[Diy_efi] Water metanol turbo assist - was Argon turbo

[Ohio Benz]

I agree! Someone here must have some more suggestions
based on scientific data?
Regarding matching of turbo to application/engine. I
think there's always an area of sacrifice, you can't
just have it all.  If I wanted to come screaming out
of the hole a small AR turbine like a 48 (for a 2.0L)
will do the trick. However when I hit about 5K, it's
done and opening the wastegate to keep the poor thing
from spoooling to destruction doesn't make any more
HP.
So in order to keep screaming into the 9K redline we
are looking for...it takes a bigger AR housing. Now to
help us get out of the hole we are running a higher
base CR and a head that flows a lot of air - but those
first seconds till we get past 7psi are still gonna
kill us!

Now WI into the exhaust would ONLY happen for seconds
at WOT, ONCE during a pass or hard acceleration. So
washing a turbo etc are all not issues.  Issues could
be the boiling off of the water between the jet and
the check valve - whether that creates a vapor lock is
another subject too.

My question still remains - how do I calculate how
much H2o flow (ml/sec) I would need? EGT will have to
be a factor in vaporization plus an estimate of
exhaust flow under WOT conditions.

Second question is more experimental - nozzle size for
proper atomization.  I'm assuming that once I know
flow, and have a pressure value, this again is a
calculatable item.

So please help me with (still)the first question!

Thanks!!!

Come to think of it, no water will end up in the sump
if its going into 
the
exh housing!! :)

Someone here must have some more info on this (or
around the place) I 
for
one am awaiting an answer, hopefully not by my own
experimentation.
