220rwkw is way too optimistic... if you had a bigger turbz i'd believe it.

But as long as the car feels better, dont worry about high reading dynos. Driveabllity is more important

well yeah, i love the way the car feels now regardless of how many kw it reads. for the first time yesterday i almost lost control overtaking someone

feels great, im happy

wont let me upload the graph at the moment

will try again later

i think what insant is trying to say is the they've bodged up the dyno figure to make it look like a good dyno tune, also the stock clutch is good for about 180-190rwkw, whats it like at 220?

If the dyno used was Bresciani's then my 220rwkw was backed up at Selectmaz very closely.

It may be possible the turbo has been modified without being able to see the difference. looking forward to seeing the dyno plot.

Where the hell were all you buggers all weekend? Phillip Island was awesome.

have you changed the o2 sensor in the last 50,000 ks? goto autobarn, repco get a ford el faclon oxygen sensor, its a standard bosch or whatever brand it is. should take around 1 hour to install at the most. unscrew old one its on the exhaust dump pipe just after the turbo, right behind the turbo heat shield, cut the plug wires off, and replace with new one. The oxygen sensor has two same colour wires and 1 unique colour wire so you can't get it wrong. Match the two same colour wires to the car loom and the unique to unique on the loom. I was getting 250ks to a full tank. Replaced o2 sensor and got around 350 odd

The o2 sensor is only supposed to last 40,000 ks

yeah its around $100 ish. i paid $125 at repco for a AAA brand one i think.

nissan ones genuine are like $250 or something stupid so if you ask for the ford el or as japcab said that place in bayswater

what size is the 31 fuel tank, i think the 33 only takes like 55 litres tops

whereas the aus 31s and vl (im guessing similar fuel tank) took a good 65-70 litres.

does that sound right? the purpose of the o2 is to save fuel by giving feedback to the ecu, without it (as in dead after 50,000 odd or unplugged) the ecu just never goes into save fuel mode, well at least thats what ive learnt and read up on.

    • Bit of an update to this one. Having some issues on the dyno that held us back (boost spiking) and I want to pass some info over you guys and see what you think is wrong with my setup. The current readout on this dyno is 462rwkw on a low reading dyno so keep in mind it is a real world 500rwkw setup on a hub dyno. Don't read into the power figure too much as a sign of the issue. The short and curly of it is: 2.8 Litre Racepace build RB25 NEO N/A Head with VCT (internally standard however ) Borgwarner EFR 8474  Turbosmart 50mm Straight Gate + Mac valve 6Boost Manifold 4" dump to full 4" exhaust (nil restrictions) Wastegate plumbed back in and all angles in the exhaust system are acceptable and not too sharp. GFB SV52 BOV in cooler piping  Turbosmart BOV in EFR Housing   The issue we are having is it comes onto full boost for example at 4000rpm and spikes to 24/25psi, before dropping down to 17psi before slowly rising back up to the target boost of 23psi. It was extremely uncontrollable and the tuner actually had to ramp in boost progrssively with each 1000rpm on each boost setting we selected to try and reduce the amount of spiking. Sometimes we would see a drop of 10psi from the peak at the beginning of the run, to the low, until it took the next 500-1000rpm to stabilise back up to the target boost. The tuner is pretty confident that the straight gate is just a poorly designed product and leaks too much boost upon cracking the gate open and theres no way to fix it other than going to a poppet valve. He's also confient theres no ignition breakdown or floating valves. The fueling is extremely stable as well. Turbo speed is somewhere around the 109,000rpm area. The spanner in the works for me is that prior to this Borgwarner and StraightGate, the car was tuned on -5 twins at a diferent tuner, and he also had issues controlling the boost with it spiking around the same rpm range, so to me this sounds like the same issue and it can't be anything on the turbo side as this was all changed and I think the behaviour is extremely similar, if not the same. We also removed the mac valve and did a run on wastegate pressure and it still spiked and had the same behaviour. My thoughts on possibilities are: Boost Leak VCT Cam Gear isn't reliably activating consistently - (On this however, we did a run with the VCT disabled and the boost still spiked) Turbosmart BOV is not handling the boost? However this seems unlikely to not be able to handle 20psi. I have a couple of logs that I can't make sense of if anybody knows how to read them and can obtain further logs of other parameters if they are not enough, happy to pay for anyones time. The dyno readout with the power figure is the most recent last week. The other picture is from two weeks prior to that where we couldn't break 400kw (we removed the cat), however the issue of the boost control persisted. @Lithium @Piggaz @burn4005 @GTSBoy @discopotato03 I've tagged those that were quite active in recent pages here, no disrespect to those that know turbos well but I missed tagging.

    • I recently purchased a 2018 Infiniti Q60, which has an SD card navigation map. I can see my system has options for real time traffic updates etc, and am wondering if there is something I can purchase to get this working? I can see there are at least updated maps for USA and Canada, but nothing for Australia. Surely Infiniti took changing road systems and city expansions into account when they decided to use an inbuilt navigation over Android Auto/Apple Car Play, or are we doomed to drive on streets that don't exist in the navigation system if you drive to a new area?
    • Luckily I didn't put in etch primer as I just found out it's not compatible with my body filler lol. Also just need to sand the panel anywhere between 150-400 grit so I'm in the clear there. It does say to not apply to soft old paint, I assume that means paint that is flaking, peeling,etc
    • @dbm7 and @GTSBoy thank you both very much! will give that a shot!
