looks good!

do you mind if I ask how much it set you back?

US$175, I chose this one becasue it is designed for 350z/G35/M35, it got a TIG Welded bracketry and Vibration Mounts, also a mount for oxygen sensor on the tube.

Alright thanx 4 dat . Btw Paul besides showing dyno results and throttle sound, did u actually feel any difference once the z tube and pop charger were installed( excluding the spacer).

Cheers

here is what they tested on a 350z, claimed that gain 10kw and 7Nm, but to be honest, I can't feel that 5% gain on the wheel.

No not really. Only difference in mods i could feel was the lightweight under drive pulley

I can assure you that the Fujita kit isnt low enough to suck up water. Unless the puddle is up to your headlights, in which case you're probably stuffed anyway.

I'm personally not a fan of the nissan Z tube + JWT combo, but I confess that I havent actually tried it. My main reason is that it still has the "corrigated" (for lack of a better word) section. I'm no engineer but I would have thought a smoother tract to be better...

In any case, I am doubtful of anyone who says that they can feel a power gain with either one. I lean more towards the airbox = better performance.

All of that aside, the noise is the only reason why you would bother with it. I love the noise therefore you may call me a ricer if you like :)

This looks alot more neater, plus think about it, it has much softer curves allowing for the air to pass through with minimal resistance(compared to the Z-tube). I do think that the JWT combo for some reason has the loudest noise out of them all. In terms of power gains, no breathing mod will give you a noticable increase in power which you can feel.

Hey guys...

I CAN feel the difference between my intakes on the car...from when it was stock to when it was high flow panel + ztube to a proper CAI.

And it's not just i can feel it, you can see it in the video too. I have a video of z tube + high flow panel and a video of a CAI. You will notice the CAI video has much stronger top end but weaker middle. In comparison the ztube + panel filter shows a stronger middle but weaker top.

Incidentally, the CAI video shows a 0-100 of 5.6s, if you check frame by frame.

Z tube + panel filter

CAI

Edit - Not saying your car will show the same results. Different state of tune, engine health, mods etc all come into play.

With the air box you you gain 3HP when up and over 100kmh from the ram air effect.

With an open/air pod you can gain between 10 and 15HP, air speed has little to no effect.

This is what i have read somewhere.

There is a thread in here somewhere with a guy sucking up water with his low mounted air intake.

With air box you gain 3hp ? Please explain...how can you gain hp from the air box if the air box is factory installed.

You can change the velocity stack inside the airbox to increase the ram air effect, but it's impact isn't drastic. From my experience, the airbox gives solid low down and mid torque but chokes the engine a little when revving out to 7k rpm.

I however need to get my car retuned for the CAI instead of airbox...that may explain my loss of power down low and mid.

If you put the car on a dyno and get 165rwkw then put the same car in a wind tunnel (wind speed 100kmh+) on a dyno you'll get more power from the "ram air effect"

and before you ask "who would put a car on a dyno in a wind tunnel?" the answer is the guy who built it Carlos Ghosn

I think thats the guy who owns/runs Nissan

Intriguing bit of info but irrelevant for comparison ?

As running the factory box or a cai setup, the air speed parameter for testing/comparison will always be identical between the two, whether it be a dyno fan or travelling at 100km/h.

Also, if you had the pod enclosed within the largest box you can make fit in your bay, then run some decent feeds to it (large enough that when going at 100km/h, it will push enough air into the box to create positive pressure), then you'll get that "ram air" effect. It's basically cramming air into your engine vs it having to suck it in (think turbo/supercharging). I don't know if you're gonna be able to negate the neg pressure generated inside the box when the you go WOT though.. being a 3.5l, it's gonna be sucking a fair bit of air. Come to think of it, i really doubt the factory box can generate any sort of pressure, maybe just reduce the vacuuming effect. The velocity stack built into it and the internal design of the box will be engineered to increase air velocity and smooth air flow however.

Anyways, it's all moot, we're talking like 2rwkw lol =/

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
