n54 torque characteristic

How do you feel a torque in the stock N54 ? Is it linear (like in supercharged engine) or there is a moment when you feel the torque kick ? Does the car feel quicker due to the torque kick than it really is ?

Generally cars with linear torque characteristic (for example Audi S4 B8) feel slow compared to the acceleration times.

It's a lot more linear in stock form, but tuned there's certainly a swift kick when the torque comes in.

Torque builds from 1500rpm onwards on stock turbos, 300bhp and 400nm stock,

Attached is stock torque and power curve. Its not particularly fast stock.

To me the N54 with stock turbos feels more like a car with a supercharger on it as far as torque goes. Nice and steady pull through the rpms, and the torque comes on at a really low RPM. I'm sure if you went with a big single turbo, it would have more lag, and be a little more "Soft" on the low end, and then build torque when the RPM's start to build.

I love the low-end grunt from these N54's with twins....especially with a good e85 mix tune.
