Lithium

I'm fully sold on twin scrolls now, and my next stage with my Skyline will have to involve one. I'm no fabricator, but I would have thought they'd to some degree be easier? A pair of 3>1 collectors must easier to find equal paths to than a single 6>1 in a tight engine bay I would have thought?

Awesome it would be good to see it if its possible to go that high. The S368s aren't stupidly laggy so if you can do that then its a damn good case against using things like a GT42R. I'm used to Dynapack dynos myself - remember I backed you in another thread regarding that topic I know the Honda guys have got up over 700whp on them but those engines breathe crazily, and with a FWD (hardly any trans losses) thats around 800hp @ crank and probably near the limit... I always thought the S372 is more the 900-1000hp unit.

Awesome stuff By "1k high boost and race gas" do you mean 1000hp? I am pretty sure they are pushing it to crack 800hp compressor alone, unless you mean including nitrous oxide?

Spark plugs are new.... what gap are you running with them? The ignitor is something else which can play up, too.

This is a bit of a better one Did 7.89 @ 176mph that day too...

Where do you come up with a theory like that? The twins will have near twice the drag from cores/shafts and no less rotating mass to spin. Also you have referred to a seriously out of date top list - a few should be added: Heat Treatments - 7.57 with GT45R Godzilla Motorsport - 7.8 with GT47R GDS Motorsport - 8.02 with T51R SPL <can't remember the name - Arab guys) 8.1 with Borg Warner 88mm SpeedD - 8.2 with GT47 Sumo Power - 8.2 with T51R All single turbos...

Nice work

None at all that I am aware of, just bolted the cams in - they haven't been spun or anything. In a couple of months time when it gets a decent ECU there will probably be more work put into squeezing every last hp out of it, at this stage it was to get it running and running with respectable power.

Well a mates R32 GTR just came off the dyno with its .82a/r GT3582R. Its running mild upgrade cams (~260deg I believe), a home made exhaust manifold, and an old GTRLink which was proven to start wrecking the party as the revs and power levels started going up. The crappy old link has a 2.5bar map limit so tuning was finished at 21psi. The car made 379kw @ wheels on 21psi with full boost reached around 4300rpm, sounds fantastic - hoping to go for a drive in it later on today. The car will be getting a G4 Link and a retune in a couple months time, hopefully that will liven things up a bit

Man with something like the engine from the RIPS 240Z in that, that thing would be absolutely mental. Its PB is a very high 8 iirc.

Yeah x2, Superchargers are old basic technology - they have a perception of better torque down low but equal flowing supercharger vs. turbo, turbo wins out every time imho. They're kind of entertaining to drive though haha

Hmm that GCG high flow looks quite laggy to me. Here is the only dyno plot I have with an overlay of my stock turbo (dyno tuned on ~11psi) and my GT30R - unfortunately I had a few issues with tune and boost control (or the lack thereof) so its not the most flattering at all but you get the gist of it. This is a GT30R on around 1.1bar running a lazy internal gate actuator, so the wastegate initially creeps open at around 12psi then once it reaches 1bar it kindof wavers up and down. Now if I am reading it rightly, despite needing a retune and decent boost control the .82a/r GT3076R (which really shoots for a higher power level than the GCG high flow) also spools better and makes better power for similar boost.

I wouldn't even consider one unless someone/a few people actually got some tangible results from them in a street/track car which indicated they are even half up to the hype. At least here they are at least as expensive as a Garrett equivalent and nothing I have seen so far indicate they do anything more than at best compare with the Garrett ball bearing. They seem good at high boost levels, but considering most people with RBs tend to lean more towards 1.4-1.6bar tops on street cars thats a complete waste of time. Bullseye piss me off as they do interesting turbos but then do completely biased comparisons to make their options look better than Garrett ones by using two turbos which are in fact completely incomparable specs and then draw strange conclusions from it. If they just showed things as they were I'd probably be less dubious of them, though perhaps if they did then the turbos wouldn't necessarily seem as viable.

The pink one or the white one??

RB30 gives RB26 a 4 second head start and goes for it for under half of the dragstrip and the RB26 won = RB30 gave RB26 a little too much of a headstart?

Congrats man I'm sure a lot of the 12s 2WD guys here have either not done one themselves, or done it so long ago that they forgot how cool it is but I did my first 12 at the start of this summer and I was over the moon!

We'll definitely sort that out - possibly sooner rather than later as it seems the reliable daily driver (my second one in just over 6 months) seems it may have decided to carnage itself so Moby will AGAIN be relegated to daily driver duties. If thats the case, I'll be down in Welly sooner rather than later to get woman. With the mixture of turbo whistle and PE2 sweetness the Skyline would go down a treat in a tunnel. Hell a road with building on either side is pretty awesome

Care to share any? I've seen hardly any GT4088R dyno results on RBs, the only RB26 one I have seen was on one running a completely stock RB26 in an R32 GTRc and the spool wasn't too bad considering. If I remember rightly it was up around 25psi by 4700rpm and the car ran in the high 10s at over 130mph.

I bought my car as a fresh import from Japan and it came with a "Momo Corsa" stainless exhaust which is an interesting piece of work - I have never seen another of the same type and haven't been able to find any evidence whatsoever of it on the net. It had "MomoCorsa" etched on the muffler with a JASMA badge underneath. The rear muffler at least is completely straight through and it was a nice smooth quiet sounding exhaust - like substantially quieter than things like the Trust PE2 etc. The car performed really well with it but I was suspicious of its flow given how quiet it was, and the roar it would get on at high revs/boost really made it hard to be sure whether or not it was being restrictive. Bare in mind this isn't a filter and exhaust setup, I run up to 18psi through a Garrett GT3076R on an RB25. It was tested at 84db at 3500rpm with no cat installed at an arranged exhaust volume testing day - a factory Falcon XR8 tested higher!! It was very cool having such a quick and quiet car but it really barely sounded like a Skyline at idle and cruise and kindof annoyed me after a while to be honest - haha. I have since removed it and have a Trust PE2 exhaust on it now, and it sounds really nice at idle and light acceleration without being too loud - enough to let yourself and others know you are driving a sweet RB powered thing but nothing to make people cringe or complain. It is substantially louder than the Momo Corsa but I get the sensation that above 6000rpm on >1bar of boost it seems to feel freer, whether thats due to the awesome howl it gets on at those revs or some other placebo style effect I don't know - but I like it much more. Here's a pic of it when I removed it last week (had been on the car for possibly 100,000km so a bit dirty haha): And video clip of it on the dyno (first run is from the exhaust side - can hear it idle all the way to full power):

You make me happy

Nah, it belongs to Joe Kyle (aka Yoda) - a lad who runs his own shop in West Auckland and been around with that car for ages. If I remember rightly it runs a fully built stock displacement RB26DET with a T51R SPL on pump gas and full normal street tyres, he's not a forum goer to my knowledge or anything but its a very very tough streeter.

Yeah I agree with the old not meaning bad sentiment, and on paper I overall prefer the GT4088R though I have to admit that the only car I have been going in which had a T04Z on it blew me away.... once it was on steam (quite early, more so than the dyno could suggest) it was incredibly responsive and generally grunty. I have been wanting to see how a GT4088R (I will do it eventually if possible) runs on an RB but on paper they look like a fine piece of work. Saft knows I am chomping at the bit to see one going and is surely aware he is teasing me by doing this, even though I think 11.35mm lift 280deg cams are probably overkill for such a setup. Whatever happened to the 272 setup you initially mentioned, man? Some of the Supra circles are starting to convert from PT67-DBB type setups (ie, T04Z) to GT4088Rs on .95 and 1.06a/r turbine housings and are finding the cars much more fun/pleasant to drive. The power results sound like they come out much of a muchness however, and the main cases where the T04Zs get the nod is the fact that they are a little cheaper. Saft actually has the GT4088R in his hot little hand, so aside from the crazy cams I think its the obvious choice. In all honesty I don't think a 280/11.35deg cam with any turbo setup is going to make for the most lovely street car, unless by street car you mean you intend on coming down to Palmy to do some laps of the square and confuse the rotor skanks

Use the GT2540s, give the GT4088R to me... I won't fluff around making my mind up, I'd just put it on because someone bloody has to

Very nice, love the styling and the wheel choice is hot. Not too sure of the Maxima (!?) Nissan badge in the front though.... Very similar style to a mate of mine's old R33:
