Evo 9 + CBRD BBK Full turbo upgrade on 91oct and E85
Interesting.... what sort of airflow differences are you seeing in these two turbos at similar boost levels? I'm wondering if this BBK Full flows more than the 49-50lb range? Both turbos are on my radar and I feel like I'm splitting hairs.
i think he has plots....its hard to test the exact ratios, lbs/min, etc without a containment test cell...
we rate ours at 48(ish) lbs min

cb
Well if it's making 430whp on GST's dyno than that's already breaking 48lbs/min almost certainly! Seems more like 55 lbs/min if you ask me! 
I'm on the hair-splitting wagon as well....

The more BBK threads I read the more I have to shake my head in amazement on what the BBK Full is capable of doing. I have all of the usual "go fast" parts but I plan on upgrading to the Kelford 272s, E85, and ETS FMIC to liven things up once I return from Iraq.
