All 382's have more than 500hp in them! What's wrong with the ProChargers?

Bought the boat last month and was told the motors had been overheated and "patched". While they are running fine now the engine work would NOT be guaranteed. (Price reflected this issue and I'm thrilled with the deal I got) Cylinders were "bored" with the pistons in them and several pistons are discolored due to heat. I'm just not willing to make the trips we make (with 3 kids) and have a failure 100 miles from home.
Prochargers do seem to make alot of power but they are set-up very rich and get lousy fuel economy (approx .8 mpg) Maybe this set up is wrong, but I don't want to pressurize the engines. More CI seems to make the most sense because I feel the need to go into the engines anyway.
I figure if I do this right then I'll be able to run 3-4 years (minimum) without opening them back up.

I'm running 600 Volvo/Innovation's. 540 ci/1:47 drive/26.5" pitch. We cruise at 3600/55 mph to 3900/60 mph. Best top end ever is 78.7, but the boat will run 75 any day. DPX drives are a little "draggy" at higher speeds. No boxes - don't make 'em for those drives. Genny, A/C, water heater, 2 full coolers, etc., etc., etc. 1.0 mpg day after day....

Russ,

Boat was set up with the props turning inward when I bought it. Have not tried turning them turning out. Actually like the way it rides turning in.

The curve on my cams favors higher rpm. Actually a little weak on low-end planing, but when R's hit 3000 rpm, better hold on! HP peaks @ 5800, but I'm propped @ 5400 with the 28's.

Probably a little more top end in it with some custom lab work, but the heavy 382's don't seem to respond very well to standard labbing.

575's SCI, extension boxes, Bravo XR, sportmaster lowers with 5 blade (29 pitch) Hyromotive props (not labbed). Depending on weather and weight, I've seen 76-80 mph.

t500 ... sounds like you landed youself a nice one... we were looking at the fastechs before settling on the top gun. I look forward to seeing the boat with your upgrades... I had the same concerns for the long trips we make here in So Cal.

Thanks,
I remember you guys picked up a nice looking Gun recently. Even my wife likes the looks of the Top Guns but the cabins just don't suit us as well with 5 people sleeping in it for several days at a time.
I'll be posting more info as the builds progress, we'll probably be pulling them out of the boat in about a month. What we end up building in the end is what everyone is going to want to know anyway.

I hvae a set of Steeling 12" stand off boxes for sale if you want to change your X while doing the engine project. I have a 96 382 w/ Hp 500's for Florida in the winter and 540's, 600 Hp with little B&M's for the river in the summer - 650 Hp shows 84 mph - this is a non step bottom

Thanks for the numbers. We're shooting for 650HP and with the stepped bottom (2002) I should see upper 80's...I hope

Terry.....did you guys join SCOPE? You are right near me!
