Wondering what you guys are running your mark1 focus rs lumps? I need to put on a new actuator but wondering what a nice safe boost level might be for mine..........standard engine internals and standard turbo.

Running a k+n and dreamscience though, 222bhp at the wheels with a weak actuator


Any suggestions??

cheers

 

22psi with forge actuator running direct before i went hybrid

 

Same here peak 22psi stable at 19 above 4000rpm with the forge item.

 

cool, thanks guys. Gives me some figures to keep to

 

Just mentioning the boost is with a Ford motorsport manifold not sure if the normal mani will take it.
