RJD Tempest
Even though the RJD Tempest looks like a classic tuner job on a C4, the engineering and amazing power levels make it a cherished part of Corvette history. Built in the UK, the Tempest was a supremely re-engineered car with supercharged or turbocharged engines, a special drivetrain, and amazing performance. The RJD Tempest was considerably faster than anything Chevrolet made in that day (via Classic and Sports Car).
It had a different front and rear end, but the most significant difference was under the hood as it could be had with a 6.3-liter V8 and up to 538 hp! The 0 to 60 mph time was under four seconds, making the Tempest a proper supercar in the late ’80s and early ’90s. Unfortunately, with such performance came an outlandish price, and only 35 cars left the factory.
