So I bought a big bore throttle body a while back and just got around to comparing it to the stock one. Stock body has a hole in it. What is the function of the hole? To keep the idle stable? Do I need to put one in big bore? Inquiring minds want to know.

"The hole." Answer me this:
Can't the idle bypass screw that you use to adjust airflow at idle do everything this hole does, but with adjustability? Of course it can. I guess it's about a similar baseline. I've seen people tape over that hole to try and slow a fast idle. LOL |
