At the end of the day our speed limits are there for a reason.....I see no need to top the N speed limit and i Know for sure coming back form a french car night at ace that my 5 is more than capable of +125-130 but i'd never put that strain under the 1.4 push rod...it's fun enough getting upto 70mph for me
I've gone off the clock with a standard engine and almost standard turbo at 1 bar with the oe speedlines.
She revved to 6800rpm and the speedo just went past 140mph, I didn't have GPS to verify. But I was along side a 2ltr Nova which I know will pull that sort of speed with ease.
What I did find weird was how stable the car felt at that speed, it was perfectly planted like as if I were doing 80-90mph.
I wouldn't do that again, no need for it but it is capable of doing it lol
ive neva topped mine out but i am keen to no exactly what it would do tbh, but 140+ not sure how safe id feel in a crisp packet at that speed lol
just looked at my rr pint out and its 151.6 @7100rpm so think id need more power for 150mph in the real world
given a standard 120hp car runs to 125mph, this will be pretty close, assuming sensible gearing:
130 mph 135hp
135 mph 151hp
140 mph 169hp
145 mph 187hp
150 mph 207hp
155 mph 229hp
160 mph 252hp
165 mph 276hp
170 mph 302hp
I'm thinking I was close at 1 bar then. I did a 14.2 sqm at 1 bar, term of 97mph which would equate to the sort of power that chart states.

believe a renault 5 speedo and you'll believe anything!
i remember JP showing me that vid back in the day
once upon a time my gps said 138 and my speedo said 120.... but why on earth you'd want to go that fast i dont know... i'm never ever going to do a top speed run ever again, steering goes light, everything goes quiet and you feel like your going to die!

lol my speedo never works, i just know things get a bit unstable when its a windy day, going past a lorry at around 5k rpm in 5th gear
oh and i run standard 13s
i've hit the limiter in 5th, which is 7k, on 16" wheels, had to keep it on big boost to keep it pulling, but as i said i'd never do it again, far too small and unstable.
