So awsome to see Real St back with content. One of the most under rated channels. Would love to see alot more tests
please test the 7475, 7675 and the 8085
Yep I wanna see all those and the 72 also all next gen’s
a 68mm turbo shootout would be nice to see. Garrett vs Precision vs Borg Warner
This needs to happen
Please test the 6466 gen 2 Vs 6466 nextgen
Awesome testing, though would have been good to see the EMAP data from the 7275 as well - if anything this kinda makes the NG 6870 seem less appealing than I thought it might be as that EMAP is really taking off before you are even sending it and the amount more power the 7275 made at the same boost target kinda nods to that.
I suspect a LOT of people (definitely myself) would be super interested to see the Xona XRE6869S tested against the 6870, the Xonas seem to be awesome at low EMAP and for quite a while have seemed like the only thing that could threaten Precision in the 68mm street turbo world
Appreciate the time put into the test and recap! Would really like to see the new Xona 68mm vs the 6870NG, but in a v-band configuration. The Xona UHF wheel tends to be able to get away with/prefer a smaller than typical AR as well, which could add a variable but maybe worth considering
Please test the new Borg Warner SX-R series turbos 🙏🏽
precision is hot garbage ! every big Co is trying so hard to sale em. Borg FTW !
@NimaSomeh the fastest cars in the world run precision......lmfao
@@tonymiller6255I bought a brand new 6466 shit was smoking like mofo out of the box, got an e-mail from them saying we fked up a batch of turbos, please send your turbo back, its kinda fked up when it costs a 1000$ to ship it from where I am. never had problems with Gareth or Borg. they can be the fastest but I cant rebuild a turbo every week. so hot garbage.
@@NimaSomeh trust me when I say I've spent 25k on their turbos over the last few years, and they have been flawless. Sorry you had a bad time. Doesn't change the fact that they are in the fastest cars on the planet
Need more of these asap!
Lol everyone is asking for different turbos. This is a mid sized turbo on a mid sized 3.0L i6. It can't get more applicable than that. Scale it down for a smaller motor or up for a larger gen 2vsng
Does the S cover vs H cover change the flow/power output capabilities? 2.5” vs 3”?
What was the turbine housing on the 7275 to end up when a 1.7:1 drive pressure ratio?
Great video
I would love to see a twin charged 2JZ setup with a Dart block/wet billet, TVS 1900 blower and something like a 8685 next gen compound setup. Lag-less low end with legendary top end. Modest street cams like some GSC S1 cams, Turbosmart E-gate, Nexus R5, TB in intake for boost by speed, water to air intercooler with interchiller, water injection, vvt-i to get an 2024 ultimate response setup. SP did an ultimate sequential Supra back in 2010, it would be nice to see where we are at now in terms of what can be done with today's tech. OR SKIP all that $#!* and make a rocket anti-lag kit for a PTE 9814 XPR NextGen Turbo and go hunting TT Vipers and TT Hurrican's with it. Maybe a world record or two.
6875 next gen? Which spec exhaust housing was tested?
Please test 7675 Gen 2 vs NG 8080 and NG 8085. Lots of people using 7675 Gen 2 are ready to upgrade
Could you please kindly show more data from logs? for example not only boost backpressure, but also coolant pressurem, VE and turbo rpm? Also if its not a problem - spark advance and current AFR. cheers from fellow car entusiast lol
Literally the last clip of the video shows all of that 😂😂😂
Hell yeah! Sub gang, first.
This is a ton of great info!!!
Awesome! We appreciate you, thank you!
Can you share the back pressure log of the 7275 with the 1.0 AR? Also maybe some tests with a forged 2jz but stock bore X stroke.😊
What was the Emap with the 7275?
Thanks guys! awesome content.. 7275 makes 1000hp approximately 250rpm earlier :O, what was the turbine housing a/r of 7275? Waiting for more engine dyno videos.
At what boost pressure?
@@CP110target pressure 40psi
Something about a glowing red hot header I think can make almost anyone feel giddy inside
I showed my girl and she rolled her eyes but I agree with you
Cool test.
I wonder if response could be traced with a realistic (much faster) dyno ramp.
Would like to see 7275 next gen vs 7480 next gen
Can you please test the 6670ng?
I wanna see how the new next gen 6885 does. Thinking about slapping one on my 3 rotor rx7.
I just want to see one of their new turbos with the 85 turbine wheel.
Put a Garrett and Apex turbo to compare.
I think it was a problem in the boost control in the comparasion. Target boost means that the measurement of both turbos are at the same target boost and the boost control adjust the boost.Gen2 has less boost but also less back pressure witch means that the wastegate was more open.
maybe it would have been fair just doing open loop and not targeting a specific boost then ?
yeah should adjust boost control so that both turbos would run flat 40psi the whole way through. but imo both turbos are maxed out either way since back pressure is nearly double and engines efficiency has gone to shit
It is normal for smal turbos to have double even 3 times more back pressure than the boost. The boost control operates on the hot gases release from wastegate to achive the target boost. Depending on the engine configuration there is more or less negative effect from the back pressure on the engine power. The sure is that less back pressure makes more power. In the video when show the dyno datas gen2 has at 7500-8000 55-58 psi back pressure witch is less than the 65 psi has the next gen at the same rpm. this also efect the final boost between the 2 turbos.
Good test data. But the boost control needs to be fine-tuned. the 40 psi target must be met. Also, the 276 camshaft on the exhaust kills torque after 6600 rpm. 272 with an overlap of 0.9 mm will be much better.
I'd love to see the results of a 6875 vs the 7275. I'd love to see how much quicker the 6875 spools!
I would love love love to see a pte6870 gen2 vs a pte6670 nextgen❤❤❤❤❤
Should have overlay the next gen 68mm vs the next gen 72mm… curious on spol difference…either way great video 👍 🍻
make a video about that emu pro i see u are using
I'd like to see something a little crazy with the 2j platform like maybe back to a twin turbo setup with tubular style turbo manifold. Dividing the front 3 cylinders and the rear 3 cylinders...I'd like to see how it will make the power
People have done twins to single comparisons before, all the tests I've seen a correctly sized big single will outperform correctly sized twins in response and power output.
Please do 6670 nextgen test
Does air fuel ratio change when you change turbos or can you just switch turbos?
Depends on ECU used. Some yes, others no.
First apples to apples test on the internet
BW SX-R turbos on a K series. K20 ideally.
Why didn't they just called it gen3? Why would anyone after 2 go to "next"? Just make no sense o.O
I really wanna see what the next gen 7675 and 8385 will do!
How do these Next Gen turbos compare to the Next Gen R turbos in similar size?
Say Gen 2 7275 vs Gen R 7385?
Those two are pretty different not only in turbine sizing, but in compressor sizing as well. I think a good comparison would be in that 7385 next gen vs 7385 next gen r. For sure something we want to try in the future!
@@realstreetperformance yes! Looking forward to this. Had no idea that there was a next gen 7385...
Curious what a/R size was used on three turbos?
1.0
@@SPTuning awesome, same size so basically no difference in a/r which makes a great comparison. Great work!
@@bm3-shahsmachineshop thank you!
Where is jay? Not the same!
How long will it last before a rebuild 👀
Thats for Garrett owners too worry about.
I mean yeah dude it did what they said it was gonna do... just a little bit more efficient and a little more power... cool
So actually gen 2 failed to maintain 40psi and next gen also.
Test would be even better if you could ran boost which these turbos could maintain through all rpm. Like 31psi for both. That would show true difference in efficiency and power since not everyone actually pushes their turbos to "out of breath scenario"
Seems like if you want 1000whp to last forever with decent spool up 7275 it is
8385 next gen @ 50psi please
I just realized i don't actually understand backpressure
93oct and NA how much HP
Great question. I would love to do an NA 2JZ video, starting with pump gas, then E85, then Methanol, maybe some Nitro!
Test some turbonetics turbos please
why, they dont make any power.
@@TurboVisBits still want to see it
I doubt realstreet could benefit from testing garbage tech. Maybe if they made a side channel for vintage parts.
@@Craigineering yeah
Test the g30 vs g35
I didnt know turbos had generations like graphics cards
sportsman 7675 vs 7685 🙏
6262 vs g35-900
why dont you show the max power then instead of just saying that the turbos can do more, nearly double back pressure looks to me that the turbos are tapped out anyways
So what we are trying to demonstrate is a reasonable state of hard usage by one of our customers.
A turbo manufacturer is functionally giving a “maximum-achievable-airflow” * energy content of fuel = power in perfect circumstances -sort of answer.
A 40psi, 1,000hp usage of a 6870 likely envelops probably a good 96% of the people who we expect to buy this turbo.
While we are able to drive a system harder, and believe that there are times for that, when we’re trying to compare products, we feel like someone being able to relate the data to their own engines is more important than breaking the internet (or more likely breaking more parts. 😅)
There’s more to it than backpressure. If you don’t like the eMap vs iMap, use a larger housing.
@@Craigineering larger housing wont do you much good if the turbine wont flow more.
Nitrometh and boost
Test a coyote with 6266s , 6466s and 6870s
7685 gen 2 vs 7685 next gen
Test next Gen 8385,8685
Pulsar turbos
This is weak, where is the overlay from the 72 with the 68. That is what people want to see.
Hey good afternoon. Our main focus of this video in particular was to over lay the 68s, but I agree the 68 and 72 overlay will be a helpful graph to show. We will have that on our website's blog posts in the next few days. You can find all of our written blog posts using the link below:

Thanks for watching
Can you overlay the 6870 and 7275 dyno graph. Would love to see that
@@realstreetperformance any eta on when this info will be added to the website? Currently looking to get a turbo and trying to decide between the 6879 vs 7275. Thanks in advance
Looks like they copied Borgs SXE Line
Bro next time don’t wear the glasses please, I know you trying to look smarter but not a good look for this. They don’t even look medicated lol
Hey good afternoon. These are my actual prescription glasses. My eyes get dried out from my contact lenses and I need to switch to glasses at times.
What are you doing with the fueling? You can't just add more air and not add fuel??
Great video
