hey muz have you been to the dyno tuner just off anderson street dyno dynamics it's near ray hall?

are you the one that tried to drag my wife off in a silver r33 if so your car definatly needs a tune

Thanks mate, I take it you are referring to Cairns Dyno Tune. He knows even less about PFC's than SVS unfortunately.

No sorry I'm not into street drags and the only Silver R33 I know of and have seen belongs to bloke. Always willing to chat though. Also AKAIK, mine is the only black R34 in town but if there is another one, I would like to meet him and compare notes.

Cheers

Muz

that means there isn't any other dynos in cairns

some one answer the call we need a tuner in cairns there is at least twenty of us that need it done

hi muz

i have same issue as yourself. changed the 02 sensor, and nothing.

anyways, the other week, i just happened to buy a K&N panel filter for my car... i thought hey what the hell.

anyways, from always struggling to hit 250,km im not pushing 350km a tank on bp ultimate! (i dumped optimax - didnt perform like ultimate!)

but yeah thats my sad story of poor fuel consumption... i feel ya mate!

Don't qoute on me that. I've the same situation as yours b4, however after i installed the Earth ground kit and reset the ECU. Now i could get about 380-400kms per tank city driving. i think u should try to reset ur ECU first, to see how is it goes!

Hope this help

steven

I've always had excellent fuel consumption from my GTS-T and boost hasn't appeard to make any difference.

On the dyno I was watching the AFR's under general moderate acceleration and noticed they are always hanging around the mid 13:1, under light throttle it would almost immediately flick to 14.6-14.7:1.

The car did feel a little lazy with the transition on to boost (when boost was ramping up) but once it hit the AFR's would go rich and it would pull nicely.

From what I've seen tuners tend to try and get the AFR's around the 12:1 some times a little richer in the boost transition period.

This boost transition period is where the general driving hang around.

Lean this area out under moderate acceleration and you should pick up fuel economy but loose a little punch.

I wouldn't think the punch under light throttle would matter much as if you want the punch you put your foot down boost comes on and down goes the AFR.

Due to the crappy timing light it was returning just under 400km's a tank.

Timing is now up from 5degree's and back at the std 15degree's.

I've been watching the RB30DET on the stock RB20DET ecu and is now returning no less than 430km's per tank with a heavy foot and city driving.

Occasionally nudging 500km's a tank depending on how hard I accelerate when I first click the gear.

Thats some impressive fuel economy Narlzz. :rofl:

Nudging in to the mid 9L/100km's. :P

    • 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.  
    • 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       
    • 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).
