• advantage of the power/weight ratio will diminish (talking about highway pulls of course) after certain speed say about after 70-80mph since after that HP will start make up for the difference and after 100mph more powerful car will almost always walk away (opposite can be said for the lighter cars at the tracks with tight corners, if we think about it; Lotus Elise doesn't really have a good Power/weight ratio compared to big dogs.. say for instance than a Challenger Hellcat, but it will possibly kill many of them on a tight/medium track since weight advantage overcomes the other disadvantages regardless of the power/weight ratio)
  
  
• gearing advantage in stock form slightly becomes a disadvantage with the added power, if the boosted BRZ/FRS makes more than 300whp having a slightly taller tires might be good way of cheating if taller gears is not an option
  
• OEM power (especially in NA form) is a lot healthier and more repeatable so after a couple of pulls car with an aftermarket FI kit will start losing power due to overheating (even with the best cooling methods), of course Rotrex kits still has the upper hand compared to turbo (since heat soak is not an issue like a turbo) on that department but still subject to the shortcomings I mentioned above

with all that said, with a proper cooling and supporting mods, Rotrex SC'd FRS/BRZ still has a huge advantage on a track but not proportionally with the power it makes on a dyno since real world power will suffer from..this is just another example of the power on paper and power on real world conditions

Damnit....so what do I do now? Edelbrock, JRSC, or sell for an E92 M3 like was about to?

lol, thanks.
