I'll take a wild stab in the dark and say velocity will be 650fps.
Even with the 300% spring, I was powering it with a 12V and Systema Magnum motor. I'm sure the same setup can crank a 400% spring, but you'll definitely have some serious durability issues in the long run.
If you want velocities so high, why not just pick up a Tanaka M700 series bolt action rifle and install the G&G Power bolt? You'll easily hit 800fps with propane, and it'll save you tons of money and headaches.... it will also perform much better. Bolt actions are inherently more accurate and quieter. The only feature you lose is the semi-auto fire.
As a field gun, the PSG-1 is one of the worst guns to do up, due to the wobbly body and the inherent limitations of applying high velocity upgrades to the auto-electric system. I always tell this to all my clients who request to do the upgrade: Unless you REALLY LOVE the PSG-1, it's a lot of wasted money to achieve a goal that you can get elsewhere for better and cheaper. There's a certain coolness factor versus cost benefit ratio that needs to be weighed on the owner's mind.
As cool as I think the PSG-1 system is, I can't honestly see myself ever using that gun as a field gun.
