Russ,
I have the Hydromotive nose cones on mine, I can't tell you how much it helped because I built the motors and put on the nose cones in the same winter. Tom at Hydromotive recomended them so I went for it. Jeff

Jeff that's good enough for me. So far the guys at Hydromotive have been RIGHT ON with what they have told me. I mean they hit it exactly with the props. How did you install them, particularly what did you use to "feather" the edge in, marine tex? I want to try to get 600, or a little better, out of each motor without supercharging if possible while still being reliable. I can't afford exotic motors that have to be freshed every 50 hours. I need something that with good routine mainentence and not abusing them will hold together. What would your guess be for top speed with say, 625 a side? My goal is 80 or a tad better. Russ

then again, maybe a set of prochargers would accomplish what I want set at around 5 psi. I'm' open to suggestions. I'd really like to see mid 80's if I can do it reliably.

Here are some pictures of the frame of my race fairing mounted on the boat. The frame still has to be fiberglassed, smoothed and painted, but at least you can get an idea of what it will look like.

The fairing looks cool. I'd like to do something similar. Pleae post pictures of the finished product when you can.

Russ,
RedDog382 would be the one to tell you about 600+ HP, I believe he had approx. 630 HP and broke the 80 mph barrier with his 311 . To get over 600 HP with the 454 naturally aspirated you will need high compression and higher rpm that will only help on the big end because you will have to run a lower pitch to get the rpm. Don't get me wrong, I love HP but a high torque motor can turn big props and get a good midrange and have the reliability we all need. I never ran a blower, but to get the numbers you want from the 454 and keep the rpm down you might need to go that route. Jeff

Russ-
What RPM's are you running at WOT? Seeing that you are planning on doing all this motor work I don't think that you will be able to spin your props anymore? I was wondering if you would want to part with your Hydromotives?

Jeff, what exactly do you mean by "high torque" motor? I'm guessing cubic inches. I'm hoping Innovation Marine can give me a few choices. I don't want to lose a good cruise speed for a couple mph on the top. And reliability is the key issue. I'm not sure if it is worth building up my motors or just starting over. Any suggestions?

As you know, all boats run a little stronger in salt water than fresh.

Thanks, Russ
