No, those were in the past =) See: http://www.80tq.com/images/20vt/80tq_455whp.jpg
In order to make this much specific power out of a 2.3l motor, the only way to achive this is to move the powerband up.
Again, I want to empasize^3 that this is a demonstration of peak power, not low end driveability...

Yes, we have traded for tremendous top end power as you can tell.

No, unless your idea of "accelerating through traffic" involves 100+mph whenever you hit boost. This is a race car motor, not lugging around in traffic.

It doesn't do well in traffic, I'm not using the car to commute, its an experiment. However, should one decide to, this would decimate any car on the street in a twitch of felony.

Yes, send them to me.

Will do! Look forward to more mind bending, "peaky" power from this experiment.
