"Once you get up there" ???? At only 19-20psi I was seeing 2lb/min more flow than the 16g at 22psi. with warmer ambient temps, same baro. Raising the boost would just push the 16g close to the limit. The holset has far more map. IF the spread is the same at 45psi who cares??? its still a huge difference. We all know the spread would be greater because the compressor responds to higher boost levels. Anyone who can read a compressor map can see that.
Not a bolton gt30r can show more power at the same boost. You didn't read that anywhere. . . from a credible source. Not with the same flow modificatins (same upgrade manifold, same exhaust manifold, same bore/stroke).
Most I've seen a bolton gt30r turbo do is 131mph trap with 3300lbs (brianawd). And he was running 33psi, with an fp exhaust manifold (which is proven to give higher trap speeds) and an extrude honed intake manifold, with I beleive fp2s (bigger than hks 272s. While at 28psi with a full weight 1g (3100lbs) has done 126mph with a stock 2g manifold and no extrude honed intake and the les topend happy hks272s by Mike1992. Brian was also running e85 with the tune dialed in for it. MUCH more timing. AND he was running MUCH more compression. . .
You will need more than what a bolton gt30r turbine housing can give for such high airflow. It's just what has to be done. What you do with that airflow comes down to your fuel/tune and CR/pumping-loss/etc. The bolton has net such a number before; it's been posted in these threads within the past 6months I think. You'll have to look back to see the actual logs. But they are infact already posted. I don't remember the boost. But no it was not outrageous.
Regardless, the bolton hx35 nets much better airflow at whatever psi vs. the e3 16g which you are coming from of you so choose to upgrade. If you go full garrett gt30r, you sure as hell better gain more airflow per psi vs. a bolton hx35. You will be paying out the ass for the hotside.
I see. I just through gt30r as an example, I would never buy it though .
Anyways I see what you mean, here is a log of a 2g fp3052 running 11s at 27psi:

For those who do not have v2 to view, it is running around 46-47lbs/min at 23-25psi, just showing it is a more than hx35 in BEP housing with a 121.8mph trap. Only saying this because I hear so much on how hx35 better than these turbos.
Also my log of 40lbs/min at 25psi, just did this pull once I filled up at the station:

I could still push turbo a bit more, but clutch will not hold.
Either way I plan on getting hx35, just not sure if I should get it in T3 BEP or mitsu housing, which is why I would like to know differences in both, since I have not found too much on T3 BEP housing.
