Bobby,
Thanks so much for the help. So, is that 100cc/min? Then in a 15 min race I would only use 1.5L of ADI? If so, I could easly addapt my existing smoke system to double as ADI injection. (It holds about 3 gal). That would make it really easy! I would probably use 2 100cc and turn them on manually at 40" - I am only using the system for a handful of races..
I didn't see just the nozzles on any on the Snow Performance web site. Should I just call them?

Dave,
I’m using an ET150 110V pump with 1/8” NPTF fittings. It’s rated for continuous duty and weights a little over a pound. Snow Performance for nozzles and fittings. I based the controller on the attached pdf. The LM339 chip will allow you to control up to four different nozzles triggered at different MP sensor voltages. So you could trigger a 60CC injector at 36 MP and another 60cc at 40 MP etc. I run one 100CC triggered at 32 MP with no intercooler for climb.

It will be difficult to burn more than about 20 gal per with a rotary. Maybe as much as 30 gal with a turbocharged 20b.

I was seeing upwards of 30 gph with my turbo 13B while running the pylons at Reno. That would be about 45gph with a turbo 20B. Course I was running really rich to be sure I avoided detonation.. Am trying to design a water injection system to use more boost and run a little leaner.
