sometimes you can ad more boost but the engine not cunsume the air is what the blokes getting at

you can have 32psi and slow the car down i belive, stavros or chip will confirm if im talking shite im sure but thats how i understand it

psi is presure not flow, when you are increasing the presure but the head aint consuming your presure will still increase aswell as temps but the engine wont actually be getting much more air inside it

my engine was holding 27psi to the limiter but maxed out the greens and was running a little lean after 6300rpm in 4th and 5900rpm in 5th gear as it was consuming the air meaning that i the 27psi was alot more air than say 27psi on a head that aint flowing the air

sorry im shite at explaining things but if your injectors are flowing more fuel for a small amount of boost they the engines working better

big big boost engines dont mean better engines for more power/top speed

though i belive you will loose low down torque or something like that

infact ignore me and PM stavros as thats what he knows about
