Intake 6 deg advanced. Ex 4 retard. I have tried a few different settings but it always likes 10 deg of overlap the best. Turbo comes on strongest there and makes best overall power band. Did everything from no overlap to 20 deg overlap...10 is best but there are good gains in the 6-10 range if you are worried about idle quality. Also 8 deg intake advance and 2 deg ex retard made similar power. Power drops over 10 deg though.

It will hit 700 whp tonight. I regapped my bcpr8es plugs down to .020" to fight high boost breakup. Yes turbo is really spinning but it's 41 deg F here today so it's still relatively low rpms to move the air.
Boom. Check them digits out. Sucker woke up at 30 psi in the midrange. 26 on top. 20171208_222058.jpg

American dyno is bloody awesome

I guarantee this car has high 130's if not mid 140's in it. It is flat out scary to drive...recall I ran 128mph on pump 93 (your ron98) on 18-19 psi boost in the 1/4 and it pales in comparison to how it is now. It is an absolute ANIMAL...

You'd wanna be pulling mid 140s to back up 740hp ?

Gunna repeat myself here... But the 8374 is a BEAST of a snail! 

Driven 3 8374 cars ranging from 2.8L - 3.2L and it really makes my tip drip! ?

Don't mind me, that was just an observation on the figure differences from Aus VS USA. It wasn't meant to add or detract from your comments.

Anyone here got a source on 90 deg compressor covers for the 7670? I thought this was the B2 frame, though it looks like the outlet of the 8374 is 2.5in, and the 7670 is 2in, can't seem to find an "OEM" style fix for this.

Would appreciate something less agricultural than simply welding a 90 degree on literally in a backyard. Given the outlet is VERY close to the 6boost manifold runners Silcon is only going to last so long. So long in this case meaning it died yesterday and I doubt very much that the heat shielding aluminum stuff I put around it is going to keep it alive.

Yeah, glad you said that - I start rolling my eyes a bit when people make comments that "If it was a real 700+whp then it'd run xxxmph".... fact of the matter is dynos are just tuning tools and it's not that American dynos are happy, it's that MOST Australian dynos read lower than what pretty much everyone else in the world use unless they have imported a Dyno Dynamics dyno.   740whp sounds about right for high 130mph/around 140mph to me from the Dynapacks that I am used to, and sounds about right for what an EFR8374 is capable of.  I'm guessing if this dyno reads like what I am used to then the turbo will be within safe rpm, JUST.

Nice result, I look forward to hearing how it goes - E85 is awesome, tends to make the car feel better in general ... not just when tracing the target boost curve.  Been good seeing this setup gradually be refined and start showing what the EFR8374 is capable of on a nice RB :)

not sure if that worked or not ?

Awesome graph and power/response! ima sure it would drive better than it looks on paper! (i was also comparing ur graph to my T04z dyno sheet, obviously your EFR has improvement everywhere hahahha)

Ima also looking at upgrades now so may I please ask why 6boost single wastegate instead of twin wastegates? Prob cheaper, but wouldn't twin wastegates be more ideal?

Looks like it would be mega fun to drive, I wonder if the million dollar plenum was worth the investment. (besides the fact it looks good).

the plenum is deff not worth the investment the amount of work invloved and extra lines and hoses needed to be made/brought to set it up, it should make 500kw in NA form. The plenum's are a waste, Nismo FTW. 

 

I went 60mm single gate, for packaging as theres not alot of room under there for 2 gates. Also the waste gate pipe is split anyway so you get the same effect with the single gate just less mucking around.

I looked at that option but after my 6Boob experience i chose to go down the path of the HypeEx/Fabtech true twin scroll manifold with twin gates... He performed artwork on it and it all fits pretty well! Going to be a prick to take off over the next few weeks so i can get the engine out for a build.

Will be interesting to overlay the graphs once i get mine running ;)

Yeah so true 2 gates would be alot more packed and costs more (altho $ doesnt seem like a matter to you =P)

Does the wastegate pipe split came standard in the 6boost single gate???

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
