A quick Google suggests that the top speed for a Chummy is a shade over 50mph. With a 4.9 axle and 19” wheels that equates to a little over 3000 revs.
My Special with a 5.25 axle has a 1 1/2” crank and other go faster goodies. It has been balanced and I’ve cruised at 50mph (3500 revs). At that speed the car seems to have some in reserve. The driver does not!
As Dave has said the A7 is self limiting …….probably more by the driver tolerance than engine strength!
Cheers
