Great result today on Kosta’s blobeye sti.
Still running std headers, std STi tmic (with a unique mod) and a VfF43 turbo we saw 405.9bhp on RCM’s rollers today.
Running a 20% methanol mix with vpower and previously running at 383bhp (again on rcm’s rollers) Kosta added an uprated actuator and a good aftermarket inlet hose and we saw it climb to 405.9bhp. Not a bad result and certainly the most I have seen on a VF43.
