I'm curious, what kind of power are you making-and what is a "DSM...?"
I also think a lot of those highly tuned turbos do very well at the track with benefit of extensive cooldowns.
200+hp per litre is obviously possible-but not easy to attain even under the best conditions-and I feel it is seriously doubtful on pump gas.
I've seen Grand Nationals turn helatious times at the strip (with bags of ice sitting on their manifolds & intake tracts!!) and become pigs in 70+ degree weather under street conditions.
The LS1's suffer a bit from heat soak-but only in the 10-20 hp range-where some street vs strip blown motors can lose a second or more...
Also, I can only wonder about the car's driveability. And the AWD concept is nice, but that car comes within 100-150lbs of most 'vettes...
