Tech Talk Tuesday: What is the BEST TURBO Money can Buy!?!? 

Video sponsored by Precision Turbos....

"I know precision turbos , Changing the game with these 6 blade gen 2's " slaps the top of the turbo with 7 blades.

Solid information! Definitely enjoyed it

Great video thank for the Education

Good info fellas! Idk I have mixed reviews just from my experiences. I've heard alot of bad things about precision, yet still see it on high level cars. Yet I've had nothing but good luck with Garrett. No BOV for 20 events and still going strong... the way I see it is coming from aviation Garrett engineers turbjet/turbo prop/turbo shaft engines. So... they've got to be doing something right. Lol

I would have thought that an expert in turbos would know that closed throttle flutter is not the same as open throttle compressor surge. While similar to compressor surge, turbo flutter doesn't occur while the turbine is loaded (exhaust spinning the hot side of the turbo). It should not be referenced as “surge”. There is negligible affect or any documented or observed damage to bearings or wheels as a result of no-BOV off throttle flutter, or the “sututututu” noise you hear when throttle is closed. It’s a myth. Real compressor surge under open throttle load however, is known, observed and well documented to be potentially catastrophic. You should know the difference.

great information from the drift community

I endorse compressor surge so long as you have the pocket for the replacements.

Precision is so good, that’s why all the OE manufacturers use them… oh wait yeah 🤣🤦🏻‍♂️😴

ive had 2 6266 BBs gen2 fail on my Evo 8 @32psi had a restrictor and filter. Precision rebuilt both of them but after that Id never run another one, FP Red on my new Evo 8 now @ 38psi for 2yrs with no issues

7 BLADES

Problem is, it is all a "pi..ing" contest in regards to compressor inducer diameter. Just go way too big on volute volume in compressor housing, and you win top end power - which for some is performance. BUT that does not make for a great turbo if spool-up is sacrificed for harvesting most out of a wheel diameter. Same principle for harvesting most out of 1.5L engine when in fact you are allowed to go 3.0L. Same for compressor wheels, and when configured correct in regards to volute volume, exducer, depth etc. bigger comp. inducer wheels actually can perform quicker spool-up as the "package" is designed correctly not only for top-end power. Bigger comp. inducer moves more air per rotation, and hence requires less shaft rpm for same flow inside the compressor. Forget the marketing race/piss..g contest of inducer diameters, and focus on the application instead

The cut ins are so funny 😂

I love this video lol

Regarding: a heavier turbo shaft makes a measurable, noticeable, and significant difference based on its mass. The difference is the bearing diameter, especially in an oil film bearing. THAT will cause more drag at all times due to bigger shaft size, but something adding 1-2mm of diameter on a 70mm turbo wheel is insignificant for polar moment. I just don't think Borg-Warner prioritizes performance versus permanent longevity, and that means a more robust construction, which leads to heavier overall internals, but I don't think the shaft itself is the MASS or INERTIA issue. A Borg-Warner turbo is for life.

I just bought a Xona Rotor 9569s.

Borg & Warner and Garrett ftw. Oem reliability.

Nice. What turbocharger is suited for making 300hp for a 1.6 tdi engine ?

Which is the best value for money turbo brand? (other than Chinese Ebay Turbo's)

Watching this while im only using the standard IHI turbo🤣

I’ve never had a problem with any precision turbo or forced inductions turbo I’ve had some problems with some others not gonna mention any names but there’s a reason I bought and went back with precisions

What you think about Precision vs Mamba?

There is no such thing as "cavitation" when dealing entirely with a gas environment. "Cavitation" is when a liquid has an artificial gas cavity along its tip or trailing edge due to pressure going below vaporization temperature. Aeration is when a body doing through a liquid entrains air from the surface or other source. However, it is interesting, the concept of too many blades leading to less high-speed air grabbing by the compressor wheel. Too many blades passing by the same point in space, you are saying, find they can't grab as much air as fewer blades, due to the air not having an opportunity to "fall" into the space between blades, because there is just too many of them. That is an astute and fascinating observation, and one I have never heard anyone on any channel or manufacturer's site even discuss. Kudos for REAL WORLD EXPERIENCE trumping theory and sales hype. Let's go to the extreme: supposing the compressor had 100 blades. NOW when will the air have an opportunity to fall into the space between blades? Advantage: turbo with fewer blades.

What about Xona?

VS RACING FOR LIFE

spool difference between gtx 3582r gen2 ar 82 and pte 6466 gen2 a.r 82

What about this Pure turbos i see in a lot of videos lately?

How does Precision perform at high altitude?

Where are the side by side comparisons? Why are there no maps to help someone match the turbo?

PTE Gen 2 BB 6266 turbo needs a restrictor then? I am running it a K series engine.

If your still there, what is the correct turbo charger for a nissan frontier 2018 4.0L 6cyl. complete setup. I want to buy a turbo charger and tune it correctly for fuel efficiency. NOT HIGH SPEED, fuel efficiency thanks.

Nice vid . I would say garrett is the better of them all , bigger company better comp maps and more efficient per size of turbo compared to gen2 Percision and gen 2 Garrett.

Gotta try Garrett's new G series, they are crazy. My G30-900 in a 1.06ar spools faster then a gtx3576 in a 0.86ar with less back pressure on my n54

Since when has it been good thing to have the BOV open on idle???

As long as you don't mind chucking an exhaust wheel then Precision is a good choice

What’s a good turbo for a 2012 Mazdaspeed 3

Nobody talks about Borg Warner. I have heard they wipe the floor with any other manufacturer.

Some good info but BW EFR series trumps everything with spool alone and loves high boost. You emphasise they aren't as good twice because they are huge competitors.Precision don't have compressor maps to even compare. Smaller compressor EFRs outperform response and flow against Precision rated by HP or get close to the next size up with more efficiency....I hope it was worth it. 🤦‍♂️

Also your drain line leaving the turbo shouldnt have any kinks rule of thum no 90 angles on your turbo drain

Kupiłem 11 lat temu ten pecision turbo model 6262 na zwykłych łożyskach. Lało się od początku na spływie olejowym. Zmieniałem chyba 5 razy spływ oleju, flansze spływu itp, dalej lało spod spływu oleju. Zrobiłem nawet flanszę z o-ringiem. Nic nie pomogło. Zgłosiłem to do precision ale nic nie uzyskałem. Nie byłem z Murica😆... Wreszcie poszedłem po rozum do głowy i kupiłem oryginalnego garretta gt35dbb i go zamontowałem. 11 lat pełnego spokoju. Zero kłopotów. Precision najlepszy? Hahahaha, chyba w Murica🤣🤣🤣...

Vs racing turbos are the best bang for your buck right now besides almost all turbos are made in China anyways.

What turbocharger would you recommend to install in an Isuzu 4BD1 Isuzu engine, installed on a Land Rover Perentie?

I'm thinking about doing a twin scoll twin trubo set up in the future for my Dakota that I'm working on turning into a baja truck. I havent found much info about a twin scoll twin turbo set up. Is there some big issue I'm missing?

Pretty bias. I have experience tuning BW Garrett and precision turbos. They are all fine. Saying borgs are lazy is blatantly wrong. We've been able to get comparable spool for same pwoer levels on journal SXE borgs, vs even BB GTX turbos. Precision are pretty good but I don't like not having a compressor map to plot against a build. Not to mention empirically proven, EFRs are the absolute fastest transient (what matters in drift or circuit racing) responding turbos. If people aren't aware check out borgs matchbot to help plot your build to see what turbo fits. Of course turbos function in their efficiency range. You don't actually know precisions efficiency range, because they don't have compressor maps. Precision is fine. They had some rough history to repair when garrett stropped provided them CHRAs. You said Borgs are lazy spooling, but the EFR is empirically proven the fastest transient responding turbo on the market (of course vs whatever power application). All 3 brands are fine, your representation of the 3 brands is pretty bias. Everyone has their favorites. Garrett and Borg are tried and true and industry innovators. Borg especially. Hence see EFR used as indy series turbos.

What about xona turbo?

Very bias !!! Why not have a g35 1050 up there with the precision turbo ?

EFR

I agree precision easy keep power band rev no drop….for my experience in circuit pt5862 gen2 better than a gtx3576, pt turbo intake and exhaust balance well and price good too…

But turbo flutters good sounding

No talk of FP/Xona huh.

I can’t even afford eBay turbos, that’s sad

Theres never been any definite proof that off throttle surge causes any damage to the turbo, therefore BOV's are pointless imo. On throttle surge is a different story

The flutter shouldn’t damage the turbo AT ALL if they are ball bearings, to me it just sounds like precision’s isn’t built good

calling borgs lazy didnt grow well efrs spool fast af now

I have an 04 pathfinder 5 spd manual. What’s a long lasting turbo I should get. I’m mainly in it for long lasting engine and motor than speed

What type of alloy used? Anyone pls

Borgwarner.

What turbo do you recommend on a Scion tC 2006?

Oil restrictors are only recommended for Ball Bearing turbos. Journal bearings do not require them.

Definitely not being paid... 🤥

It just falls off....lol

How did this info age against efr black series and xona rotor uhf tuirbos?

The marketing managers only wants the hype for top-end power, just look at Garrett, suddenly the Marketing department changed the conversion factor from lbs/min flow to HP overnight dramatically upwards with the G-series. Even their distributors informs about it. It is a laugh. E.g. now a 56mm turbine exducer should do 900hp according to Garrett! (example G-30-900). Think about it .... little over a 2' pipe with 9 blades inside should flow 900hp in the exhaust. Why would anyone with a race engine attempt or claim that even with NASA rocket fuel!?! AND even the compressor wheels are mapped inside way too big volute volume compressor (large frame) housings, and then pictured and sold with normal sized housings afterwards. It is becoming same circus as the VAG emission fraud. It is all marketing to compete on the diameters which is only a factor for the marketing department, not the race teams! People who do not understand turbos, eat all the fancy headlines and "performance" punch-lines raw

Any thoughts on Comp Turbo?

Can anyone recommend me a good turbo? I have a all stock 90 talon tsi. Its got the 14b an love the out the hole power but dies once I'm up to 130. I won't my out the hole power but need way more..lol. I plan on a build list an goals are 5 to 550hp by the end. But whats the best turbo to still have some out the hole power but don't die a 5k rpms. I've heard a 20g but hear I'm gonna lose my out the hole power? Any advise would be greatly appreciated. Glad to answer any questions to help for the right turbo. An fyi..its gonna be a street car.

lol

He asked why we choose Precision Turbo, here is where i stopped the video. Let me tell you why, because the he gets the most profit from selling that garbage. Garret and Borgwarner is the only turbos you should look for.

If you've got dyno charts and went through the efforts to test them, there's no way you wouldn't include those in this video. You put in the effort to include the standard memes, let's see some effort to back up your claims

Why the hell is your intro so loud if you’re gonna talk so low

Lol. Totally bs

Ball bearings are always better.

This review sounds bias asf just my two cents

Great job comparing some old ratted out turbo to a brand new gen 2 turbo. Lmao 😂👎🏻👎🏻👎🏻👎🏻👎🏻

This has to be the worst Turbocharger video on the internet

What about xona turbo?
