eheh alvin24, u're right..I'm driving a 6a12TT perdana. Half cut from Galant GT Sport (not eterna saloon).Guess what, Dyno'd for 200ps on wheel at N1 with standard S4 piping (1.8"),stock air filter,hks hyper muffler (which I dont think add HP,dunno for sure..I installed it for sound and look only.),standard S4 bullet and the only performance part is safc2 that I installed before dyno.Unless N1 racing's dyno is not correct then I cant say anything la..boost 0.7 and galant gt sport's 6a12tt spec is 240ps on flywheel. For me, my turbo just to boost here and there, not for full time racing. Simply say, it just for driving fun!
btw, when dynoed that day, my boost drop from 0.7 to 0.3 when reaching 6k rpm.Turn out my ssqv valve already koyak.Now after fixed it I didnt do another dyno season yet. Maybe I will after change air filter & proper piping but I dont think I'll do it coz I love my FC now,better than my S4.rm30 for 180-200km. Not rly high if you ask me for 2L 1.3tan car.Maintainance wise? rm1.2k for every 75000km which might take 2 - 3 years and rm60 every month for lub. oil. Seems ok to me, and for nearly 6 month I didnt face any problem with engine. Where got high maintance for V6? as I know, 6A10 can use spare part from perdana which isnt cost a bomb.V6 sparkplug also last for 100,000km. Maybe you're right about the 6a10 engine too heavy for wira but if you not wacking corner kaw-kaw it doesnt matter right?
