my vRS which has a better drag coefficient than the GTI was pretty much maxed out at just over 172 no way was there another 14mph, and considering they share the same gear box id agree with RR tbh. more power wont make more speed, its the gearing thats the limiting factor, more power will make it reach the vmax quicker thats all
I would have agreed, but according to the UAE prince its possible, his limiter has probably been raised a fair bit though.
His cars on youtube, its good to watch.
EDIT,
Hes on a dsg box, dont know what difference that has on gearing!
