Best Throttle Body Size for Supercharged Fox

Looking for some advise for the most recommended TB and MAF setup. I currently have the

Deatsch Werks injectors 550cc
XL3F-12B579-AA 90mm MAF
BBK Powerplus 70mm TB

I’m thinking I need to upgrade the TB, but not sure what size is the best.

Accufab has flow numbers on their website, find an engine CFM calculator online and plug your specs in and compare. Will mostly be dictated by displacement, the S/C will improve volumetric efficiency so you can be a little undersize and still make the power. Will also help to have an idea what HP you expect out of the engine. You do want to taper down from the MAF size generally but with the S/C you're also not worried about creating velocity. 90mm is a pretty big TB so you'll probably be smaller than the MAF anyway.
