Re: [DML] what kind of turbo?

["Donald Ekhoff" <ekhoff@xxxx>]

Bruce,

I run heavy water injection in my single turbo car. I inject onto the
compressor wheel in the hopes that the water would be atomized there and
cool the entire intake track into the engine as well as helping to control
preignition. I monitor the intake manifold temperature and see it drop
dramatically with extended boost, as when climbing a long steady hill. When
I run out of water, performance drops and preignition immediatly shows up.
At first I used a boost pressure switch to initiate water flow but found it
was to little too late. Now I have a throttle plate microswitch that is set
to immediatly get the water flowing any time I give it enough throttle to
get positive boost. It seems to have worked well for the last ten years and
the plugs always look good. I have not had anything apart to check on
carbon deposits. BTY I use Mobile 1 sinthetic oil. I have eliminated the
cat and run a single transverse glasspack muffler. Only on one occasion
have I noticed exhaust smoke on startup. I will start trying to monitor it
better and report in the future.
