My gut feeling is to fit a swirl pot between the tank and fuel rail for added protection for any tuned engine set-u, would this be wise..
i dunno anything about these cars so i'm speaking generally here,
power output has nothing to do with needing a swirl pot, thats purely down to if you suffer fuel surge when cornering, if you dont then you dont need one, although many cars even with manufactures built in pots can surge when the tank fuel level is low.
a swirl pot on its in the fuel line on its own wont help without an extra fuel pump. think of the swirl pot as a baby fuel tank, which is kept topped up by a low pressure pump that takes its fuel from the main tank, your main fuel pump should take its feed from the swirl pot, the returned fuel from the engine should go back into the swirl pot, and there should be a return from the top of the swirl pot to the main tank,
this design cannot suffer from fuel surge, as the swirl pot usually 1 litre capacity, is too small to allow the fuel to run away from the outlet to the pump, even if the low pressure pump in your main tank does get starved of fuel, together with surplace fuel returning from the engine it has enough fuel in it to keep the engine feed until the low pressure pump is supplying fuel again.
with such a system you can almost run the car totally bone dry on fuel before surge sets in and starves the engine.
