I have an Aerocharger 53 non intercooled on my F7 with 800cc Big Bore that i made myself, and Aerocharger says the maximum boost you can push the 53 SERIES TURBO to on an 800cc is 7psi SAFELY, anymore and you may damage the turbo itself since it cannot push that much air.
I do not know what you will need to make 200hp, at lower elevations you could probably get 200hp i'm assuming, but not up there.
I am going to run my sled starting at 38psi fuel pressure and go from there.
