Big turbo questions (N55)

Been curious recently, if you go with a big turbo on the M2 will it decrease low end torque or power? So off the line will you have less pull but with high way speeds have a more powerful car. Or will it all around have more power without taking away anything from the low end?

Does the type of turbo affect the above question? And if the end goal is ~500WHP whats ideal? FBO/Pure stage 2?

Additionally, if you build an M2 N55 to lets say 500+ WHP. Does a spun crank hub become a potential issue if youre in a DCT?

Thanks guys

Pure stage 2 is the perfect balance between good low end torque and high HP

I dont think upgrading the crank hub is necessary for this kind of build
