water injection/ spark plugs
After 7 75% throttle 1/8 mile passes. 91mph on 195 street tires. These are the plugs I started the new/rebuild motor on and they were used. Motor has 1 hour run time. Boost was .9bar. EGT was 675c. AFR was low 11s and total timing was 20deg. Never went over 8000rpms. Two M5 water nozzles that start to come on at 2psi and go full by 25psi with a 150psi pump. Plugs are 9s.
your opinion on the plugs, please. thank you.
