Hole in throttle plate?

art leong · 03-23-2011, 08:07 PM

I have a .125 hole drilled in the throttle plate (throttle body) of my box manifold.
It idles aroud 2000 rpms. I thought it was needed due to the cams I'm running.
I put the individual throttle body manifold on and the car idles at 800 rpms so it isn't the cams.
The most I can get for vacuum with the box is 70 kpa, the ITB's idle at 50 kpa.
I want to close the hole up in the throttle plate.
What is the best way to do it?
