Ok Guys, Found some great info.
I tallked to the director of the Turbo Lab (old professor of mine) at A&M and he refered me to a world renoun expert on mist cooling of Gas Turbines Cyrus B. Meher-Homji who works for Bechtal in Houston and is a cheif engineer on turbine technology for ASME (American Society of Mechanical Engineers). I sent him an email today and I am waiting for him to reply but in the mean time I found this great paper on the topic. http://www.meefog.com/downloads/308_...sideration.pdf The important section on erosion is on page 3 section 5.1 which basically says that several studies have shown there is nothing to worry about, as a matter of fact it can take a dust particle up to about 10 microns in size without errosion, so it can clearly take a water droplet of much larger size so the conclusion so far for me is do it but I will continue to research this and see what Homji replies because I gave him the specs to our turbo and rpm we operate at and the meth systems we use. Now I want to research how much the intake charge will cool from a notrous mist shot and what effects that will have on the metalurgy, becasue Notrous colling > meth colling |

as i understand "pre-compressor" is the nozzle in the intake pipe. but we have twin turbochargers, so you would need 2 nozzles "pre-compressor" and 1 nozzle "pre-tb". is that ok?

OP, how about changing the name of the thread to "pre-turbo meth/water injection - big turbo potential" since that is what we are really debating, it will help to get more exposure And discussion I think, maybe not, Just a suggestion
