Stock Supercharge Snout Size

[naws]

I'm just curious how large the stock superhcharger snout is. I know with heavy porting and possibly some welding it can get to 102mm but how large is the stock size? I'm throwing a cable throttle body on a stock snout (LSA going in first gen camaro) and curious what size would be best. I know I can go with a 92mm but would a 90mm have a better transition creating better flow?

Stock SC snout is 90mm exactly, so I'd say that the 90mm TB will have the best transition for you. But that being said bigger is better, the tb is the bottleneck of the entire intake! It's easy to open up the snout to 92 mm, you could also smooth out a few other things inside the snout while you're there.

Umm, your ruler is not over the centerline of the TB bore. It looks like it may be bigger than 90 mm

Here is a center bore measurement just for Z06 Bryan, no mm gain there, its 90mm.
