For racing look at rraiderr's recommendations. Although there are racers using HDEOs with good results also. The question you need to answer for that application is what is the maximum oil temperature going to be. Synthetics provide about 30-40 degrees celsuis more headroom over dino oils.
Gauteng, South Africa weather:
Dry winters with chilly mornings - temperatures average between 5 and 19 degrees Celsius.
Warm summers with balmy nights - temperatures average between 17 and 28 degrees Celsius
EDIT: For racing HTHS is also worth looking at.
So if I use the normal Shell Helix 15w40 that I have been using on my car it would be fine? its not a Synthetic oil though... But its is more expensive than the normal car oils...
here is a links :

If you guys say its not necessary to use these expensive oils then Im starting to wonder why are they so expensive then....
