I wouldn’t want to go much faster than that in an e85 roadie tbh, hardtop or not. Getting mine up to 240 down Dottinger was scary enough.![]()

It was then taken to get the throttle deresctricted (only 63% max standard) and it hit 517bhp on the dyno. Never did get to try VMAX afterwards. A monster engine that was still detuned in that state.
Agree. The first time I did a vmax run in the MC it was fidgetty and scary.Barty said:Chris_D said:I doubt that was its vmax tbh. It was still climbing when he lifted.

The E86 doesn’t fare much better at such speeds.

This was taken by my passenger seconds before the headlight service hatch decided to request asylum in Germany. The front-end feels slightly floaty at those speeds (250 indicated, 238kph actual speed). Does feel stable until about 220 though.
As for the V10 powered E85: no doubt that it could break the 300kph barrier with the appropriate gearing. It’ll probably feel much more stable though, because like Chris says: you’d need a set of seriously sizeable cojones to get up to those speeds in an E85… With ballast (gratuitous hyphen anyone?) like that on board it shouldn’t be an issue :lol:
I’ve once had the pleasure of taking a 458 up to 305 indicated: mental experience. The sensation of a proper V8 screaming away behind you, everything under full load…

Now that’s an engine with insane potential. Still one of the dirtiest engine sounds out there 8) Can only hope it was replaced by something equally mad?
