I had a wastegate completely fall off of my Vargas turbos. The Vargas wastegate upgrade didn't seem to matter, I've seen a few of their upgraded wastegates fail. It could be that the dme is providing them with enough vacuum but the pressure could just be blowing past them.

[@paulsimpson8990]

I have the same leaf blower. I miss the roller bearing turbo from my xr6T…you could hear it spinning for a minute or two after you shut the car off. The plain bearing in the Vargas is shot, fill your new ones with moly grease before they’re toast too!

[@friguy4444]

It really seems like the Vargas turbos have bad bearings even though they also seem to spin fairly freely. but I've had a wheel bearing that spin very freely on the hub but when some real weight and speed was applied it would not spin very well at all. IMHO this is similar. Great test you made up LOL. It Worked!

[@ichoozjc]

Is 8 in/hg (inches of mercury) right for an n54? I know on my N55 PS2 I screwed up initially and set them around 9" and I was hitting like 21 psi. Set them to Pure's recommend 6" and BOOM...26psi. You have 8, but if your vacuum gauge is just a little off it could be your issue. Or 8 is just too much.

[@ZeroTo60Tube]

Put a new manifold on the car last week. Didnt make any difference.

[@kencooper8636]

The difference in wheel sizes between the Vargas Stage 2 and DAW Flow Max+ is unbelievable considering they are both upgrade hybrids. As you say Andrew, the Vargas turbos look to be in reasonable condition. As a couple of fellows have commented below, whether the wastegates aren't completely closing when they should, could be the issue. Certainly a mystery which will be solved when the DAWs are installed. If the boost issue is no longer present which we all hope will be the case than there is certainly an issue with the Vargas turbos.

[@DERxTECHNIKER]

The Wastegate must be shut at -5.9inhg. I had exactly the same issue with my turbos, so I readjusted them and since then they just rip. You can look this up in TIS, BMW says -200mbar which equals to -5.9inhg.

[@ichoozjc]

I just posted this! Yeah had same problem on my PS2 turbo. Had them at 9" and only hit 21psi. Contacted pure and they said 6". Was hitting 26psi after, in the summer. Cold air I'm now hitting 22-23 but even higher load.

[@chrisbelcher5320]

Just from the picture, your using an oem outlet pipe with upgraded turbos? Your front turbo is going to see back pressure cause of that pipe design. I’d look into a better flowing front section on that outlet pipe

[@ZeroTo60Tube]

That is correct. Unfortunately until recently there were no options for RHD upgraded outlets which is why this car would have never had them. We have some made up for the flow max's tho

[@RobOnMotors]

[@cornfedboost]

Those Vargas turbos seem worn out could have been the issue 🤷 but oh my those new turbos look very pretty indeed 😍

[@ZeroTo60Tube]

Yeah, who really knows. The part number on the turbos implies they are 5-6 years old. They could have had the CHRAs replaced at some point with the wrong ones.

[@igotaction]

Make sure you are inspecting you exhaust valves while the turbos are off, check if valve stem seals are leaking oil. When I watched the video it looks like #3 might be leaking a tiny bit.

[@ZeroTo60Tube]

Great point! Will double check them.

[@DefaultLoginDetaiIs]

Do both the Vargas turbos have the same issue with sluggish turbines?

[@ZeroTo60Tube]

Both exactly the same. I am wondering if the CHRAs have been replaced with standard ones. And the wheels are too small for stage 2 housings.

Gotta get to the bottom of this! Voltage regulator and boost solenoid signals fuzzy? The fact that boost holds steady makes it unlikely to be electrical. Fricken’ aahhhhhh! Torque limiter? This is a fork in the road, I would really value some kind of diagnosis, but am also eager to move on to see the build continue. Just a guess, worn engine mount causing leak under load?

Stay healthy, stay safe, and thanks as always for sharing.

[@ZeroTo60Tube]

From all the testing we did back in march, everything electrical is spot on and when i had the guage on the wastegate line while driving the turbos were always getting -10 or better vacuum. So they gates should have been locked shut, but still no boost.

I recently found the HPFP Overdrive system by spool performance, it looks like that would allow you to produce enough fueling for the flow max turbos. And even tho it's expensive, that plus an upgraded fuel pump would be cheaper than port injection. Port injection just sounds to complicated to me so I'm wondering what alternatives there are out there. Also, fueling is confusing lol

[@ichoozjc]

What's the limit of the DI injectors though?

[@B0JACK]

@@ichoozjc i have no idea

[@ZeroTo60Tube]

I really dont like the overdriven HPFP options for the N54. Its not a new thing at all. Spool over drives a single pump. VTT used to overdrive a secondary pump. The VTT system in my opinion was much safer, but they still didn't last. Trying to run over 600whp though our index 12 injectors is just a time bomb. PI is the way in my eyes it makes the power and takes load of the di system.

[@maxamillioncorrea6002]

Its also important to note that the Overdrive kits add more stress to the timing chain, and there have been documented failures attributed to the Xtreme version.

[@Nico_335i_DCT]

Maybe too much friction in the bearing area. So there is more exhaust gasses needed to spin these wheels. That would explain the late boost kicking in at higher rpm's. ( ps my new injectors are great. But now my HPFP decided to slowly give up. Long cranking at cold start. I guess my welcome to the N54 club) Dutch regards, Nico.

[@ZeroTo60Tube]

Ohhh man, good times ahead for you im sure. Its comming.

[@milehighboost5521]

If you are going to throw those vtt turbos out you may as well disassemble the turbos along with the compressor wheels to find out what's specifically wrong. Hopefully you don't find out the oil feed line(s) is clogged or something as that could start seizing your new turbos. Only other reason i could see the turbine wheels not spinning freely is if the turbine fins are damaged causing the air to pass through/ clearances not tight enough. If you do disassemble them make sure to mark the nut, compressor wheel and shaft so you don't have to re balance them.

[@ZeroTo60Tube]

I will be taking them apart i think. I have a bit of a theory. These turbos are 5-7 years old right and not leaking a drop of oil. I wonder if the original vargas CHRAs got replaced at some point with the wrong size wheels for the housings. Maybe with a stock size CHRA. I did notice the comp wheels are cast, not billet. Would have thought all the upgrades comp wheels would be billet.

[@greenlungo3996]

I don't mean to be annoying, but there is a more "fair" way to test the turbos without the use of too much special equipment. Firstly, the bearings MUST be actively oil pumped in order to work correctly. Spinning them without oil flow is non-representative and destructive. In order to get the operational RPM, you could shoot a compressed air gun down the center port. You could then use a free sound editor like Audacity to frequency analyze the sound recording of each turbo's spool using the same amount of air charge. You would see several harmonic frequencies, but there would certainly be a loud one coming from the compressor. You also have to apply a ratio factor for the different blade count on the wheels in order to convert blade whips per second to rotations per minute. I'd very much like to see this test, as I have trouble understanding how it is possible that a larger turbo, featuring a much larger 9 blade turbine, and a heavier compressor wheel could exhibit less lag. I would think if all that power was going into bearing friction, the CHRA would explode with boiling oil on WOT pulls.

[@timmurrayy]

I’ve had a clients car with VTT Stage 2’s that did exactly the same thing. We boost leak tested it, no leak. Vacuum system was fine. Boost solenoids changed, no change. Pegged the WGDC at 100% and it was laggy and only held 16 psi peak and tapered to redline. They were smokey but they behaved exactly like these. Looked like a mechanical wastegate or rotating assembly issue (bearing drag?) from the logs and given what we’d eliminated. Only turbos I’ve seen ‘fail’ that way.

[@BTSyaya]

Inches of mercury lol that’s the measurement your looking for. Also wastegates should be closing at 6-7hg at most. 8hg is too high and that’s probably why they were fully closing until 4k rpm.

[@ZeroTo60Tube]

When i had the guage on the wastegate line while driving the turbos were always getting -10 or better vacuum. So they gates should have been locked shut, but still no boost.

[@HassanEido1]

Check ur blow off valve man If if has a Chinese bov, they come with very flimsy springs. The bov stays open for too long that it doesnt spool below 4k ,then boost pressure just keeps it cracked open all the way. Wont show up on a smoke test.. It could also be the oring on the bov.It's very tricky when a car doesn't make boost . It could be anything. On one car( not similar to this though) it would hit 24 psi quite quickly, but taper off sharply at 5500 rpm down to 6 psi..and wgdc would go to max .after having racked our brains checking everything from wastegates to blow off valves to installing a jb4 etc.Turned out to be inlets getting collapsed under high flow . It was running the stock intake with a drop in filter, a simple dci helped immediately,and it now holds boost to 6500, wgdc only at 75% . ive also tuned a vargas turbo on a 135 recently and they spool fine at around 3000 rpm and hold boost to redline..they are lazier to spool than the 17Ts,similar to 19T, but they make gobs of boost.
