Detailed blog post: www.realstreetperformance.com...
Precision Turbo’s 6870 Turbocharger Family has been widely used by the aftermarket and racing community since its release late in 2014 as a second generation (a.k.a. “Gen 2” or “G2”) product line. New for February 2024, the long-anticipated update for the 6870 to Precision’s Next Generation (a.k.a. “Next Gen” or “NG”) compressor wheel technology.
We tested these two turbos on our engine dyno to give you accurate data.
Peak Power:
6870 Gen 2: 1,043HP
6870 Next Gen: 1,074HP
6870 Next Gen Redline Power: 1067HP at 8100rpm
6870 Gen 2 Redline Power: 1002HP at 8100rpm

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

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.

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.

@user-rh4jp5gw3y 4 ай бұрын

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.

@Jamxknife 4 ай бұрын

maybe it would have been fair just doing open loop and not targeting a specific boost then ?

@tsdyno 4 ай бұрын

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

@user-rh4jp5gw3y 4 ай бұрын

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.

@lamazver 2 ай бұрын

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"

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. 😅)
