You stopped reading. Again you're talking about turbochargers you are not willing to read enough about to know their sizes, flow capabilities, nor results. You're partial picture defends your choice. And that's great. Yet, the proof remains.
That was 33 psi with a full weight car. The 37psi was with a hx35 turbine wheel. The hx35 is a smaller frame size than the gt35r. The term hx35 is like the term t04b or t3. What boost would a 56trim compressor have to see to achieve a 600+whp trapspeed with the discopotato turbine wheel? The gt28rs spools as fast as the hx35.
The 'hype' is the spool speed vs. similar flowing turbine wheels. Or flow vs. turbine wheels of similar spool speed. Look at the hx
40 results again. Please find a turbo that can run less boost make more power and spool as fast. Look at the hx
35 results again. Please find a turbo that can run less boost make more power and spool as fast. Why compare a 600whp garrett turbine to a 500whp garret turbine? A 600whp garrett turbine can certainly reach said trapspeed at a lower peak boost. Why compare a 600whp garrett turbine to a 500whp Holset/BW/IHI/MHI turbine? Unless you don't even know and understand the flow of the frame sizes of the turbo brand in question. Yes, this isn't rocket science. The 'hype' is that I paid $350 for my h1c (older hx35) and bep housing and have a turbo that spools as fast as the 16g it replaces and flows more at less boost than my 16g. Airflow numbers much like a td06h 20g. Here's another
h1c user with logs. Using a 2g maf, Bolton turbine housing, stock manifolds, HKS272s, 2.0L at 22psi. Airflow is airflow, efficiency is efficiency, faster spool is faster spool.
There are turbine housing choices for the hx40 that will give just as much lag as the gt35r in the .63 a/r single scroll housing. If you're willing to accept that much lag to reach your goal, then you can see over 600whp trapspeeds with much lower boost than 33psi, respective of the housing choice. It's not rocket science, but not exactly like tetris either.
Oh well. This is what I get for mentioning an hx35/40 when ecoli asked about just the hx40.

Never mind his huge boost leak
. The most he could get was 26-27psi that day. This is the same guy who trapped 132mph at 33psi.
You missed the other
bolton hx40 that did 516whp on a dynojet. They read high, right? Video of
11.08@128mph fullweight car: "
Full weight, still had bumpers, power steering, heat". 128mph at fullweight as quite a bit more than 516whp. I know you know where this is, but for any who don't:
Stealth 316 HP from et and trap speed.
Please look back. I never said anyone trapped more than 132mph. Where are you getting this? There's only 5 guys out of 10 that have even been to the track. Only 2 hx40s. The rest are guys with the small hx35 turbine wheel.
Someone tried to argue trap speeds. When does 150+ mph with a 600lb lighter car disqualify a holset? . . . Preference does. That's fine. Performance hasn't. The HX40 has proven to deliver over 600whp through trapspeed/weight and dyno. No, it is not rocket science. Nor does my wallet mind the difference I paid for my hx40 in the shed versus a real turbo. Cost versus output is not rocket science either. Airflow is airflow, efficiency is efficiency. And faster spool speed is faster spool speed.
