It is his channel, so i assume yes.
But my bad. He blew his engine on DAW stage 2.. and now looks for stage 4 ..
Wait a minute....
So you're saying some company started selling hybrid turbos, swore up and down they had magic sauce in them, he doesn't go on forums, had resellers spamming his stuff everywhere, and his product is shit? Weren't there lots of people putting their names on the line acting like they knew something everyone else didn't know for ten years?
This has happened like 20 times, yet I bet next month there's going to be some new hybrid turbos for sale that are special somehow. I'm not surprised and it's pathetic watching people believe that, let alone propogate it.
If I didn't think those people are ignorant or mentally retarded, I'd call them crooks.

How in the world does any turbos blow up a motor lmao. the motor blew up cause we pushed 31 psi at 6300 rpm with 17.5 T snall turbos. That's it. If you had told me hey bro I told you that methanol system was bad but you didnt listen then it's one thing, but turbos had nothing to do with the motor. Pure stage 2 high flows did the same thing at the same boost recently for a guy I know on 31 psi it was a 335is blew the motor exact same way. Btw the motor went out after the pull and we found out I hurt the motor because transmition was slipping and recorded 7500 rpm 3 days prior when i was racing two GTRs. It just finished at the dyno. There is thousands of ebay cheap turbos but they are not blowing up the motor right? They just go out which is pain to swap. Just need bigger turbos and less boost

But Sir. Them Hillbillies say they are pushing 800whp with RFP custom tune on 91 octane DI only.
They must be good!
Btw this is what the car did the 3 days before the dyno. Turbos were effing amazing for so long I couldn't be more happier. This was 29 psi of boost VS FBO E85 GTR. The only decent run we had since the tranny was slipping because if custom tune. Not the tune but the shift points were changed. After that day we fixed it but the motor was not
I have no doubt that some of them perform and probably will even last. Its the fact that hybrids have the reputation for failing at an alarming rate. Even with some mistreatment, that absolutely shouldn't happen. People classify failures with a very narrow scope:
Confirmed Failures:
- There is evidence they broke for reasons solely due to the parts themselves
- Parts failed but we don't trust the report
- There could be outside influences which may impact the failure
- No proof the parts were at fault
- Authorized installer not used
- Didn't run an assortment of authorized supporting parts
- Turbos failed but owner would suffer financial penalties by mentioning it
Personally, I believe that trying to take a part and modify and run it at such a high level you're basically running a glass cannon. Breathing on them the wrong way when installing or balancing them leading to issues down the road shouldn't be acceptable. Way back when, it was estimated the power ceiling would be much lower, yet here we are. Perhaps they thought about that power ceiling in terms of long term reliability, not peak power performance. Continuing to move the performance needle leads to an increase in reliability issues, I'm not really sure how this is surprising.
I know exactly what you mean, we installed stage 2 daw turbos and have been super happy with them as well as couple other buddy's that have them. We were at 29 psi for a while and oh man I loved how they performed! No issues with them at all! We shouldn't have turned the boost to 30 psi at high rpms but it's ok we learned! Just need to lower the boost a bit or get bigger twins and keep it at 27 psi that way I can be 650 to 670 whp and be on the safe side
So do you know any one who has had to remove their turbos for one reason or another? How many?
so far any guys that installed them including me have not had any issues up to this point. I will take out my engine soon and see how the turbos hold up. Hopefully it didnt damage them. The turbos didnt make any rattle or noises, boosted very strong at 30 psi. Wdgc was high 60s and just touching 70 wdgc. Have logs of lots of pulls
So getting back to the title of the thread (there are already too many on stage2s and barneys over reliable or not brand bitching) Do we yet have any results from stage 4s that indicate they are genuinely able to make 850HP?
Like 9second/140mph+ 1/4 mile in a full weight 335i ect...
Are there any people left running them?

This was mine on 27-29 psi before retune. I am gutted a lot though. AGAINST 770 WHP ctsv that traps 137 mph and runs low 10s
This is the thing that baffles me so much with the N54. This kind of turbo pressure just screams inefficiency and short term reliability. Unfortunately I've had some issues getting to completed with the port/polish head for the Z4 so my TD04 twins and related upgrade parts are all on a shelf until that is cleared up. But my hope is to be at 600whp on emix and be just under 20psi. Possible? Not sure. But tons of boost just tells me the engine is not set up to make the power. And the N54 as designed, is not made to make this power reliably, IMHO.
Maybe more so with a big single, for sure. Seems much tougher with twins. Glad it is working for you, but I don't see 27+psi in my future - I think it is working the wrong end of the problem
Filippo
I know what you mean. But even 25 psi is going to be reliable. If mine were boosted high and had lots of abuse over 22 psi and then 29-30 psi for a while. 24 psi would last you a long long time
For the most part I agree with you, though I don't think PSI in itself is specifically the issue and moreso the psi in regards to the turbos being used. It is baffling to me too though that so many people on this platform would rather run the cheapest turbos they can find, then just overspin them and risk doing more serious and expensive damage in the future just to save a couple bucks at the time of purchase. The stock turbo frames/housings certainly should not be run at that high of a boost pressure, especially since it's been shown over and over again that it's going to drastically reduce the lifespan of the turbos due to heat, backpressure etc. It's undeniably going to be better to use almost anything else for the extra HP at that point if you need to push your turbo(s) to within an inch of their life. I think spinning turbos up to ~30+ psi is probably fine for most of the larger sized housing turbos that aren't "true hybrids", though that obviously still opens up another can of worms or two - but even 27psi is higher than I'd go for stock housing turbos if I was planning to use them for anything other than a glory run or dedicated strip car.
The roll race looks like it might show some signs of promise. Although, more definative will be a real drag strip , roll race event and or dragy data. Ive knocked over some quicker cars in roll races. Usually by virtue of gearing , reaction time and getting lucky. However, if its on a propper half mile even winning over the line you can see that in the terminal speed differences. The car with more power traps higher mph even if it loses due to above reasons.
As mentioned Boost is one dimension Setup/tune/supporting mods and so on. Which is why bigger dollar setups ,being more comprehensive are usually showing the goods.
My pure st2 , managed to do the 10.7 @131mph on 23psi (full weight and interior) 0 timing (2nd revsion tune). Others will be running higher boost and timing and trap lower mph. Everything needs to come together. Right now i have about 6deg on 24psi which woke it up alot more, still more headroom on E85.
But, back to the stg4s discussion. Keen to see if the casual roll race footage translates to something a little more concrete but, looks promising so far.

A guy not long ago had a nice 335is and his blew the same exact way as mine with Pure Turbos stage 2 High Flows at exact same boost as me. 31 psi. Both of our motors blew same way after did the whole pull and then after the pull 2 seconds later when they let off the gas they said bye bye
Pures, even fully optioned out stage 2s, are still stock turbo housings and 31psi is still higher than those should be run at too imo. It's not at all surprising to hear that engines have blown from that combination, especially stock engines. Torque is what kills our motors and those small turbos when run at high boost (especially if it's set up with aggressive spooling) produce high torque levels and do it very quickly, which is a good recipe for destroying an engine.
I just don't see the point in running either of those or similar sets at such high boost, even aside from the heat problem I mentioned earlier they just do not flow enough to run well at that level. You're looking at heavily diminishing returns at that boost level and the turbos struggle to maintain that boost level at the end of the RPM range anyway. I would not push any twins smaller than any of the true TD04 twins (Hydra HP800, MMP S3 or 1K, RB GF, VTT GC) at anything passed ~25-26psi in 99% of situations. Honestly pushing passed 30psi on anything isn't a great idea unless running a built engine, but at least a larger turbo(s) wouldn't be choking themselves and would still show appreciable gains from the extra boost.
Yes, your right, that's why I was thinking to get the stage 4 turbos that are true TD04 (46mm wheel and 52 mm compressor rear wheel) and keep it at 26, maybe just maybe 27 psi max, that way they spool longer then the stage 2, and will be a lot easier on motor and transmission, but hopefully make 650 to 670 wheel horsepower l be super happy. What you think?
The boost pressure isn't the killer of the motors here, stg2's on 30 psi aren't lifting the head, you can and most tuners do tune the spool. Once you are making the kind of power/torque even st2's are capable of , there are things like tune (too much torque), oiling , fuel and wear (tired engines) that are most likely to seal your motors fate . Throw in some randoms like crank collars as well . Built motors and all the supporting oil/fueling mods are how you sure this all up regardless of turbo options (single or twin of any size).
Pure st2's (probably most st2s) can be run at 30psi and they will make power nicely up to that point without huge heat if in the efficiency island . Pure turbos themselves even suggest they can live there and tuners can provide a tune that is plenty safe in terms of detonation (E85/race fuels), we have seen logs that look totally fine with reasonable IAT's etc. However , to have a chance the stock motor is going to need to have the tune tapered to deliver the torque /HP so that its coming in further up so rods don't give up. 24psi is enough power on E85 to destroy the motor if you aren't tapering in the delivery on the tune. Even then remember that the extra power is beating up the rod bearings alot more than stock levels. So it accelerates wear accordingly . How much life is left in the bearings on old high mile stock motors is a lottery.
Back to topic ....
VTT GC's I think are the only bigger twins I think we have seen with an 'almost' 140mph terminal (138mph and not sure if it had some weight reductions). stg4's in this case are claiming power that ought to see them firmly deep in 140's without weight reductions in a 335i
