I am running a similar kit and I will post pics tomorrow in the day light (worked on the thing all day long) I am running 10gph nozzles and I accidentally set it off at idle and it loped the motor pretty good and then steadied out. I have a few kinks still with leaks and what not, but the egts seem to stay low. I am running small nozzles right now and will do more research first about flow rates on "real" kits from the alcohol injection compaines. Any more information on nozzle flow rates and what works, that anyone has Im sure jibmaster and myself would appreciate it
