temp sensors so by placing the sensors on the hot side of the blower and then cooling the air inside the manifold the ecu is not getting the right info and will cause a lot counter actions from the ecu due to the extreme air inlet temp it seeing, if you ever touch the hot side on a vortck blower you will literally burn you hand . these ecu are very advanced and this disghn will cause a lot of issue .

issue # 2

The factory ecu uses two different inputs form the mass air flow sensors to control the fuel trim on bank one and bank two and literally there is separate maps for each bank when it comes to controlling the fuel, these fuel maps are not the same meaning the engineers at nissan knew that the amount of air entering each bank will be different and therefor every bank uses it own majoring devise (mass air flow sensor on each bank)to control the air fuel ratio.
Now when having both sensors on the same tube reading the same voltage to the ecu...…i think the answer is clear.

Maybe stillen knows more about the VQ37VHR then Nissan them self .

It is clear to me that stillen rearranged the car around their supercharge kit without taking all the factors in.
