Jack's pro no question.
But "a steady 6700 rpm on a b cut" tells little about performance. After all, a rebuild on a leaky pump will reduce your rpm's at the same power. Are you saying 6700 rpm's after rebuild are better than say 6500 rpms before? Or did you turn say 6900 rpm's before rebuild and are glad that now you only turn 6700 rpms? Or did you make changes to engine power also? By what measure are 6700 rpm's proof of pump health or performance or a "pro" rebuild?? Rpm's alone don't mean sh*t.
My thought? With a PC, your jet no doubt runs fast. If you want to be mysterious fine, if you want to share info then post mph as well as rpm's. Otherwise, comments on how good your pump rebuild, tune or setup based on rpm's alone tell half the story.
Just curious.

Easy man......He was just commenting on how happy he was with Jack's work. Nothing more, nothing less........ COngrats on the pump man:)

I'm happy with Jack's work too. But the measure of "performance gain" or "how great Jack's work is" has little to do with rpm alone. In fact, Jack's work can reduce rpm's or make them smaller than before he did the work. Djd quoted rpm as the sole measure of goodness and performance or the worth of Jacks mods. Without a baseline, corresponding speed and/or et change, that means nothing. So I commented.

djd placecraft is the one taching 6700 rpm's. My boat runs out at about 5,100 and pulls to a gps proven 78 mph. Jack coverted my C bowl to a G, added a droop, shoe and rideplate, loader grate, performed a stage 1.5 blueprint, and completely rebuilt the pump with an AB Impeller, new wear ring, bearings etc. I had the bottom of the hull blueprinted by Jeff Bennett and the new motor dyno'd out at 533 hp at 5100 and 599 ft/lbs of torque at 4300. Its a nice running/solid package and I am very happy with it!

Just stoked to see what he did for me nothing more nothing less!I am not going to get into this posting speed crap so people on here can go to bashing on me.If you are that interested in what it is and what it does come to ming in sept.
HB possibly 1000 on a real good tune up this weekend was a weak tune up.Timing was locked at 22 deg. and the motor was pretty fat.We never did mess with the shims at all.

DJ- he wants to know how fast your boat goes. LV just doesn't have too much tact when it comes to these things.
I'm going to say that when you hold your foot down for a full 10-seconds that you'll run 110-112 mph. Am I close or have you already done that? I'll be at Ming in september as well. we'll have to toss back a few colds ones friday night. Good luck and glad to hear the boat is finally back on the water.
Oh yeah, are you going to CBBB again?

I run a manual valve.I am pulling the blower off and the intake to check the intake gaskets.Its more than likely is gonna be a head gasket.The cam specs are .734 x.734 lift .276x.286@50 on a 114 lobe center.

When are you flipping the valve open? any cam with more than .248 at .050 is capable of producing reversion. I wouldn't open the valve at any RPM lower than around 3k with that bumpstick!

At first sounded mysterious to me. Like v-drive mentality, "Don't know don't care, just got this one big tach on the dash and I'll beat your ass" Ya whatever. But after reading your other post about only running an 1/8th, the real answer is you don't know? Nothing wrong with that why not just be honest and post. I would.
"I am not going to get into this posting speed crap so people on here can go to bashing on me"
They won't bash on you for long (or at all) if they sense your numbers are true. If you're worried about posting speed for bashing then don't post rpms either. They're both numbers. You could be bashed for rpms if your sensitive to bashing. I've posted both and people don't bash me on numbers I think they know I can back mine up...in fact I welcome a challenge or I wouldn' post numbers (speed or rpms) in the first place. My numbers good I don't worry about bashing those who do look stupid. Besides, are you REALLY concerned with people bashing on you? C'mon. It's only the internet geez.
berk lamely posts: "LVjetboy do you ever leave your pc? get a life and stop starting fights. maybe he doesnt give a shit what you think about his speed. not everyone wants to brag and talk numbers"
Excuse me? 6700 is a number posted by djdplacecraft in the first post to this thread. And don't tell me 6700 isn't a number worth bragging about. It certainly is. Can you top that? IF he doesn't give a shit about what I think about his speed or numbers, then why worry about bashing? Maybe YOU should get a life? Try again.
"LV just doesn't have too much tact when it comes to these things"
You're right, I have no tact and not interested in getting some. I want to know as much as I can about true jet boat performance w/o the macho hot boat i'm a wanna be racer secret bullshit you know what I'm talking about. Sometimes you got to filter thru that crap to get to true performance. Is anyone else interested?

Jer, Jer, Jer. Tact remember? I didn't see any "wanna be racer secret bullshit" coming from DJD.

Bense no it wasnt sean it was a buddy of his with another gullwing with a 540 on the juice.The guy said that it ran 97 on the motor and 110 on the juice!I dont know how much truth their is to that.You guys should have stopped by and had a cold one or twelve.
LV I thought you were a pretty inteligent guy most would figure that if jack just did the pump like i stated and set it back that you would know that it should be pretty tight.A profesional job!!!!!!Not a sloppy job.And i believe that i did state that it was a b cut stainless impeller.Isnt it you that has the fancy stuff that figures out what all that should mean?Maybe not,maybe i have you confused with someone else!Either way have fun with your computer and we will see ya at ming!

"LV I thought you were a pretty inteligent guy..."
So maybe you thot wrong. :)
"most would figure that if jack just did the pump like i stated and set it back that you would know that it should be pretty tight. A profesional job!!!!!!Not a sloppy job."
No doubt, that's why 6700 means nothing in tight or sloppy unless you state a baseline...or how many times she did it.
"And i believe that i did state that it was a b cut stainless impeller.Isnt it you that has the fancy stuff that figures out what all that should mean?"
B cut makes a difference, stainless or aluminum not so much. Sure I got fancy stuff, here's my guess...
PC at 6700 rpm on a Berk B = 110+ mph. Depending on setup and weight of course. But my original point was, 6700 alone tells nothing about pump rebuild quality or setback, and only tells half the story about performance. In fact, rpms alone don't tell much. But v-drivers still have that one huge big-ass tach on the dash...nothing much else.

6700 on a sloppy pump means nothing.6700 on a tight pump means something to me.OH there were 5 short passes in a row.The recall said 7400 on one but i stood on it out of the hole and it sucked some air.

You KNOW I'm interested. Very few PC's out there. And when I comment, you know I say what I think. Not meant to attack you or your results. Just my no bs opinion.
On porpoise, low speed in the rough for my PlaceCraft way better since setback and ride plate mod. I also put the 4 degree down wedge back in for more negative diverter control. But...I may still have a very slight porpoise above 95 mph haven't checked yet with the new plate. I'd be interested in how yours handles 95-100+ in smooth water...among other things.

jer [/B]
The porpoise issue was the best result all in all.I still have a porpoise but not nearly as violent as it used to be.The porpoise starts at about 3000 rpm and carries till about 4000 i dont know the speeds at those rpms but that is where it is at.At the unknown speed of 6700 there is no porpoise at all what soever.I have a wedge but i was going to wait and see what we get out of the boat with shiming the shoe and ride plate.I also have the motor set fwd allmost 1 1/2 inches.

LVjetboy

07-11-2004, 03:04 AM

Sounds like your rpm's for low speed porpoise similar to mine. High speed? For me seems driven by speed more than rpms. Once above 95 a very shallow porpoise. Nothing crazy but not the ideal setup I'm sure. I'm wondering...

I have never felt any topend porpoise at all even before the setback.I still have'nt put the wedge in did you gain anything when you installed it as far as ride or speed?

LVjetboy

07-11-2004, 09:56 PM

I didn't feel top end porpoise either till I exceeded 95. Then on smooth water 95-100 a very slight porpoise. Small enough to seem water surface induced but maybe not.
As for wedge, no speed gain but ride improvement yes. The extra water bending has got to affect thrust but not enough to notice overall with my setup. My wedge's 4 down now so that adds to PD down trim. Ride in the rough with full down PD noticeably impoved still not perfect. Since my full-up trim stop's short of full-up, I'm thinking of trying a bigger down wedge for better handling in the rough.

The rough water stuff i dont worry about cause we usually hang out on the lower end of the colorado where there isnt much traffic.Last year the boat ran in the mid 90's with a natuarally asperated motor i never felt anything as far as a porpoise at those speeds.There are a couple other guys that are running the pc down where we go but the are blown injected on alchohol and running a little faster than me.I have also talked to them about it and neither one of them has had that problem,and one used to owne placecraft boats and still ownes the mold on the new style hull.But they both do porpoise at low speed.I was told that they do it cause at low speed they dont pack enough air under them due to shallow tunnels.
