Ok, I'm not much interested in Vipers, so had to actually go and do a bit of research, but what I found says that a Viper has an 8.3 liter V-10, which means38% larger displacement than Joe's LS2. That right there says it makes about as much torque and power as a supercharged LS2 at low rpm, as a supercharged LS2 picks up maybe 30% torque at any specific rpm via supercharging, at best, which means 6 liters converts to an effective 7.8 liters - still short of the Viper's 8.3 liters.

Confirming that, the Viper makes 510 crank horsepower at just 5600 rpm (it's a torquey truck engine remember?), and peak torque of 535 ft.lb at the crank at 4200 rpm, which with the manual transmission means 468 ft lb at the wheels.

Finally, the Viper weighs only 3400 lb. versus the 4800 lb or more for a supercharged SSR (the supercharger kit adds 100 lb to the stock weight). That means that the Viper needs only 3400/4800 = 70% of the power of the supercharged SSR to accelerate as quickly. That means, it beats the supercharged SSR, rather easily, unless we somehow pump up the superhcarged SSR to over 725 crank horsepower. And that's assuming the Viper is stone stock with not even an aftermarket exhaust.

Yes, it's nice to dream, but the SSR's weight is frankly, a killer in any street race.

Maybe this is why Joe is planning to sell his SSR and build a 32 pickup with a supercharged LS2 and not much bodywork or anything else?
