Twin Turbo vs non-turbo engine performance?

Hey guys, I'm kind of a newb with cars as I've always driven a beater but I've recently gotten myself a decent whip and am now very curious about cars in general lol. I got a BMW 428i Gran Coupe which has 240hp 4-cyl twin turbo w/ 255lb torque.

My question, and it might be a stupid one since I realize car weight and other things come into play, but at what 'horsepower' does this car perform in comparison to a non-turbo engine? I realize turbo helps merely in the lower rpms, but in terms of sheer acceleration how does my car perform vs a non-turbo engine? Is it like a 280hp, 300hp non-turbo'ed car? Or perhaps hypothetically, how many hp would this car need to have to have the same performance without the twin turbo? I realize this might not have a clear-cut answer but I'm just a noob wondering how it all works :) Thx in advance.
