What are the factors involved when deciding intake inlet size from say intercooler to throttle body? In this case, /6, 300hp? EFI, turbo, 4spd, 2500lb, autox/road race track car. Seems like its a restriction vs throttle response consideration, or 2.5" vs 3" tubing.


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
