Is that comparable to efr7670  /gt3576 ?

Impeller sizing on the PTE 5862 is very similar to the EFR 7670.

GTX 3576 runs a smaller turbine.

You'd think "broadly" comparable units, but they will all perform a little differently whether in-gear response, max flow, or boost recovery on gear changes.  Housing options in all cases would make a huge difference on those performance measures.

I'll be watching for results/impressions on the 5862.  V band turbine inlet, very nice :)

Precision just released a new turbo model at sema,

7275 gen2, hopefuly start seeing some results shortly

At the 1000+hp mark, going to need something to stop it sucking the seagulls in!!

What application do you reckon Michael? - Strap one to a GTR and go Flying 500 at WTAC 2018, Snowy 1000 etc?

6262 still going strong. Makes very similar power on Mainline and Dynapack

Bloody hell.  Mainline hub I'm assuming?

Either way, huge result - I know this might be a silly question and I don't mean to be a dick by asking it but I'm just interested in knowing your thoughts... are you 100% sure this isn't a 6266?  There are plenty of people making less than this with 6266s and even 6466s :O

Yep, Mainline hub... First time using it, cool bit of kit and very consistent.

Funny you should ask (and I'm not insulted), I just mentioned to my mate who does a lot of work on the car yesterday how I wonder if somehow they managed to chuck a 6262 sticker on a bigger turbo. It's rated at 705hp but has done 766hp on a Dynapack with the correct correction and now 771hp on a Mainline hub. So god knows... In saying that I can't see it really being any bigger because it's making 15psi by under 4000rpm on the road in 1:1 ratio.

Was that at the dyno day simon or private tune? I recall a softer ramp rate being talked about to help a certain au for the dyno day so just curious.. excellent result for the 62mm either way

Just did it yesterday, funnily enough a Falcon with 1100hp had just come off with a ramp rate that made my car sound like it was in 1st gear. We extended the ramp rate to a much more appropriate level

Glad you got where I was coming from - was definitely not trying to be a hater or anything, just thinking through everything and I was fairly sure there was a decent chance the same thought process may have gone through your head too. 

I was pretty sure you'd mentioned the spool was pretty decent and that definitely seems good considering the kind of spool vs power that people used to put up with.  This is a .84a/r hotside eh?  What diff ratio do you have?

Here is a 4.3x drive ratio in 4th gear doing a similar pull with a 1.00a/r 6466 with purely wastegate spring boost control at 1bar (so 1bar happens later than it might with electronic boost targetting an appropriate boost level) and considering how much bigger it should be than a .84 6262 it doesn't necessarily look THAT much laggier.  

Could look at it that it's time for a 6466? ;)  You can see in the preview shot that it's already touching 10psi by 4000rpm and swinging up hard before the gate cracks

0.84 and 4.11

Looking at logs I get 10psi in 1st at 4200 and 2nd at 3800

I've got a 15psi spring in my gate so I can potentially turn off my Mac valve and do a very similar run to that but on first looks it's a fair bit laggier. Assume it's a 2.6L?

That'd be interesting for academia's sake but I believe you - there definitely should be a fair difference between the 1.00 6466 and the .84 6262 :)  

It's a hard result to argue with, nice work!

Will grab some logs tonight. Because of the PPG 6 speed mine will sit almost dead inbetween between 4th and 5th compared to 4th in 4.3 so I'll do both and post average.

Should be interesting on weekend at Racewars, have 1000m run and I'm guessing I'll pick up a lot of speed from the sequential box. Best guess is around the 295km/hr region

That dyno run puts a smile on your face, i watched it several times lol, what boost was that at?

Its funny how precision rate the power of the turbos, when i spoke with them they said compressor maps cost too much to produce so they use real world figures.

I went through the process with them and they spec the 5862 for my car which they rate at 700hp. Obviously uses the same size turbine as the 6262 but has a smaller 58-76mm compressor instead of 62-82mm.

Had been hoping to have mine together by now but its still a little way off, hopefully soon though

300rpm better in the shorter 4th and more like 500-600rpm better in the longer 5th. From experience that would make a big difference to driveability.

Video of the run, about 8 sec by the looks

Sounds yummy :) Great result!

Where are you getting it tuned these days? Need to find somewhere decent to go once I finish building my house and get my car back from storage.

That was the turbo i picked until precision steered me to the 5862.

There was a 4 door r34 in the for sale section with the 6062 recently 407kw e85 25psi

Found it ? it even came off the same dyno as mine

    • Thanks for all the replies fellas. Gonna finish putting it back together and see how it handles the set up. If it starts pinging it’ll be parked.
    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
