I'm new to the FC turbos cause I'm a first gen guy, but I'm thinking about a S5 Turbo setup on my FB. I found a lot from searching, but still have a few questions. (My goal is 250-280RWHP). Are there any common mods that can be done do the S5 turbo or manifold without spending to much money? I know about wastegate porting to reduce boost creep, but are their any other things that alot of ppl do to their s5 turbos/manifolds? I read somewhere that the S5 has twin wastegates, is this correct? On FCs, the wastegate is mechanical, and controlled by the ECU using a vacuum line from the intake manifold to read boost pressure, correct? Since I am using a carb, and have no ECU, I need to buy an electronic boost controller? The engine is going to use S5 NA rotors. I'm unsure of what boost level would be safe and what would be required to achieve my HP goal. I've heard varying numbers anywhere from 6psi to 12. The motor is going to be streetported - approximately what boost level would be required to throw down 250-280 at the wheels and is this a safe boost level for NA rotors? TIA
