i was using a stock 4.6 elbow and T/B.i just switched to 75mm and better elbow. i can make WAY more power putting an 85mm throttle body off of a 86-93 stang, but i am sticking with this to keeping it under the hood. i can always change direction, as i have a 4" cobra"RR" hood my infamous "Ford parts black hole" shed. if i can reach 11.99 or better this way i will stick to it.
i ran 82mph in the 1/8th with the 65mm and crappy stock elbow.
