CBRD Speedfactory & Ball Bearings
Sorry guys major delays with my build but, my motor should ship to Australia come the next few weeks and in a few months when the build is together (may take a little longer due to a possible switch to a dog box) I'll have some figures.
I think some of you have seen the pictures of the motor but it's full race and set up to be able to run up to 40 psi on the track , I'm close to sea level so should have some different figures.
If no dogbox it will be running the sheptrans 6 speed.

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.

Here's a bumper-cam video of my car on the autocross course yesterday... my codriver kicking @ss and scoring the 1,000-point top run of the day. you can hear how responsive this CBRD BBK-B turbo is at lower RPM, but still has plenty of top end as well:

That was a pretty awesome autoX course, higher speeds than most courses I have been on...nice!
At Nationals held at Lincoln Airpark (Lincoln, NE), the courses will be approximately twice as long, on a WAY bigger lot, so less tight corners; and the surface is concrete as opposed to sealed asphalt, which allows for higher grip >>> faster cornering speeds.
Oh, and Lincoln's much closer to sea level (just under 1,200 feet) than Colorado, so my car will have substantially more TQ/HP than here.
That will be fun and fast.
Sorry for the noob question, but i forgot the answer to this question. I have the OG BBK Full. How much boost can i run if I track it hard on a road course on E85 + Built 2.0L + All support mods.
Right now im at 28.5 tapering to 26psi at redline. Is 30psi down to 27psi asking too much?

Again, remember that I'm at over 5,000 feet of altitude, so there's significantly less oxygen up here, and we're really trying to cram as much air into the motor as possible to compensate. And the faster you spin a turbo on a regular basis, the shorter its lifespan, all other factors being the same.

if you want to run a BBK JB much over 28psi all the time- id do a ball bearing conversion-
also- remember if you have any boost leaks- 28psi could effectively be 35+ psi the turbo is seeing!

ah okie dokie. I'll leave it alone and be happy with the power. Stupid urge for more power, when will you go away. 
If I do go Ball bearing. I'll most likely sell the BBK Full, the get a used evo 9 turbo and send that in for BBK-C. From what I have been told, it doesnt matter which turbo you send in, the price for conversion is the same. It would be a waste to send the BBK Full in.
Maybe im confusing something and referring to BBK-B BB and BBK-C BB. If i did, my apologies in advance.
So sending BBK Full JB for BB upgrade is how much? For the record.

I keep looking in the Dyno results subforum, but no luck. I never see any sign of C's.
What's the difference in spool between the B's and C's? Heavily leaning towards a BB-B but if the C's make more power and don't spool much worse I may go up a level. Not sure if the C would be too much for a DD though
