Hey, i just installed a Pod Filter, Im just concerned, with it sitting just in the engine bay, is it sucking in to much hot air?

sorry if this has been covered but i just dont wanna damage anything...

cheers

Its ok for it to have hot air, its just better to have it sucking in cold air rather than hot. If it really worries you run some pipes that draw in the cold air, or make up a littlecold air box

yeah, like the original pipe that was running from front of car to air filter i have left for now, but i was just concerned as the FMIC is still stock that the temps would go higher....

this is tricky...pod filter is installed in hope to suck in more air into the engine....

however the disadvantage being, as the engine bay heats up, hot air is being sucked instead of cold air....

warm air has lesser density compared to cold air. Which also means that there will be lesser oxygen content in a meter cube of air in comparison to the more dense cold air. And combustion rely on oxygen in the air...

The intention is good, some ppl install air box or heat shield around the pod filter, however that defeats the initial purpose of trying to suck in more air ~~...so if heat shield were installed, in overall you get air warmer than from the standard cold air induction and a more restricted flow than from a non shielded pod filter. Which ends up pretty much in similar condition to a factor air filter.

I read once in magazine saying that it is actually best to leave the air filter standard esp Vtecs due to the resonance mambo jumbo which I dun really get...

I did get the HKS mushroom tho and my 0-100 speed was a few secs slower than it used to be (RSM)....but I didn't regret switching the filter..I like the breathing sound it makes...suking thing...

NA engines are a little different in that respect. They get affected more by resonance in the intake system. The stock airboxes will tend to have some kind of resonator pipe / chamber which stop it from doing that.

The resonator chamber smooths the airflow out during the entire rev range, which means the power delivery is also a lot more even. I've read that by altering that chamber, you can actually get more top-end power at the expense of low-end. But its the kind of hydrodynamic black art that you'd need a big R&D budget to develop, and that's easy to get wrong and hard to get right.

FI motors, because they tend to forcibly suck air through the induction, are less likely to get that so running a pod filter doesn't affect them as much.

As for heat soak, I'd concur with what everyone else has said. As long as your engine is light tune, its safe but not ideal. I'd recommend obtaining some kind of heat shield and maybe a CAI setup, but its not something that is going to force you to not drive the car until fixed.

silver, did you car come with a stock snorkel that connects to the factory airbox?

My one is nismo so I'm not sure if this i sacutally included with all R34s

If you do have this item, simply place it over the pod and secure it so it doesnt move around and that will bring in fair bit of cold air into it.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
