Some help needed
In me friends 91' 520, the top speed is very minimal
It has the twin cam 6 cylinder in it with a 5 speeder manual
First gear in it is like a crawler gear in a land rover, we did a test up a hil with the landy beside it in low range & the bimmers revs and the speed matched that of the landy
When on the motorway doing 70 MPH the engine is screaming at 4100 rpm
Any ideas why this is happenin or are all 520i likes this
Cheers
