I'm not sure how small the vf39 was but the 09 and 08 WRX/STI get about 38 lbs/min turbos in the vf52 and vf48.

I think we're not communicating well. It seemed like you were talking about the minimum rpm required for the turbo to reach full boost, which you are correct in that the FMIC does not really change that. I was referring to the time it takes for the piping and core to refill after for example, you let off the gas and get back on it again. There was absolutely a noticeable difference between FMIC and TMIC in this regard. It's just physics. Before any pressurized air reaches the motor, it has to pressurize the core and piping. I know I'm preaching to the choir here, but I wanted to make sure we're discussing the same thing.
The VF39 was the same as the VF48, with the outlet of the compressor side having a slightly different shape. |
