It is pretty obvious why this happened and it had nothing to do with the 
intercooler.. It was the water injection way too much before there was 
enough heat in the exhaust.. If the exhaust is cold you don't get boost 
period.. Too much water no boost...
I would love to see a dyno sheet of an engine that has an ice water type 
intercooler and proper octane fuel and then the with and with out water 
injection results. I am just not sold on the whole deal for a well prepared 
racing engine.
