Thanks Eric, i love it too
Good stuff Rhys. More practice and more practice. Looks like it was a little dark there too or you had an ND on that could be making the photos soft? Remember the faster they are going, the more you can raise your shutter speed. E.g. Car going 100km/h i'd shoot at 1/30th, 1/40th, whereas at the drags, they are hitting 130'ish km's by mid track (for the average car) so by the side they are side on, you could shoot them at around 1/60th -1/80th comfortably and still with good motion blur.
