ToyCam Regular Location: Canberra Registered: April 2003	Water Inj. on 4AGZE Tue, 02 August 2005 12:46 I'm putting water injection on my GZE because i've heard mostly positive things about these systems. There are a few grey points i need a few opinions on though. PLease point out if these are wrong Before or after charger?? Before Quote: Compression in a turbo is usually adiabatic. This means that the air is heated as it is compressed, which takes power from the shaft and requires removing through an intercooler. If you inject water before the turbo, then you can move compression to near isothermal, so very little heat is added, and less power is taken from the turbine to compress the air for the same boost level. You can loose the intercooler and therefore suffer less pressure drop between compressor and inlet. All of which gives you the possibility to get more power out the same turbo. I'm thinking this will be the same theory for a charger, and take less power from the crank to turn. I've also heard that, if atomised correctly, and with a 45%water/50%methanol/5%softener, it can also help the vanes seal better, and make the charger more efficient. The effect of un-atomised water hitting the vanes worries me though After Quote: Here you are adding water to deal with combustion and detonation reduction. Ideally you would inject directly into the chambers to minimise any charge displacement. This way can increase timing and not worry about charger damage. cooler or not to cooler? With water injection, is it neccesary to run an intercooler? especially with an sc12 struggling to push out >15psi. Benefits of no intercooler - shorter intake track, les weight, no pressure drop from cooler, better throttle response... Anyone with experience, your input would be appreciated Cheers Steve [Report message to a moderator]
