Just a quick note about Whizzers, Bonneville, and different motor configurations. I have agreed to run a twin engine Whizzer at Bonneville salt flats in the very near future. The twin engine Whizzer was built by Ron Dow, ownership transferred to Terry McAllister, and donated to me to ride at Bonneville.
It has 2 motors inline, both are WC-1 cases with NE top ends. I will be modifying the motors for maximum power, and expect the speeds to be between 70 MPH and 100 MPH, depending on the amount of modifications.
Another interesting Whizzer is the "V" motor [currently owned by Terry McAllister and built by Ron Dow].
Have fun,
Quenton
