how fast is your jet boat?

[cyclone]

probably for most everyone here, its winter time and you aint boating any more. So all we got left until spring is talking about boats. So how fast is yours?

[steelcomp]

Um, this is V-Drives. :rolleyes:
Well, it WAS in V-Drives...
OK, my Bahner ran 11.23 at 93 at Ming Last year ('04) in the heat, and I've seen 97 at the lake. That was with the old motor and a full interior. Now I've moved the pump back, set a low profile intake, removed the interior and replaced with buckets, moved the seats back 6" and the motor forward 2", and went from an MPD prepped alum. B impeller, to an MPD prepped BC stainless and inducer. Oh yeah, I added about 200 hp. Hoping for mid to low 9's, in the 110+ range. :D

[Squirtin Thunder]

Um, this is V-Drives. :rolleyes:
Well if my boat was a v-drive it would run close to 90mph I would guess.
But that Bahner would be scarry !!!

[BigBlockBaja]

Just my 2 cents... I run an honest 65 mph with full fuel and a full cooler.. All bullshit aside...

[RCB19]

Now this one could get interesting...

[Squirtin Thunder]

Mine has GPSed at 78.3mph loaded but it has run 83/84mph on the Norskog speed prior to GPS.

[maxwedge]

Last time out, I GPS's it at just under 11MPH. I'm hoping it will go faster next year, now that I have removed the large rocks from the pump. :D

Well lets see.... I've decided to keep the boat and finish it. After all is said and done the boat should run 110+. i will say one thing and one thing only. 1400-1550 hp blown 632+ci. running on race fuel only :D
This is the boat. 1979 Spectra 20 will be in the water 2006.

No way....Your boat got a FAT ASS...Gonna take way more HP to get her ass outta the water...

[RICHARD TILL]

Steelcomp; there are a lot of the texas tunnels in this part of the country. a company called warhawk just across the line in alabama is making a copy now. they also are copying the youngblood tunnel hull and the tx-19. one thing about them is they will pitch your butt in a hurry. ---------------------bigblockbaja; you`re right..........

If you say so..... ohh by the way this informatin is coming from valuable sources...(Jack @ mpd... Gary @ GTeague..... ectttt ect....) the boat should do a solid 100 with 1000hp... this is proven, a buddy of mine has done this already. I think with 1400-1550hp this boat will do over 110. then again..... "I'll say it when it does it"... so for now, its on the trailer. :cool:

At Finnegans bachelor party my little shitbox ran 94 MPH up river @ 6200rpm with a GPS, since then we have changed a couple of things and it leaves much harder now, as for the change in speed, i could not tell you, im not at WOT that often, nor do i have a personal GPS!

i sure as hell dont have a personal GPS, but i just got back, and w/ the bigger nozzle in it, im sure i was doing 65..felt like it, but i dont know at all...ford 460 .30 over w/ an agressor pump. 76 eliminator. it was first time out, and the thing ran so well...i was VERY suprised!. thanx to all who helped me out on here...

[Liberator TJ1984]

at Marble Falls this year was my first time to ever race , so I know it can be improved.... :)
10.89 @ 98.9mph w/600# +- Hull and NOT STRIPPED down for races , just as she would be on the lake, under dash sterio,speakers , etc.... :crossx:

[riverbound]

My boat consistently runs 80-85 for hours at a time....of course that is on the trailer on the way to the river. If I wanted A go fast boat, I wouldnt waste my $$ on a jet.
My real world guess is my boat does mid 60's to low 70's. the whacker is a lot faster with way less HP and its much more reliable.

67.5 @ 4900 rpms and rising. Motor is a Blown Honda 300 cc that i took of my 4 wheeler, put on bigger cam, nitrous, 14:71, propane injection running on JP-8 fuel/vegetable oil 50/50 mix.

81.7 gps with full tanks of fuel. The sad thing is that I was only spinning 5000 r's. I will be cutting down the impeller and pulling up the r's where my mill makes the most hp. I should be in the high 80's next year;) Maybe I should do a rideplate and a shoe;) I wonder where that will put me....... :crossx:

Nope.....Look at the $$$ most of you guys have invested in your motors to get them run the speeds that are considered fast for a jet boat. Most of you have more in your motor than I have in my whole boat. and I will outrun most of the speeds posted on a stock 300 hp motor.
I have nothing against jets (I have one) Just never understood people bragging about speed and a jet. There are plenty of ways to go fast for less $$$

[76 Sleekcraft]

Not fast enough! That's my standard answer to anyone asking :) .
I've seen 86 on the gps, but never stayed in it long enough(with the gps in the boat anyway) to know if it's topped out. One of these days, I'll nut up and do some serious hammertime, gps in hand, and find out. Then I'll probably cry :cry: ...

[blender over]

Ill chime in here, my old jet went 94mph (best) on gps 800hp
My new o/b goes 84mph gps with 225hp
Go figure :p

My old Taylor SS, stock 454, Edelbrock manifold, Nicson Logs, Berk "F" pump, Alum "A" impeller, Pro-loader, 2 sets of Skis full interior, case of beer on ice, 2 anchors and a passenger (adult-size), ran 64 last fall @ 4800 RPM.

BUT just hope like hell your oil injection dosen't crap out/or plug up , and waste your powerhead , serious ,serious $$$$$$ to repair :cry:
really though , the oil inj.pump is ran off the crank via plastic plunger, as time goes on it wears down and thus pumps less oil, need to be replaced every few years ? at least what the OB mech. down here suggested

[Gearhead]

Ok since were on the fast topic. What is a safe speed for the lake in your opinions?????? When Im at 80 I have to get out of it because the water conditions get bad.It gets dangerous really fast. Whats a good speed??
Definately a good question and one that is difficult to answer. For me, it depends on a number of factors. Water conditions such as chop, rollers, waves, etc. Weather conditions such as wind and direction, etc.
Type and condition of the craft. Is it a high performance hull designed for high speed or just a nice lake boat being pushed to its limits? Some of the HP tunnels are very stable at 100 mph when some lake boats feel really crazy at 60 mph.
Then a very large factors is the boating conditions meaning how many boats are in the vicinity and how are they driving and what is their present condition and mindset. Is the course completely open, closed or what element of control.
Just as at the race track, the performance boat enthusiast needs to consider many factors of your path or course prior to beginning the pass and then be alert to changes as you ride.
The subject is as wide as it is long. But, to post an opinion... 100 on a public lake should be plenty to proove a point, but then again some boats should not exceed 80.... or in my 12' jon boat about 25 mph is more than plenty. For me it is all about acceleration. I like to go from point "a" to point "b" quickly in a short amount of time, then settle back and cruise.
Just some thoughts and an opinion.

[396_WAYS_TO_SPIT]

very true, I have seen plenty of 100mph boats on the lake that dont look too safe at those speeds......

[Some Kind Of Monster]

Im thinking we should be asking:
How fast is your Jet,
How much power are you pushing,
What kind of hull,
How much $$$ have you spent on it!

Is it really cheaper? How much does a brand spanky new Merc 300 hp outboard go for? $10,000? I'm thinking more than that. You could build a pretty nice big block for $10,000-$12,000.
I just found one on a search..........
New 2000 300 Promax in the box - for sale....$15,500.00 OBO plus shipping from Oshkosh, WI
And that's for a 2000? That don't sound too cheap to me!

The first three questions are very reasonable questions to ask a boat enthusiast or racer.........
But to ask "How much $$$ have you spent on it" is not a reasonable question and totally irrelevant. Too many boats, cars and engines to even think about such.
This is also a public forum and I would be afraid my wife or the IRS might log on. We have been happily married for 29 years and I would hate to have to train a new one.
Anyway you have heard the phrase... "Speed Cost... How Fast Do You Want to Go?"

Pull the pump and plug the hole. Mix your gas and oil. No biggie. Most high perf motors dont have them.
PLUS, you don't need a brand new merc 300 to run 100 plus. The motor on my old bass boat cost me 4500 and it would still turn 98-101 depending on water conditions.

[Hipshot]

My last boat was an 18ft Youngblood tunnel with a .060 over 427 11:1 compression Dart Pro1 heads, solid roller and tunnel ram w 750s. Berkeley pump with aggressor impeller, stuffer, droop snoot, diverter, ride plate and shoe. In good air with five gallons of fuel and just me in the boat 91 mph. Had about $10,000 in the whole boat. Best bang for the buck I have ever owned in a boat. It is pretty damn hard now days to put a jet boat together for $10,000 that will run 90 on the motor alone.

In the boat drags, the boats get a running start at the first timing light. That is why the ET is so quick compared to the mph. There is a countdown clock that tells you how long you have until the clock start's tickin, so you can leave the holding rope in advance as long as you don't trip the beam at the begining of the measured 1/4 mile before the timing starts.
Hope that helps,

Fuel lines? My guess would be a seprate fuel input for a "wet" nitrous setup. The motor might be a pump gas deal but when the n2o is hit it sprays in race fuel. But this is just a guess. :rollside:

Looks like 2 four port regulators, a Y block, and triple bypass.

Yes you guys are right on the nitrous and lots at that. That is a product engineering dual reg set-up and by-pass Im also running there pump. the reg and bypass im using so there is never any deadheaded fuel pressure and it also keep the fuel cooler and stops fuel spikes.http://www.***boat.com/forums/attachment.php?attachmentid=10005&stc=1

Can you explain how the three bypasses work. Why is there one before the regulators and one on each regulator. I always thought you could not run two bypass regulators on the same fuel pump. Aeromotive says that if you have 2 bypass regulators on the same fuel pump, the pressure of the system will bypass to the regulator set at the lower pressure. How is yours set up to avoid that?
I can make out a fuel line in, one regulator goes to the two fuel solenoids, one goes to the carb inlets and three bypass lines. Whats the second bypass line on the regulator on the right for? Whats the other two braided lines behind the regulator for?

[TRG]

Did Someone Say Tea Bag...
Oh Nice Motors. When Are You Gonna Be Able To Hold A Cooler?
YOU CALLED??...I can hold a cooler just fine!

[slowasscp]

taylorman the other two lines behind the regs. are water outlets from the manifold. and the bypass regs have different jets in each reg to compensate for the pressure difference.all that fuel sytem is Product engineering stuff
they have some badass race cars that are using 1000hp nitrous so im not to worried about the fuel system and John at PE is very helpful.

Yep, they did ... 120.16 @ the 1/4 ... Mike had to get out of it as we 'Blew The Tail' (Too Much water in the pump) at the Big End and became somewhat unstable ... Most jets are starved for water on the big end ...we're having to figure out how not to have to much ... go figure, we spend a year and one half trying to get water in the 'Hole' ... Now we've got to figure out how to optimise/minimum it on top ... just another problem to solve.

yeah mike pop down for one of the sonny's hemi's eh?

[UBFJ #454]

If you look closer, I think you'll see that's a MOPAR HEMI (actually a Semi-Hemi) and not a Sonny Leonard Motor ... Leonard's Hemi Heads (also Semi-Hemis) are for blocks based on BBC Design.

[Taylorman]

Whats a semi hemi? What is a true hemi by definition?
So that picture is a BBC with hemi heads?

Shouldn't this go it what happend to the Aggressor thread ???

[UBFJ #454]

Sonny's heads are for blocks designed on variations of the original BBC design. True Hemi's have combustion chambers that are truly hemisherical with the valves up on top ... like the old 392's & mid 60's 426 ... semi-hemis like the new MOPAR HEMI and Leonard's heads have combustion chambers that are not truly all hemispherical and the valves are positioned somewhat down, to the side from/of the top of the chamber ... a slight difference, but none the less, a difference. Leonard's Hemi Heads are for 5.0 cylinder spacings ... Everything gets Expensive when building/running a 5.0 spacing motor.
Not knocking the newer design at all ... just prefer the older true hemispherical design ... would eventually like to build & race a 500 cid, 5.0 spacing motor with true hemi heads, but, that's not in our motor program right now due to what we've already committed and costs of a new motor.

[Taylorman]

So the difference is in the combustion chamber design. Anyone have pictures of a true hemi chamber vs the new stuff?

[UBFJ #454]

"So the difference is in the combustion chamber design."
That and valve angle(s).

[Taylorman]

I found a few pics. I think these are true hemi heads. Why are hemi engines not as common. I bet one in a jet boat would be bad ass.

Whats the wieght on those cast iron monsters ???

[UBFJ #454]

"Why are hemi engines not as common."
Mainly due to cost & availability of parts ... in the old days, many more GM motors were manufactured than any others so people could get them more readily and cheeper. This carried over to now where many more aftermarket parts are built and available for GM products ... principally variations of BBC design. Same thing as with BBF motors.
The whole thing boils down to Supply & Demand and ... Cost.

His motor was wrung out to the point that it didn't last the season and it's a race only boat. Never brought out to the local lakes. I took Rich's boat as being as fast and quick as they get without nitrous and his motor was fresh when we raced.
I've never seen a nitrous injected outboard on a local lake. I was told that they only last for a matter of minutes on the nitrous.
I know you know your stuff on the outboards but somehow what you portray is not what I've seen and heard from my friends with outboards. It's great that you know how to piece them together cheap but I think most guys spend the real long green on them.

How do the outboards stand up to nitrous? How big a shot
can you run with em? My BBF has four seasons and lots of
bottles run through it and seems to be hanging in there pretty
good. I'm only running a 150 shot on it, and it was built for it
(forged pistons, total seal rings gapped for the juice). Just
curious as to the skinny on the eggbeaters and juice.

Berkeley pump with aggressor impeller, stuffer, droop snoot, diverter, ride plate and shoe. In good air with five gallons of fuel and just me in the boat 91 mph. Had about $10,000 in the whole boat.

A progas race boat is not going to be the fastest on the lake. Lake boats don't have to follow rules.
I don't know why his motor did not last all season, perhaps
his choice of gears, prop, or some other reason.
As far as nitrous goes I don't think it helps the life of any motor. How big a shot and how long you hold the button down has a lot to do with how long the motor lasts.
