Engine: Vacuum Readings, R2

[2R2]

Just curious, what readings on a vacuum gauge at idle are people seeing on a stock R2? Since I am asking questions, do you see a real advantage of keeping the vacuum throttle kicker on a R2 4-speed car? I still have it on my car, but not really sure if it is needed.

I can see how it definitely would be needed on an A/C Car and or Automatic, but a 4 Speed? I can't see the need, they MUST have had a reason. It would seem that the rougher idle caused by the Performance Cam can be controlled with the faster idle speed.

I've never used them on anything.
I've never had a problem after removing them from any engine in my almost 50 years messing with cars. They just seem to be in the way.

But that's just me.

I have kept the kickers for the simple reason of running out of road. Let me explain , I wind it up to feel the punch of the boost to kick in, hit the next gear punch it again and so on . Now I am doing 60 plus(and running out of road) let off and the throttle is closed, I have 25 inches of vacuum under the carb.( sucking engine oil into the compression chamber, not a bad thing) and 6lbs. of boost above the throttle plates ( putting the sealed carb gaskets to the test (also not a bad thing ) but the flapper valve seems to take the brunt of this .they don't last that long . I think the kicker is to soften the and ease the harsh effect of de-acceleration
until the boost drops . This is what I think
