[Diy_efi] compression ratio

[elcamino73]

I just measured my compression ratio on my 407 Chevy which I just got back
from the machine shop. Turned out to be 9.5:1! I still want to do 15 psi @
6000 RPM. Guess I'll be needing that water injection more than ever. I
wonder if two 3800 fuel injectors will be dump enough water into the system.
Anybody with figures on water levels needed for compression/boost/AF
figures?
