Using the older style bearing package instead of properly copying the G-series is definitely a big cost saving measure, but also a big quality differentiator. That said, the Pulsar turbos seem to last pretty well even with lots of abuse. That center housing definitely got mighty hot. My suspicion is this turbo experienced oil starvation, which is of course what kills most turbos along with foreign object damage. I doubt the issue was balance, though it could have been a contributing factor. I'd suspect debris reducing oil flow first though, personally. Fun teardown. Can definitely be rebuilt!
@ScubaMadeАй бұрын
Most the turbos I’ve seen with oil starvation have cracked the rear cage closest to the exhaust wheel and the most heat, that turbo didn’t have any signs of oil starvation but my thoughts are a slight balance or vibration of the compressor wheel and/or the fact no blow of valve was used which I forgot to mention, the turbo was definitely good as it was heavily used for over 2 years I believe! Definitely still a good turbo!
@802GarageАй бұрын
@@ScubaMade True, the cage being in tact means it definitely could have been worse. I was thinking small debris causing a partial blockage, so the center section just wasn't getting enough oil as opposed to none at all. Imbalance is possible of course, but it's funny I was talking to a friend right before seeing this video about how in failure analysis videos it almost never seems to come down to balance. No BOV will contribute to a shorter life, but so many people don't run one on high HP cars and the turbos live a long time. Definitely hard to say in this case! Thanks for the reply.
@ScubaMadeАй бұрын
No problem, thank you too! I’ve had a few good chats with the balancer and that helps me come up with some options. Even what he told me after balancing still makes me think it could have had something to do with balancing, but I guess we’ve got no actual way to prove it so it’s just speculation.

No Bov would have killed the bearings. They dont last forever anyway, but in a drift car thats driven about as hard as it could be, im surprised it wasnt any worse. (I dont run a BOV either, it just makes the turbo more of a wear & tear item).

Yeah I forgot to mention that in the video, haha whoops, and I don’t have a BOV on my Silvia anymore but I have one on my BMW! And Hayden definitely drives mega hard and a lot too so luckily it wasn’t worse for him!

@@ScubaMade yeah tons of guys harp on about running a BOV. Someone once made a good analogy & that was that if your turbo lasts 5 years with a BOV. With no BOV it might last 4 years.

@@ScubaMade My issue is that a Garrett G-Series costs far more than even a Borg Warner EFR, which is arguably the best consumer turbo on the market. I think they have the margins jacked up pretty sky high, personally. Not saying they are bad turbos at all, just that you are certainly paying a premium for the name. The G-Series is at least a huge step up from everything Garrett made before. Pulsar does a pretty convincing copy.
@802GarageАй бұрын
TBH no way to say what materials are better or worse without actually testing them. If you mean that the bearing package is inferior though, absolutely. The G-Series has a much beefier bearing package than the prior Garrett designs, so skimping there will definitely shorten the life of these turbos under heavy use. Primary killer of turbos is oiling issues. So even a small issue will be exacerbated by the older style bearings. That said, you are saving like $2,000 on average probably!

I’m still waiting for it to be balanced, it’s taking over 3 months, I should call them again soon! I just like to rebuild it myself so I know what it’s like inside and balanced properly!

Can be rebuilt quite cheap overall. Bearing package is the most expensive part. No reason not to rebuild it if the housings are good.

So are they made good or not? Do you think that’s why it failed, poorly balanced ❓
@ScubaMade10 ай бұрын
I haven’t ever used one myself but many people do and they seem to work well, just not as good as Garrett, but that’s indicative of the price, there’s a huge difference in price! And as for balancing, I have no way of knowing for sure, it’s just a guess that it’s not as well balanced as a Garrett but I also think compressor surge from not running a blow off valve could have contributed to the front bearing failing in this case!

@@ScubaMade I honestly can’t see why people don’t run blow off Valves out of spite? They seem to get a sense of pride from it??? If you understand how the system works & a throttle body shuts & there’s no where for that air to go, why chance that? And people wonder why clamps loosen over time & they always get boost leaks…😂 I run twin TurboSmart bov’s with 60mm trumpets & even when I only get on my car and make half the boost it’s set on they are loud! But the real reason I was curious about the turbo is I here a lot of hood things & there’s stories of all the high end turbos failing too. I’m putting a top mount big single on my car & was going with precision. But I might go Pulsar & save myself a grand if they’re that good. I mean if the materials of the turbo are good, bearings & design is all good, it doesn’t matter what name is on the side of it! Sorry for the book ✌🏻🏁

Ohh I have a BOV on my BMW but now I don’t have one fitted on my Silvia, but since the Silvia’s rarely even started I’m not so worried about it, but the BMW’s still driven often and on stock turbos so I think it’s good to have! Hayden mentioned to me that this turbo made over 700hp and got driven very hard at multiple events for over 2 years so I’d still say it’s a pretty good turbo for the price! No worries bro!

@@murk1352 I can explain why I personally don't bother with a BOV on my 2JZ: Because there is zero difference whatsoever in turbo shaft speed during a gear change or throttle-lift with the BOV vs. without. I never would have believed this prior to seeing HPA's video about it - but after fitting my own turbo speed sensor, I tested it for myself. Same results. There are several episodes of Engine Masters where Freiburger controls the boost pressure with a centrifugal blower by putting holes (leaks) in the charge pipes. It's VERY surprising how big that hole can be and still not drop boost pressure hardly at all. It comes down to the big compressor wheel simply moving a ton of air. My point is, that a typical 40-50mm BOV is probably not adequate to actually vent all the flow created by a big compressor wheel spinning 75k rpm or more - so the charge air must back-track through the compressor housing anyway - both with and without that BOV. It's the only rationale I can think of that explains why turbo shaft speed in unaffected by the presence of the BOV. Additionally and anecdotally - my 2JZ makes the same "pssssshhhhhhttt" when I lift off the throttle whether the BOV is installed or not. I have noted, however, that once in a great while I'll get a touch of part-throttle compressor surge I never had before deleting the BOV. Not trying to convince the world (or you) there's no need for a BOV. However, what seemed perfectly intuitive and logical to me before - was clearly wrong. It's easy to imagine that "column of air" flowing toward the throttle, slamming into it, and needing to be vented off to prevent back-flowing out the compressor - but there's simply a lot more to the physics of what's actually going on.

@@GroovesAndLands Wow that’s crazy! When the throttle body closes there isn’t really that much air from throttle body to impeller regardless of how long all your charge air with intercooler is! I have twin bov’s with 60mm trumpets on them & when I let off my N54 (3.0 litre straight 6) it’s loud and you can hear it. I have a video I wish I could post it with this message. It definitely moves out some serious air. I also have Zero boost leaks. I have all turbo clamps on all pressure 3” pipes & every coupler is tightened down. I definitely think they are a most on anything making 5-6 hundred H.P. & up. I’ll be posting some videos of some cool shit! I’m ordering a 6466 top Speedtech top mount kit for my car within the next few weeks. Hopefully I’ll have some videos of my car & everything I’ve done to it over the yrs. ✌🏻🏁

Awesome I was curious what they looked like inside. The bearing retainer pin might be that way to circumvent a patent. The end steel oring got gouged out, probably a poor material choice an there's no thrush load axially.

Actually I might have read that wrong, If you’re just talking about the inlet flange of the turbo and the outlet positions, they are very likely to be the same I’d think! But unfortunately I only got the CHRA of this turbo, so I didn’t get to see the housings. But things like V bands and T3 or T4 flanges are probably things to look out for!
