I haven't put pump gas in my Evo in the last five years.

Which size turbine wheel was your green, 65mm or 67mm?

Very impressive M! Congrats on the new turbo! 33 psi @ 3800 (on a 2.0 in 3rd) + 540hp = Killer Combo!

65 mm.

What's opinion of the 3b vs. the bbk full?

would be interesting to see this one compared side by side with a BB red or even a JB red with the oem hotside and not the SS one

thanks for sharing this data. mad respect for blouch and CBRD on this snail. when a turbo clearly does everything better than an already very good FP turbo you get my attention. I am drooling at these results.

I love my 3B. I need some cams to wake it up.

Awesome results!

are there any differences in porting to the hotside between the 3b & hta grn??

Was your green journal bearing or ball bearing?

I figured you had a trick up your sleeve. LOL;)

The HTA Green came fully port-matched to the hotside inlet and outlet gaskets while the 3B was more of a polish job than a port job. So I bought a die grinder, some burrs, and port-matched the 3B hotside inlet and outlet to their corresponding gaskets. And of course I blended the larger openings to the passages like on the Green. I also did a bit of deep port work on the "smaller" volute. I doubt the latter made much difference, but I wanted to do it.

Journal. English showed there was no difference in power between the JB and BB Green.

No difference in power but response is better on the ball bearing units. Obviously you know this which is why you purchased the DBB bbk. The new green with the better housing and larger turbine wheel is a significant upgrade as well. I would say that you have an improvement for sure from what you had. I would like to see a new DBB green with 67 turbine and SS housing compared to the BBK 3B.

In another thread related to this same turbo, someone mentioned that the BBK-3B has gone through some improvements and that as a result the newest versions spool quicker than the earlier 3B's. Does anyone know what changes were made by Blouch to improve spoolup on the latest 3B's?

Maybe I am wrong, but I imagine that any significant improvement in spool would most likely be a result of further improvements to the aero design of the compressor and/or turbine wheels.

So, if the 3B has received upgrades does anyone know what exactly has been changed on these turbos?

fp said new housing spools 200rpm slower. and from what I can tell from results posted of roberts car they were comparing 93 octane TS spool results to E56 open scroll results with the HTA green. my guess is the new housing spools 400rpm slower. I dont need to see this comparison you will never see. the 3B is killing it. if you havent noticed CBRD turbos are never compared back to back to anyone elses turbo evo 8 or evo x.
