Back in the day, whenever someone asked abou using the CSV as an 
auxiliary fuel source, there seemed to always be a chorus of expert 
opinion saying "don't do it."  Part of the argument was the unequal 
distribution of the fuel to the cylinders, the other part was that the 
CSV is very crude, and does not make a nice atomized fuel pattern.

Reading your note above, it just seems wrong.  You are going to use it 
at the time that the engine is most "sensitive," ie, you need the extra 
fuel to make sure you don't get detonation at high boost.  Meaning you 
*really* need to make sure it will work properly, and not leave any 
cylinder lean at any time.

To me, I'd be much more worried about the speculation that it *will* 
work than that it won't.

I'd be tempted to say there is no harm in trying, except that there 
could be.  You'll have no way to tell if any one cylinder is getting 
stressed, and could end up with a broken engine.
