[@ShinMufasa]

Precision Turbo & Engine very nice

[@ap1s2k78]

Precision Turbo & Engine what creates the pressure for oil going into turbo? Where do you run the inlet hose from?

[@dragsta1988]

Hy guys i have a mishimoto catch can (big one) do you think i should remove it ? I have my 550hp setup on the sr20 since few years now without problems but since i installed mishimoto catch can there is some oil under the turbo it is not much leaking but it is there, i am not sure if it is a turbo line or on exhaust or inlet side of turbo how can i check it ?, what you think should i do Thx for your time and support Best regards from austria Dragan

[@ShinMufasa]

Dragan Babic as stated, sounds like a mount or possible part failure. Catch cans I have never heard cause turbos to leak. Is it vented or recirculated?

[@dragsta1988]

DarkMufasa thx

Almost 2 year ago I passed my driving test, I had no idea about up to fix anything on a car. I'm now currently sat with the whole front of my car off to get to my turbo to recondition it. Some very useful stuff here that I had no idea about, thanks for the great video. Time to remove the turbo and fix my car 😁

[@jeremycormier8559]

did it work :P

[@NexReloaded]

@@jeremycormier8559 Yes and no. I fixed the turbo itself but i had boost pressure issues and other problems. Moral of the story, be careful messing about with things you dont fully understand lol

[@RobertDIY]

Wow! Learned a couple of things, best info was about the crankcase breather system. Have seen some blow the oil dipstick out, didn't realize it would try to back pressure the oil drain.

[@dankydonkeh]

Hey Robert! Love your videos you're a big help in the volvo brick community, keep up the good buddy

[@mikeydeshon5637]

I dunno. I purchased a turbo from these guys. Bearing failure in 4.500 miles had a professional rebuild and it failed at 5.700 miles. Of course it was blamed on me. And I'm out 2k. So i thru it away and purchased a Borg Warner turbo. And have had zero issues.

[@mrmidnight32]

Mike Brailsford yea I’ve been hearing a lot of people post issues with them. I’ve got their water cooler 6266 and so far at 1,000 miles I seem to be fine so far.

[@vspinkboi]

Borg for the win

[@mikeydeshon5637]

Well I do have to admit. I was only using basic synthetic mobile 1. But sence then i switched to brad penn high zinc formula oils. After reading the information posted about oils to use. On forced performance web site. There is a chart pretty much saying we should be using very high zinc oils. My car is an old 91 Mitsubishi with a 4g63. So ALL emissions stuff including cats have been removed. With the BW. Turbo I'm using a 10/an drain and 4/an oil feed from the cylinder head. The combination works excellent. I don't understand why the precision turbo didn't make it. But it's to much money to take another chance.

[@pheonixfps9248]

I generally pull and bin atleast 1-2 pte turbos a month. Vs a garrett, bw, they're fragile. Good for power, but no durability. Chinese made, assembled in America. I refuse to use or recommend them.

[@stevenhorsefield2909]

If you get a turbo from a company that has industrial background like borg, garret ect. You won't have to worry there turbos get beat to death and keep on going. I've been a truck driver for 20 years and the turbos on them things sometimes go over a million miles without any problem.

I run a pte. divided 6262 bb with dual wastegates on my fd at about 423rwhp at 16 lbs. So far no problems and i have 10k on the turbo. Spools fast and makes good power. I do not run a turbo timer but i do run my car about a mile off boost before i turn it off. I do hear a lot of complaints but i have non at this time

[@williamgrant5608]

You just helped me decide on turbo or supercharger . Blower it is.

[@strider5119]

Turbo is way cheaper and easier. Most supercharger kits start at around 6k for a side mount, 10k for a top mount. Turboing your car is much cheaper, especially if you only want low boost.

[@strider5119]

simple solution is buy a turbo that comes with the correct fittings and lines as a kit, then no mistakes are made. Have some silicon joiners between your hard pipes to allow for flex and if there happens to be any pressure issue, the silicon joiner will jump off the hard pipe, well before a hard pipe or turbo is damaged.

[@andrewkahler9359]

@@strider5119 hahahaha if you think turbos are easier youre on one. If you can replace an intake manifold or change an alternator you can install a supercharger. Also, for low boost, superchargers do the job. High boost, you want a turbo or a centrifugal supercharger. Also roots type superchargers are inefficient but twin screws and centrifugals are much more efficient. Not as efficent as a turbo but still. SC kits are also not that expensive. I see a lot of SC kits between 3000 and 6000. Depends on application. Basically the same price as a QUALITY turbo kit. It boils down to this. Max drivability, easy install, decent power bump: Supercharge it Dont mind lag, want max power and uncompromised performance: turbo.

[@SydneyChromatic]

i wish i went that way instead of dealing with all this ridiculous heat coming from two turbos

[@dimmacommunication]

@@andrewkahler9359 Superchargers are king 😎

[@jimhiscott2918]

This video is 5 years old. For your precision ball bearing turbos use the TurboSmart OPR. It supplies a constant steady 40psi of oil pressure to your Turbo.

[@clutchkickpj693]

The vibrant hard clamps have plenty of flex to them so you can weld hard piping to the turbo with that clamp.

[@flyonbyya]

Learned a bunch ! In the past...i had a GN I modded with the typical precision turbo goodies, ( front mount IC, bigger turbo etc etc)...but since it was basically upgrades of stock stuff, I didn’t run into any of the considerations detailed here

[@DeathComposor]

My 6266 blew within 1000 miles, got it professionally rebuilt and it eventually suffered catastrophic failure in the same amount of time. I ponied up and bought a BB 6466 since I'm a glutton for punishment, lets hope it goes better this time around. And yes, i have checked the clocking of the turbo and ensured that my oil feed, drain, and orientation is correct.

[@mrbmd710]

Did it go better this time around?

[@accountsmaster9813]

Wow that first tip is a very helpful advice, never thought to idle first before shut off. Thanks 😎👍🏽

Thank you, I just got my first car with a turbo and not really familiar with them. Clear to understand and very helpful.

[@grimcomedy6356]

Let the car cool down after driving if you want it to last and let it warm up too

[@timothyscherer9163]

@@grimcomedy6356 depends on the car. IIRC If its got a ball bearing turbo you dont really need to let it cool down before shutoff like you should be doing on a journal bearing turbo car

[@soundseeker63]

Interesting info about the crank case pressure affecting oil flow. I was not aware of that before. But I'm guessing that is only a problem at higher boost levels? For a tuned daily driver running 1-2 bar of boost, baffled catch cans seem to do the job just fine from what I've seen

[@Apexracingbr]

Out of the box precision turbos smoke!

[@dawkrb]

Most newer turbocharged cars circulate coolant after the car is shut off-Like a built in turbo timer- My 2018 circulates coolant upon shutdown and my 1986 Porsche 944 turbo had it waay back when.

[@numinous4789]

Instead of idling, get a turbo timer if you have an oil-only CHRA. Or go to a piece that has oil and water in the CHRA. Many modern cars that come turbo'd from the factory have this, and will continue circulating coolant even after leaving the car in the parking lot.

[@JosephArata]

That information on oil restrictors is wrong. Factory journal small frame turbochargers from Holset and Borg Warner use oil restrictors to prevent the oil seals from being blown out on cold start.

[@wildimpo]

What is the proper boost for my drive 1.4 Holden Cruze manual boost control

[@forbiddenera]

Some cheaper turbo's too (im sure this all applies to their turbos) can need a restrictor especially on a high psi (oil psi) engine, he's right about it being a case by case basis and also there are different types of restrictors. I got a vibrant one that was like a pin hole, definitely not enough flow for my journal turbo but I originally had too much pressure. That restrictor actually got plugged and killed the turbo, its ebay replacement also came with a "restrictor" that goes in the oil inlet flange but is waaay larger than the pin hole one and just enough to lower the pressure enough (driving 90psi into this kinda turbo will leak past SEALS!) Again all case by case and what I've said here applies to cheaper turbo's we've worked with.

[@X5XST4RK1L3R]

Ball bearing turbos aren’t cheap you need reatrictors for ball bearing turbos.

[@gnarshread]

This has been very helpful! Thank you!

[@mcknightmetal]

How about mounting the turbo like exhaust side down and the air intake sign up

[@keithjurena9319]

Oil drain is fixed on the CHRA. It must be down. The labrynith seals only function properly with drain down AND free flow to crankcase. Ignore this and you will puke oil out the exhaust like you proposed or if compressor down, oil will flood the intake.

[@markbuilds4674]

Do i have to use an oil restrictor on a Hydrodynamic bearing PT76/75 turbo?

[@MrRotaryrockets]

just for your info a standard Mazda RX& FD 1993 and up use a standard 140psi oil pressure system which will over oil the standard oil system and blow oil out the exhaust. so we HAVE to run a Restrictor. and maybe you should be aware of the oil filter screen on the incoming oil supply line fitting which has a screen which can get crushed if a standard AN fitting is screwed into it..my Friend's TO4 e got supper hot and when removed had a blocked crushed screen stopping oil getting to the turbo so it burnt out the ceramic bearings..it lasted only a few days..we are NOT Happy..

[@shivaanishwarlall9433]

Installing a PTE 5862 Gen 2 on my Subaru STi, do I need an oil restrictor?

[@whoeverwhoever400]

I never knew about the hot oil inside the turbo. I usually just turn off the car right away, but I usually only drive between my home and work in the city speed at 30-40 mph, sometimes on the highway at 60, but usually only about 15-20 drive. It shouldn't hurt much, right?

[@gingersquatch9844]

I plan to have my exhaust side braced from my D16 block with a full flex joint and use fiber reinforced silicone couplers to "decouple" the chassis from the rest of the system. I hope to break the D-Series record of 812hp and push the limit to around 1,000hp to prove that the "single jingle" can "flex" with the rest!!!

[@kacienelson660]

Really like the tech talk .thanks

[@forbiddenera]

Garrett said it better than I can These bearings require enough oil pressure to keep the components separated by a hydrodynamic film. If the oil pressure is too low, the metal components will come in contact causing premature wear and ultimately failure. If the oil pressure is too high, leakage may occur from the turbocharger seals. With that as background, an oil restrictor is generally not needed for a journal-bearing turbocharger except for those applications with oil-pressure-induced seal leakage. Remember to address all other potential causes of leakage first (e.g., inadequate/improper oil drain out of the turbocharger, excessive crankcase pressure, turbocharger past its useful service life, etc.) and use a restrictor as a last resort. So not never on journal bearing but usually no. Again the "restrictor" that came with my eBay turbo isn't anywhere near as small as the "real" restrictor I got from vibrant (which was clearly made for bb turbos).. also, yes, the drain line is very important to be done right!

[@sxs4l245]

Also i may say or ad to this equation. Builders are always arguing pressure vs volume(oil) Just look at Cat vs Cummins (just an example don't get your panties all bunched in your V spot). And I have noticed way to many people are going for look vs function. Just go with more simpler there stupider...

Jokes aside thank you, in all seriousness, there was solid info here that wasn’t just a facsimile of every turbo video/article online. I do wish you’d gone into more depth/any depth at all RE: catch cans, just saying “not too much in the way of catch cans” doesn’t help me understand what the problem is at all, if you never advise them or what the deal is exactly there and how it relates to “a proper breather system etc. If you have any videos that go into detail on the topic I would greatly appreciate a link.

[@quillmaurer6563]

I'm working on installing a T3 off a junkyard Saab on a VW Bug. Turbo was designed for water cooling (was plumbed for that on the Saab) but my Bug is air-cooled, so no water cooling available. See a lot of other Bugs running similar turbos with the ports simply plugged, seems to do alright. Read literature from Garett saying that the water cooling is mainly needed for preventing oil coking after shutdown, not so much for while actually running, so the cooldown is the critical part. How much cool-down would be needed, would I need to idle for a while before shutting down, or would a few blocks of gentle driving on urban or neighborhood streets before arriving at my destination (as would be the case at most places you'd be arriving to if you're not hooning it in the neighborhood) be adequate to cool it before shutting it off?

[@rolandotillit2867]

Coking is basically evaporation of the lighter elements in the oil that rests in the bearing when you turn the car off. The hotter the oil the more severe the evaporation, what is left is tar, it is a hydrocarbon after all. When you boil the oil you evaporate the lighter stuff and leave the heavier stuff behind(coke). Great video that highlights this principle in different ways. Namely oil flow=cooling, and stagnant hot oil is bad.

[@Clem_Kadidlehopper]

I would like to hear your thoughts on compressor surge or brake surging turbochargers. I hear mixed responded on if it caused damage or not. I've been involved in turbos for a few years (ok over 2 decades) and have my own opinion on past experience. Thanks if you can answer.

[@rileyjohnson2663]

Billy Beane it doesnt cause damage because unlike what most people think it doesnt cause the turbo to spin the other way it just slows it down

[@abec666]

It stresses everything on the bearings side, vibrating the shaft and impellers in-out / up-down very fast. The best way to imagine it is trying to take a nail off a wall with the hand with quick movements. A rich moron in a nissan made a video proving he knows S__T about turbos... This is were all the BS about it non-damage on turbo came out...

[@Timbo0021]

What do you mean by "brake surging"?

[@brooksman10]

Abec777 Hondatech Maybe if you have a shit turbo, they're designed to be strong anyway. The only time it's really bad is when you're hearing it at WOT. Otherwise the only load on the turbo is the charged air, as there is no exhaust gas spinning the turbo when the throttle is closed.

I live in Kuwait, which is known for having a harsh desert climate. Summer temperatures are usually between 42-50 degrees Celsius, and dust storms are frequent. We use heat covers and add an air filter on the intake of the turbo charger. Beside those, Is there anything else that can be done in order for the turbo charger to function on a daily basis without failure & handle the harsh environmental conditions of the desert?

[@WifeBTR123]

Also make sure your oil level is full. Low oil absorbs heat faster and has a harder time dissipating it.

I've never once seen guys just drive around after running boost. I've seen thousands of turbo runs with guys at track or street running quarter mile runs and never seen someone come back to the pits and say I have to keep the car running. LMAO 🤣

[@mr34]

If my oil temps are low as for cruising around (as opposed to elevated for spirited driving), is it ok the shut the engine down straight away as the oil temp isn't going to come down with extended idling? I would imagine extended idling is good if oil temps if higher than normal ie; for track use.

[@precisionturbo]

It is always best to idle the car for awhile after driving spiritedly as both the turbocharger and oil will have elevated temperatures. If you were to drive the car down the street modestly, there would be no need to idle the car for an extended period before shutdown.

[@jesuspadilla3910]

[@RogerMiller-td5yc]

[@renderyours510]

Dan Aldred i assume he's referring to the oil feed locations?

[@Wischmaster]

No greater than 30° in either direction from center for oil returns. More vertical the better as the return section of the system is not pressurized and relies on gravity alone to return the oil to the pan.

[@lancemenke2728]
