Wow, no matter what forum you go to there's always these sort of arguments
Guy in a Golf GTi was behind me today egging me on round the A406... Now, as I came up to the A12 I was pulling off so I shot forward a bit and pulled in. Of course now he carried on foot down well off into the distance.
Somewhere, in some forum on t'internet, there's some guy going on about how his 2008 Golf GTi 'Totally wasted' an e92 M3 on the A406 today.
The difference in perceived performance is affected a lot by your view of the world though - I.e. where you're sitting. A few years ago a number of us from another forum went for a little drive around Buxton - me in my heavily mod'ed RS4 (running about 450Bhp, dyno verified) and others in S3s, some S4s.
My perception was that while I was a bit faster on the runs then the S3/S4s of this world there wasn't much in it. Mate's perception (backed up by video) was that everytime I floored it I just shot off.
Same thing, just two massively different perceptions.
I don't for 8 seconds believe that a mod'ed 150 golf can do an 8 sec 60 to 100. Even if you used the video to 'time' it you'd have to take into account the over-read on the speedo or use a GPS. I'm just not buying it.
