Well, today was SLOW at work so I decided to play around with some stuff to see if I could calculate the difference between a 90mm and stock TB. I was am still not sure that the calculation will work but tonight will tell. I made a simple spread sheet to calculate how many cubic inches/mm/cm the 90/stock TB are open @ closed throttle and in degree increments the new area. It looks like the calculation will work as it closely follows the stock table. When I plotted the 2 tables side by side it showed that the 90mm TB's numbers were exactly 2.05 times bigger than the stock 75mm TB and needed a correction factor of .4869 across the board. Referencing that back to what everyone says about shifting the cells right, the calculation seems to be correct. Input is welcome.
