Misery loves company.. Thats why all the jet boaters have to create controversy, so they can get thier fellow boaters out to talk about thier problem(of buying a jet) Its ok, sucking gas and going slow is an equal trade for having reverse in a boat. Boy, must be embarrasing to shoot that jet spray way up in the air only to imitate a REAL v-drive hydro on a smokin pass. I've never been in a boat going sooo slow with such a big rooster tail..??.. Man, where can I get one of these? I guess I'll just convert my v-drives over to jets and use the tranny.. anyone done this before?? oops, guess it goes only the other way around.
BTW. All in fun..no one get butt-hurt over this please.. I LOVE ANY KIND OF HOT BOAT!

Kurtis500,
We create controversy so you prop guys can take a break from your boring and slow-ass forum to have something interesting to read. Misery seeks consolation?
No we don't use a "tranny" because jets convert horsepower to speed without the $$$, hassle, limitations, or complications of a gear and friction-filled, heavy transmission.
Of course the only v-drive I've raced I beat. So my experience is limited. Didn't even need to hit the bottle. Could've been a fluke I admit. Must've been a v-drive LAkE boat? Similar to my LAKE boat? Or are we comparing RACE boats? My bad, I'm confused and forgetful these days.
Oh, and BTW, I roosted one of those fako jet sprays while I beat him (Lake Mead, shootin' the narrows, headin' SW to Calville Bay. Later we chated at the dock) Nuff said?
The part about converting your v-drive to a jet...good idea. Just dump the tranny. Even better, buy a hull made for a jet, pop in your engine, and FEEL the speed!
All in fun too of course, no big deal, v-drivers don't take it personal, etc. etc. http://free.***boat.net/ubb/smile.gif

You're comparing a blown fuel v-drive drag boat to all jet boat's ?
Ok, I,ll take that challenge. First I'll run him at the drag's and he will beat me by 5+ seconds. Then he can run me for 20 miles down this winding narrow river where I boat at. Ok, there might be a few shallow spots and submerged stumps. Then I will beat him by hours because he will never show up at the end.
If we're comparing boats and drives lets at least talk about boats in the same catagory. It seems that the v-drive guys just want to talk drag boats. Well the
v-drive's are the fastest at the drags and that's a fact. But since I don't run the drag's that's not a factor in what boat I would choose to run for recreational use. On this boat forum there are probably only 1 drag racer for every 30+ recreational boaters.

If you put the same motor in a jet and in a v-drive. The v-drive will be faster. They both have their goods and bads. It is just whatever you prefer. I had a jet boat for 5 years and now own a v-drive. I have a great time no matter what boat I am in. Remember, have fun!!!!! Lumpy

The guy I bought my 19' Cheyenne jet from went 98 mph at the drags with a 454 nitrous motor in it. He put the same engine in a Sanger flat and went 88 mph at the drags. This is a fact, I seen the boat run.

Mark there is no challenge; there must be a creative imagination at work. The remark (a twin prop boat) I wonder how fast he will be just making some part throttle passes vers any jets on a full pass?was in response to other postings like this.
Oh yea, I remember, the prop board is slow and boring, just like a prop boat. LMAO(j/k)propees"
I don't think we want to start a flame war here but to imply that prop boats are boring I felt needed a response to some of the Jet guys who are capping on props. I own a prop & like jets to, but different propulsions are best suited to the needs of the water or owner. If you are prompting some sort of challenge your swimming up the wrong creek. You want to race offshore or in the bay for some distance like 20 miles as you referred to? I bet I could find a prop owner who'd take you up on it! The only time a jet will be faster than a prop is in shallow water or water with debris like you are referring to. Jets are fun cheep thrills but if you really want to step up, a prop is it in most all cases! I wouldnt call that boring. It's funny I don't remember hearing of Jets in Offshore boats or even in salt water??? I wonder why?

Lvjetboy, That fako rooster tail must have been quite a sight! Was the v-drive boater upset with his equipment after that?
We v-drivers come over to the topless--uh, I mean-- jet boat board to humor ourselves. Here we can play in the sandbox, drop our load, then go back to the pleasant atmosphere of the v-drive forum. http://free.***boat.net/ubb/wink.gif But good thing they made the jet guys a second place to talk seriously.
Besides making a fast boat slower, the only REAL conversion of a v-drive to jet would be money into gas. On top of all this, v-drive hydros ride with less equipment in the water than a jet. Half a prop, a couple inches of rudder and maybe an inch or two of fin on the sponson. Thats how you fly.
We could talk in categories about the boats, but Wildside is in a category a jet cant achieve. But since there is one Wildside and thousands of jet boats its not really a comparison.
Still, all in fun http://free.***boat.net/ubb/smile.gif

once again, there are a couple clarifications needed.
first, charlie fagan does NOT (repeat, DOES NOT) discriminate between flats and jets. the 7.70 rule applies to both. yes, hangfin has the pgf record below that, just like dan has the bgj record below that. both paid for it through D/Qs; tony probably a little bit more via marie calenders (and if you don't know that story, you'll have to ask tony or jeff). you'll also notice that neither smackdown OR flat nasty are running ihba anymore.
second, jerry hicks runs comp flats all the time in the brackets, without the bottle (illegal in brackets). if you really want to run against jerry when they have the bottle in the boat, just jaunt on over to chowchilla in a week, or ming 9/7, and we'll see what can be done to accomodate ya. sounds like just another young whippersnapper needin' a lesson.

THATS BECAUSE WHO EVER HAD THEM SOLD THEM ARE CRASHED IT. VERY DANGEROUS BOATThats Old School- It was the Hull Design, method of load which caused that. You can not shoe below the keel line and not expect to go crazy - If you do and they did -you will barrel roll, swap endsand god knows what else. Jets acceleration when all is said and done,jets
will always out the prop and thats a fact.
In a Jet when you combine Torque/HP/RPM the water cannot slip off -It is incased and must go for the ride.
A Jet is not torque transfered by prop load as in a Prop which twists everything contact direction
It locks water while still retaining the same frontal type pull as a prop. A jet has a smoother transistion all the way through the ride pull to thrust pressure. (Thrust Pressure-something Propers don't know about)
What Jets were lacking has and is being changed today in both product pump design and hull changes.
Todays builders have learned how to load smooth and hard with very safe hardware. Shoe's are up and in, no below bottom shovel drag is going on now and the hulls are able to Lock & Load.
The "Calif Get Wet & Texas Pitch Out Boats" are
becomming a thing of the past. Don't get me wrong I understand why these boats are ran because of there quickness on lower HP,the driver took a automatic attitude he is going to get wet. It is this group that was the reason Jets did not die in the 80s/mid 90s. I don't think I know a builder today that did not get pitched- But Jets
under these conditions held propers off in many classes.
We are the new kids on the block and things are more in favor for us than you. Engine builders are your worst enemy- Jets need Torque-Look at the stats-60/70s HP to Torque- 250 HP= 160fpt
Today- 250HP 255fpt it favors us. You can't use harsh torque- it make you twist & dig. WE CAN AND WILL! Your Cowboy days are numbered.

4.70 e.t. at 245mph. Once achieved by a jet :rolleyes: I will then feel our days are numbered. And only then, will a jet have strived soo hard to become merely equal to what will then be an old record to prop boats.
I'm no hydraulic engineer, but at a certain point it seems there is going to be soo much water forced out the jet discharge nozzle that friction loss becomes too great a factor. Have you done any work on this friction loss stuff?

I'm no hydraulic engineer, but at a certain point it seems there is going to be soo much water forced out the jet discharge nozzle that friction loss becomes too great a factor. Have you done any work on this friction loss stuff?Kurtis- I Miss you DUDE- Yes to your discharge question But very small size changes. size. 3.125 to 3.250 say as a basis at 135 pounds pressure at the nozzle output- Thats a lot of water. (bowl pressure at 550 pounds).
A impeller has forward pull just like a prop. Thats the biggest change going on now- Design the impeller to pull harder & longer- Design the bowl to flow with higher flow rates while maintaining water control-This has shown a decrease in bowl pressure at the same time. Our 11 vane is just now starting to be understood by few but back east it is working well. and flows some 58cfm over our 9 which is up 40cfm over the old bowls.
So much attitude change has had to go on- Small impellers high pressures-Now bigger higher flowing impellers (forward motion)and higher flowing bowls with decreased bowl pressure. This allows the pump to vacate quicker putting the demand on the forward motion side of the impeller-More demand. This caused Nozzles systems to be opened up to allow the water to volumn to the choke point. Just like a Shot Gun. Further Proof of this is our Big Mouth Impeller- It loads bigger and harder yet!
Don't get me wrong this is the basis for much higher Torque, which the builders are now starting to exceed 1x1 to HP.
As to Props you guys have 100 years on us- Yet I see no reason to not Out ET you in the end on a measured course. We can not fly loose & never will- We can lock the water into the system and let the pump work more efficient to the motor than a Prop. So there- Just a Kidder!

Question here, Has there been any thought to running two impellers in a series? Fire trucks have pumps which can swith the 2 impellers from a side-by-side position (Parrallel) to a in-line position (Series). The Parrallel set-up will discharge more water by volume at a lower pressure and the series will send less water but at a higher pressure. Maybe counter-rotating impellers?

The Parrallel set-up will discharge more water by volume at a lower pressure and the series will send less water but at a higher pressure. Maybe counter-rotating impellers?The Fire truck has a completly different impeller- Frontal inlet is the same, However it has long internal vanes exiting 90% which gives the water a longer ride on the impeller- the bowl is much like a rotary lawn mower comming to the exit port. This is a horizontal Pump vs a Vertical Pump Like we use. One of our guys here keeps saying he is going to put a modified horozontal version of this thrust pump into a boat. Some 30+ years ago, he was involved with a tube bowl (series of stacked tubes inside a housing) and it thrusted above water line. It Hauled Buns. I will follow up on your thought- See what that industry is doing-
I think what you are saying is done thru valves and plumbing. We Make for Potter Romer which produces a fire line.- not aware of this shifting impeller design.I have a Question: A Prop is Dia. Cup and Pitch- the 3 eliments- We are playing with the same- It only makes sence to me, that a impeller can outperform a Prop- "Im not jesting here" If a Impeller can deliver the same pull bite(forward motion -Volumn & Pitch) with no yeild loss vs a prop with a yeild loss of something +- & assume you have the Beans in the motor to deliver it at the same RPM it must win.
The prop must always take a set before it can deliver true force.
You will always have a smaller wetted surface, cannot beat flight so you will always out MPH "thats a given", but our constant "G" load should out pull yours and in the end E.T.
I am not speaking of Hull design- Tunnel is the closest we, today can get to a hydro design.
I sure Like & see some future for Jets in a design like Jim Falkerson used. It completly wipes away the lift factor, yet provides a stable platform for big power. Take Care.

Ok, hull efficiency besides, what's the chances of a jet out-running a prop in 1/4 mile drags?
Pops1, your posts hard to follow, either your knowlege far above mine, or my post reading comprehension limited this time of night, or some combination of the two. Never-the-less I enjoy reading them...so post away!
Kurtis500, I think you nailed it with friction losses on the top end. Although the "channeling effect" of a pump may dominate on the low end?
So my question, which will dominate 1/4 mile tech advances in the future? Unlimited distance, prop every time in my opinion. But limited distance, maybe not since acceleration is a key? And who's put more R&D into design over the last decade...props or pumps? My guess is pump guys are lagging, although just a guess.

I am not quite what to make of Pops post either. I am still hoping that he will accept the grudge race challenge. In Chowchilla the comp flats ran in the 7.40's and one gas boat ran in the 7.40's as well. It looked as though the squirters were a little slow in the heat. Come on Aggressor, step up!! Accept the challenge and take your whoopings like a man. :D :D

Canuck 1, you sit there on the banks of the river until the water has completely dried up. Then give me email and we can set something up. Don't leave the bank until it's time. be patient :cool:

Now Don't lay back on me. Give me a hand to put some of these together. I will do everything I can to do this- I would love to see this and the time for a Annual should start now as you still should have the lead. HELP ME OUT -888-246-5075

jerWe are saying the same- Friction loss is true-You Tail walk "Jet can't". You can not pull as hard. Slippage vs enclosed. Prop-to Impeller.
Im not sure where you go after choppers! We see a long development ahead on our side- We took too big a bite this year in tooling to get it all done. I rattle so wake me up when I go on. See Ya
