603.5 WHP and 546.2 lbft WTQ.
34 PSI Peak Boost at 4500 Rpm.
Rewatching and listening the melody from this machine, my block is almost done, hopefuly by november or dec my car its out, did a T51R conversion on my PTE6062...regards brother!✌️
My tuner told me to get the G30-770, goals for now is 500whp+ with room for growth up to 600whp+
sounds like a space ship!
Hi! I wanted to ask if you recall your g30-770 setup sounding anything like this setup. I saw you’ve ran both turbos before. Also, what do you think about the g30-900?
Asking because I’m about to pull the trigger on my turbo kit with the 770 this month as it’s on sale until 11/30 😅.
I’m on a 2023 VB but I’m hoping I make similar power to what you posted in the past (maybe a lil less because this platform is limited in fueling right now)
I love your car build and videos. Thanks for your time :)
Sorry for the late response on this. If by sound you mean the whistle on spool up, then yes, all G-series turbos have them. I would say go for the G-series turbos from Garrett only if you intend on running them under 32 PSI. They tend to overspeed easily and operate off-map at high boost, which causes them to fail easily. Currently running a p6466. Can give you many more details if you would like on email /WhatsApp / Instagram DM cause there isn't much space here.
Thank you for your kind comments!
@@ib.i.b awesome thanks so much! You’re not the first person to suggest looking at alternative turbos.
I don’t think the VB platform is developed enough to support 35psi builds as the car only came out last year.
I’d love to talk to you more, what is your IG? Thanks much :)
@@luvhcchris it's the same @ as my TH-cam. It's ib.i.b
@@ib.i.bthank you! I’ve followed and reached out via ig.
Nice. Didn't know that was your car in the Sam Performance videos
Thanks yes it was Sam who did all the work really. We are real fortunate to have access to his experience and expertise on Subarus
Nice 👍 , but almost same results as g30-770 that would have better response .
It was on half load in the video...big difference between this and the g30-770. Would make 650 whp easy if dialled up and if the wastegate dumps externally, as opposed to back into the downpipe the way it's set up now. Also I'm using restrictive headers with 39mm primaries that don't flow high up top as opposed to Zuhair's car equipped with headers that have 42 mm primaries. Ask Sam Badawi. Ignition timing is also very conservative.
@@ib.i.b yeah 👍, you are right .
@@ahmedibrahim-ok8rh I specifically asked for a 600 whp limit and focus on the car being setup as quiet as possible, and Sam delivered well on that
@@ib.i.b yes i see the turbo is suitable for the engine size , is it the same size (turbine&compressor) as the old gtx3576 !? What is your daily setting & with which fuel ?
@@ahmedibrahim-ok8rh if you study the pressure ratios and mass flow rates etc on the compressor and turbine maps (which I did before deciding on the turbo setup) you will see that the turbo is more equivalent to the gen 2 gtx3582r, only differing in that the 0.83 A/R turbine housing is 4% more efficient, flows 3 lb/min more for the same A/R, and the compressor operates 7% more efficiently at the choke line if you operate at a absolute pressure ratio of 3.2. in short, if someone concludes that this turbo is equivalent to the gtx3576r, they can do so only by virtue of the compressor exducer size of 76mm. Anyway there is a lot more to be said to prove this, which is hard to type out here using my phone lol.
Is this a 2.0 or a 2.5l? nice choo choo sounds, and spool awesome as well!
Thatnk you! It's a 2.5L, and now runs a precision 6466. Power output at 732 whp now
@@ib.i.b why you change it on Precision?
@@spf1620 I felt it was better than Garrett
What size housing did you use 0.83?
Yes when I had the G35-900, it was a 0.83A/R. Now withe the P6466 it's a 0.82
Did you have a Turbo Speed Gauge on the Garrett? What were the RPM's?
Nope I didn't, but I can tell you for certain that the turbos oversped and I blew 2 g35-900s over a span of 4000 kms. They don't like 37 psi at 8300 rpm for sure. The precision 6466 I have now is a beast and performs way better.
@@ib.i.b what power did they make at 37psi I have one on a sr20det stroker motor was going to turn up to 34 psi ish
@@scubagto420 these turbos have really slender shafts and tend to go into over speed due to their spool characteristics, what I learnt is that with my setup, anything over 32psi of boost would see failure after 1000 miles of use. I have switched to a precision 6466 and it takes 37 psi all day. I'm putting down 748 WHP on pump gas and methanol
very nice sounds ❤😊
Thank you, it's a lot of fun too! Have more recent content on my insta, including full boost pulls @ib.i.b
@@ib.i.b ok i'll check your insta profile.. i have got a 1.4 tsi 160 hp scirocco and wanna upgrade my turbo. im stuck between g25-550 and 660. what do you think about this turbo's?
@@ib.i.b HI there! I have been following your build and have to say amazing! I'm currently on a g30-770 (after the g25-660 failed on me very early on)
I'm thinking of making the switch to precision turbo's like you have
What would be the ideal equivalent of the precision turbo to the g30-770 in terms of power and spool?
This is on a 2.1 stroker EJ207 engine
Thanks
@@zaakirwahab9023 Hey Zakir, salaam and Ramadan Kareem. Yeah sadly I've had 2 g35-900s fail prematurely at ~1500 km of use, and I know others with failed g35-1050s. They're great turbos but because of their high efficiency compressor wheel designs, they easily operate off-map above 30 - 32 psi on an EJ 257 above 6000 rpm.
For your application where you seek something similar to the g30-770, I would recommend a p6262 with the v-band-v-band 0.82 AR turbine housing
@ib.i.b wa salaam and Ramadan kareem to you too!
Jzkl for the response
Yeah, was quite shocked when the turbo failed and only after doing a bit of reading that these failures were seeming to be more common than what we would like.
Looking at the 6062 as well since I have the EJ207 (so don't have 2.5 litres to help with spool..lol)
Would you know if the 6262 would be very laggy?
What size housing? How does it compare to GTX3582?
At what rpm do you get full boost at? Heard these new Garrett turbos open up to full boost closer to stock turbos
Marselino, full boost is 34 PSI at 4580 rpm, so yes it spools up real early!
@Vladamir kzque 0.83 A/R when i had the Garrett G35-900 and now 0.82 A/R with the precision 6466
@Vladamir kzque they both spool the same honestly, maybe the 6466 hits peak boost around 100 rpm later but the difference is negligible
@@ib.i.b Why did you switch, if you don't mind?
@@linkinparkdrift from Garrett to Precision?
G series are the best💪 I'll shoot for 550 to 600+, my tuner told me to go with the G30-770, how much power i can get with the 770 or what is the max?
It all depends on what fuel you intend to use, your basic supporting mods, i.e. what manifold, injectors, compression ratio, cams, etc you're running. What is your basic setup on the engine and for fuelling?
@@ib.i.b the build plan is, closed deck, stock heads, ported some machining, injectors between 1300 or 1700, radium in tank fuel pump hanger with lwire controller, ets rotated, debating between g30-770 or the G30-900. ETS rotated with V2 header vband, ETS 3.5 intercooler, speed density Tial bov. Stock intake manifold.
@@TheE3R 1300s suitable for up to 750 whp on pump gas. 1700s if you're planning to run E85. G30-900 would be a better choice compared with g30-770 for your power goals. In my personal opinion, go for the precision 6266 or 6466 instead, but that's just based on my personal experience and choice. Go for a surge tank setup and -8AN fuel supply lines and -6AN return lines. Fuel rails too. The rest seem to be ok. Not a fan of closed deck blocks as they run hotter. Go for Darton sleeves and Oringed head
@@ib.i.b very informative and I appreciate for that info, i forgot to mention, not planning to use my car for race or track, just my weekend cruising and be able to give it some hard pulls once and a while without have to worry of breking anything.
@@TheE3R reach out to me on Instagram DM @ibrahim_8229 or ibrahim.i.butt at Gmail. There is a lot more I wanted to say and it's easier said on VNs
Is it a direct port aquamist system you are running ? Great power you Got 💪🏻
Thank you! Not direct port on each intake manifold runner if that's what you're referring to. Two nozzles upstream of the throttle body, suitably spaced of course.
@@ib.i.b Amazin power 👍🏻👍🏻
@@Skassa-garage she now makes 732 whp on a precision 6466, pump gas 93 and meth
@@ib.i.b i have also purchased a 6466 for my trackday hawkeye build , and a directport aquamist setup , With full supporting mods , i just need the time in the shop to finish my own build ✌🏻
@@Skassa-garage that's great! If you're looking for big power, I recommend the Process West intake manifold. If you retain the stock manifold, expect 670 whp. Yes the process west manifold adds 9-10% power
Was your G35 modified with t51r mod, or does it sounds like that out of the box? Thanks!
Sounds like that out of the box
Do you have any more information about the lift off surge?
Yes it's caused by a stiffer than ideal spring on a tial q50 BOV, plus some schwifty throttle control from my end
Quality turbo?
It's a good turbo, but It doesn't like to be run consistently above 32 psi. I swapped it out to a precision 6466 and now make 732 whp
@@ib.i.b iam thinking about 6466 at 32psi more power?
What Bov or is that turbo flutter
I'm running a Tial Q 50 mm BOV, but yes that's liftoff surge you're hearing on partial throttle. Doesn't do that on full throttle runs though, just vents through the BOV like it should.
@@ib.i.b yea I have a 700whp gc8 with a gtx3582 gen2 that whistles like that but dosnt flutter like that
@@nztrucker1542 what BOV are you using? Would love to see videos of it, wow 700whp is a lot
@@ib.i.b yea I have videos of it on other TH-cam accounts cant remember what there called. Yep it's a 10second daily driver hopefully 9second daily this year . I'm running a gfb bov was recommended as the best one.
@@ib.i.b th-cam.com/video/ngZ6SvMqWL4/w-d-xo.html
wow that thing is slow to spool up huh?
Yes a bit 🤣
@@ib.i.b lol pretty dope nonetheless
@@TENNESSEETRACKHAWK she now puts down a consistent 732 WHP and , 620 WTQ, so yes... Pretty dope indeed :)
@@ib.i.b thats quick for sure. im about to put a big turbo on my Golf R I know the spool will be slower but I dont care its a fair trade off
@@TENNESSEETRACKHAWK that's alright, A 560-600 whp golf R will likely toast a 750 WHP STI, so you're good! The DSG makes a world of difference
Which BOV are you using? HKS?
Tial q50 with an 11 psi spring
@@ib.i.b huh?? You're confusing the external wastegate with the BOV
@@neuspeed79 lol and you're confusing me for a noob 😊 The BOV is a tial q50 with the 11 psi spring and the wastegate is a 44 mm tial MVR with springs configured for a 21 psi base boost target.
@@ib.i.b Plot twist: I'm the noob!! 🤣 I didn't know Tial made BOVs 😓 What made you choose that specific model?
@@neuspeed79 lol it's all good, no worries, I still have a lot to learn myself. I chose the Q50 because it was easily available, fairly priced, and a good brand. I wasn't necessarily after a particular sound on blowoff at the time. (But I secretly want to go with no BOV to make stututu noises 😈)
How much hp you think that Turbo will make on 3.0 on pump gas
I wouldn't imagine it would be a good idea to run at 3.0 bar with only pump gas. My newer winter tune @2.5 bar allows for 656 whp with pump gas and methanol
Sorry about that ibment to say 3.0 litter. I got a 335i
@@ram00sa00 is it easy to convert from the stock twin setup to a large single turbo? If so, go for it. You should see around 650-700 whp on pump gas with the 3.0. personally, I would recommend smaller twin turbos, say the g25-550
Most of the tuners told me to go bigger turbo on a lower boost level to reduce knock
@@ram00sa00 there is a good amount of truth to that only in the sense that you will need to run lower boost levels to get a given airflow on a bigger turbo vs a smaller turbo, meaning your intercooler will need to do less work. However your power band is pretty narrow with a bigger turbo. You can solve this with a good intercooler and/or methanol injection.
2.0 or 2.5 engine?
2.5
That looks laggy asf lol
What the spool time on this turbo exactly the rpm?
It's all dependent on what intake manifold, intercooler, peak boost target and Turbine housing A/R you're running. Also significant are boost tamp characteristics in the tune. You could have peak boost at 4000 rpm, or at 5000 rpm dependant on all these factors
