just wanted to get so thoughts on air filters, I have a gtr and I am thinking about changing to a k&n pannel or pod filters, but want to know if there is any point to change to pods instead of just a k&n panel? :blink:

in victoria pod filters are legal.

pods make a cool sucking sound(if u like that kinda stuff) but most of them have very coarse elements and let to much dust in if u ask me.

do u want to wear ur engine for the sake of 2hp?

go the k&n panel filter.

The Mines machine runs airbox.

Surely no one can argue with that.

I love that! So true!

I'm about to upgrade alot of components in the engine and i think i may be switching back to stock air box!

Have a look at the ARC Super Induction Box. Draws air like a pod but should avoid being defected due to its design. I run one in my GTR. It actually has two intake panels - on top and on the side. All alloy construction with replaceable filters. Worth a look :)

The ARC box does look cool and efficient however its also around $500 which is abit rich if you ask me.

I'm still not sure if I should convert back to the std airbox or get a custom made enclosure.

Does anyone happen to have a pic of a std R32 GTR airbox?

I went from pods (heat sheilded), back to the factory airbox with K&N panel. The air pick up at the front bar means 'rammed' air at speed keeps the box closer to a positive air pressure which reduces the resistance to flow.

The factory airbox's chamber volume could be improved however for higher horsepower.

The ARC airbox ; where does the air get draw in from as it looks to me like it might still suck in hot engine bay air?

I have decided to keep the standard air box and put a k&n filter in.

I had the box out the other day and discovered there is two inlets, one on top and one on the side.

The one on the side is blocked of from the factory but the bung can be removed easy( this one draws cold air from inside the fender) this also helps with the induction noise and you can hear the standard blow off valves.

I bought both a standard box with a nismo filter (thanks tosh) and an arc box, settled for arc box, so after having each of the 3 options i chose arc box

Benm : at the next cruise you can inspect one if you want, its currently in my mates silver r32

Air filter is a seriously small horsepower improvement. The fact that you gain anything on a dyno is soemtimes negated when you dyno/test with the bonnet 'down' as you always ought to. The airflow characteristics at speed are often quite different to the dyno booth.

If you have an NA car do you get induction noise if you have a podfilter? I was thinking about putting one in with a heat shield but dont want any annoying noise.

You do as i have a pod on my N/A but it runs through the intercooler holes in the car out to the front just behind the front bumper. Dont know if that makes a differences.

    • So, it went to Unigroup for a run in and tune on Friday, everything went (generally) well. In terms of fixes, the engine was good and there were no leaks. It needed plugs (I hadn't checked them because the coil pack cover was on a new engine and I couldn't imagine they weren't new.....but turns out the temporary plugs to just keep it sealed up were in there.....new plugs gapped to 0.8 and it was fine from there. Also, there was a little preload on the clutch slave which caused some slip. I haven't had the box off so I don't know what the clutch looks like; my guess it is brand new and the pedal had not been adjusted....backed that off a bit and it held fine. Last thing will have Dose crying....the idle especially when cold is a bit difficult between the cams, forward plenum, atmo blow off valve and an 80s air management system. It is fine when hot but a little uneven when cold, will see if I can sort or at least improve that one cold morning. Other than that, tuning went fine. It made 245 but was pulled back to 227 which 2 opportunities to improve in future. 1. The factory CAS is not great and was jumping around at high RPM, so Mark took 2 degrees out up top (that is why it stops making power and lost 20kw). Very safe this way and the extra power is available but will require a more modern ECU and better cam (or even better crank) sensor 2. The 2871 in factory housings is very big for a low mount, and the internal wastegate is too small, so it was creeping from mid range all the way to redline....the duty cycle on the boost controller is turned down a little for safety. That is much harder to fix, it would need a large external gate and that would require a whole bunch of other changes, so it will go as it is for now. It feels nice and healthy and safe, so should be good for about a billion laps like this.
    • what sort of caliper are they? If they are a slider and you gave everything a good clean, you might need to regrease the pins. My guess though is they will come good after some abuse as suggested above
    • I don't know what you should expect with an LS, but the oil pressure sounds terrible, sorry. As for the brakes, you can get fade from the pads not just the fluid, although generally that feels like a wooden block not doing anything while fluid feels like an oh shit there is no pedal so you can generally tell. What pads are you running front and rear?
    • Went over my datalogs on a whim and noticed a worrying combination of events. High RPM High Temperature Low Oil Pressure Knock Retard I bought some 10w-60 because I actually think this will be better going forward given track temp is 125C and 10-40 will actually be thinner in those environments. I know I had a leak but it's not entirely sure how much pressure loss can be attributed to that. The knock retard does correlate with all of the above. When it's not present oil pressure is higher. And by 'low' I mean at 6800 RPM the oil pressure was recorded as low as ~35psi pretty constantly. Which is obviously very not good. I'm hoping that thicker oil that ISNT LEAKING will result in a bit more pressure when I need it. Also in the last session I got a very spongy break pedal. I bled the lines as the car is on jack stand right now with the wheels off and I noticed... no air in the lines? Maybe the tiniest bit of tiny frothy bubbles for the first 0.1 seconds of bleeding the whole car? The breaks did come back to me after I backed off (and felt fine driving normally). Doesn't appear to be any leaks anywhere that I can see. Any thoughts on that?
    • Solution, run shitter tyres. Let wheel spin be your weak link 😛
