Survey! What % do you inject and for what purpose?

[dsmtuned]

I thought it would be helpful if we each listed a few stats about our WI setups and uses for WI;

1) What percentage of fuel is your total injected water/alky?

2) What is your goal in using WI, ie- primarily for cooling intake air, for knock reduction, for reducing cylinder temps/EGTs, a combination of these, etc.?

3) Probably we should list the application too, ie- brief discription of your car?


I'll start.

1) I inject 50/50 distilled-water/methanol at 20% of my total fuel at WOT. I have a 2 stage homebuilt WI system triggered at 8psi and 16psi.

2) I use WI primarily for knock reduction because of the stock IC. Soon I will install my large FMIC and experiment with pre-compressor injection.

3) I run 21psi of boost with a puny stock intercooler on my 2.0l DSM at an altitude of at least 5280ft above sea level.
