I would build the engines internally to be able to handle 700+hp.
Then I would use your 174's and see what they do. I wouldn't do chillers as I think you'd be better off go to just go with bigger blowers if you want more power.
You will probably need more carb. I would send yours out and have them made to 950-1000cfms.

If the 174's don't make enough hp for you, then upgrade to big blowers later.

I'm running 88GPS and they make less than 500 HP now.

Less than 500HP, how do you figure that with 5lbs of boost. That boat has always ran 88 mph with the Hawk 540's.

I forget what were in the boat. I thought the they were Hawk 540's, but could as easily be 525's. I believe they came out of the Hawk Cigarette. Are the Dart Iron Eagle heads still on the engines?
