You are looking at Specter Werks Corvette GTR with a 800 horsepower / 800 torque twin turbocharged LS7 from Lingenfelter. The other thing to mention is those are two-piece HRE CF40 carbon fiber wheels. Those have a full carbon fiber barrel, titanium fasteners, and a 6061 aluminum center, which gives it a weight of 22 lbs. If you are going to SEMA 2009 make sure to check this car out.

This 6speedonline member has posted a very nice and very powerful Toyota Supra. Currently the Supra is putting out 1300 RWHP and 965 RWT. Currently it weights 3480.

Rumor has it Ford is developing a twin turbocharged 5.0L V8 codenamed “Road Runner” for the 2012 Shelby GT500. Estimates put the power at 500 horsepower. I hope Ford is developing it to consume less gas for that level of power because the current 5.4L V8 makes 540 horsepower.
