I am getting set to inject a v-8 duramax turbo-diesel with WI, also pre-turbo and post-CAC (charge air cooler, IC, sorry about the language). This is a workhorse vehicle in need of supplemental cooling in extreme conditions.

Your charts will be helpful. I have set out to use a modulated 1st stage for water savings and activate the full 2nd performance stage with a throttle switch. The modulated 1st stage might consist of 1 .3 nozzle pre-turbo, and (2) .3 nozzles post CAC (or just post CAC nozzles). The performance 2nd stage might be 2 additional .3's pre-turbo.


thoughts?

Thank you for this research.

Thanks

I think a rpm switch and/or throttle position switch is a good idea, to restrict low boost, low rpm injecting when the size of the water droplets could prove to be too large.
