Any idea how much of that 95mm is lost to the snout passing through right behind that opening? Everything in front of that doesn’t need to be bigger if it’s getting choked down on its way to the screws.

It widens out quick beyond the 95mm openning but there is allot of meat in there that can be ported out to alleviate any bottlenecks. I opened mine up to just under 100mm (to retain factory seal groove) but have yet to try my 100mm BBK TB on it, still tuning with the 95 FM one. I’ve seen almost 2000 Air Charge through it with the FAS Billet inlet plate on the blower, that was a documented Dyno proven no other changes made not even to the tune 50 HP gain adding that plate and the 95mm FM TB on it. The Dyno chart is before and after the addition of the inlet plate and FM TB
