Hi guys,

has anybody measured with GPS real speed of the car? I'm not sure how much speedo is away from actual speed... I have standard gearbox, 195/45/15 rubber and was wondering how fast am I going at 3rd at 6750rpm and 4th at 6750rpm?

Cheers

It matters not, if the gearbox is the same.

But I see from your profile that it isn't.

my road angel once saw 138, that was 7k on a std gearbox on 16" wheels... and never again. had a passenger to witness too... nearly needed 2x body bags... the steering isn't great at that speed

There used to be a table on the old site, rpm vs speed. Depends what size wheels aswell.

Ive seen 6.8k in 5th with an 11 turbo box quite a few times, 130 on gps, on the autobahns of course. My gtt used to feel solid at those speeds suprisingly.
