LOL sorry to rain on anyones parade but for the benefit of those who didnt know, it was a timing error...
Ive done a 0-60 in 5.57 on 17s with my Clio running around 210bhp when it wasnt in great tune last year, on low boost while waiting for a new chip. My gut feeling is that in a fwd Clio youd probably hit an optimum of high 4s with 250-300bhp. This would be in road spec with 15" drag radials and would have been what I would have been aiming for at FCS this year if I wasnt selling my Clio! It certainly would be possible, but traction is definitely the main problem.
If you were determined to build a 0-60 sprint Clio, youd basically want to run full-on soft drag slicks (not track slicks), put as much tyre width on as possible, try and keep any extra footprint on the inside rather than the outside of the existing track, jack up the rear on big rims and drop the front to the ground with soft suspension.
