I have the Jackson Racing C38 kit which uses a Rotrex centrifugal supercharger. For the FA20 platform I recommend getting a centrifugal if you want a reliable way to boost that won't kill the engine so fast. Boosting the FA20 is not ideal on stock internals once you reach 350 hp. It's more expensive per HP, though. Turbo is still the cheaper route to go and can get you more power if you want to. Superchargers only get more power if you get a smaller pulley. If you want more linear and constant power, supercharger is a great way to go. You can get a twin scroll which is the one that whines when you drive it. It creates more low end torque which can spin rods super easily on this engine if you're not careful. Centrifugals build boost like a turbo so majority of your power and torque is on the higher end which these engines do better with. If I wanted to build my engine to 500-600 hp with a built block I could do that with this supercharger though. It's just personal preference at this point.
What supercharger do you have and what would you recommend?
