as the title states im going to put a single throttle body on my VFR and i need to know what size to use.

engine specs are 748cc 11500 redline and i think its 100hp but i dont know the peak.

i searched for the math but couldnt find it anywhere...

apparently a 50m throttle body will get me to 144 horsepower but is that at my redline?


are there any formulas for accounting in my higher redline?

how hard is it to get more than 144 horsepower out of a throttlebody of 50mm? isn't hp also dependant on things like CR and ignition advance?
