Real-world experience trumps math any day but are comparitive restrictions in the system a starting point? The combined area of the intake ports are going to be about 75cm2 but the area of say an 80mm throttlebody is about 50cm2. That might imply a higher velocity through the throttlebody than the heads and lots of other variables but would that be a starting point to think the throttlebody might be a constriction?

I'm interested in the comments of the experienced here. I sourced an 80mm throttlebody in support of 500+hp on the track (partial throttle less important) but am always willing to second-guess my expensive purchases
