The 1991 Callaway Twin Turbo Corvette (RPO B2K) with the 100 Plus package. 525 hp and probably close to 700 lb-ft that you could order at a dealership, thanks to SledgeHammer pieces added to the 403-hp and 580 lb-ft B2K package. A Corvette “GNX” if you will. Not bad for a pushrod V8—born in 1954 with an added fuel injection system from 1984—that came in a factory-warrantied car and passed 1990s emissions standards. The Aerobody aesthetics are a bit polarizing, complete with a zany 90's purple, but I could look past any misgivings.

Is this the same twin turbo corvette that got absolutely smoked by a stock Buick GNX?

In short, no. The GNX was a great car and would beat a regular ‘Vette but a 300hp Buick is not faster than a 500hp Corvette.

I’ve read that the B2K in this video is an ‘86. That was the first year for the option and a 345-hp package. Combine that with a manual transmission and it wouldn’t really have a good chance against a GNX in its element. I doubt any ‘91 wouldn’t have much trouble, though the GNX is an impressive beast.

I think of the B2K as much like the Grand National (added perf. option package), with the 100 Plus being comparable to the GNX with aftermarket companies testing the limits of a production car.
