Turbo Tech - What Do The Part Numbers Mean?

Turbos are hard enough for some people to understand, and the turbo manufacturers don't make it any easier with the various naming conventions. They all seem to use a slightly different format and often use completely different measurements in their part numbers.
In this video we examine some common turbo brands like Precision, Garrett, Borg Warner, Comp Turbo and Xona Rotor. We explain what the numbers in the part numbers mean and also tell you how to convert them to one format to compare across brands.

Great stuff. Appreciate getting pure details is a straight no BS kinda style. Thanks.

[@slandrum7350]

Killer info on this channel. Keep it up this channel will boom!

[@foxairandheatinc8345]

Nice video. Good info. The compressor maps really tell you where they are the most efficient, but like you said not everyone has them available or knows how to read them.

[@idahobuckaroo8348]

Thanks for the info. Very helpful. I use compound turbos on my street setups on Cummins diesel pickups using Garrett, Borg Warner, and Spoologic turbos. Definitely helps to understand the size of your turbos. 👊

[@cecilioyruegas2097]

Thanks for the simplicity of the numbers..

[@Rhett.Castillo]

I've always wondered why there isn't a set standard within these manufacturers, in order to avoid confusion and make shopping for your specific application much easier.

[@Elver_Galarga_jugo]

If you think this is annoying, look at car audio amps

[@mikeleschber33]

Thanks for all the great info! I am looking to build my first turbo motor and seeking any info I can get.

[@mehdiidelouali2356]

Very brilliant video, keep the work up

[@rowlandbarrett3437]

Nice video, just subscribed as well. Keen to see results on the Xona Rotor

[@bryansenulis7242]

Soild info ....i didn't know how to read the compressor map until now.... thanks alot and i sub

[@sumfoo1]

There was a garret gt37 that would have been around the size of the ct3793. I’d like to hear more about those “oil less” turbos... mostly how often do they fail.

[@chrism.728]

Great content on this video!

[@robertpaasch6343]

Good video. I wish you would have went through the other popular turbocharger - Turbonetics.

[@Friendsofdonr]

Do you have any videos on the pros and cons of the t51r mod?

[@numinous4789]

That BW EFR is the nicest of the lot on the table. I love Precisions too, and they have their place. But EFRs are used in F1 racing; they are seriously next-level. Flow rate for flow rate they out-perform all other turbochargers, and they have the major heat-management advantage of both coolant and oil in the CHRA over oil-only Precisions (especially for tracking abuse as opposed to 1/4-mile use).

[@mitchellhayman381]

Bullshit

[@4door_papi]

Bull lol just run a oil cooler like alot

I get confused about all non-standard terminology in the turbo-world. I learned that the inducer and exducer are on both the compressor and the turbine side. Like in the turbocharger app. Do I need to re-learn now?

[@TylerSavin]

Without knowing too much, I consider how much exhaust gas is needed to spin the turbine blade fast enough for the compressor to actually start forced induction throughout the entire intake system, through the manifold. Find that out and you'll learn a lot about how it behaves. The larger the intake on the turbo, usually the higher horsepower you'll be able to make, but will require more exhaust gas to start building "boost" and starting forced induction.

[@kevin-jm3qb]

I wanted to disassembly my new turbo to get the turbine housing ceramic coated. anything to know or do before i remove the housing or when i install it back on?

[@darrenmcfeaters6683]

When are they going to come with execute order number for street use?

[@TheRealMichaelP]

Very informative, why do you think precision doesn’t have much information on their site? Should I stay away from their products?

[@alexsails80]

Hi. Can you help understand what Holset turbo naming means? Such as HX40M M for marine, but what else? Thanks

[@user-vs7sb9wg2r]

Maybe the 35 in GT3582R stands for 35mm diameter compressor outlet?

[@mlpellicci4258]

Can someone help my confusion? I'm looking at turbos, specifically kits using the TD06SH 25G-8.0cm and TD06SH 25G-10.0cm turbochargers. They both look good,seems the same outputs, what id be after and I understand the majority of whats going on, however I can't make sense of the -8.0 and -10.0cm on each. what does it mean? is there a difference? and is one particulary better than the other? Thanks.

[@CourtneyEdmonds]

Great video! What would be best turbo size for a twin setup on 351w with Vic Jr heads roughly? im keen to know your opinion thanks

[@philistineau]

Courtney Edmonds twin borg s366 will easily get you 1000 HP. Making that on LS engines. Popular choice.

[@jeromelevesque8330]

We could add the new Garrett g-series turbos designation, exemple : g30-770, who refer as frame size 30 and 770 hp potential

[@eriksteyn3986]

Awesome presentation! Quick one, in South Africa people says "T2 Turbo". Do you know why and what is a T2 Turbo. -E100

[@hacendiyad4454]

Hello,why the turbocharger rebuild not valid along time and not resist high temperature especially who rebuild by Chinese turbocharger spare parts ?

[@mohdhammad4786]

In Garrett turbos what means M10 or M12 written on the compressor housing?

[@Alex-pl1ye]

So whats a good size turbo for a single turbo stick mustang 5.0 ,ar. Borgwarner

[@elsaidaboyousef42]

Please explain the oil and water cycle inside a turbocharged Volvo D13 marine diesel engine

[@hoost3056]

On a something that would be more road race biased versus a drag race application, would a .68 or similar exhaust housing be better for a Coyote or Voodoo engine?

[@PalmBeachDyno]

It depends on what overall power you want but it would probably be a good move

[@mikeandNikes]

Do all company’s use the same measurements to determine the AR?

[@zeno15sti33]

I don't have the experience with turbos as you guys do but I always thought that Garretts numbers referred to the turbo inlet size.Weridly as you use precision as a reference I use Garrett, yours is more accurate 😂 In Camp Subaru we tend to run bigger AR , 80s and 100s seem common but generally not T4s tho. I'm running a Cobb 20g which is 5249 Vs my friends 3582r ,He kinda really didn't pull on me the way I thought he should have with the hp advantage. Kinda turned me off Garrett. Waiting to see there new G series on the street. Obviously other factors go into the whole thing.

[@scottsmith6571]

I’m running a 6768 hpq dbb billet on buick an 70gtq billet dbb billet on tta precision turbo

[@10R8OH]

What’s the AR on the xonarotor turbo? 1.03? And with the Precision’s in a non max effort 6R80 Gen 2 setup, what’s the best AR for the street in a 6466 .82 or .96?

[@PalmBeachDyno]

I'm running a .82 to start on the Xona and I would run the same on the Precision. I've never run larger on a Twin Turbo Coyote. I may try that with the Xona's but wanted to gather data with the .82 first.

[@jeromelevesque8330]

I have a xona 95-67 xc3 turbo with a turbine housing a/r ratio of 0.85

[@OhSoCorrina]

I have twin 6466’s .96 AR….running 6.0 LS…what’s your idea on that setup?

[@christianh.8408]

Good video, but you forgot the borgwarner k series i have an k27.2 for example. The 2 stands for the turbo center section size, the 7 for the size and the .2 for the exhaust housing. Like the others it is again the higher the numbers the bigger is the turbo

[@PalmBeachDyno]

Didn't forget it. There are a long list of things like this. We covered the turbos we use on the cars we tune.

[@MrLightning54]

I'd like to see a dyno comparison between a Journal bearing turbo, and ball bearing turbo on a Coyote of the same size / brand, and maybe a way to compare the lag between the 2 as well. Good video!

[@lockedinstreetracing6005]

I run twin precision promod 85s all I’ve ever run was forced inductions or precisions. I always thought it was funny that they all use different names and measurements.

[@MadsWorld34]

maybe you can give me a answer. i have a 2000 f150 4x4 4.6 engine i'm not looking to run 1/4 mile or anything like that. but you can out pull my truck with a good riding mower. i gutted the cats and resonators replace the muffler. fooled the 02 sensors. i gained a lot of power bottom end and gained 5 mpg.oh and i went electric fans but anything over 65 loaded with my boat the old truck is still hurting. the smallest hill and it falls on its face. what would be a good little turbo to help with higher end power. i was told i could put one right behind the Y pipe but i don't know. i have had this truck since it was new. don't burn oil runs great but like i said no power at cruising speed. and its 100% stock.

[@sumfoo1]

glen johnson I mean technically if you leave the rest of the motor stock something like a gt3076 would work but I would go for a t4 flange turbo at the smallest because after you turbo it, you are going to want more. So, that being said something like a gtx4088 or a small borg Warner sx300 series

[@MadsWorld34]

@@sumfoo1 thanks i'm going to look into them right now and i'm looking at your web site first

[@gtkid7932]

Do you know anything about the armegeddon gtx3582r kit on a 15 up gt? Power, size etc?

[@PalmBeachDyno]

We used that setup to be the first 6R80 in the 7s. But that car is now switching to the Hellion Sleeper setup

[@gtkid7932]

@@PalmBeachDyno so what is that actual size of those turbos? Someone said they were 67's but not from what i see. Why the switch? Any idea stock motor e85 with all supporting mods that would be close too?

[@PalmBeachDyno]

@@gtkid7932 Much less piping. The Armageddon kit performed well but not a great choice for a car that gets run a lot. IT's a VERY tight fit. We had some bolts come loose and there is no way to get back at them without taking a ton of stuff off. The GTX3582r is a 66mm inducer

[@mrt2this607]

So Anyone here have good experiences with turbonetics, the co. & their turbochargers? Having bought one early in project planning, later research hasn't given me much hope for quality build. After learning some more then calling to speak with company reps for more info was even less assuring. Multiple calls, same result -rude until you might buy another, customer support is non-existent. The model in question is a 350GTK, to be used on a gen2 3sgte. But looking for genral experience with them/their products. Anyone with input on this is appreciated

[@gtgodbear6320]

So a GTX3582 is actually 66-68mm turbo?

[@brussell639]

The bottom row is how much air in lbs/min your engine will produce, not the turbo.

[@PalmBeachDyno]

It's turbo flow. which is how much the engine will consume. The engine doesn't product any airflow, it consumes it.

[@brussell639]

@@PalmBeachDyno an engine is an air pump. Of course it produces air flow... right out of the exhaust pipe. To read the compressor map, you have to determine how much air in lbs/min your engine will produce based on displacement, rpm, target boost pressure, and your horsepower goal. And there's a few more complicated formulas you have to work thru, but that's what you're plotting on the bottom row.

[@clintwalter7659]

If we cram more air into it and much fuel it should run a lot better

[@HalferLandPerformance]

Till this day Garrett confuses me. I understand everyone else but them

[@Thr33.Sid3z]

Garrett & Precision are the easiest to measure/read. Garrett has been around for so long that it's just easy to know what the turbo is capable of just by the frame size I'll use a GTX3076R for example. • *GT* simply stands for “Garrett Turbo” & the *X* is the newest model w/ the improved Compressor wheel design. • *30* refers to the “frame size” of the turbo. This is based on the turbine wheel inducer (the inducer being the top of the blade). • *76* refers to the Compressor Exducer wheel size in millimeters. • *R* indicates that the turbo uses ball-bearings, rather than journal bearings. • *S* is rarely found on Garrett turbos, but it basically means the turbo has been slightly modified for a special application. The GTX3584RS has a brand new Turbine Wheel design that flows exhaust gasses at a higher, more efficient rate.

[@blkbird98ta]

Its some confusing shit. I hate when people talk turbo specs cause that t66 ko4 dont mean shit apparently . Thanks for trying to explain . Its all non sense if you ask me

[@bryanst.martin7134]

@3:23 PT shows they use a 66mm turbine. Makes One question your statements. It would appear that you are proficient if you are making your living from it. But you jeopardize your reputation with statements like "PT doesn't include much data". When your own data proves otherwise. Still appreciate your post.

[@brussell639]

Compared to the other manufacturers, precision puts the least amount of info on their website. You have to call them just to see a compressor map.

[@tommcqueen2840]

Confused customers are much easier to BS. That's the reason every turbo manufacturer does it differently.

that irritated the sh*t outta me. too much time in a machine shop will make things like that hurt your brain. great info on what the main focus was. not sh*tting on his knowledge, the info was spot on what i was looking for. after all he was illustrating how to "quickly guess" a size...but at least turn em over to the correct side for the task and get the most accurate guess possible.
