B20A top speed
What sort of top speed would be expected from a B20A with the M40 gearbox?

Realistically low 90's. Maybe 96 on a good day. I'm sure someone will say that they get over 100 but the original road tests don't say that.

Thanks Derek. Something to look into, very much doubt I would get 90.

I've not as yet wound it out to see what it could do but doesn't have much top end.

If your engine produces its max power at say 5200 rpm and you are already doing that at around 85 mph it won't go any faster except down hill .

Doesn't really have much pull above 60 so really wondering would it be capable of winding out to that sort of speed or is their an issue.

there must be an issue , its unlikely to be a worn engine . it should do 70- 90 with little stress , the twin carb B20B would do 115 + mph
