Yeah...you had at most 300 HP to the wheels (Generous) with a 3.55 rear end.
You were going 200 KPH.
I'm gonna play devils advocate here, just for a different perspective.
My Dads Cobra rep has a Ford Windsor, which was originally a 5.7. Ford motorsport heads took it up to 6.0 for less than a grand. A nice Holley four-barrel costs less than £100. An increase in airflow and massive main jets, combined with numerous other small mods, all of which will set you back less than £2k and you'll be looking at 400bhp.
Back on the sensible side, supercars with 400bhp can get 200mph. That thing above has the aerodynamics of a brick with a sail on it and, even stripped down, will still weigh as much as a small moon!
The speedo may well have claimed 200mph, but my old GpZ500 once registered 135mph on the clock, when it had a max speed of 123mph!
My bike is bang on (tested), so I know what I'm getting is genuine.
