CBRD Speedfactory & Ball Bearings
I don't have a graph to show you, but I recently dynoed my car with a CBRD BB BBK-B with the 3.5" antisurge cover on a Mustang dyno.
At a peak boost of 28.3 psi, I made 527 whp @ about 7000 rpm (HP line is pretty flat between 6300 and 7400), and 497 wtq @ about 4800 rpm (300 wtq by 4000).
My build is a 2.3L stroker, 10.5:1 C/R pistons on E85, but with a stock head... complications with my built/ported head forced me to run this mismatched combination right now.
There are other factors that make these figures not really relevant to most of you:
Sorry I don't have anything more helpful at this time.

There are other factors that make these figures not really relevant to most of you:
- I'm at over 5,000 feet of elevation, so even with corrected figures, the curves and peak numbers aren't really comparable to what this setup would do closer to sea level
- This tune was intentionally detuned to not exceed 530 whp, because that's the max I can show on a dyno sheet and still stay legal for NASA TTU Time Trials class, based on my vehicle weight, tire size/type, etc.
- I'm running the HKS/Kansai Service 4.11 final drive, which I believe changes how the dyno creates load against the wheels and therefore the engine during the pull
Sorry I don't have anything more helpful at this time.
