STILLEN 370Z Supercharger System - Announcement!!!

It's in the works, unfortunately it's easier said then done. The way the piping is setup makes it next to impossible to evenly distribute air to each sensor.

why not put them right before the intake manifold? where pipe turns into two

right! you can't just put 2 MAF's on the single pipe. it's gotta be separate.

Air, like most things, doesn't like to go around bends. Air flow will be higher at the "outside" of the bend. With the split of the pipes before the throttle bodies, I suspect more air will flow through the pipe closest to the firewall as the airflow doesn't have to "turn" as much.

This is an exaggerated illustration, with an abrupt 90 deg bend but it shows the general idea.

Yes I understand this. Air is like anything else it is going to take the path of least resistance. But if you look at the design of the two tubes. there is no sharp bends and it might divide easily believe it or not.the resistance on the two tubes looks about the same other then the one tube is a little longer and i can see that might cause issues but the shorter tube bend comes first so it might equal out. My point being is that it is worth a try if people aren't satisfied with the draw through. Also it is not that hard to do. I already thought about how to do it with weiboy. Now the only thing that doesn't make sense to me is that stillen did this design because the NISSAN engineers said this is how it should be done. Not like they did this because it was a short cut. Also to my understanding this is how the GTR system works also, so why isn't that car having maf sensor location problems? These are general questions I was just thinking about.

Josh or Kyle I know what you guys think about the draw through maf sensors but do you think it is possible to make a proto-type tube that mounts the two maf sensors after the blower and see how the kit performs. I am almost positive weiboy will have no problem being your tester. Hell I will help pay for it if it will settle people down.

Does anybody know if the two throttle bodies have different/isolated paths though the water/air intercooler? Or, is it just one big core and the air is separated to the two cylinder banks after? If it is not divided inside the intercooler, having uneven flow through the throttle bodies is not as big a concern until you relocate the MAF sensor at those locations. While Nissan engineers may have wanted the pipes to be the way they are, I doubt they had MAF relocation in that plan.

MAF sensors have really strange readings when there is a bend just before the sensor.

370Z / G37 Supercharger System Progress: Intake Manifold & Intercooler : STILLEN

That should shed some light. By the way, the only difference with the setup then what the picture depicts is that actual supercharger location (driver's side, not passenger) and the fact the intake has a Y-pipe for two air filters and that's where the MAF sensors plug in.

did you purchase the kit? i was really thinking about parting mines out seriously and of course you're the first i've got in my mind to sell.
