There have been a fair number of tuners that have made the trek to the Nardo test track in Italy to see if their modified rides could break an illustrious top speed. The MTM Bimoto TT comes to mind, as does AC Schnitzer's GP3.10 3-series, Edo Competition's Lamborghini LP640 and 9ff's insane GT9. Another contender has been added to the list and it's just as impressive as the rest.

Top Secret has been making the show rounds with its twin-turbo'd V12 Supra for the past year, but it's finally putting its money where its mouth is and going for a top speed of 400 km/h (248 mph) later this year in Italy. Breaching 200 km/h hasn't been an issue since the boosted 6.0-liter V12 is supposedly pushing out over 1,000 hp.
