CBRD Speedfactory & Ball Bearings
Red is quoted at 60#
BB BBK-C is quoted at 61-62#
Black is a 68# turbo
So....there you go.
Enjoyed an awesome convo with Chad during lunch while I ordered my Ported BBK-3B with a Perrin intake adapter pipe kit. It was like talking cars with one of my best buds from minute one, but I'm going to end up with a kick a$$ turbo upgrade afterward. 
I should have it installed, tuned, and on the dyno for results within 2-3 weeks after I get it, so I figure late Feb./early Mar. for a dyno results thread from me. Can't wait!!!

It doesn't make sense that given the same compressor side and the same turbine side you would see a 50WHP increase just from changing the bearings on a 16G based turbo.
Naw. It just doesn't sound right to me that going from JB to BB on the same BBK turbo is going to result in a 50WHP increase. Going from JB to BB or vice-versa is probably only going to affect turbo spool-up, rate of spool, and transient response.

which is how it works

Chad on 91 octane, is the BB BBK-B worth it, will it make enough power to make it worth it to move up from a JB FULL?
The JB Full has proven to be capable of 370-400 awhp on a well set up car using cali 91 octane, so if the BB BBK-B has the EXACT same same spool or faster than the JB FULL, would it really make that much more power since fuel is the limiting factor for me.

THey're both good turbos, just different approaches.
There are just so many B's and I am just not quite up to speed on the nomenclature yet. I am guessing that the 3B refers to a specific turbo in the CBRD lineup such as the CBRD BB BBK-B, for instance.
The BB BBK-B does sound good, if it spools as well as a JB BBK-Full(it isn't called a full anymore though is it?), but delivers 50 more WHP up top. It does sound like a win-win scenario. Thanks guys

IIRC, Bryan at GST felt that the BBK turbos were much more friendly on 91 pump gas than the FP turbos. From what I know, Robert at FP designs his turbos to handle high pressure ratios. Chad has a different philosophy.

FP turbos like higher PR in relationship to BBK's. With that said, @ 25psi, the HTA Green/BBK Full debate was always an toss up, but after 30psi FP was favored.
For 91, 24~27psi range seems average for most stock framed turbos. So, if bbk-b is it setup similar to the full (like less PR), will the bbk-b make more power than the full and still retain the full spool on 91?
You can go look up the dyno plots of BBK turbos from GST.

Wouldn't peeps running their Fulls, in let's say, Auto-X, and wanting a bit better spool and transient response, be well served by having their JB-Full upgraded to a BB-Full configuration.
Also, from what I have gathered on here, at least on the BBK-Full turbo, a surge ported compressor shroud would be required in order to maintain an optimal level of drivability. Is this correct? I do understand from Chad's comments that the added cost of the comp cover elevates the price of a BB-BBK-Full to a high level.
So, I am wondering now if a BB BBK-Full fully decked out with the anti-surge housing and etc. becomes prohibitively expensive. Chad will you PM me what a BB-BBK-Full configured with the surge ported shroud will cost me? On second thought, you might as well send me the prices of both the BB-BBK-B(3B), and a surge ported BB-BBK-Full. This way I can decide which way to go.
Would a BB-BBK-Full spool almost like a JB BBK-Lite? Is the BB BBK-Full probably going to require fitment of a stronger than stock WGA? If so, what are the options?
