True, but the guy was a solid 95 and the boat traffic was tough. pretty impressive for a Fountain. He was airing it right out every time I looked over he was all twisted out of shape in the air. Gotta love it.. He passed us going the other way and did what every true motor head would turned in chase, lol...
GPS is still out to lunch, it constantly is sweeping like a reset, I don't have time to mess with it yet. Jason took out a lot of fuel and made some idle adjustments. if it runs like it did today i will be very happy, we maxed 5860 rpm's with 89 gallons and 3 people. Not bad thats where we were with 20 gallons and me alone before the fine tuning. I filled the tank after almost running out and stopping @ 2 places who sold 87... But the dock girls offered octane boost, lol. We found a place with 93 and put 77 gallons in what I thought was a 70 gallon tank. I looked at the capacity sticker and it said 89 gal.. but even better my buddy Brett @ BBLades sent me a prop it came today which should get the rpm's to 6400.... I need to try it tomorrow.. I will report how the weekend goes, looks like a good turn out tonight for my event, the big day with he band is tomorrow.. We have 2 Kryptos which both go over 100. Mike's ran 102 last year and he got a top end freshen and went from 7psi to 10psi netting him about 60hp from 860 to 920 @ 5800. I forget what his rpm was with the prop he has a B1 30. He may need a 32... we will see tomorrow. Ok I just got home from a long day which started @ 5am with a trip to Lake george. I will post after this weekend... You are all missing out,,,slackers.... Good night

Sorry I couldn't make it Don. Flying out to a conference Monday morning and just got the boat back tonight:eek:! Sounds like you had a good run... make's all the headaches seem worth it I bet!

Anyways, I'm just happy I was able to comprehend a long post from you. Those others ones about your engine issues got my panties in a bunch:lolhit:

jdub 06-26-2010 06:27 AM

Sounds like you got her dialed in. I'm sure you'll be happy with the numbers you see. Grab that hand held...and take a few pics. I'd love to be there but it just didn't work out for me...have fun!

Philm 06-26-2010 09:57 AM

Sorry man, I wish I could have come up there but the way my work is screwing me around I just couldnt plan that far ahead. First i was leaving on Monday, then it was last wednesday, then Monday again, now its NEXT monday. You didnt bring a handheld with you?? Come on man you are killing us here. :party-smiley-004:

you are spinning a 34" right? That puts you still at 107mph with 15% slip. You definitely have more in it. Another thing that you might want to think about it that these boats are so light, when you fill them with fuel they REALLY slow down. Figure 80 gallons of fuel is like 500lbs, or more than 10% of the weight of the boat. Mine would consistently run 5-7mph slower with a good load of fuel, sometimes even more if I had other crap on board.

I just cant believe how stable the boat is at 110...its like nothing. Gotta love it :coolcowboy: Thats 3 Kryptos with Saris Racing Engines now :evilb:

DonRoc 06-27-2010 09:40 PM

Im stlll having some issues. I am going to install a new ign box the 6al seems to not be cutting it. i will report more when its done

Philm 07-06-2010 10:01 AM

Any updates Don? Looking forward to seeing some running videos of that thing.

DonRoc 07-06-2010 10:56 AM

The engine is out of the boat, too much blowby.. I hate the mess and will not settle for anything less that perfection. We called Akerly & Childs to get some information as to how long the rings should take to break in. I recorded 20-38% leak down. They said due to the tool steel rings (best available the molly rings just dont hold up to the heat with a high boost motor), that even with a 280 grit finish the cylinders most likely broke in before the rings seated.
So yesterday we pulled it out of the boat and took off the heads, sure enough the cylinders were glazed. so we are going to hone it again as recommended by Akerly & Childs with the 280 grit. They are confident that the rings will seat this time. We will break them in, in the boat.
Also we noted #4 was clean, the Injectors are going on the injector test bench today to get flow tested.Even though they are new my hope is #4 is leaking down or hanging open. That would account for the tuning issues.
After seeing what we found I am very confident this will solve many of my issues.
The other option was run it and pull it down over the winter... Not an option. I would be stressing all summer wondering and would have been chasing the tuning issue. #4 may have solved it. There is definitely something going on there.
I will keep you posted

Philm 07-06-2010 01:00 PM

Damn, Don, that just isnt the news I was hoping for. Hopefully you can get it back together relatively quickly. Good luck with it.

Me neither, but glad its down now. Jason is on it now, I had to get back to work. I am very confident it will be back and much better. Maybe will pick up some HP... The o2 sensor was on the exhaust where the injector was having issues.. As we all know **** happens and in this case its nobody's fault. the cylinders just broke in a little sooner than the rings and they didn't seat. But I wanted and still want the tool steel rings once they do seat they will hold up better than anything out there. This is the risk its a numbers game and my number was up. So we hone it again and put it together, a good opportunity to take a look at things an how hey are coming together. everything looks great. I am waiting for a update on the injectors. I will let you know.
The plan it to have it back in the boat and running perfict before next Tuesday
