I hadn't taken my car to speeds over 240 km/h (147miles) before - and seldom even to 200 - since I had a busted shock in the front and the brakepads were almost finished. Now my car was just out of the shop with brand new tires, new brakes, new front shocks and new miscannellous parts like the GROSSLY overpriced distributor caps and rotors. So I put the pedal to the medal - or actually, it was there already so I just kept zooming.
I got the car easily to 260km/h (159mph) according to the speedo. The speedo shows 8km too much at 100km/h so it was either about 250 (155) or - if that's 8% - just 240 (147).
The car was pulling very steady until that speed and had only 5000 rpm at the "max" speed. Now I keep thinking that either this car did NOT have the top speed governor removed as the seller claimed OR the "Ekkehart theory" is correct and the mighty power of the M70 is not mighty enough to propel this heavy bulk of a car to faster speeds. I'm sure the 255 rear tires had a negative effect on the aerodynamics as well.
For the German 750ers it might be rather commonplace to take the beast to speeds like 250 so my rant might seem pointless (from a German view); but given that Finnish "autobahns" were designed for driving at the limit of 120kmh (73mph) which you can certainly tell by the bumps and the curves, this sort of breakneck speeds are rather rare and seldom seen done even with motorbikes.
The whole point: Ekkehart, you were right and I hereby apologize in public for doubting your 260 MAX vision (several times I think) on the board.
I must admit I got an amazing adrenaline rush that lasted for quite a while, I had to stop at a 24h Shell station to restock on cigarettes and smoke two of them before I started to calm down. Perhaps it would not have seemed as nutty at daylight.
Sure thing is I'm not likely gonna try a stunt like this again in a while; driving in pitch darkness at warp speed ten in a moose zone could have ended in an e32 cabriolet, decapitated Henkka and 600-800 kilos of moose steaks scattered all over the road.
Oh, and the tech data I used in the calculations where I got the theoretical top speed of 282km/h (173 mph): the tech in the car is from a 1990 750i, stock M70 engine that revs 5600rpm and stock ZF4HP24 tranny that has 0,73 ratio at 4th gear, 3.15 LSD factory option and 17" wheels with 255/40/17 tires rear and 235/40/17 front.
