turbo and WATer injector

[Todd Phenneger]

Yes,

  I've seen that done as well.  Or rather heard of it right here on this very list.  One of our Russian friends had that on one of his cars in Russia.  Lada maybe. :-)   LOL.   

  At any rate,  he had good results.  And frankly, since I have a KH in my 4kq and an MC sitting at home that I plan to build with new pistons, balanced, etc, I plan to "experiment" with water injection on this KH.  But only AFTER I have the MC ready to drop in. :-)  THat will be awhile as I want to design a custom Intake manifold for use with EFI for this engine.  BUt that depends on my results with extra injectors on the KH.  

  Cant wait to play though.

How about injecting water into the manifold instead of fuel. An engineer I
know has done just this on an old Bedford(Yanks won't know what that is eh
Phil etc)truck.. This allows him to lean waaaay down and cruise just fine,
similar things were done in the war too I believe
