on a street car twin staggered throttle bodies are best as it make the engine much more driveable with no hesitation or the smallest single that works in your rev range{needed cfm}. for drag racing the bigger the TB the less restriction hence no restriction, but it makes the engine flat up till 4000rpm as e.g. a 1.6 litre engine with a 75mm throttle body will have the same air able to flow threw it at half throttle as the nomal 100kw one at full throttle. so feathering the throttle is not very easy at all!
whats called an ON or OFF throttle, which makes them crap to drive on the street.
