Have just seen the sti9 zerosport demo at David Hendry cars. Quoting a bhp output of c 350bhp which seems high. Going for a test drive end of the week. Has anyone any knowledge of the car / what to expect over a standard STI 9

Currently have an EVO 8 Fq330 - so comparisons could be interesting.
P1 for 2 years and STI v5 as well, but been away from Subaru for 18 months.
