From the compressor maps of the real GT3071R it should get there but I wouldn't count on it being responsive in large housing single scroll form . Didn't you used to say that a HKS GT2835 Pro S hit the straps at about 280-300 Kw because its the same compressor wheel just without the cropping on the turbine blades . I do have one idea on ice but no hints just yet - pending ...

GCG was supposed to have had the GT3076R 52T though being a special order item it may not be discounted like that other IW GT3076R 56T you mentioned recently . I imagine its cheaper than HKS and you don't end up with the wrong turbine housing .

How did your friends 0.87 A/R housing go ?

Cheers A .

Not sure.. :) I do know Grepins GT2835ProS had boost drop issues over 270-280rwkw but he did manage to push over 300rwkw with working on improving the motors airflow via plenum, cams, exh. manifold etc etc. ~313rwkw from memory. If he were to hold the wastegate shoot power would shoot up over 300rwkw, possibly hks's wastegate flow is just a little too good once then pressure builds up behind the flap blowing it open.

So if thats the case and they are the same comp wheel which I wasn't aware of then yes it should do it with no real problems. :)

But from what I've seen its definitely not possible on a stock cam'd motor.

Steve with the .87? As I said above it made 320 something rwkw on a shade over 20psi. Its been some years so the details are beginning to fade. :) But it did go well and appears to hit the ceiling of what a few other GT3076 and hks3037ProS tend to make and initially he complained of lag from the .87 which I believe was sorted with cams and a better tuner.

He still floats around on these forums from time to time.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Yes correct. Also, I'd avoid applying it to soft paint (however I doubt you'll ever have to deal with it in practice). So any paint that hasn't fully hardened, could be a 1k paint that never fully hardened or it could be a 2k paint that was laid down thick and hasn't yet fully hardened.

      Borg Warner EFR Series Turbo's V 2.0

      By Borci88 · Posted

      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.

      Infiniti Q60 Navigation Update

      By Chocolate Cheesecake. · Posted

      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
