180mph

i take it they wouldnt look the same because of the cerbera having more inertia or kinetic energy doing 40 than a rx doing 40?
 
The closing speed is still 80mph though which was what i was trying to say
 
This thread is flying everywhere isnt it

Although the closing speed maybe 80mph, the actual amount of energy would be different. (Exponential increase in energy required to move an object at 80mph compared to 40mph)

Classic thread hijack :wiggle

if you don\'t believe the road angel thats fine, but the 157 at indicated 165 was throught timing beams at a drag event - see my earlier posts.

I\'d go along with your figures - I was involved in a magazine article a few years ago at Bruntingthorpe, and with GPS timing gear, my clock saw 160 which turned out to be 152. So 5% overread at the top end, the same as yours.

5% it is then. My car now has a top speed of 0mph so reduce that by 5% = 0mph.
 
I was overboosting thats why i went pop, but i dont know why
