Just digging this one back up :smile:
I`ve been running 10psi with my 350cc fuel injectors at 100%dc using a 0.8mm water jet on an earl race pump and it behaved fine, no knocking and 45c MAT with no intercooler.
Upgraded the S/Charger pulley and I`m now at 1 bar boost, running 500cc injectors at 80%DC, MAT`s over 50c so I`m going to try a bigger jet(s) first, if that doesn`t bring the MAT down enough I`ll be into intercooler teritory.
Just off to dig out the flow vs jet size graph on here..
