Throttle bodies - ported and beyond?
Just had a couple quick questions.
Stock LS3 TB is how many mm? VMAX ported TB is how much larger than stock? At what mm is a tune required? At which point is it best to save it for Dyno tune day? What is the HP gain difference between a VMAX and a 100mm + TB? What besides a tune if any are the required accessory mods to a TB larger than 100mm? We'll that turned out to be more than a couple thanks guys

Lol
They have a nice swirl on them though, these don't add hp BUT throttle response is better.

Any point in any build to going to a 102mm? I'm spitballing here but, supercharged or high hp NA? Just trying to figure out how crucial it is in any build. Thanks again, its been 2 years since I last had my SS, so I'm just trying to plan ahead for when I can get back into it.

Your 90mm TB and Ls3 manifold should be ok for heads and cam.

Stock TB was "oversized" by GM Engineering & easily supports up to 650HP.....do your research.
