Not sure I am understanding you - do you believe that the NA Kappa is much easier to drive than the turbo Kappa?
Yes. My '06 was easier to drive on a track before the turbo kit, and more so than my GXP.
The NA was less entertaining due to being WAY, WAY underpowered, but much easier. By "easier," I mean more predictable
. A good driver that's familiar with their car will compensate, and do well. But, and I hope you'd agree: having a jerk in torque when you're approaching an apex is not ideal.
On the other hand, there are many examples where this isn't a big deal, like the late model Boxters with turbo 4's. The engine architecture and management system are so good that lag is barely perceivable. Again, they did their best to make it act like an NA.
The electric assist systems mentioned earlier attempt to counter lag by sending compressed air into the intake before the turbo spools up. (My understanding is that they generally fail in just about every way imaginable.)
The difference between the BMW you mention and the GXP is lag. Sure, it's a really freaking heavy car, but...
The GXP has less lag. But, it's still there and, in my opinion
hardly qualifies as negligible. My original point: I'd rather have no lag at all, which means alien technology, nitrous (blech), piping intake through a parallel dimension, or: an NA swap.
