And wasn't it $650,000??? In 1992??? I mean come on, that car costs 10 times what this one does.
Engine internals shouldnt need to be changed. On my personal car I went from 300hp to 375hp with just a turbo back exhaust and remapped ECU. So a car with 510hp with that many mods was probably making 600-650hp.

Safety changes was probably a roll cage which might or might not have added weight, not that it would have mattered much since those speed runs are over a flying mile.

But all my trying to get across is the speed run they made and are giving to the production car should be taken with a grain of salt because a production car didnt do 230+mph.

When they remove the speed limiter and dont modify the car and then do the same top speed let me know because that would be impressive.
