Not much has been released yet, the largest should flow almost 100 lbs/minute which is great. Since these won't use the 11 blade billet wheel, they should be loud like the standard BW units, which is about all I care about.You might want to check out the new offerings that BW has developed for 2015. I have read that there are 7 new airwerks turbos that should be available sometime in 2015. I am hoping they offer a 300 series that used the 65mm turbine wheel. Does anyone have any specifics? I cannot find much beyond the link to engine basics above. The 66 and 69 are a little big for my project.
I got a February release, someone else said April, with a price range in the 1100~ range.
