What are the two holes inside the throttle body for? They seem to direct air into the intake but not through the primary intake manifold. Any ideas?

I am going to put my car on a dyno tomorrow for a base run, then install the following and dyno my car again. My first dyno run with 1100miles yielded 204.5hp and 137.7ft-lbs. Now I have 2700 miles and hopefully a couple of extra ponies will show up.

A couple of pics regarding the TB (not from my car):

 

the engine needs air while idling it's a bypass around the valve for idle airflow.

 

Thanks!! Makes sense, now that you mention it.

I thought that the throttle valve was partially open.

Nice cool engineering trick!

Jose,

Did you dyno your car with the Throttle body upgrade?

 

Not yet.

I bought a fuel pressure regulator from a member on this board who is out of town and he forgot to send me the fuel rail adapter. I am waiting for him to get back and I will dyno the car.

I wanted to dyno three mods at once (cheaper).

The TB is installed. Pretty easy.
