You need to really ask yourself how you plan on boating. In your first post you said "I plan on going on day trips of up to 150 .." The set up and horsepower you have been talking about is just not practical for long runs, you need the reliability. Tough to have it all. Tough decision ahead of you, run with the "Big Dogs" or enjoy hours of boating with family friends.:cool-smiley-011: |
Once in a while i would like to go on a day trip to AC (75 miles away )If the engine is set up and tuned and maintained properly why is it not practical.In the Vipers some of my friends make WAY OVER 1500 horsepower in a 500 cu in engine (twin turbo ) in a car thats so streetable that their girlfriends could (and do ) drive from NJ to Calif with the AC on.I hear of boaters who run the Merc 1100 package that have no problems doing the above.

Alot of these practality problems may arise from owner incompetance in regards to operating (ratio of time at full throttle) maintaince or lack of ect.People blame the engine not themselves
|
1000hp is asking alot out of a 572ci marine motor...if this is the first 1000hp boat motor these guys are building there is going to be an expensive learning curve.

CMI Elbow Tops. Sorry phone pic. I got 838hp, similar boost 93 octane but on 580" 580" tall deck bowties, 4.50 Callies Cranks, 4.530 Lunati pistons (8.3:1), Oliver Rods 6.70, Merlin Iron heads 345's (bowl blend and mild ports, Crane solid roller, std. holly 750 carbs, hampton 8-71 blowers, 32-34* timing, power peaks at 5800. I realize that I left a lot of power on the table with the small blower, no intercooler and iron heads but we used everything I had and I can't ask for more!!! I could make more power and run it on the ragged edge but I like to go boating every weekend!. The cam isn't crazy for a solid roller either.
