get it on a RR or summit you cant say "it can/will run X Y Z amount" yu jus set it up to what suits the engine, be it 12 or 18 psi,
i know what you mean by this as i have difficulty trying to explain this to my m8s at the end of the day all engines are different, what works well in one engine wont even graft on another.
All i normally get off them is more boost = more power .
it seems using calibra pistons 14psi is about max form what i've seen on this site over the last year or two
well this is realistically what i've going to aim for for now with the std ke-management maybe less boost if the injectors cant/wont keep up.
out of curiosity i was reading a feature on an 2.1 zvh in an old mag i've seen the car on here before its the one that takes on the evo and wins ("its-evo-time!!!!!").
anyway he apparently has bigger modified injectors??? does anyone have any ideas as to where these came from or how to modify the std ones in to bigger ones???
