I've been involved in the building of my share of Asian hand grenade motors.
Yes, it is certainly possible to run enough boost, Nitrous, methanol, etc. to get impressive-sounding hp numbers.
But there are several major issues: getting the power to the ground, engines that self-destruct, and high hp with low of torque and thus unusable performance.
I respect some of the efforts I've seen, much as I admired muscle cars with Holley double-pumpers, 6-71 blowers, and radical cams.
I've met a few clueless muscle car & hot rod drives as well. Usually at car shows - people who bought the car as an "investment" or paid someone else to do all the work. Like the guy 3 weeks ago who tells me his '58 vette with a stock '95 or so 'vette engine and stock '58 drivetrain is worth high 5-figures, low 6 figures and could break 12 seconds in the 1/4 mile....
I'd much rather have a more mature, well-engineered, historically significant car.
911 ...there is no substitute...
