What cam and follower does your brother use in that monster engine? Most people tell me the original followers are only OK up to a point, and for serious horsepower the design has to be changed. As there is not too many options available for changes within the timing chest, it would be very interesting to hear how he overcame this particular difficulty. Knowing nothing at all about sidecar speedway, am curious to learn whether it is usual to change gears during the race, or is it mostly run in one gear.
Love the open pipes, must sound great in the confines of a speedway environment
