Probably posted before but can't find, stock flow for 84-5 turbos is approx. 390 CFM, what about the stock 86-7 flow CFM? How about the next step up aftermarket turbo CFM? Thanks.
I can't find it at the moment, but thought I recall the stock turbo at 535 cfm. For comparison, the TA49 is 800 cfm, TE44 is 850, and TE60 is 900, per the Buick Power Pac book.
