Last I heard it was still in the build - hence asking about the upgrade
-
So the Black hasn't actually been run yet, or won't be?
-
That twin scroll thing is one of the things that irks me a bit about them too - though there are options to go with them, they just aren't one of their staple things. What do you have now Tonba, and what are you aiming for?
-
Someone I know had a twin scroll T04Z but wants similar power with better response for an RB30..... I was thinking a 0.84 6266, any thoughts? Sent from my GT-I9505 using Tapatalk

Building An Rb26 For Response....
Lithium replied to Antimatter's topic in Engines & Forced Induction
Holy crap. I've been in a GTR running twice that power with the original block - it must be in pieces -
What fuel?

Haha yeah to be honest I'd like to know myself, but there is no way I am going to try and convince someone else that it's a good idea - it's one of the reasons I am so conservative when I try and predict an outcome.... don't want to tell someone to expect a result and have them spend weeks and thousands of dollars on that basis only to fall short. A recurring thought that this makes me feel PARTICULARLY like dwelling on now is that it probably wouldn't be stupidly hard to design a cast manifold which doesn't look high key but provides an external wastegate port and a place to mount a large turbo without breaking away from the stock look. I am going be involved with the build of a Supra aiming at 500+rwkw using an FSR manifold and a Precision 6466.

What am I missing here - what's going on a stock manifold? Edit: OH Crap! I didn't see JetR31 saying stock manifold, my brain fully blocked that concept even when he said low mount. WTF?? You're worried about the GT3794R's turbine causing excessive exhaust pressure and you're running the stock manifold? Ummm...... I'm very prepared to eat my hat if I get proven wrong here, but this doesn't sound like a good idea at all. Good spotting GTScoTT (or poor spotting by me haha). What kind of power are you after man?
-
With cams or a stock head? Compare power levels, not boost numbers to get an idea of what the turbo is usefully flowing
-
Surely if these guys can fit two down low in an R35, fitting a single Super99 HTZ down low in an RB-based Skyline shouldn't be too hard? Mayne I am being optimistic? http://www.extremeturbosystems.com/ETS-Nissan-GT-R-Little-Hero-Super-99-Turbo-Kit.html

I don't think they tend to hold that into the high rpm with unmodded 16G6s, its more like they peak at 30psi and it bleeds back to mid/low 20s. Bare in mind that Stao's car has bigger cams etc as well, so will be moving more air at a given boost level at high rpm than a typical stock 2litre. In saying that, it seems that the 16G6s are seriously underestimated by a lot of people - as I've said in another thread, we easily ran out of injector (at 55psi base pressure on ID1000s with E85) using a Kando TD05 16G6 (TD06 comp housing version) at 20psi, enough power to get ~120mph trap speeds and the turbo still has more to give. The SS2 is clearly a bigger higher flowing unit, though.
-
I don't think there is a housing which will cause that issue - when I had a .63 housing on mine I struggled to keep it UNDER that boost level, it was hitting 20psi by 5700rpm and trying to climb hard. The only reason the turbo itself would not be able to hold boost (assuming it's healthy) is if it is struggling to keep up with the airflow requirements of that engine at that boost level. Even a .63 GT3076R shouldn't have issues, really the compressor and turbine should be able to hold 20+psi "all in" so if it's not holding, it will be something to do with the setup - wastegate/boost controller/boost leak/exhaust leak/something...

Have a look around, HTA may be marginally more expensive but again if you need to get the whole bunch Bri73y might be selling a whole HTA combo which may be more convenient Sent from my GT-I9505 using Tapatalk
-
In the US and other places where people have used both (not specifically in the car) the consensus seems to be the HTA usually makes similar power but much more responsive. Sent from my GT-I9505 using Tapatalk

Oh because there hasn't been any FP pr0n posted for a while, there are about 3 R35 GTRs (that I know of) now running ETS' "Little hero" turbo kit which consists of twin Super 99HTZs, and a couple of drag EVOs both aiming for the late model EVO record are running the same turbo in single form. One of the R35s is based in Bahrain and did an 8.2 on low boost on it's first run, then in the second run destroyed the gearbox - but set the 60ft record for R35 GTRs on it's way to destruction.... with the kind of power it's capable of making (ie, 1800-2000whp) with that 60ft time (1.26) I suspect it's capable of in the 7.5-7.8 range going. Here's one of the R35s doing 1/4 mile roll racing from 60mph at TX2K14 in Texas last week, it started off on "low" boost (dyno couldn't hold over 30psi) and checked and adjusted tune and raised it between runs... ended up hitting 196mph! They "only" reached 35psi, so definitely more in the bag....

Bri73y's HTA3076 is a .82a/r housing - not sure if you have seen 34GeeTeeTee's result, but they are arguably the perfect middle of the road turbo for an RB25, spool closer to a GT3071R than a normal GT3076R and make pretty huge power Check out his result etc here: http://www.skylinesaustralia.com/forums/topic/426059-forced-performance-hta-turbos/ Mat's (and Bri73y's for that matter) power level in a light car should be good for 10s down the 1/4 "all in".
-
OK, a manual does make it a little trickier - you would have a bit more issue spooling the larger turbos mentioned and keeping them on steam without revving the hell out of it. Buy Bri73y's GT3076R HTA, wastegate and manifold....
-
It's just you.
-
Yep fair enough, if you are going to be pushing it hard then the Super94 definitely makes more sense. Would be awesome to see one on an RB30, would be an absolute weapon! Sent from my GT-I9505 using Tapatalk

Why such low power target? If its a drag car, go nuts! It makes no sense to me to try and keep it responsive if you are going to be launching with launch control etc, you'll just end up having to upgrade when you hit a wall. As much as I'd like to recommend all sorts of fancy things, I reckon you'll end up looking to upgrade... start off with the cheapest most reliable thing that will do that power easily and then you don't loose too much if/when you need to upgrade. I personally would go the Hypergear SLSS2 turbo to get started, it will make the power and not be a lag monster and isn't overly expensive... then depending on how tough you build things and how long it takes to grow a pair - put a FP Super99 HTZ (or at least a Precision 6466) on it... you are going to have launch control, and always be up in the revs, you don't want to be changing turbos all the time so you can grow into it
-
^ I would guess the same, but why do you need to run the T04S housing? The Super-series housing isn't THAT much bigger afaik? And on the flipside, the GT3794R HTA doesn't flow THAT much less if you needed to run that... though the Supers are probably a bit stronger.
-

^ what he said - maybe not SHORT gearing, but the right gearing and stall setup. You haven't said what times you're after? Strictly speaking drags are drags - for the most part (aside from gearing) you'll be setting the car up similar to get a quick 1/8th mile time as you would for a 1/4 mile time.... as the most important parts of the run are firstly the first 60ft, then the following 600ft will be where you win or lose. Beyond that point you're ultimately trying to maintain the progress you've made up to that point, the hardest stuff has already been done. The fastest 1/8th miles cars are also the fastest 1/4 mile cars, and vice versa So - if you want it semi usable on the road, but very quick over the 1/8th etc... Precision 6466, auto, NOS. Or more details on the setup and targets otherwise there is nothing stopping us from saying "Powerglide, Precision 91mm Promod turbo, NOS!!"
-
I'm not talking just dynos - I am talking the fact that the HG turbo has larger wheels, on a different engine setup, not externally gated etc. There are things that will work for and against each turbo so much that you are comparing apples and oranges to find out which is the better banana. I'm not going to compare them on an Excel spreadsheet/whatever, I reckon it'll make the Hypergear look bad and in this situation I don't think that's a fair representation of what Stao has built.
-
Yes it is. At a glance it gives away near 150kw at 4000rpm! That's in the territory of twice the power at rpm you will REALLY notice it, that's not a little better. Catching up from 4000-4500rpm is where it's finally getting up to full boost. This is all subjective, if you are happy with that lag then it's a brilliant deal - but realistically, if you are asking me that question seriously... post a thread asking everyone how much time they spend driving under 4500rpm. If you happy with that lag, then pressure Mat into putting an HTA3582 onto his car and wind that up onto kill - then the lag will be more comparable, but the power won't (if his motor survives haha). Agree with most of that, which is why I said you shouldn't be comparing them - I am not knocking this HG turbo, it's a different setup altogether on a different dyno, I think you are selling BOTH turbos short in ways by comparing them. The point I disagree with is the Excel comparison, Mat's turbo would give the HG a thumping until the HG was up in the rpm. It is not the turbo to be comparing with this turbo at all - only reason it seems to make sense is the HG turbo made almost as much power (and no doubt the wheels are capable of moving more air). In my opinion it's a stupid comparison.
