the 39 flows more air imo but ill see when i get there. im hooking up the fmic and a pump the same week the turbo goes in. ill only be running stock boost until i get some management.
get your car running right and we'll compare silps in the spring.

At 14.7psi, the 16G already flows more than the stock engine can injest at 14.7psi. So anything more isn't going to do a whole lot. I think the 16G flows like 505CFM, and the engine can ingest 450 or so. The VF22 flows like 480CFM, and the VF22 is bigger than the VF39 IIRC.
I don't recall, exactly, the compressor maps. Brat4by4 mentioned them and showed me the maps.

the 39 uses the same compressor section as the 22 just its not titanium and a different wheel. it also has a smaller exhaust housing giving it midrange.
if the 16g flows better than the 39 i think they (fhi)would have used it in the newer cars instead of going to a vf series of turbos. imo
