Just picked up a Greddy Type S second hand. Now, this thing has two vaccum ports on it. One is on the black "hat" cover and the other is in the aluminum casting part right under the first. Which one do I plug into the intake manifold boss and do I leave one unplugged or not? Pics to be posted later if we need them. Thanks

The engine is in vaccuum because at higher RPM the engine flows way more air than the closed throttle blade can supply. If the intake manifold stayed under boost, the car wouldn't slow down when you let off of the throttle.
Testing a BOV is a little hard, you have to simulate your normal boost pressure on the valve of the BOV(where it attaches to the I/C piping) and then pull a vacuum on the upper nipple. -------------------- Eric Wort
