what kind of jet were you using. did your compressor wheel get pitted?
it is said they move at supersonic speeds and any object other than air
can cause damage to the vanes.
were you using tap water? distilled water should eliminate mineral deposits.
in FE engines you might find better sucess using water vapor instead of spray. |
the jet comprised of just a brass hose barb with its end brazed up and drilled with a small numbers drill (It was long time ago the size I think was "around" 0.015-0.020" )
The turbo was Rajay size T03 with .25 exhaust housing (smallest at the time) . Never had problem with corrosion .
I did use tap water and with windshield fluid added to stop freezing .
The turbo was horizontal with my intake adapter basic 90 deg with a weber progressive 2 barrel carb . I am not sure the water spray was directly hit the wheel before hitting anything else but it was nice fine spray .
Without it I could only run around 10lb and back then there was 96 fuel .If I remember I was running 9.0 CR I later went to 7.5 forged turbo pistons cause had problems with top land cracking on cast pistons .
