Hey guys

Not sure if its just me

But i added a Cold air box to my car on the weekend and my can now feels like it has less power than it did without it.

has anyone else come accross this before

how can i find out if the air box is not doing the car any good without getting on a dyno.

Cheers

Man thats wierd!!! The cold air box should not make you lose any power. Are giving it a proper Air feed??? What kind of air box r u using?? by the way I think your cars hot!!!

thanks dude

Maybe its just me i dont know but something dosnt feel right. maybe a ecu reset may be a good idea.

as for an air feed i dont really have one there it just the hole where the factory pipe use to be which im yet to Duct.

well theres your problem... if you had the snorkel before, and then took it off and didnt do the CAI properly, you wont be getting cold air... you will see a dip in performance...

do the CAI and it should be a lot better :bunny:

I was ment to say where the factory intercooler pipe use to be.

The hole under the air filter.

The factory snorkel and airbox is long gone

I have a HKS pod filter and a CAI that encloses the pod filter in the corner.

Hmmm weird...

What sort of airbox enclosure do you have man? Make sure its not enclosed too much otherwise you might not be getting as much air as you need to. Try ducting it and see if that helps; all you need is to put some piping from where the side mount used to be into your airbox (im sure plenty others on the forums have done it before).

Unless its a major drop in power it shouldnt be an ECU problem. Try getting some good air to it first.

Cheers buddy :bunny:

just cause you have a box around a pod filter doesn't make it cold air induction...

are you saying you have a new pipe pulling in cold air that goes through the factory intercooler piping hole? or have you not done that yet?

An ecu reset is always a good idea. Im thinking it is to do with air feed. Maybe take the box off and see if your car goes back to normal. If it does then its an issue of not enough air. Did the car run well without a box or was it suffering from heatsoak???

I do not have the Ducting in the factory hole Yet but im going to.

Car ran well with out the box but people kept say you should box that pod in car will go better haha so i did.

maybe heat is getting into the box and not getting out so it is making the box act like a pod heater not a cold air box.

ill check for major gaps and add the ducting and reset the ECU

Then will get back to you all with some pictures.

but mean wile im still keen for other peoples ideas

i cant imagine the heat buildup getting worse for installing a shield around the POD.. even without proper ducting, just having a hole at the bottom of the box to draw air in from behind/below the headlight (as mentioned above), should see an improvement. therefore it sounds like somethings gone wrong in the installation. check all piping, make sure POD was reinstalled correctly. maybe clean out POD if it was removed and put somewhere where it could have gotten dirty/blocked.

CAI's are a waste of time, especially when you have a large front mount. They just confine the amount of air the engine can suck in.

When you're traveling along at speed it's not like the hot air from around the turbo is going to travel backwards towards the air intake...

Agreed. You don't get heatsoak when your driving. Exposed pod with cold air routing FTW. Oh wait, except if your not in QLD it's probably illegal to have an exposed pod.....muahaha. QLD FTW.

na induction noise is still pretty loud

one thing I should add is I also put my Exhaust Silencer back in the same day that could help with playing mind games I guess.

Your silencer robs you of power. It restricts your exhaust. Restricted exhaust = less power.

Yeah take the silencer off thats probs your dilemna. you wont get heatsoak while driving especially with that massive cooler. Heatsoak would occur when your at traffic lights on a hot day and you'll feel loss of power upon take off.

Exactly x 2, with the exhaust silencer you restrict so much air flow and create a lot of back pressure just take it off and you notice the power back up again, it might also help if you finished off the air ducting from your front bar to the stock intercooler hole so there is more airflow into the airbox.

      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).
