Hey bro , Your right sounds like you have been pretty busy... That lifter issue had to suck.. Hopefully you guys get a try at it again tomorrow & all goes well !! Keep them Lifelines on & be Safe !! That boats destined to be one of the all time baddest open canopied pleasure v's in existance.. I gotta say I loved that boat first time I layed eyes on it back a couple years ago & ofcourse that love has grown a bit more recently..:cool: I need to get out there sometime & check it out in person.

Thanks for the quick reply, im sure we can all understand the issues (if it was easy everybody would do it). What type of oil did you run during break in? Were you planing on running something other than 20/50 after that point? Look forward to hearing about more testing & seeing some pic's of the new work.

Can't wait to see your updates, get us some nice videos and speedo shots.

Scott,
Thanks bud. Come on by whenever you want. You're always welcome. I agree, it is a beautiful boat. One of the better looking ones. I replied to your distributor thread. The lifter deal did suck. Always got the Lifeline on in this boat.

I did plan on continuing to use the 20W50 oil. These lifters are made to run much more rpm(7800 rpm) and more spring pressure(550-575 lbs) than the average hydraulic lifter. The problem was that the clearance in the lifter between the cup and the body is only .000025(25 millionths of an inch). That space is to tight for 20W50. Once the oil made it in, it could not get out. They had to build a special set with larger clearance to be able to run that oil. I was able to sneak the lifters out without taking off the intake What a bit@h.:mad:

The weather isn't looking very good for tomorrow. Calling for 20-30kt winds and possible strong storms and hail. I still need to spend some time fine tuning the program before I really stand on it. The wideband on the dyno was showing a lot leaner than it really was, so now both engines are on the rich side. The dyno headers were pulling air into the collectors from around the primary tubes, hence, telling us there was more oxygen in the exhaust than there really was. So, I richened it up on the dyno. When it went in the boat, that oxygen wasn't really there, so the engine is now on the rich side. It's not much, but it takes time to map two engines all the way through the rpm band. I wanted to wait until I got the right props on it to tune it with enough load. I will definitely get some video when I run it. Thanks guys.

wow. good knowledge on this thread. How did you know that the lifters were to tight? Was this something you knew all along and were just experimenting with, or what was the clue that let you know this was going to be a problem?

No I didn't know. Unfortunately, I had to find out the hard way. I knew that something was going on. I started hearing some valvetrain noise on one side and the engine started to idle a little rough. I did a comp test and one bank was down about 40 psi across the board. It was because the lifters would not compress at all and they were actually holding the valves open a little. The other side was making some noise because the lifters would not pump up, since the oil could not make it into and out of the lifter. I called the manufacturer and they had just ran into this problem the week before with another set. The first questions he asked was what oil am I running. He immediately knew the problem. Luckily, someone else had the problem before me. It took them a while to figure it out. The lifters were designed primarily for circle track were they turn a bunch of rpm.Those guys can get away with running a 10w30 or 10w40, whereas, the marine side can't.....or don't want to. These are the only lifters that I could get to live with this combo of camshaft, spring pressure, rpm, etc. Several years ago I tried everything else out there and while they did great on the dyno, as soon as they went in the boat, they would fail within a couple of hours. The plunger would collapse. In order to run the cam I'm running, I need quite a bit of spring pressure to keep the lifters on the cam. Rpm isn't much of a factor since I'm only turning 6400 rpm. The biggest factor is the steepness of the ramp of the cam. It opens and closes rather quickly, so I need higher than normal spring pressures. However, it still beats a solid roller. I can get well over 100 hours from the valvetrain.
We have it covered now. It's ready to run.

Tuning issues, valve train issues, dry sump tank issues, what else will happen when you actually run it. Glad I am not the guinea pig on this project.

normally I wouldnt say anything...but..I feel threads like these are positive in teaching us all something. This is what happens In the real world.. turning something that doesn't always go as planned into a positive project..If it was easy all the time..everyone would be able to do what Eddie has done. I think it's great posting the good points as well as the little hic-ups that come along the way..who know's it might help someone down the road...Thats what you should have done on your last negative 18 posts with Dean/Taod, worked it out. Being negative all the time will bite you in the azz sooner or later. Jeff

Nice job Eddie and thanks for taking the time and helping us out on the phone :ernaehrung004::ernaehrung004:

Just repeating the facts in his post.
