sure it would be awesome on the race track but without turbo it will be hard to get the power out by revving it that high on the street or even from bend to bend on a canyon road... apart from muffled sound and lower rev's turbo is better for performance. one reason the car is cheaper than competition (at least MSRP wise) is the engine isn't really all that high tech, brute force displacement..... for pure sound and rev's I'd pick an R8 V10.

I am interested to see how it does on the track, I have a feeling it is still slower than a less powered Porsche...it's still GM.... regardless of performance it will be a classic and a good long term investment if one can keep it pristine.
