can anyone tell me how much power would you expect from a fiesta 2.1 16v doch zetec turbo running on on two bar of boost?

i have just bought a lovely fiesta turbo, the car is currently running on 1.3 bar of boost and is pumping out 274 bhp and am just wondering wat kind of power would she pump out if it was running on 2 bar.
the guys at frankinstein motors sport said that the engine is capable of 2 bar of boost. they did the work on this car.


so tell me your thoughts......
