Why does the bbk 52mm throttle body have a upper hole above the iac passage that goes nowhere? It just dead ends into plenum.

Re: Curiosity
Interesting, don't feel like digging mine out atm but I'll prob epoxy it up when I smooth things out. Hate how they leave things so rough on the newer version but I got a good deal on it.
Casting was used for LT's and maybe other apps, so all could get the same basic machining.
edit: LOL actually just remembered that I bought some stuff to deal with that hole already, Think I got some alum bar stock and was gonna green loctite it in. Funny how I forgot bout that, it's been a few years since I looked it over But now I deff rem planing to fill it. Time flies!
