i already seen all those links. majority of them was posted this week. i spent about 90% of time on nasioc.

07 sti turbo is a vf43, compared to an 04-06 sti stock turbo it has a bigger wastegate. the 04-06 stock turbo is a vf39. they both flow the same which is about 450cfm. 20g flows way more than that and dont hit 400awhp unless it has meth.

the vf39 highest hp record is 361awhp (i think or 351, cant remeber). but that was on a dyno jet. you put that same car on a mustang dyno and it would barely break 300.

the fastest sti on stock turbo now (running 11.7 on a 06) didnt even break 340
11.7 @ 113mph VF39 06 STI - Timeslip and Video Inside! - Proven Power Bragging - NASIOC

dont get me wrong, it'll hit 400awtq all day.
