[Diy_efi] "Wet" Manifold Questions

[Kenny W]

The below is the exact same scenario I used, so 
obviously I agree wholeheartedly with all Stephen said. 
The omission of intercooling is not an option for any 
serious forced induction engine. I'm in the process of 
turboing a 2.3L four with 10:1 compression and it will 
certainly have both intercooling and waterinjection. 
10psi will equate to about 270hp in my case,so i don't 
know it I'll be able to run that kind of boost- but the 
priniples will hold true regardless.
