Been abroad for some weeks so I had to abandon the build for a while... Now that I'm back home I can go about putting the pneumatics together and hopefully give it a test some time soon.
​ I'm replacing most components from the previous set up which had an empty weight of 3.7kg. The new set up weighs in at 2.6kg, that's a weight saving of 1.1kg, not bad eh!

Flow should improve as well - I'm using a different type of QEV which I had to modify to fit in limited space available (basically I had to plug the inlet and drill/tap a 1/8bsp inlet at the side) The smallest restriction from buffer to the ram will be 11mm as compared to 8mm of the previous setup - that should in theory help as well...

Some photos of old vs new QEV, old weighs 310gr, new weighs 120gr

And connections from buffer tank to ram
