Right, im looking at water/meth injection for my 325 tds, ive done various mod's to it so runs a little hotter however i would like to reduce temps as i know these heads are prone to cracking through heat increases, i hear alot of conflicting stories about them....firstly
1) what is better, water, meth, 50/50 water/meth?
2) are there any power increases to be had through doing water/meth injection
3)where is it best situated, after the IC or inlet manifold?
4) as its water, would it raise cylinder compression? im already running 1.5 bar boost so want to avoid anymore abuse beeing chucked at the cylinders
