Technical question, Stock throttle body size?
Does anyone know what size the stock Throttle body is on the LS3? I am thinking 90mm But not 100% certain on that, Can anyone shed some firm advice on this?
Thanks All; Scottie

So if I was to get a 92mm would the stock computer compensate for the extra 2mm?

i wouldn't waste the money on 2mm.
what other mods have you done that necessitate a larger throttle body? |

Stock throttle bodies are capable of 1500+ hp. No reason to change it

I’ve debated a larger TB myself. But if stock TBs work perfectly fine for 1500hp, why is there a marker for aftermarket? Does aftermarket really have any added performance over stock?

$ to hp ratio may leave you wanting to spend that money in other places first.

I have a 2013 L99 that I have a 3.0L Whipple I just put on a couple months ago and was thinking about putting a 103mm on. Any educated opinions??

Hey there Larry, glad that worked so well for you!! Nice gains for just a TB... Kinda wished I would have just kept it and used it on my LOD just to see what it would do for my setup, but glad it worked well for yours.
