My boat does a max of between 80 and 82 mph in perfect conditions at 600 hp. Using the known value of aprox 17hp per mph for our boats, with you having 100 more hp, that would put your top speed between 86 and 88 mph. I can hit between 79 and 80 most of the time. I have hit 82 once. SouthOCG's boat should be about 6 mph faster than mine.

This was all hashed out before on this boat before SouthCog owned it. I figured it would come back around on it's own :drink:
The boat obviously has 1.36 gears. Bravo One props run 1"-1.5" less pitch than advertised (per Julie) whick makes this all a further stretch of physics.

(By the way, don't forget Mr. T was driving his own marketed package down river in crisp, cool, zero humidity Parker air if my memory serves me well (which is questionable))

My thoughts too Dave. It's hard to fool physics. My boat had 20% slip with a similar setup.

OK....

Just back from Havasu (boat is down there for the winter now).

For clarification.......... Postively 1.50 gears.
I pulled the lower and checked them.

I did have an opportunity to run a -1 while I was there.
The results were close to my 0.

Light load, mid 80's, little wind, 84 @ 5700.
And this is with the labbed B1 26

Took the boat in to hook it up to the computer and it turns out I have a bad IAC and a bad mass air sensor, which is reading the temp on the motor much higher which in turn is changing the curve on the computer.

Ilmor is sending out some new parts as well as a new computer. Parts will be put in next week, I on the other hand won't be back down until the middle of November so I'll work on some new numbers then.

That is awsome that you found the computer thing, and were able to try a -1 lower. Sounds like you are narrowing in on the issues.

Was the -1 worth anything in terms of handeling or otherwise?

Chris

I've got to start over after I put in the new ecm.
Once I've got some good numbers, I'll throw the -1 back on and give it a run.

I will say with the -1, the boat didn't cavitate when it rolled over. Seemed to be a little quicker 20-50 and 40-70 as well.
Didn't need as much trim and my slip was a little higher (10%).

I may run back down next week late to run it again just to see where it's at. From what Ilmor is saying, the new ecm, new iac and mass air sensor I should be able to move through the 5700 wall with ease.

If anyone wants to come and verify the #'s (because nobody seems to think they're not accurate), by all means you can meet me there and we can go for a ride. :argue:

You need a 34 with 710's or a thor then you wouldnt need to try so hard to go fast. I think a thor with a 710 would be bad ass and run way over 100mph.

This coming from the guy who is trying to sell his 525 and build a 1000hp motor.
Did I miss something somewhere?

It's no as much about going so fast as it is about getting the motor to run right/pull the right RPM's. The top end is simply a result of getting the boat to run right. How often am I going to run 90??? Probably every chance I get.

As far as a 34 with 710's..... You never know.

The Thor................... When I was in Havasu last week, I was talking to a very reputable person with "friends" at Nordic and the word is that production is coming to a halt on the Thor. Rumor has it, they're completely looking to re-tool the bottom once again because of performance issues.
That would make 4 bottoms in 4 or 5 years.
The other side of it, who's to say that anyone know's what they're talking about.

Good luck with the boat. I would get a new prop from bronson hill (bravo 1) . If I do put a new engine in the boat it will run over 120 and I will promise that. Look how flat the gen 3 bottom runs with a good driver.

The cat definately looks like it is running flat and fast.... but that is very smooth water compared to what I boat on most of the time.

P.S. One of my favorite quotes...

The true measure of a man or a thing, isn't done when conditions are good, but when things or conditions are poor.
