Large Valve small chamber

Lets say that I have a 1 1/2 chamber, would using a 2 in piston valve leading to a 1 in barrel Give better performance than a 1 1/2 piston valve?

If valves were to have 100% effenicy, both valves would preform the same and the larger 2" valve would be a waste. Although valves are a lot lower on any terms of effeincy. So essentially the higher flow compensates for the lack in effeincy. Catch my drift? Hopefully that made sense.

Ok thanks.
So it would have better performance. I wasn't sure because i though that the air going to the large valve then going to the small barrle might mess something up.

You *probably* won't notice any benefit to using a 2" valve instead of a 1.5" valve; a 1.5" valve is already providing as much flow as the 1" pipe can handle. (or pretty close, anyways)
