NICE WORK! That vid is going to inspire much fapping over the next few days haha. Dyno plot?

Cheers for the ongoing feedback, its really interesting - sounds like a nice setup and I bet it will get real fun with a decent exhaust (and intake) manifold. Definitely not saying it isn't already, amazing power for a bolton setup Wolverine, so you are selling Micko on TS - any chance you will take a page from his book and go E85?

On E85 I can fully see them hitting 400kw, as I've already said. On pump gas, I'm pretty confident of it NOT happening. You don't need >60lb/min of flow to make that kind of power when using flash fuels though.

^ as above, can only but try. The compressor is not the only part of the equation, even if the compressor CAN move x amount of air at y amount of boost its irrelevant if either the engine, the fuel system, the other boltons, the turbine housing/wheel, or any other part of the car isn't up to supporting that power figure.

That GT3582R compressor map isn't right... see from Garrett: Either way, more than enough to way outflow the GT30 imho which makes it pointless having that much compressor imho. Again, I am not at all convinced that a GTX3076R will make any more power than a FP HTA GT3076R.

Are you talking about on the VQ? I was aiming the response at Dajae who appears to have a Skyline, wouldn't think it should have a problem there. The FP turbos have OEM Garrett housings, though as you seem to be aware all use the .70a/r comp housings. I'm not 100% sure why people are excited about the GTX3076Rs tbh. The comp wheel doesn't flow as much as a GT3582R compressor, and a back to back dyno with a GT3082R has proven them to offer no better spool. There hasn't been anything yet to make me feel like they are something special, they flow like they are a bigger than a GT3076R and spool that way too - more lag and more power are just a typical trade off. In all honesty so far I prefer the idea of a Kando T67!

The normal GT3076Rs have been pushed up past that before and made good power, but yeah they are definitely pushing shxt up a hill. I reckon the gun choice for what you're looking at doing would be a FP GT3076RHTA personally.... have a look into those while you're considering it. They are claimed as 59lb/min, which sounds underwhelming compared to the GTX but bare in mind the maximum flow is rated to whatever flow efficiency the company decide to use as a cut-off and isn't an absolute - and also Garrett themselves have ultimately said the 77mm compressor used on the GTX3076R isn't suited to the GT30 hotside by putting it on the GTX3576R, the extra flow is argueably redundant on the GT30 turbine. I think the HTA76 wheel is basically the ultimate compressor for a GT30 turbine, the most flow you could put through that turbine with better response than a normal 56trim GT3076R wheel.

I wouldn't, not unless you've seen anyone push one that hard and make that much power on a dyno type that gives results which reads in the area you aim to reach that power on. You certainly won't be getting that power from one on pump gas on any dyno, E85 or something similar would be a must. 400kw should be achieveable on E85 with a GTX3076R at least on a hub dyno, actually even potentially with a run of the mill GT3076R.

The vid actually tells very little in general, looks quite laggy in 2nd gear (though you say its not necessarily full throttle?) and breaks loose a bit in 3rd. Seems like it must go ok though, take it to the strip and point a camera at the dash

The thing I'm most interested in is where it starts building power etc, its clear that with >20psi and E85 its going to make good power - that was never the question. I'm more interested to see if its equal to or any better than a regular GT3076R in normal usage.

Hmmm that RB28 looks a bit like it could be the quicker car if you used the revs....

A mate of mine has been building his RB25 for AGES, has a PT6765 CEA for it and was aiming for around 800hp @ hubs - the 66s seem like a decent improvement too. I've prefered the HTAs up till now, still quite interested to see more PTxx66 results and see if they have made up some of the difference. Another mate has a GT3586HTA on his RB30 running >700hp @ hubs on relatively mild boost levels and E30, was held back by fuel system - was still gaining power.

The HTAs are pretty much the opposite, usually they seem to spool/respond slightly quicker than the equivalent non-"billet" wheel but still flow more... I'd say it could give pretty good results.

17psi loaded at 3800rpm-ish is actually not that flash, loading a GT3076R against a dyno like that (depending on how long you load it for) you can easily hit 17psi by 3500rpm. I've not been in or driven a car running a GTX but I'm feeling more and more like they aren't doing anything that the previous range did, GTX3071R = GT3076R, GTX3076R = GT3082R, GTX3576R = GT3582R. GTX3582R, well... they have made some huge power but there are plenty of other outfits who have been upgrading the GT35R compressor wheels which cost less.

Yeah I noticed that with the higher resolution one as well, I'd expect a normal GT3076R to at least match that on E85. A setup I think would be unreal on an RB25 would be a 6boost manifold, wastegate and a FP GT3076R HTA... probably very hard to beat.

Ah ok - if that turns out to be the case this it seems the GTX3071R is a bit like the other GTX turbos, as laggy as (or even slightly laggier) than the next size up wheel would be anyway At least it flows more, too! Can't really be compared with a T67 though, with a 6boost manifold and external it would probably improve by a few hundred rpm in spool and gain a few healthy killerwhats. Fingers crossed the latest fixes and the 25G make you happier!

Really? Its 25psi by 4000rpm, starting at 3900rpm means the turbo has less time under full load to overcome inertia

Awesome, I bet it is.... its actually roughly the area I was hoping to see, basically says that its capable of making as much as a stock RB25 with stock manifolds can. With a decent highmount and plenum I'd say the wee GTX3071R has more to offer, too. Definite win for a stock manifold setup, though

Awesome result, alright - gotta be happy with that! Looks like a wicked power delivery... must be awesome fun

That is too bloody awesome for words. Awesome build, no idea why you'd sell it- but still... congrats and good luck!

Madness, nice work.... whats the spec as raced? Any vid?

Plenty have made 500whp on normal GT3582Rs, a PT6262 is a bigger turbo again. When E85 has been involved, the 6262s have gone well north of 600whp...
