Fast 4150 throttle body vs 90MM TB and elbow, which is better

[SS-PEREZ]

I suspect the 4-hole throttle body would be faster if that were the only change, but how much better if any would it be?? Any ideas or experience with this? Will be spraying nitrous.

though this is old news i decided to give this a try but i will be going with the super vic instead of the Jr. with a wilson 4500 tb with a spacer with dual spray bars

If I was to keep on with my extended cab truck I'd go from an all 4150 Vic jr, nos cross bar plate, and 4150 tb to a 4500 super Vic, 4500 crossbar and 4500 tb. There's cars that's picked up good et just going to 4500
