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

      Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you?

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.

      Infiniti Q60 Navigation Update

      By Chocolate Cheesecake. · Posted

      Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.
