I was a reactor operator (nuclear propulsion plant). If I'm an expert at anything, it's boiling water! :lol:
So cool (or hot). Not many people realise that nuke boats are driven by steam engines that get their steam from the ultimate kettle!!!

There was a huge public outcry here in Canada when we were planning on buying nuke powered boats - most people I spoke to automatically thought the nuke part meant they had nuclear weapons. The general public are friggin morons at times - given that our huge northern border is under ice most of the year a nuke boat is the only thing that can effectively patrol up there (although I have no idea who were defending against unless its guys like you :wink: )

For what I remember some years back. I did a calculation by using the stock VAM voltage numbers vs. air flow at a certain rpm. Subtract that to the size of the motor (100% possible air) and these where the numbers I was getting thoughout the RPM range.
60-1, ATR manifold, modded Conquest IC, 3.5" custom upper, fully gutted lower, Crower rods with all the goodies, Dimond ash strays, 3" exhuast, 30 PSI+ baby!

Why don't YOU do the calculation and see what you get for a VE, Merkxrturbo?
Then you can let us know what you come up with.
You've already been handed all the information you need!:roll:
