I've used this combination once at the MotoGP in Catalunya last year so not a great deal of experience. I did need to increase the iso to 800 a few times to keep the shutter speed/aperture combination, so bright conditions are ideal (cloudy and raining in Spain!). I was using it with a Canon 60d so had even more telephoto capabilities. As you probably know teleconvertors work better with prime lenses and you may well do better with the Canon 1.4x. I also used the 2x convertor with the Canon 300mm L f2.8 which worked well together.
I'll post a few images of the racing to illustrate later on.
