Makes sense, I was thinking about converting my Cobra regulated FLEX to a WARP so I was curious about a couple things...
1. How much length will the swap take out of the overall length, if any. With the shorter tube of a WARP, your trigger frame from the FLEX would need to be cut shorter or replaced with the shorter WARP trigger frame.
length difference IIRC @ is @ 3" ( Tho don't own a FLEX to be absolutely sure )
2. Will the decrease in plenum volume take away from the efficiency and potential for power. My 30 cal setup currently spits the 44.75 JSB's at 915 without breaking a sweat.
Efficiency Yes & No ... pending you stay within realistic power demands of caliber for the available plenum volume each offers. So YES, going to the shorter WARP air tube your power potential will be less in the larger calibers. If pushed to make the power of the longer FLEX tube ( Plenum volume greater ) efficiency would be worse.
As they say ... there is no free lunch !!
cause & effect of available air volume to do the job of launching more weight pressures being equal, is tied to plenum volume due to the pressure drop within the plenum ( Regulated use )
The WARP run as an UNREGULATED gun does far better in the large caliber / high power uses because the valve gets to use the entirety of the drop block & bottles volume to power the shot.
* But there are Flow losses and the FLEX in the same configuration will still have the higher power potential.
