I'm running 22psi boost, and the pump is at 72psi full voltage (5 bar). You can go crazy and calculate VE, but I believe I'm at 0.58ish BSFC.
Keep in mind I'm also injecting about 1400cc of meth and water, which take up some of that space in the combustion chamber. How much? I don't know, but you can divide by 6 and back-calculate if you feel all the girls at the pub are too old for your taste tonight
